Description

Optical module and electronic device including the same

[0001] The present disclosure relates to an optical module and / or an electronic device including the same.

[0002] With the advancement of electronics, information, and communication technologies, a variety of functions are being integrated into a single electronic device. For example, smartphones incorporate functions such as communication, audio playback, imaging, and electronic organizers. Furthermore, with the installation of additional applications, even more functions can be implemented on smartphones. As a single electronic device becomes more diverse, specialized electronic devices like electronic organizers, multimedia players, and compact digital cameras are being replaced by multifunctional devices like smartphones.

[0003] As diverse functions are implemented within a single electronic device and people carry and use them on a daily basis, users increasingly demand ease of use, portability, and high performance (e.g., fast information processing or high-quality images and audio). For example, electronic devices are incorporating increasingly sophisticated displays and speakers to deliver higher-quality images and audio, and the performance of programs and integrated circuit chips for processing image and audio signals is increasing.

[0004] In miniaturized electronic devices such as smartphones, improving the quality of captured images or videos can be challenging. For example, while cameras equipped on electronic devices can improve the quality of captured images or videos by incorporating high-resolution image sensors, there may be limitations in integrating lenses (or lens assemblies) that simultaneously satisfy telephoto, wide-angle, or macro capabilities into the miniaturized electronic device. By integrating multiple cameras (e.g., a telephoto camera, a wide-angle camera, a macro camera, or a portrait camera) into a single electronic device, the quality of captured images or videos can be improved while miniaturizing the electronic device. For example, implementing a single camera with good telephoto, wide-angle, and / or macro capabilities requires a large number of lenses and a mechanism for adjusting the relative positions of the lenses, which can be difficult to integrate into a miniaturized electronic device. On the other hand, combining multiple cameras with different angles of view can improve the quality of captured images while making it easier to integrate into a miniaturized electronic device.

[0005] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art in connection with the present disclosure.

[0006] According to one embodiment of the present disclosure, an optical module and / or an electronic device including the same may include a first substrate, a light-emitting element assembly disposed on the first substrate and configured to emit light of a specified wavelength band, a light-receiving element disposed on the first substrate at one side of the light-emitting element assembly and including a first detection area configured to receive first light emitted by the light-emitting element assembly and then reflected by a subject, and a first casing disposed on the first substrate and configured to provide a second receiving space accommodating the first detection area, a guide structure disposed between the light-emitting element assembly and the second receiving space, and a second partition wall extending from an inner surface between the guide structure and the second receiving space and disposed to face the light-receiving element. In one embodiment, the light-receiving element may further include a second detection area provided on one side of the first detection area and disposed at least partially inside the guide structure. In one embodiment, the second detection area may be configured to receive a second light guided by the guide structure that is part of the light emitted by the light emitting element assembly.

[0007] According to one embodiment of the present disclosure, an electronic device may include a housing, an optical module disposed in the housing and configured to emit light of a specified wavelength band and receive a first light reflected by a subject among the emitted light, at least one processor, and a memory storing instructions that, when individually or collectively executed by the at least one processor, cause the electronic device to calculate distance information to the subject based on at least the first light. In one embodiment, the optical module may include a first substrate, a light-emitting element assembly disposed in the first substrate and configured to emit light of a specified wavelength band, a light-receiving element including a first detection area disposed in the first substrate at one side of the light-emitting element assembly and configured to receive the first light, and a first casing disposed in the first substrate and configured to provide a first receiving space for accommodating the light-emitting element assembly, a second receiving space for accommodating the first detection area, and a guide structure disposed between the first receiving space and the second receiving space. In one embodiment, the light-receiving element may further include a second detection area provided on one side of the first detection area and positioned at least partially within the guide structure. In one embodiment, the second detection area may be configured to receive a second light guided by the guide structure that is part of the light emitted by the light-receiving element assembly.

[0030] By utilizing distance to a subject (or depth of field) information, the quality of captured images or videos can be improved even in miniaturized electronic devices. This distance information can be utilized to implement security features such as user facial recognition. For example, distance information can be detected by emitting light (e.g., infrared) from an electronic device, receiving the light reflected by a subject, and measuring the time between the emission and the reception. For example, an electronic device can detect distance information to a subject by including an infrared light source and an infrared receiver. Infrared laser light can be effectively utilized to measure distance information to a subject. Emitting infrared laser light can generate high temperatures, and if the operating environment changes due to the generated heat, the distance information for a subject at the same distance can be detected differently.

An active element or a passive element different from the driving circuit or the light-emitting element (373d) may be disposed on the second substrate (373a). In embodiments, the second substrate (373a) may be made of a ceramic material (e.g., LTCC or HTCC). For example, the second substrate (373a) may be made of LTCC or HTCC with high thermal conductivity, thereby quickly dissipating generated heat (e.g., heat generated by the light-emitting element (373d)) to another structure or another area.

[0097] According to embodiments, the light emitting element assembly (373) may be disposed on the first substrate (371) through surface mounting technology (SMT). For example, the light emitting element assembly (373) may be assembled on the first substrate (371) with the driving circuit and the light emitting element (373d) disposed on the second substrate (373a). In embodiments, the light emitting element assembly (373) may further include a second casing (373c), thereby preventing the light emitting element (373d) or the integrated circuit chip (373b) from being damaged during the process of assembling the assembly on the first substrate (371). For example, the second casing (373c) may be disposed on the second substrate (373a) while housing the integrated circuit chip (373b) and / or the light emitting element (373d). With the second casing (373c) placed, the second substrate (373a) is at least partially exposed to the external space of the light emitting element assembly (373), thereby allowing heat generated inside the second casing (373c) to be moved or released to the outside of the second casing (373c).

[0098] According to embodiments, the light emitting element assembly (373) may further include a first guide hole (373g) provided in the second casing (373c). The first guide hole (373g) may be disposed, for example, between the light emitting element (373d) and the light receiving element (375) (e.g., the second detection area (375b)). In embodiments, a portion of the light output from the light emitting element (373d) may not be emitted outside the optical module (307) but may be reflected or refracted by another structure inside the second casing (373c) and guided to the second detection area (375b) through the first guide hole (373g). In embodiments, the position or size of the first guide hole (373g) may be implemented in various ways by considering the relative positions of the light emitting element (373d) and the second detection area (375b), and / or the path of light reflected or refracted within the second casing (373c).

[0099] According to embodiments, when the light-emitting element (373d) emits infrared laser light for detecting distance information, the optical module (307) and / or the light-emitting element assembly (373) may include optical element(s), such as a diffractive optical element (DOE) (373f) and / or a collimator (373e). For example, by providing optical element(s), such as a diffractive optical element and / or a collimator, at least a portion of the light output from the light-emitting element (373d) may be guided or aligned in a designated direction. Here, the direction in which the output light is aligned may refer to the direction in which a camera (e.g., the camera assembly (207) of FIG. 4 or 5) is directed when photographing a subject. In embodiments, an optical element such as a diffractive optical element (373f) or a collimator (373e) may be disposed in another structure such as an opening (377e) of the first casing (377). In embodiments, an optical element such as a diffractive optical element (373f) or a collimator (373e) may be disposed in a light emitting element assembly (373) (e.g., a second casing (373c)) as a component that aligns or focuses light (e.g., radiated light (EL)) emitted from a light emitting element (373d), thereby facilitating setting of the direction of propagation of the radiated light (EL).

