Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The following is combined Figures 1 to 7 This application describes the optical communication system.

[0037] According to the embodiments of the first aspect of this application, such as Figure 1 , Figure 4 and Figure 5 The optical communication system includes at least two optical communication devices 1. One of the at least two optical communication devices 1 is provided with a laser emitting component 3, and the other of the at least two optical communication devices 1 is provided with a spectral chip 4. The laser emitting component 3 is used to emit laser light to the spectral chip 4, and the spectral chip 4 receives the laser light emitted by the laser emitting component 3 to establish a communication connection between the at least two optical communication devices 1.

[0038] Control methods for optical communication systems include:

[0039] Step 101: Determine the target's luminous shape based on the target information;

[0040] Step 102: Based on the target emission shape, control the laser emitting component 3 to emit laser light into the spectral chip 4;

[0041] And / or,

[0042] Step 201: Determine the target laser arrangement order based on the target information. The laser emitting component 3 is used to emit at least two laser beams to the spectral chip 4. The optical parameters of the different lasers are different.

[0043] Step 202: Based on the target laser arrangement order, control the laser emitting component 3 to emit lasers to the spectral chip 4.

[0044] According to the control method of the optical communication system in this application embodiment, the target emission shape can be determined according to the target information to be transmitted, that is, the target emission shape is used to represent the target information and the emission shape is used to encode the target information. Then, according to the target emission shape, the laser emitting component 3 is controlled to emit laser to the spectral chip 4, so that the spectral chip 4 can receive the beam of the target emission shape. Subsequently, the target emission shape is decoded to obtain the target information, thereby realizing the transmission of target information and establishing a communication connection between two optical communication devices 1.

[0045] Furthermore, the laser arrangement order of different laser beams can be determined according to the target information to be transmitted. That is, the laser arrangement order is used to represent the target information and to encode the target information. Then, according to the target laser arrangement order, the laser emitting component 3 is controlled to emit lasers to the spectral chip 4, so that the spectral chip 4 can receive the combination of beams arranged in the target laser arrangement order. Subsequently, the target laser arrangement order is decoded to obtain the target information, thereby realizing the transmission of target information and establishing a communication connection between the two optical communication devices 1.

[0046] Target information can also be encoded using both the emission shape and the laser arrangement order, meaning the combination of emission shape and laser arrangement order represents the target information. Then, based on the target emission shape and laser arrangement order, the laser emitting component 3 is controlled to emit laser light to the spectral chip 4, allowing the spectral chip 4 to receive the beam combination of the target emission shape, where the multiple beams in the beam combination are arranged in the target laser arrangement order. Subsequent decoding of the target emission shape and laser arrangement order yields the target information, thus enabling the transmission of target information and establishing a communication connection between the two optical communication devices 1.

[0047] In other words, this application decodes target information by the shape of light emission and / or the laser arrangement order. Then, it controls the laser emitting component 3 to emit laser light to the spectral chip 4 according to the shape of light emission and / or the laser arrangement order. The spectral chip 4 processes the received beam to obtain the target's light emission shape information and / or target laser arrangement order information. Subsequent decoding of the target's light emission shape and / or target laser arrangement order yields the target information, thus enabling the transmission of target information and establishing a communication connection between two optical communication devices 1. Because lasers have strong anti-interference capabilities, they can effectively prevent the optical communication system from being interfered with or taken over. Furthermore, they are difficult to crack, resulting in higher security. Only interfering light sources within the field of view of the spectral chip 4 can interfere with it, further improving the anti-interference capability and security of the optical communication system.

[0048] It should be noted that when using the laser arrangement order to transmit target information, since different lasers have different optical parameters, these parameters can be used to distinguish different lasers and thus determine their arrangement order. For example, different lasers may have different wavelengths. For instance, if there are three lasers with different wavelengths: band a, band b, and band c, then abc and acb represent different arrangement orders. The spectral chip 4, upon receiving the laser, can determine the wavelength and thus the arrangement order. It is important to emphasize that this is only an example using wavelength; parameters such as light intensity and duration can also be used to distinguish different lasers, or two or more of these parameters can be used.