[0100] According to embodiments, as optical elements for aligning the output light, a diffractive optical element and a collimator are exemplified, but embodiments of the present disclosure are not limited thereto, and the type or number of optical elements may be implemented differently from the exemplified embodiment depending on the specifications required for the optical module (307). For example, the diffractive optical element and the collimator may be replaced with an optical element such as a meta-lens, or additional optical elements not mentioned may be selectively combined. In embodiments, when including a diffractive optical element and / or a collimator, during the process of assembling the light emitting element assembly (373), the optical elements may be aligned and / or fixed at a designated position with respect to the light emitting element (373d) in accordance with the design specifications.

[0101] In embodiments, as mentioned above, the light receiving element (375) may include a first detection area (375a) configured to receive externally incident light, and a second detection area (375b) provided on one side (e.g., adjacent to one side) of the first detection area (375a). The light received by the first detection area (375a) may be, for example, first light (RL1) reflected by the subject after being emitted by the light emitting element assembly (373). In embodiments, the second detection area (375b) may detect at least a portion of light reflected or refracted within the second casing (373c) among the light emitted by the light emitting element (373d). For example, most of the light output by the light emitting element (373d) at a given point in time is reflected by the subject and detected by the first detection area (375a), and some of the light output by the light emitting element (373d) at a given point in time can travel through the interior of the first casing (377) and be detected by the second detection area (375b).

[0102] According to embodiments, the optical module (307) and / or the electronic device may calculate or determine the subject distance from the time from when light is emitted from the light emitting element assembly (373) to when the first detection area (375a) receives the first light (RL1). In embodiments, the time from when light is emitted from the light emitting element assembly (373) may be calculated or determined based on the time from when the second detection area (375b) receives the second light (RL2) under conditions of substantially performing an operation of detecting distance information. For example, the distance information may be calculated or determined based on the time from when the second light (RL2) reaches the second detection area (375b) to when the first light (RL1) reaches the first detection area (375a). In embodiments, when the amount of light (e.g., the amount of light of the first light (RL1) and / or the amount of light of the second light (RL2)) reaching the first detection area (375a) and / or the second detection area (375b) satisfies a specified size (e.g., 'TL' of FIG. 14 or 15), the point in time at which light is emitted from the light emitting element assembly (373) can be determined and / or the subject distance can be calculated or determined. In embodiments, the light emitting element assembly (373) may emit the first light (RL1) in the form of approximately 60,000 or more pulses toward the subject, and the point in time at which the first light (RL1) is received or the subject distance can be calculated or determined based on the point in time at which the largest number of pulses is received in the first detection area (375a). Such calculation or determination of the point in time or distance can suppress noise caused by interference from natural light or reflected light incident from an unintended direction.

[0103] According to embodiments, when a deviation occurs due to the operating environment (e.g., temperature), the deviation in the arrival time of the first light (RL1) may be substantially the same as the deviation in the arrival time of the second light (RL2). For example, even if there is a deviation due to the operating environment, when determining information about the distance based on the arrival times of the first light (RL1) and the second light (RL2), distortion of the distance information due to the operating environment can be suppressed. This will be discussed again with reference to FIGS. 14 and 15. For example, since a deviation in the operating environment, such as temperature, may occur due to the arrival time of the first light (RL1) and the arrival time of the second light (RL2) being substantially the same, when determining the distance to the subject based on the time difference between the arrival time of the first light (RL1) in the first detection area (375a) and the arrival time of the second light (RL2) in the second detection area (375b), deviation in distance measurement due to the operating environment can be suppressed.

[0104] According to embodiments, the first casing (377) may include a first receiving space (307a) for receiving a light-emitting element assembly (373), a second receiving space (307b) for receiving at least a portion of the first detection area (375a), and / or a guide structure (307c) disposed between the first receiving space (307a) and the second receiving space (307b). In embodiments, when the first detection area (375a) is disposed in the second receiving space (307b), at least a portion of the second detection area (375b) may be disposed inside the guide structure (307c). For example, the second receiving space (307b) and the guide structure (307c) may be provided as an area (or space) for receiving the light-receiving element (375). In embodiments, the light emitting element assembly (373) may be disposed in the first receiving space (307a) with the first guide hole (373g) aligned with the guide structure (307c). As a result, the first guide hole (373g) may function as a path for guiding the second light (RL2) from the inside of the second casing (373c) to the inside of the guide structure (307c). In embodiments, by being aligned with the first guide hole (373g), the guide structure (307c) may function as a structure for guiding or guiding the second light (RL2) to be incident on the second detection area (375b). In embodiments, the first casing (377) may be disposed on the first substrate (371) with the light emitting element assembly (373) and the light receiving element (375) disposed on the first substrate (371) by surface mounting technology.

[0105] According to embodiments, the first casing (377) may include a first partition wall (377c) disposed between the guide structure (307c) and the first receiving space (307a) and / or a second partition wall (377a) disposed between the guide structure (307c) and the second receiving space (307b). In embodiments, the first partition wall (377c) may be a portion of a structure that substantially guides the assembly position of the light emitting element assembly (373). For example, the first partition wall (377c) may extend from an inner surface of the first casing (377) toward the first substrate (371), and a portion of an outer surface of the light emitting element assembly (373) (e.g., the second casing (373c)) may be disposed to substantially face the first partition wall (377c). In embodiments, the second partition wall (377a) may be disposed to extend from the inner surface of the first casing (377) between the guide structure (307c) and the second receiving space (307b) and face the first substrate (371) and / or the light receiving element (375). In embodiments, the second partition wall (377a) may be disposed to correspond at least partially to the boundary between the first detection area (375a) and the second detection area (375b).

[0106] According to embodiments, the first partition wall (377c) may provide a second guide hole (377d) aligned with the first guide hole (373g). The second guide hole (377d) may be, for example, a hole at least partially surrounded by the first partition wall (377c) and the first substrate (371) and may provide a path for the second light (RL2) to enter the interior of the guide structure (307c). In embodiments, the second guide hole (377d) may provide a larger cross-sectional area or a larger space than the first guide hole (373g).

[0107] According to embodiments, the second partition wall (377a) may be disposed at least partially between the second receiving space (307b) and the guide structure (307c). For example, the second partition wall (377a) may allow the first light (RL1) reflected by the subject to be incident on the first detection area (375a) but may inhibit or block the light from being incident on the second detection area (375b). In embodiments, the second partition wall (377a) may inhibit or block the second light (RL2) guided to the second detection area (375b) through the guide structure (307c) from being incident on the first detection area (375a). In embodiments, the second partition wall (377a) may have a closed curve trajectory corresponding to the edge of the first detection area (375a). For example, the second bulkhead (377a) may be provided as a structure that divides or separates the space in which the first detection area (375a) is arranged from the remaining space inside the first casing (377).

[0108] According to embodiments, the optical module (307) may include a lens assembly (379) configured to focus or guide the first light (RL1) to the first detection area (375a). The lens assembly (379) may include, for example, at least one lens, and may guide the first light (RL1) reflected by the subject to the first detection area (375a). For example, a diffractive optical element (373f) or a collimator (373e) may be an optical system that focuses or guides light (e.g., radiated light (EL)) emitted from the light emitting element assembly (373) toward the subject, and the lens assembly (379) may be an optical system that guides light (e.g., first light (RL1)) reflected by the subject to the first detection area (375a).

[0109] According to embodiments, the light emitting element (373d), the diffractive optical element (373f), the collimator (373e), the lens assembly (379), and / or the light receiving element (375) (e.g., the first detection area (375a)) may be arranged or aligned to emit light (e.g., infrared laser light) toward a subject and receive light that is reflected by the subject after being emitted toward the subject. In embodiments, the light receiving element (375) may include a first detection area (375a) configured to receive first light (RL1) that is reflected by the subject after being emitted by the light emitting element assembly (373). In embodiments, the light receiving element (375) may include a second detection area (375b) configured to receive a second light (RL2) (e.g., the second light (RL2) of FIG. 13) that is part of the light emitted by the light emitting element (373d) and guided through a path within the optical module (307).

[0110] According to embodiments, the light emitting element (373d), the diffractive optical element, the collimator, the lens assembly (379), and / or the light receiving element (375) (e.g., the first detection area (375a)) may be assembled to the first substrate (371) within a specified error range. In embodiments, when the light emitting element (373d), the diffractive optical element (373f), the collimator (373e), the lens assembly (379), and / or the light receiving element (375) are individually assembled to the first substrate (371), if a defect occurs, a considerable amount of time may be required in the process of correcting the alignment state or error of the individual components, or the individual components may be damaged in the process of removing / replacing the individual components. In embodiments, during the process of manufacturing / assembling the light emitting element (373d), the diffractive optical element, and / or the collimator into the light emitting element assembly (373), defects or errors in the light emitting element assembly (373) can be confirmed / corrected, thereby facilitating improvement in the defect rate. In embodiments, when the light emitting element assembly (373) is already placed on the first substrate (371), defects or errors confirmed during the process of assembling the light receiving element (375) and / or the lens assembly (379) can be corrected during the process of assembling the light receiving element (375) and / or the lens assembly (379), thereby reducing the time and cost required for manufacturing / assembling the optical module (307) and facilitating improvement in the defect rate.

[0111] According to embodiments, the optical module (307) may include at least one reflective member (e.g., the reflective member (473) of FIG. 11 or 12) and / or an inclined surface (377f). For example, in providing a portion of the light output from the light emitting element (373d) to the second detection area (375b), the optical module (307) may use at least one reflective member (473) and / or an inclined surface (377f) to guide the second light (RL2) from the inside of the first receiving space (307a) (or the inside of the second casing (373c)) to the guide structure (307c) and / or to the second detection area (375b). In embodiments, when light is reflected by a structure such as an inner wall of the second casing (373c) or a collimator (373e), the optical module (307) can guide the reflected light to the guide structure (307c) and / or to the second detection area (375b) using at least one reflective member (473) and / or an inclined surface (377f). For example, by providing a portion of the output light as the second light (RL2) using at least one reflective member (473) and / or an inclined surface (377f), light loss due to reflection, refraction, and / or scattering within the optical module (307) can be suppressed. In embodiments, by including at least one reflective member (473) and / or an inclined surface (377f), the optical module (307) can have improved power efficiency and / or improved light efficiency.

[0112] In embodiments, the inclined surface (377f) may be provided as at least a portion of the inner surface of the first casing (377) on the guide structure (307c). In embodiments, the inclined surface (377f) may be subjected to a reflective surface treatment (e.g., plating, printing, or coating) to guide the second light (RL2) along a designated path. In embodiments, it may be understood that at least one reflective member (473) includes a reflective surface provided on the inclined surface (377f). In embodiments, the inclined surface (377f) may be provided between the second detection area (375b) and the first partition wall (377c) (e.g., the second guide hole (377d)). In embodiments, the inclined surface (377f) may refer to a surface inclined with respect to the first substrate (371) on the guide structure (307c) (e.g., the inner surface of the first casing (377). In embodiments, the distance from the first substrate (371) to the inclined surface (377f) at a position adjacent to the second guide hole (377d) may be greater than the distance from the first substrate (371) to the inclined surface (377f) at a position adjacent to the second detection area (375b). In embodiments, the inclined surface (377f) may be positioned so as not to substantially interfere with the second light (RL2) in the path along which the second light (RL2) travels from the first guide hole (373g) to the second detection area (375b).

[0113] In embodiments, at least one reflective member (473) may be provided on at least a portion of a structure facing the light-emitting element (373d) (e.g., an inner surface of the second casing (373c) or a collimator (373e)), an integrated circuit chip (373b), a second substrate (373a), a first partition wall (377c), and / or an inner surface of the guide structure (307c). For example, the at least one reflective member (473) may be understood as a configuration that sets a propagation path of the second light (RL2) from the light-emitting element (373d) to the second detection area (375b). The arrangement of the at least one reflective member (473) will be discussed again with reference to FIGS. 11 to 13.

[0114] Fig. 9 is a perspective view showing a light emitting element assembly (373) of an optical module (307) according to embodiments. Fig. 10 is a perspective view for explaining a state in which a light emitting element assembly (373) (e.g., a second casing (373c)) of an optical module (307) according to embodiments is placed in a first casing (377).

[0115] FIGS. 9 and 10 may illustrate, for example, a state in which a light-emitting element assembly (373) (e.g., a second casing (373c)) is disposed within a first casing (377) with a first guide hole (373g) aligned with a guide structure (307c). Referring to FIGS. 9 and 10 , the interior of the first casing (377) may include a first receiving space (307a) configured to receive the light-emitting element assembly (373) (e.g., a second casing (373c) may be provided within the first receiving space (307a), a second receiving space (307b) configured to receive a portion of a light-receiving element (375) (e.g., at least a portion of the first detection area (375a) of FIG. 7), and / or a guide structure (307c) disposed between the first receiving space (307a) and the second receiving space (307b). In embodiments, another portion of the light receiving element (375), for example, at least a portion of the second detection area (375b), may be disposed in the guide structure (307c).

[0116] According to embodiments, the first partition wall (377c) may be disposed between the first receiving space (307a) and the guide structure (307c), and may provide a second guide hole (377d) connecting the guide structure (307c) to the first receiving space (307a). When the first casing (377) is disposed on the first substrate (371) of FIG. 7, the second guide hole (377d) may be at least partially surrounded by the first substrate (371) and the first partition wall (377c). In embodiments, the second partition wall (377a) may be disposed between the guide structure (307c) and the second receiving space (307b). In embodiments, the second partition wall (377a) may have a shape disposed to form a closed curved trajectory. For example, the second partition wall (377a) may be provided in a closed curve shape or a polygonal ring shape corresponding to the edge of the first detection area (375a). For example, when the shape is arranged to form a closed curve trajectory, a part of the second partition wall (377a) may be arranged in the guide structure (307c) and the second receiving space (307b), and the second receiving space (307b) may be arranged at least partially between two different parts of the second partition wall (377a).