[0049] To facilitate understanding of the technical solution of this application, the following example illustrates how to transmit target information using the shape of light emission and the order of laser arrangement:

[0050] A single shape of light can represent an instruction or message, or a combination of two or more shapes of light can represent an instruction or message. For example, a triangle can represent "01" and a quadrilateral can represent "02". "01" can refer to an instruction alone, or "01" + "02" can refer to an instruction or message together.

[0051] The laser emitting component 3 sends at least two different laser beams to the spectral chip 4, assuming there are three different laser beams, labeled A, B, and C. There are a total of six possible arrangements of these three laser beams: ABC, ACB, BAC, BCA, CAB, and CBA. Each arrangement can represent a command or message, or a combination of two or more arrangements can represent a command or message. For example, ABC, ACB, BAC, BCA, CAB, and CBA can respectively represent "01", "02", "03", "04", "05", and "06".

[0052] Target information can also be transmitted using both the shape of the emitted light and the order of the laser arrangement. For example, a triangular shape with a laser arrangement of ABC represents "01"; a triangular shape with a laser arrangement of ACB represents "02"; a quadrilateral shape with a laser arrangement of ABC represents "10"; and a quadrilateral shape with a laser arrangement of ACB represents "20".

[0053] In some examples, the information represented by different emission shapes and / or different laser arrangement sequences can be pre-stored on the spectral chip 4 or the optical communication device 1 where the spectral chip 4 is located. When the spectral chip 4 receives laser combinations with different emission shapes and / or different laser arrangements, it can determine the specific information represented by the received laser combination and realize the decoding of the laser combination.

[0054] In one embodiment of this application, the laser emitting assembly 3 includes a plurality of laser emitters; the step of controlling the laser emitting assembly 3 to emit laser light to the spectral chip 4 based on the target emission shape includes:

[0055] Based on the target emission shape, the movement of the laser emitter is controlled so that the shape of the light emitted by the laser emission component 3 is the target emission shape.

[0056] It is understandable that when controlling the laser emitting component 3 to emit laser light to the spectral chip 4 according to the target emission shape, the movement of the laser emitter can be controlled first according to the target emission shape so that the beams emitted by multiple laser emitters can be combined to obtain the target emission shape, and then the laser emitting component 3 can be controlled to start working.

[0057] In some examples, the laser emitting assembly 3 includes multiple laser emitting units arranged in an array or a movable layout. Each laser emitter can independently control its physical position and emission angle. When a specific target emission shape needs to be formed, the spatial coordinates of each laser are adjusted by a precision mechanical drive system (such as a micro stepper motor, piezoelectric ceramic driver, or MEMS micromirror array), so that multiple laser beams are projected onto the receiving surface of the spectral chip 4 to form a predetermined geometric configuration.

[0058] Taking the formation of a triangular light spot as an example, the control system calculates the geometric parameters of the target shape (such as side length and vertex coordinates) into the target displacement of the three laser emitters. The first laser moves along the horizontal guide rail to coordinates (x1, y1), the second laser is adjusted to angle θ2 via a rotating platform, and the third laser adjusts the z-axis height via a lifting mechanism to achieve a focusing position shift. After the synchronous displacement of each unit, the landing points of the three laser beams on the spectral chip 4 form a precise triangle vertex. By adjusting the power of each laser, a continuous light spot can be formed at the edge. Closed-loop feedback control is used during the displacement process, and the position error is corrected in real time by the displacement sensor to ensure that the shape accuracy reaches the micrometer level.

[0059] Furthermore, by dynamically reconstructing the physical layout of the laser emission array, the limitations of traditional fixed light sources are overcome. Compared to static coding methods, dynamic shape coding has a higher information density—a single device can combine N lasers to create C(N,3) polygons, and supports real-time shape transformation for time-division multiplexing. For example, a six-laser array can generate at least 14 basic polygon configurations, which can be expanded to more effective coding forms with size scaling. This spatial-optical intensity dual modulation mechanism effectively improves the anti-interference capability of the communication system, while significantly enhancing communication security through a dynamic key update mechanism.