[0117] According to embodiments, as described above, the light output by the light emitting element (373d) inside the second casing (373c) is substantially radiated toward the subject, but a portion of the output light (e.g., the second light (RL2)) may be reflected or refracted by an internal structure (e.g., an optical element such as a collimator (373e) or an inner wall of the second casing (373c)) and provided to the second detection area (375b). In embodiments, when the second casing (373c) is arranged in the first receiving space (307a), the first guide hole (373g) may be aligned with the guide structure (307c). For example, the light emitting element assembly (373) may be arranged in the first receiving space (307a) at a position where the first guide hole (373g) and the second guide hole (377d) are aligned to face each other.

[0118] According to embodiments, the relative positions of the light-emitting element (373d) and the light-receiving element (375) (e.g., the second detection area (375b)) may be determined differently depending on the specifications of the optical module (307). In order to secure the amount of light of the second light (RL2) from the light-emitting element assembly (373) to the second detection area (375b), the sizes of the first guide hole (373g) and the second guide hole (377d) may be determined. In embodiments, when the second guide hole (377d) is implemented to be sufficiently larger than the first guide hole (373g), the degree of design freedom in the position or size of the first guide hole (373g) may be increased. For example, considering the relative positions of the light-emitting element (373d) and the light-receiving element (375) (e.g., the second detection area (375b)), and / or the amount of light of the second light (RL2) received in the second detection area (375b), the design of the size of the first guide hole (373g) or the position of the first guide hole (373g) in the D1 direction may be facilitated. In embodiments, the power of light reaching the second detection area (375b) may be higher in a structure in which the first guide hole (373g) is disposed closer to the light-receiving element (375) (e.g., the second detection area (375b)) compared to a state in which the first guide hole (373g) is disposed closer to the center of the light-emitting element (373d). For example, the size or position of the first guide hole (373g) can be determined by considering the amount of light of the second light (RL2) received in the second detection area (375b).

[0119] Fig. 11 is a plan view showing a portion of a light emitting element assembly (373) of an optical module (307) according to embodiments. Fig. 12 is a drawing for explaining a light emitting element assembly (373) of an optical module (307) according to embodiments. Fig. 13 is a drawing for explaining a path along which a reference light (e.g., a second light (RL2)) of an optical module (307) according to embodiments proceeds.

[0120] Referring to FIGS. 11 to 13, light output from a light-emitting element (373d) is generally radiated toward a subject, and a portion of the light output from the light-emitting element (373d) (e.g., second light (RL2)) may be reflected or refracted inside the optical module (307) and / or the light-emitting element assembly (373) and provided to the second detection area (375b) via the guide structure (307c). The point in time when the second light (RL2) is detected in the second detection area (375b) may serve as a basis for calculating or determining subject distance information, together with the point in time when the first light (RL1) is reflected by the subject and detected in the first detection area (375a), for example. In embodiments, a deviation may occur in distance information for a subject at the same distance depending on the operating environment (e.g., temperature). For example, distance information based solely on the time at which the first light (RL1) is detected may contain deviations depending on the operating environment, and the time at which the second light (RL2) is detected may be used to compensate for these deviations. Compensation for these deviations depending on the operating environment will be further discussed with reference to FIGS. 14 and 15.

[0121] According to embodiments, the optical module (307) may include at least one reflective member (473) to guide or direct light reflected or refracted within the optical module (307) to the second detection area (375b). For example, the at least one reflective member (473) may increase the amount or power of light (e.g., second light (RL2)) reaching the first guide hole (373g) and / or the second detection area (375b) compared to a structure in which the reflective member is not arranged. The at least one reflective member (473) may be arranged on, for example, an integrated circuit chip (373b) or a second substrate (373a), but may be sufficiently insulated so as not to affect electrical operation. In embodiments, at least one reflective member (473) may be provided on at least a portion of the collimator (373e), the inner wall of the second casing (373c), and / or the inner wall of the second guide hole (377d). The at least one reflective member (473) may include a plating layer, a printing layer, and / or a coating layer provided on the inner surface (e.g., the inclined surface (377f)) of the first casing (377) on the guide structure (307c). For example, by providing at least one reflective member (473) inside the optical module (307), a structure that guides or guides light that is not emitted toward the subject to the second detection area (375b) may be implemented.

[0122] According to embodiments, when the light emitting element (373d) is a vertical cavity surface emitting laser including multiple channels, the amount of light reaching the second detection area (375b) may vary depending on the relative position of each channel. In embodiments, considering the ratio of light reaching the second detection area (375b) among the light emitted from each channel, the size and position of the first guide hole (373g), the size and position of the second guide hole (377d), and / or the size and position of at least one reflective member (473) may be selected. For example, by using the size and position of the first guide hole (373g), the size and position of the second guide hole (377d), and / or the size and position of at least one reflective member (473), the deviation of distance information depending on the operating environment can be further suppressed. As the accuracy of the distance information increases, the quality of the subject image or the accuracy in user authentication can increase.

[0123] Fig. 14 is a graph illustrating a first measurement result of an optical module (307) according to embodiments. Fig. 15 is a graph illustrating a second measurement result of an optical module (307) according to embodiments.

[0124] FIGS. 14 and 15 are graphs that measure the time from the time light is emitted toward a subject at the same distance to the time light reflected by the subject is received, wherein the horizontal axis represents the time at which light is emitted and / or the time at which light is received by the light receiving element (375), and the vertical axis may represent the amount of light received. The 'TL' exemplified on the vertical axis may exemplify a threshold value for determining that the amount of light received is valid. For example, the optical module (307), the electronic device (e.g., the electronic devices (1001, 1002, 1004, 100, 200) of FIGS. 1 to 5), and / or at least one processor (e.g., the processor (1020) of FIG. 1) may utilize the time at which the amount of light is received as the basis for calculating or determining distance information when the amount of light greater than or equal to 'TL' is received. In embodiments, a light source (e.g., a light emitting element assembly (373)) may emit a plurality of pulses (e.g., approximately 60,000 pulses), and distance information may be determined based on the point in time when the largest number of pulses are reflected by a subject and received by a light receiving element (375) among the emitted pulses.

[0125] FIG. 14 may illustrate a first reference time point (TR1) at which a portion of light (e.g., the second light (RL2) of FIG. 13) emitted from a light-emitting element assembly (373) is received in a second detection area (375b) and a first detection time point (TD1) at which the first light (RL1) emitted from the light-emitting element assembly (373) and then reflected by the subject is received in a first detection area (375a) when detecting distance information of a subject at a designated location for, for example, an optical module (307) or an electronic device (e.g., the electronic devices 1001, 1002, 1004, 100, 200 of FIGS. 1 to 5). In embodiments, the distance measurement of FIG. 14 may be understood to have been performed at room temperature. The subject distance at a specified location at room temperature can be calculated or determined based on the time taken from the first reference time point (TR1) to the first detection time point (TD1). For example, the subject distance information can be calculated based on the first detection time point (TD1) without considering the first reference time point (TR1), but the optical module (307), the electronic device (200), and / or at least one processor (1020) according to the embodiment(s) of the present disclosure can determine the subject distance information by considering both the first reference time point (TR1) and the first detection time point (TD1).

[0126] FIG. 15 may illustrate a second reference time point (TR2) at which a portion of the light emitted from the light emitting element assembly (373) (e.g., the second light (RL2) of FIG. 13) is received in the second detection area (375b) and a second detection time point (TD2) at which the first light (RL1) emitted from the light emitting element assembly (373) and then reflected by the subject is received in the first detection area (375a), for example, in detecting distance information of a subject at substantially the same distance as the measurement in FIG. 14. In embodiments, the distance measurement in FIG. 15 may be understood to have been performed in a state where the light emitting element assembly (373) is raised to a temperature higher than room temperature (by approximately 10 degrees) through repeated photographing and / or repeated distance measurement. The distance to the subject at a high temperature (e.g., a temperature state approximately 10 degrees higher than room temperature) can be determined based on the time taken from the second reference time point (TR2) to the second detection time point (TD2). For example, the subject distance information can be calculated or determined based on the second detection time point (TD2) without considering the second reference time point (TR2). However, in this case, even if light that has traveled the same distance is received, the time point may be different from the time point received at room temperature due to the difference in the operating environment (e.g., temperature). This time point deviation due to the operating environment may correspond to the reception deviation (TC). For example, when the light emitting element assembly (373) operates at a temperature approximately 10 degrees higher than room temperature, there may be a deviation equal to the difference between the first reference time point (TR1) and the second reference time point (TR2). According to embodiments, the optical module (307), the electronic device (e.g., the electronic device (1001, 1002, 1004, 100, 200) of FIGS. 1 to 5), and / or at least one processor (e.g., the processor (1020) of FIG. 1) can suppress deviation in distance measurement depending on the operating environment by determining the subject distance by considering the second reference time point (TR2) and the second detection time point (TD2) together.

[0127] According to embodiments, the distance to the subject can be calculated or determined based on the difference between the first reference time point (TR1) and the first detection time point (TD1) of FIG. 14. For example, the time value according to the difference between the first reference time point (TR1) and the first detection time point (TD1) and the speed of the light emitted from the light emitting element assembly (373) can be variables used to determine the distance to the subject. In embodiments, the distance to the subject can be calculated or determined based on the difference between the second reference time point (TR2) and the second detection time point (TD2) of FIG. 15. For example, since the deviation according to temperature change can occur substantially equally at the second reference time point (TR2) and the second detection time point (TD2) compared to the time points (TD1, TR1) of FIG. 14, the time variable for determining the distance to the subject can be determined by directly comparing the second reference time point (TR2) and the second detection time point (TD2). In embodiments, the reception deviation (TC) according to the operating environment may be stored in the memory as data in the form of a table, and the reception deviation (TC) may be compared with the information stored in the memory based on a detected reference time point (e.g., the first reference time point (TR1) of FIG. 14 or the second reference time point (TR2) of FIG. 15) when measuring the distance to the subject, and a time variable for determining the distance to the subject may be determined or determined based on the difference between the detection time point (e.g., the first detection time point (TD1) of FIG. 14 or the second detection time point (TD2) of FIG. 15) and the reception deviation (TC). A method for measuring (or determining) the reception deviation (TC) and / or the distance information to the subject will be further described with reference to FIGS. 16 and 17.

[0128] Fig. 16 is a flowchart illustrating a method for measuring a reception deviation in an optical module (e.g., the optical module (307) of Figs. 6 to 8) according to embodiments. Fig. 17 is a flowchart illustrating a method for measuring subject distance information using an optical module (e.g., the optical module (307) of Figs. 6 to 8) according to embodiments.

[0129] According to embodiments, after the reception deviation (TC) according to temperature is measured in advance by the measuring method (500) of FIG. 16, the measured information can be stored in a memory (e.g., the memory (1030) of FIG. 1). At a point in time when a distance is to be measured, the reception deviation (TC) corresponding to the point in time when light is received in the second detection area (375b) by the measuring method (600) of FIG. 17 can be confirmed based on the data stored in the memory.

[0130] Referring to FIG. 16, a method (500) for measuring a reception deviation (TC) may include an operation (501) of measuring a reception deviation (TC) and an operation (502) of storing the measured reception deviation (TC). The operation 501 of measuring the reception deviation (TC) may be, for example, an operation of measuring a point in time when light emitted from a light-emitting element assembly (373) passes through the interior of an optical module (307) and reaches a second detection area (375b). The operation 502 of storing the measured reception deviation (TC) may be, for example, an operation of storing data in a memory in the form of a table matching a current measurement temperature with a corresponding reference point in time. For example, the method (500) for measuring the reception deviation (TC) may be performed or completed by determining a reference point measured at a specified temperature (e.g., room temperature of approximately 20 degrees) as a first reference point (TR1), repeatedly measuring the reference point (e.g., the second reference point (TR2) of FIG. 15) while changing the temperature of the surrounding environment, and / or storing the reception deviation (TC) according to the temperature at the time of measurement (e.g., the time difference between the first reference point (TR1) and the second reference point (TR2)) in the form of tabulated data in a memory.

[0131] Referring to FIG. 17, the method (600) for measuring subject distance information may include an operation (601) for measuring a distance, an operation (602) for compensating for a deviation, an operation (603) for determining a distance, and / or an operation (604) for acquiring an image. In embodiments, when the electronic device (100, 200) of FIGS. 2 to 5 acquires a subject image, the distance information determined by the method (600) for measuring subject distance information may be used for processing or post-processing of the acquired image.

[0132] According to embodiments, in operation 601, the electronic device (100, 200) and / or the optical module (307) may emit light using the light emitting element assembly (373). In embodiments, a portion of the light emitted from the light emitting element assembly (373) may be reflected by the subject and reach the first detection area (375a), and another portion of the light emitted from the light emitting element assembly (373) may travel through the interior of the optical module (307) and reach the second detection area (375b). In embodiments, even if the distance from the electronic device (100, 200) and / or the optical module (307) to the subject is the same, a deviation may occur in the distance measurement value depending on the temperature at the time of measuring the distance information.

[0133] According to embodiments, in operation 602, the electronic device (100, 200) and / or the optical module (307) determines a reception deviation (TC) corresponding to the time point (e.g., the second reference time point (TR2)) when light reaches the second detection area (375b) or based on the amount of light, and excludes the reception deviation (TC) determined at the time point (e.g., the second detection time point (TD2)) when light reaches the first detection area (375a), thereby compensating for the deviation of the measurement value due to the temperature difference. In embodiments, operation 603 may be an operation of determining the measurement value with the deviation compensated as the distance to the subject. As described above, when the distance measuring method (600) of FIG. 17 is performed when capturing an image of a subject, the determined distance (e.g., the distance to the subject) can be used to improve the quality of the acquired image. For example, the distance measuring method (600) of FIG. 17 may be performed while capturing an image of a subject, and the distance information to the subject measured (or determined) in operation 603 may be used as one of the information(s) that form the basis of the image acquired in operation 604.