[0060] In one embodiment of this application, the laser emitting assembly 3 includes a plurality of laser emitters; the step of controlling the laser emitting assembly 3 to emit laser light to the spectral chip 4 based on the target emission shape includes:

[0061] Based on the shape of the target emission, the target laser emitter is determined from multiple laser emitters;

[0062] The target laser emitter is controlled to be in working condition so that the shape of the light emitted by the laser emitting component 3 is the same as the shape of the target light emission.

[0063] Understandably, based on the target emission shape, the target laser emitter is first identified from multiple laser emitters; that is, the laser emitted by the target laser emitter can be combined to obtain the target emission shape. Then, the target laser emitter is controlled to be in working state, emitting laser light into the spectral chip 4, so that the shape of the light emitted by the laser emitting component 3 is the target emission shape, thus completing the transmission of target information.

[0064] In some examples, the number of target laser emitters can be the same as or less than the total number of laser emitters.

[0065] Specifically, once the target emission shape (e.g., a triangle) is determined, the target shape is decomposed into a set of key points (e.g., vertices, intersections of edges). The theoretical coordinates of each key point are calculated, and these theoretical coordinates are compared with the actual projection positions of the laser array to select the optimal laser combination that covers the key points. For example, the vertex of a triangle may be formed by the superposition of the three nearest neighboring laser spots. If multiple laser combinations can generate the same shape (e.g., two different sets of lasers can both form a triangle), the combination with the most uniform light intensity distribution or the lowest energy consumption is preferred.

[0066] For example, suppose the laser array is arranged in a 5×5 matrix (coordinates (1,1)-(5,5)), and the target shape is the letter "L":

[0067] Extract the two key line segments of “L”: the vertical line segment (covering (1,1)-(1,5)) and the horizontal line segment (covering (1,1)-(5,1)).

[0068] Select lasers at coordinates (1,1), (1,3), and (1,5) to form a vertical line, and simultaneously activate lasers at coordinates (1,1), (3,1), and (5,1) to form a horizontal line.

[0069] By controlling the on / off state of the above 6 lasers, a high-contrast "L"-shaped light spot is formed on the spectral chip 4, completing the transmission of the "L" corresponding to the command (such as "emergency stop").

[0070] In one embodiment of this application, the laser emitting assembly 3 includes a plurality of laser emitters; the step of controlling the laser emitting assembly 3 to emit laser light to the spectral chip 4 based on the target laser arrangement order includes:

[0071] According to the target laser arrangement order, the movement of the laser emitter is controlled so that the arrangement order of the multiple laser beams emitted by the laser emitting component 3 is the same as the target laser arrangement order.

[0072] It is understandable that when controlling the laser emitting component 3 to emit laser to the spectral chip 4 according to the target emission shape, the movement of the laser emitter can be controlled first according to the target emission shape so that the arrangement order of the multiple beams emitted by multiple laser emitters is the target laser arrangement order. Then, the laser emitting component 3 is controlled to start working, so as to realize the arrangement order encoding by dynamically adjusting the physical position of the laser.

[0073] In some examples, each laser emitter is integrated on an independent motion platform, supporting three-dimensional displacement (such as XY plane translation, Z-axis lifting or rotation adjustment).

[0074] For example, the laser emitting assembly 3 includes multiple independently movable laser emitters, each of which can output a laser beam with specific optical parameters (such as wavelength, intensity, frequency, etc.). During implementation, when it is necessary to emit lasers according to the target laser arrangement sequence, the control module drives the physical position adjustment of each laser emitter according to a preset arrangement coding rule. For example, if the target sequence is "ACB", the B laser, originally located in the middle, is moved backward using a miniature guide rail or rotating bracket, while the C laser is moved forward to the middle position, so that multiple laser beams form a specific sequence arrangement in the spatial dimension. The spectral chip 4 detects the distribution of light spots at different positions and the corresponding spectral characteristics through its pixel array, and then resolves the coding information corresponding to the arrangement sequence.

[0075] For example, initially, three lasers are arranged equidistantly in a straight line (5cm apart). When a BAC arrangement is needed: first move laser B 10cm to the left to the leftmost position, then keep laser A in the center position, and finally shift laser C 10cm to the right.