[0134] FIG. 18 is a perspective view illustrating the internal configuration of a wearable electronic device (700) according to embodiments.

[0135] According to embodiments of the present disclosure, the wearable electronic device (700) of FIG. 18 (or the wearable electronic device (800) of FIGS. 19 and 20 described below) may be substantially the same as the electronic device (1001) of FIG. 1 and may be implemented to be wearable on a user's body. In embodiments, each of the external electronic devices (1002, 1004) of FIG. 1 may be the same or a different type of device as the electronic device (1001) or the wearable electronic device (700, 800). According to embodiments, all or part of the operations executed in the electronic device (1001) or the wearable electronic device (700, 800) may be executed in one or more of the external electronic devices (1002, 1004, or 1008). For example, when an electronic device (1001) or a wearable electronic device (700, 800) needs to perform a function or service automatically or in response to a request from a user or another device, the electronic device (1001) or the wearable electronic device (700, 800) may, instead of or in addition to executing the function or service on its own, request one or more external electronic devices to execute at least a part of the function or service. The one or more external electronic devices that receive the request may execute at least a part of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (1001) or the wearable electronic device (700, 800). The electronic device (1001) or the wearable electronic device (700, 800) may process the result as is or additionally and provide it as at least a part of a response to the request.For example, an external electronic device (1002) renders content data executed in an application and transmits it to an electronic device (1001) or a wearable electronic device (700, 800), and the electronic device (1001) or the wearable electronic device (700, 800) that receives the data can output the content data to a display module (e.g., the display module (1060), the light output module (711), the display (821) of FIG. 1). When the electronic device (1001) or the wearable electronic device (700, 800) detects user movement through an inertial measurement unit sensor or the like, the processor (e.g., the processor (1020) of the electronic device (1001) or the wearable electronic device (700, 800) can correct the rendering data received from the external electronic device (1002) based on the movement information and output the corrected data to the display module. Alternatively, the motion information may be transmitted to an external electronic device (1002) to request rendering so that screen data is updated accordingly. According to embodiments, the external electronic device (1002) may be a variety of devices, such as a case device capable of storing and charging the electronic device (1001).

[0136] Referring to FIG. 18, a wearable electronic device (700) according to embodiments may include at least one of a light output module (711), a display member (701), and a camera module (750). According to embodiments, the light output module (711) may include a light source capable of outputting an image (e.g., a projector or a display panel (911a) of FIG. 21), and a lens (e.g., a lens (911b) of FIG. 21) that guides the image to the display member (701). According to one embodiment of the present disclosure, the light output module (711) may include at least one of a liquid crystal display (LCD), a digital mirror device (DMD), a liquid crystal on silicon (LCoS), an organic light emitting diode (OLED), or a micro light emitting diode (micro LED).

[0137] According to embodiments, the display member (701) may include a light waveguide (e.g., the light waveguide (913a) of FIG. 21). According to embodiments, an image output from the light output module (711) incident on one end of the light waveguide may be propagated within the light waveguide and provided to a user. For example, the display member (701) may be an optical system that guides or focuses an image output from the light output module (711) along a designated path (e.g., the first path (P1) of FIG. 21) to the user's naked eye.

[0138] According to embodiments, the display member (701) may include at least one of a diffractive optical element (DOE), a holographic optical element (HOE), or a reflective element (e.g., a reflective mirror) provided in the optical waveguide (e.g., the couplers (913b, 913c)(s) of FIG. 21). For example, the display member (701) may guide an output image of the optical output module (711) to a user's eye by including at least one diffractive optical element, a holographic optical element, or a reflective element, and / or by including an optical waveguide.

[0139] According to embodiments, the camera module (750) can capture still images and / or moving images. According to embodiments, the camera module (750) can be disposed within a lens frame and can be disposed around the display member (701). In embodiments, the wearable electronic device (700) can obtain information about the distance to the subject by including the optical module (307) of FIGS. 6 to 8 when capturing still images and / or moving images using the camera module (750).

[0140] According to embodiments, the first camera module (751) can capture and / or recognize the trajectory of the user's eye (e.g., pupil, iris) or gaze. According to embodiments of the present disclosure, the first camera module (751) can periodically or aperiodically transmit information related to the trajectory of the user's eye or gaze (e.g., trajectory information) to a processor (e.g., processor (1020) of FIG. 1).

[0141] According to embodiments, the second camera module (753) can capture external images.

[0142] According to embodiments, the third camera module (755) may be used for hand detection and tracking, and user gesture (e.g., hand movement) recognition. According to embodiments, the third camera module (755) may be used for 3 degrees of freedom (3DoF), 6DoF head tracking, location (spatial, environmental) recognition, and / or movement recognition. According to embodiments, the second camera module (753) may also be used for hand detection and tracking, and user gesture recognition. According to embodiments, at least one of the first camera module (751) to the third camera module (755) may be replaced with a sensor module (e.g., a LiDAR sensor). For example, the sensor module may include at least one of a vertical cavity surface emitting laser (VCSEL), an infrared sensor, and / or a photodiode. In embodiments, the sensor module may be implemented by the optical module (307) of FIGS. 6 to 8.

[0143] According to embodiments, a wearable electronic device (700) may include a pair of display elements (701) arranged parallel to one side of each other. For example, a user may wear the wearable electronic device (700) on the face, and the display elements (701) may be arranged to correspond to any one of the user's eyes while the wearable electronic device (700) is worn on the user's face. In embodiments, when including a pair of display elements (701), the wearable electronic device (700) may provide visual information to the user through any one of the display elements (701) and / or through each display element (701).

[0144] According to embodiments, the wearable electronic device (700) may include at least one wearing member (702a, 702b) extending from or rotatably coupled to the display member (701). In embodiments, the wearing member (702a, 702b) may be exemplified as a structure that is rotatably coupled (or connected) to the display member (701) by a hinge structure (H). For example, the wearing member (702a, 702b) may be in a position overlapped or folded with the display member (701), in which case the user may easily carry or store the wearable electronic device (700). In embodiments, the wearable electronic device (700) can be easily worn on the user's face at a position where the wearing member (702a, 702b) is rotated by a specified angle (e.g., approximately 90 degrees) from a position overlapping the display member (701). For example, the wearable electronic device (700) can be stably worn by supporting the display member (701) on the user's face and supporting the wearing member (702a, 702b) on the side of the user's head (e.g., the ear).

[0145] FIG. 19 and FIG. 20 are drawings showing the front and back of a wearable electronic device (800) according to embodiments.

[0146] Referring to FIGS. 19 and 20, in embodiments, camera modules (811, 812, 813, 814, 815, 816) and / or depth sensors (817) for obtaining information related to the surrounding environment of the wearable electronic device (800) may be arranged on the first surface (810) of the housing.

[0147] In embodiments, the camera modules (811, 812) can acquire images related to the environment surrounding the wearable electronic device (800).

[0148] In embodiments, the camera modules (813, 814, 815, 816) can acquire images while the wearable electronic device (800) is worn by the user. In embodiments, the wearable electronic device (800) includes the optical module (307) of FIGS. 6 to 8, so that when acquiring images using the camera modules (813, 814, 815, 816), information about the distance to the subject can be acquired. The camera modules (813, 814, 815, 816) can be used for hand detection, tracking, and recognition of user gestures (e.g., hand movements). The camera modules (813, 814, 815, 816) can be used for 3DoF, 6DoF head tracking, position (spatial, environmental) recognition, and / or movement recognition. In embodiments, camera modules (811, 812) may be used for hand detection and tracking, and user gestures.

[0149] In embodiments, the depth sensor (817) may be configured to transmit a signal and receive a signal reflected from a subject, and may be used for purposes such as time of flight (TOF) to determine the distance to an object. Instead of or in addition to the depth sensor (817), camera modules (813, 814, 815, 816) may determine the distance to an object. In embodiments, the depth sensor (817) may be implemented by the optical module (307) of FIGS. 6 to 8.

[0150] According to embodiments, a camera module (825, 826) for facial recognition and / or a display (821) (and / or a lens) may be arranged on the second side (820) of the housing.

[0151] In embodiments, a face recognition camera module (825, 826) adjacent to the display (821) may be used to recognize a user's face, or may recognize and / or track both eyes of the user.

[0152] In embodiments, the display (821) (and / or lens) may be disposed on the second side (820) of the wearable electronic device (800). In embodiments, the wearable electronic device (800) may not include the camera module(s) indicated as '815' and / or '816' among the plurality of camera modules (813, 814, 815, 816). The wearable electronic device (800) may further include at least one of the configurations illustrated in FIG. 18.

[0153] As described above, the wearable electronic device (800) according to the embodiments may have a form factor for being worn on a user's head. The wearable electronic device (800) may further include a strap for being fixed on a body part of the user, and / or a wearing member (e.g., the wearing member (702a, 702b) of FIG. 18). The wearable electronic device (800) may provide a user experience based on augmented reality, virtual reality, and / or mixed reality while being worn on the user's head.

[0154] FIG. 21 is a drawing showing a portion of a wearable electronic device (e.g., the electronic device (1001) of FIG. 1 and / or the wearable electronic devices (700, 800) of FIGS. 18 to 20) according to embodiments.

[0155] Referring to FIG. 21, the wearable electronic device may include a light output module (911) (e.g., the light output module (711) of FIG. 18), a display member (901) (e.g., the display member (701) of FIG. 18), a first polarizing reflector (961), a polarizing modulator (963), and / or a second polarizing reflector (965). The display member (901) may be, for example, a see-through optical element that transmits light or an image about an environment or an object (O) around the user and provides the light or image to the user along a designated path (e.g., a second path (P2)). In embodiments, the display member (901) may be a see-through optical element and provide a first path (P1) that guides or directs light (e.g., visual information such as characters or images) output from the light output module (911) to the user's naked eye (E). For example, a wearable electronic device can provide an environment in which a user can visually recognize a surrounding space or object (O) by including a transparent optical element (e.g., a display member (901)), and can visually provide stored or received information to the user by using a light output module (911) and a display member (901).

[0156] According to embodiments, when visually providing various information to a user, a portion of the light output by the light output module (911) may leak into the external space. In embodiments, the first polarizing reflector (961), the polarizing modulator (963), and / or the second polarizing reflector (965) may reflect at least a portion of the light leaking into the external space and provide it to the user, and / or absorb a portion of the light leaking into the external space. In embodiments, when the first polarizing reflector (961), the polarizing modulator (963), and / or the second polarizing reflector (965) reflects the light leaking into the external space, the wearable electronic device may provide visual information to the user more clearly or more brightly. For example, the wearable electronic device may have improved light efficiency or improved power efficiency.

[0157] According to embodiments, the light output module (911) may include a display panel (911a) that outputs light (e.g., visual information such as an image) and at least one lens (911b). The display panel (911a) may include, for example, the above-described liquid crystal display, digital mirror display, silicon liquid crystal display, organic light emitting diode, or micro LED. In embodiments, the lens (911b) may guide or focus light output from the display panel (911a) to the display member (901). In embodiments, in guiding or aligning the light to the display member (901), the light output module (911) may further include a reflective member (e.g., a mirror) or a refractive member (e.g., a prism). For example, depending on the direction in which the display panel (911a) is aligned, the light output module (911) may further include a reflective member or a refractive member to output light in a direction toward the display member (901).

[0158] According to embodiments, the display member (901) may include a first surface (F1) and a second surface (F2) opposite to the first surface (F1). In embodiments, when the wearable electronic device is worn on a user's face, the first surface (F1) may be arranged to substantially face the user's face or the user's eyes, and the second surface (F2) may be arranged to face an external space (e.g., an environment around the user). In embodiments, an image of the surrounding environment or an object (O) may be provided to the user by being incident on the second surface (F2) along a second path (P2) and output through the first surface (F1). For example, the display member (901) may transmit at least a portion of light incident on the second surface (F2) to the first surface (F1). In embodiments, light output from the light output module (911) may be provided to a user by traveling through the interior of the display member (901) along the first path (P1) and being output through the first surface (F1). For example, the display member (901) may guide light output from the light output module (911) to the user's eyes.

[0159] According to embodiments, the display member (901) may include an optical waveguide (913a) and couplers (913b, 913c), thereby providing light output from the optical output module (911) to a user. Among the couplers (913b, 913c), a first coupler (913b) may be provided at one end of the optical waveguide (913a) and aligned with the optical output module (911). For example, light guided or focused by a lens (911b) may be input into the optical waveguide (913a) through the first coupler (913b). Among the couplers (913b, 913c), a second coupler (913c) may be provided at the other end of the optical waveguide (913a). In embodiments, when the wearable electronic device is worn on the user's face, the second coupler (913c) may be substantially aligned with the user's eyes. For example, light guided or focused by the lens (911b) may be input into the optical waveguide (913a) through the first coupler (913b) and may travel along the optical waveguide (913a), and the light traveling along the optical waveguide (913a) may be provided to the user's eyes by the second coupler (913c).

[0160] According to embodiments, the first coupler (913b) and / or the second coupler (913c) may include at least one of a diffractive optical element, a holographic optical element, and / or a reflective element. For example, light output from the light output module (911) may be input to the optical waveguide (913a) by the first coupler (913b), and light propagating through the optical waveguide (913a) may be output to the first surface (F1) by the second coupler (913c). At a point in time when the propagation direction of the light is controlled by the first coupler (913b) and / or the second coupler (913c), and / or at a point in time when the light propagating through the optical waveguide (913a) is reflected within the optical waveguide (913a), a portion of the light may leak out to the outside. A wearable electronic device according to an embodiment(s) of the present disclosure can suppress light output from a light output module (911) from leaking to the outside by including a first polarizing reflector (961), a polarizing modulator (963), and / or a second polarizing reflector (965).