[0076] In some embodiments, the laser emitting assembly 3 includes multiple laser emitters, each of which can emit multiple different laser beams, and the different laser emitters can emit the same laser beams; the step of controlling the laser emitting assembly 3 to emit laser to the spectral chip 4 based on the target laser arrangement order includes:

[0077] Based on the target laser arrangement order, the optical parameters of the laser emitted by the laser emitter are controlled and adjusted so that the arrangement order of the multiple laser beams emitted by the laser emitting component 3 is the same as the target laser arrangement order.

[0078] It is understandable that each laser emitter can emit multiple different laser beams, meaning the emitted laser beams can be adjusted as needed. The laser arrangement order is determined first based on the optical parameters of the different lasers. Therefore, when controlling the laser emitting component 3 to emit lasers to the spectral chip 4 based on the target laser arrangement order, the optical parameters of the lasers emitted by the laser emitter can be determined first based on the target laser arrangement order. Then, the operation of the laser emitter is controlled according to the determined optical parameters, thus ensuring that the multiple laser beams emitted by the laser emitting component 3 are arranged in the target laser arrangement order.

[0079] For example, the first laser emitter, the second laser emitter, and the third laser emitter are arranged in sequence, and the target laser is arranged in the order of a-band laser, b-band laser, and c-band laser. Then, the a-band laser emitted by the first laser emitter, the b-band laser emitted by the second laser emitter, and the c-band laser emitted by the third laser emitter are controlled and adjusted, so that the arrangement order of the multiple laser beams emitted by the laser emitting component 3 is the same as the arrangement order of the target laser.

[0080] In some embodiments, the optical parameters include at least one of wavelength, light intensity, and duration.

[0081] In some embodiments, after the step of controlling the laser emitting component 3 to emit laser light to the spectral chip 4, the following steps are included:

[0082] Acquire imaging images from spectral chip 4;

[0083] Adjust the position and / or orientation of at least one of the laser emitting component 3 and the spectral chip 4 according to the position of the light spot in the image.

[0084] It is understandable that when the laser emitted by the laser emitting component 3 falls on the spectral chip 4, a light spot appears in the image of the spectral chip 4. Based on the position of the light spot in the image, the relative positional relationship between the laser emitting component 3 and the spectral chip 4 can be determined. Furthermore, the position and / or orientation of at least one of the laser emitting component 3 and the spectral chip 4 can be adjusted so that the light spot is in the center of the image, ensuring that the spectral chip 4 can effectively receive the laser emitted by the laser emitting component 3, thereby improving the communication effect.

[0085] In some embodiments, at least one of the at least two optical communication devices 1 is provided with an energy receiving component 2, and the optical communication system further includes an energy transmitting device 5 for transmitting a light beam to the energy receiving component 2 to transfer energy to the energy receiving component 2. The control method of the optical communication system further includes:

[0086] Control the energy emitting device 5 to emit a beam of light to the energy receiving component 2;

[0087] The control energy receiving component 2 converts the light beam into electrical energy to power the optical communication device 1.

[0088] It is understandable that the energy transmitting device 5 emits a light beam to the energy receiving component 2, and the energy receiving component 2 can convert the light beam into electrical energy, and then use the electrical energy to power the optical communication device 1, thereby realizing remote wireless charging of the optical communication device 1.

[0089] In some examples, the energy emitting device 5 is, for example, a laser emitter, and the energy receiving component 2 is, for example, a solar panel or a photosensitive unit.

[0090] In some embodiments, the energy receiving component 2 includes a plurality of energy receiving units 21, which are arranged in a matrix; after the step of controlling the energy emitting device 5 to emit a light beam to the energy receiving component 2, the following steps are included:

[0091] Based on the received data from the energy receiving unit 21, the incident position of the beam emitted by the energy transmitting device 5 in the matrix-distributed energy receiving unit 21 is determined.

[0092] Based on the incident position, adjust the position and / or orientation of at least one of the energy emitting device 5 and the energy receiving component 2.

[0093] It is understandable that the received data of the energy receiving unit 21 that receives the beam emitted by the energy emitting device 5 will be different from that of the energy receiving unit 21 that does not receive the beam. Therefore, the incident position of the beam emitted by the energy emitting device 5 in the matrix-distributed energy receiving unit 21 can be determined based on the received data of the energy receiving unit 21.