[0161] In the embodiments, the first polarizing reflector (961), the polarizing modulator (963), and / or the second polarizing reflector (965) are illustrated as being arranged at a position corresponding to the second coupler (913c), but when there is a part in which the light output from the light output module (911) may leak out of the path along the display member (901), the first polarizing reflector (961), the polarizing modulator (963), and / or the second polarizing reflector (965) may be further extended or additionally arranged at an appropriate position. For example, the first polarizing reflector (961), the polarizing modulator (963), and / or the second polarizing reflector (965) may be extended or additionally arranged at a position corresponding to the first coupler (913b) or the optical waveguide (913a). In embodiments, the first polarizing reflector (961), the polarizing modulator (963), and / or the second polarizing reflector (965) may be disposed substantially over the entire area of ​​the second surface (F2). In embodiments, when the structure sufficiently suppresses leakage of light traveling along the first path (P1), the first polarizing reflector (961), the polarizing modulator (963), and / or the second polarizing reflector (965) may be omitted in the wearable electronic device.

[0162] According to embodiments, the first polarizing reflector (961) may be disposed on one surface (e.g., the second surface (F2)) of the display member (901) and configured to reflect or absorb at least a portion of light leaking to the outside via the second coupler (913c). For example, when visual information to be provided to the user is provided to the user, a portion of the light output from the light output module (911) may be output to the second surface (F2) via the second coupler (913c). The first polarizing reflector (961) may increase the light efficiency of the wearable electronic device by reflecting the light output to the second surface (F2) via the second coupler (913c) to the first surface (F1).

[0163] According to embodiments, when the first polarizing reflector (961) is configured to reflect light of a first polarization component (e.g., horizontal linear polarization (p-pol)), light of a second polarization component different from the first polarization component (e.g., vertical linear polarization (s-pol)) may be transmitted through the first polarizing reflector (961). In embodiments, similar to the first polarizing reflector (961), the second polarizing reflector (965) may be configured to reflect light of the first polarization component, and the polarization modulator (963) may modulate at least a portion of the light transmitted through the first polarizing reflector (961) into light of the first polarization component and transmit the modulated light to the second polarizing reflector (965). For simplicity of explanation, in the embodiments, light of the first polarization component may be referred to as horizontal linear polarization, and light of the second polarization component may be referred to as vertical linear polarization. However, it should be noted that the embodiments of the present disclosure are not limited thereto. In the embodiments, when light of a third polarization component, such as circular polarization or elliptically polarized light, is incident on the first polarization reflector (961) (or the second polarization reflector (965)), some of the light of the third polarization component may transmit through the first polarization reflector (961) (or the second polarization reflector (965)), and at least some of the remaining light of the third polarization component may be reflected by the first polarization reflector (961) (or the second polarization reflector (965)).

[0164] According to embodiments, the polarization modulator (963) may be disposed on the first polarization reflector (961). For example, the polarization modulator (963) may be disposed substantially facing the second surface (F2) with the first polarization reflector (961) therebetween. In embodiments, the polarization modulator (963) may be disposed between the first polarization reflector (961) and the second polarization reflector (965) to modulate a polarization component of at least a portion of the light transmitted through the first polarization reflector (961). For example, the polarization modulator (963) may modulate at least a portion of the light transmitted through the first polarization reflector (961) into light having a polarization component reflected by the second polarization reflector (965). In embodiments, the polarization modulator (963) can substantially transmit light transmitted through the first polarizing reflector (961) while modulating at least a portion of the polarization component of the light transmitted through the polarization modulator (963). In embodiments, the polarization modulator (963) can include a wave plate (963a) (e.g., a half-wave phase retarder) and a rotator (963b) (e.g., a Faraday rotator). In embodiments, the wave plate (963a) can change the polarization direction of light passing through the polarization modulator (963) by a specified angle, and the rotator (963b) can modulate the polarization axis of light passing through the polarization modulator (963) in a specified direction. Depending on the specifications of the wearable electronic device (700, 800) or the display member (901), the optical elements included in the polarization modulator (963) (e.g., phase retarder (963a) and / or rotator (963b)) may be implemented differently from those illustrated.

[0165] According to embodiments, the second polarizing reflector (965) may be disposed on the polarization modulator (963). For example, the second polarizing reflector (965) may be disposed substantially facing the second surface (F2) with the first polarizing reflector (961) and the polarization modulator (963) interposed therebetween. In embodiments, the second polarizing reflector (965) may reflect at least a portion of the light transmitted through the polarization modulator (963) and guide the light to the second surface (F2) and / or the first surface (F1). For example, the second polarizing reflector (965) may reflect light of the first polarization component, and at least a portion of the light transmitted through the polarization modulator (963) may be light of the first polarization component.

[0166] According to embodiments, when including the optical module (307) of FIGS. 6 to 8, the wearable electronic device (700, 800) can detect (or determine) information regarding the distance to the subject when acquiring an image of the subject. For example, by including subject distance information when processing an image provided to the user, the wearable electronic device (700, 800) can provide the user with an image of improved quality.

[0167] As described above, the optical module according to the embodiments (e.g., the optical module (307) of FIGS. 6 to 8) and / or the electronic device including the same (e.g., the electronic device (1001, 1002, 1004, 100, 200) of FIGS. 1 to 5) is provided with a structure in which a light-emitting element assembly (e.g., the light-emitting element assembly (373) of FIG. 7) including a light-emitting element (e.g., the light-emitting element (373d) of FIG. 7) and / or a driving circuit thereof (e.g., the integrated circuit chip (373b) of FIG. 7) is disposed on a substrate (e.g., the first substrate (371) of FIG. 7) on which a light-receiving element (e.g., the light-receiving element (375) of FIG. 7) is disposed) is disposed through a surface mounting technique, thereby suppressing damage to components that may occur during the manufacturing process or in the correction of defects. In embodiments, the substrate of the light-emitting element assembly (e.g., the second substrate (373a) on which the light-emitting element and / or its driving circuit are disposed in FIG. 7) and / or the substrate of the optical module on which such substrate is disposed (e.g., the first substrate (371) on which the light-emitting element assembly and / or the light-receiving element are disposed in FIG. 7) may include a ceramic material such as LTCC or HTCC, thereby quickly dissipating or releasing heat generated during the operation of the light-emitting element. For example, the deterioration of the operating environment of the light-emitting element or electronic device due to heat generation may be suppressed. In embodiments, the optical module may guide or direct light reflected or refracted within it to the light-receiving element (e.g., the second detection area (375b) in FIG. 7) to be used for distance measurement. For example, the optical efficiency and / or power efficiency of the optical module may be improved, and the accuracy of distance measurement may be increased. In embodiments, by appropriately designing (or manufacturing) the shape of the internal space of the light-emitting element assembly or the size of the internal space of the first casing (377), the amount of light (e.g., the second light (RL2)) guided to the first guide hole (373g) or the second detection area (375b) can be sufficiently secured.When the amount of light (e.g., second light (RL2)) guided to the first guide hole (373g) or the second detection area (375b) is sufficiently secured, deviation in subject distance measurement due to changes in the operating environment (e.g., temperature) can be suppressed.