[0094] Based on the incident position, it can be determined whether the current incident position meets the requirements. Then, the position and / or orientation of at least one of the energy emitting device 5 and the energy receiving component 2 can be controlled and adjusted based on the incident position to adjust the beam receiving effect of the energy receiving component 2.

[0095] In some examples, the position and / or orientation of at least one of the energy emitting device 5 and the energy receiving component 2 are adjusted so that the incident position is in the middle of the matrix energy receiving unit 21, so that the energy emitting device 5 can be continuously aligned with the energy receiving component 2, and the energy receiving component 2 can continuously receive energy, thus ensuring the energy receiving effect of the energy receiving component 2.

[0096] Specifically, the steps of adjusting the position and / or orientation of at least one of the energy transmitting device 5 and the energy receiving component 2 include:

[0097] Based on the received data from energy receiving component 2, determine the actual received energy of energy receiving component 2;

[0098] Based on the actual received energy, the incident position, and the target received energy, the position and / or orientation of at least one of the energy emitting device 5 and the energy receiving component 2 are controlled and adjusted.

[0099] It is understandable that different incident positions will affect the energy receiving effect of energy receiving component 2. Therefore, based on the actual received energy, incident position, and target received energy, the position and / or orientation of at least one of the energy transmitting device 5 and energy receiving component 2 can be controlled and adjusted so that the energy received by energy receiving component 2 is the target received energy.

[0100] According to an embodiment of the second aspect of this application, such as Figure 1 Optical communication systems, including:

[0101] At least two optical communication devices 1, at least one of the at least two optical communication devices 1 is provided with a power receiving component 2; and

[0102] Energy emitting device 5 is used to emit a beam of light to energy receiving component 2 in order to transmit energy to energy receiving component 2;

[0103] In this device, one of the at least two optical communication devices 1 is provided with a laser emitting component 3, and the other of the at least two optical communication devices 1 is provided with a spectral chip 4. The laser emitting component 3 is used to emit laser light to the spectral chip 4, and the spectral chip 4 receives the laser light emitted by the laser emitting component 3 to establish a communication connection between the at least two optical communication devices 1.

[0104] Understandably, one optical communication device 1 can emit a laser beam from the laser emitting component 3 to the spectral chip 4 of another optical communication device 1, thus establishing a communication connection between the two devices. Because lasers have strong anti-interference capabilities, they can effectively prevent the optical communication system from being interfered with or taken over, and are difficult to crack, resulting in higher security. Furthermore, only interfering light sources within the field of view of the spectral chip 4 can interfere with it, further enhancing the anti-interference capability and security of the optical communication system. Simultaneously, the energy emitting device 5 emits a beam of light to the energy receiving component 2, which converts the beam into electrical energy, thereby powering the optical communication device 1 and enabling remote wireless charging, allowing the device to maintain its operational status for extended periods.

[0105] It is understandable that long-distance, high-speed data transmission is achieved through beam carrier, thereby improving the single-channel rate.

[0106] In some examples, the energy emitting device 5 is, for example, a laser emitter, and the energy receiving component 2 is, for example, a solar panel or a photosensitive unit.

[0107] In some examples, based on the performance characteristics of the multispectral chip 4, it can achieve the resolution capability of n narrow-bandwidth different wavelengths. For example, the multispectral chip 4 PTS911 has the resolution capability of 32 narrow-band invisible light wavelengths, giving the transmitter sufficient coding space. The transmitter can arbitrarily select no more than n (32 for PTS911) wavelengths to form a transmission array according to the actual situation. The selected wavelengths are arranged spatially to form different shapes or sequences. The selected wavelengths are switched on and off, sending '01' information. Through narrow bandwidth, multiple wavelengths, spatial arrangement, and sequence transformation, it becomes almost impossible to generate identical interfering beams.

[0108] In some embodiments, such as Figure 2 Each optical communication device 1 includes a laser emitting component 3 and a spectral chip 4, so that any two optical communication devices 1 can establish a communication connection.

[0109] It is understandable that each optical communication device 1 has a laser emitting component 3 and a spectral chip 4. Thus, each optical communication device 1 can emit laser to other optical communication devices 1 through the laser emitting component 3, and each optical communication device 1 can receive laser emitted by other optical communication devices 1 through the spectral chip 4, thereby enabling communication connection between any two optical communication devices 1.

[0110] In some embodiments, such as Figure 2 At least two optical communication devices 1 include a host 11 and a terminal 12, with the host 11 communicating with the terminal 12 via laser.

[0111] It is understandable that both the host 11 and the terminal 12 are optical communication devices 1, which enables the host 11 to communicate with the terminal 12 via laser, realizing wireless communication between the host 11 and the terminal 12. It has strong anti-interference capabilities, which can effectively prevent the communication between the host 11 and the terminal 12 from being interfered with or taken over. It is also difficult to crack and has higher security, thus improving the anti-interference capability and security of the communication between the host 11 and the terminal 12.

[0112] In some embodiments, at least two optical communication devices 1 further include a repeater 13, the host 11 is connected to the repeater 13 via laser, and the repeater 13 is connected to the terminal 12 via laser.

[0113] It is understood that the host 11, repeater 13, and terminal 12 are all optical communication devices 1. The host 11 can communicate with the repeater 13 via laser, and the repeater 13 can communicate with the terminal 12 via laser, thereby enabling communication between the host 11 and the terminal 12. In other words, by adding the repeater 13, this embodiment not only enables communication between the host 11 and the terminal 12 but also helps to increase the communication distance between them.

[0114] In some embodiments, such as Figure 2 The optical communication system also includes a control unit 6, which is connected to the host 11 via optical fiber or laser.

[0115] It is understandable that the control unit 6 can communicate with the host 11 via optical fiber to enable information transmission between the control unit 6 and the host 11. The control unit 6 can also function as an optical communication device 1, communicating with the host 11 via laser to enable information transmission between the control unit 6 and the host 11.

[0116] In some examples, the user can send information or control commands to the host 11 through the control unit 6, and the host 11 can then send the information or control commands to the terminal, thereby realizing the control of the terminal.

[0117] In some embodiments, the optical communication device 1 includes a first pan-tilt unit, and an energy receiving component 2 is connected to the first pan-tilt unit. The first pan-tilt unit is used to adjust the orientation and / or position of the energy receiving component 2.

[0118] Understandably, the orientation and / or position of the energy receiving component 2 can be adjusted by the first gimbal so that the energy receiving component 2 is aligned with the energy emitting device 5, thereby enabling the energy receiving component 2 to effectively receive the laser emitted by the energy emitting device 5 and ensuring the energy receiving effect of the energy receiving component 2.

[0119] In some embodiments, the optical communication device 1 includes a second pan-tilt unit, and the spectral chip 4 is connected to the second pan-tilt unit. The second pan-tilt unit is used to adjust the orientation and / or position of the spectral chip 4.

[0120] It is understandable that the orientation and / or position of the spectral chip 4 can be adjusted by the second gimbal so that the spectral chip 4 is aligned with the laser emitting component 3, so that the spectral chip 4 can effectively receive the laser emitted by the laser emitting component 3, thus ensuring the photosensitive effect of the spectral chip 4 and thereby ensuring the communication effect.

[0121] In some embodiments, the optical communication device 1 includes a third gimbal, and the laser emitting component 3 is connected to the third gimbal. The third gimbal is used to adjust the orientation and / or position of the laser emitting component 3.

[0122] It is understandable that the orientation and / or position of the laser emitting component 3 can be adjusted by the third gimbal so that the spectral chip 4 is aligned with the laser emitting component 3, so that the spectral chip 4 can effectively receive the laser emitted by the laser emitting component 3, thus ensuring the photosensitive effect of the spectral chip 4 and thereby ensuring the communication effect.

[0123] In some embodiments, the laser emitting assembly 3 includes a plurality of laser emitters, at least some of which have different emission parameters, including at least one of the wavelength of the emitted laser, the intensity of the emitted laser, and the emission duration.

[0124] It is understandable that the laser emitted by a laser emitter will differ depending on its emission parameters. Therefore, by combining different laser emitters, multiple different laser combinations can be obtained. Each laser combination can represent a piece of information or a command, thereby enabling the establishment of a communication connection between two optical communication devices 1 using lasers.

[0125] In some embodiments, such as Figure 3 The energy receiving component 2 includes multiple energy receiving units 21, which are arranged in a matrix.

[0126] It is understandable that the multiple energy receiving units 21 are distributed in a matrix, which is beneficial to improving the structural regularity of the energy receiving component 2.

[0127] It is understandable that the multiple energy receiving units 21 distributed in the matrix can be used as a coordinate system. Based on the incident point of the light beam emitted by the energy emitting device 5 at the matrix, the incident position of the light beam emitted by the energy emitting device 5 can be determined. In turn, the relative positional relationship between the energy emitting device 5 and the energy receiving component 2 can be determined, which facilitates the subsequent adjustment of the position and / or orientation of at least one of the energy emitting device 5 and the energy receiving component 2 so that the energy received by the energy receiving component 2 can meet the requirements.

[0128] In some embodiments, the spectral chip 4 includes:

[0129] The photosensitive unit is used to acquire light of different wavelengths to obtain spectral information for each channel, where different channels correspond to spectral information of different wavelengths.

[0130] A filter unit is disposed on one side of the photosensitive unit and is located on the photosensitive path of the photosensitive unit. The filter unit filters the light entering the photosensitive unit and allows light of at least two different wavelengths to pass through.

[0131] According to the spectral chip 4 of this application embodiment, the photosensitive unit can acquire spectral information of different bands corresponding to different channels for spectral imaging. The photosensitive unit and the filter unit are one-to-one. The filter unit can filter the light entering the photosensitive unit, allowing light of two or more specific bands to pass through the filter unit and enter the photosensitive unit. This allows the photosensitive unit corresponding to a pixel to acquire spectral information of two or more different bands. In other words, by setting the filter unit to be able to transmit light of at least two different bands, this application enables a spectral chip 4 to simultaneously acquire spectral information of at least two different bands, reducing the physical interval between the two bands, improving resolution, and minimizing the loss of spectral information, thus improving subsequent imaging effects.

[0132] Understandably, in related technologies, the traditional RGB sensor structure consists of each photosensitive PD unit plus a corresponding filter unit, forming one pixel. To obtain spectral information in the red, yellow, and blue bands, at least three pixel units are needed. Due to the human eye's sensitivity to green, two green filter units are distributed every four pixels. If more bands, such as 12 light bands, are to be obtained, at least 12 pixels are needed. Regardless of the arrangement method, this will result in excessively large physical spacing between pixels in the same band or between adjacent bands, leading to low resolution and loss of spectral information.

[0133] For example, in a 12-band spectral arrangement, the 12 different light bands are arranged in a 4x3 format. Two adjacent identical channels (e.g., B12) are separated by 3 pixel units of other bands horizontally and 2 pixel units of other bands vertically. This can easily lead to excessive loss of spectral information within the same band, resulting in poor image quality in later stages.

[0134] This application configures the filter unit to transmit light in at least two different wavelengths, allowing a single pixel unit to simultaneously acquire spectral information from multiple wavelengths. For example, the filter unit can transmit 12 wavelengths, meaning one pixel unit can acquire information from 12 wavelengths. Consequently, adjacent identical channels are not separated by pixel units laterally or vertically, effectively reducing the physical distance between two wavelengths, improving resolution, and minimizing the loss of spectral information, thus enhancing subsequent imaging results.

[0135] Understandably, in related technologies, 12 channels require 12 pixels, meaning that to achieve the smallest photosensitive unit for n bands, n pixels are needed. If the value of n is too large, it can easily lead to a decrease in spatial resolution. However, this application integrates multiple channels (e.g., 12 channels) into a single pixel. This means that to achieve the smallest photosensitive unit for multiple bands, only one pixel is needed, which is beneficial for improving spatial resolution.

[0136] In some embodiments, the filtering unit includes at least one first filter film and at least one second filter film, wherein the refractive index of the first filter film is greater than the refractive index of the second filter film, and the first filter film and the second filter film are alternately arranged.

[0137] It is understandable that by alternately stacking first and second filter films with different refractive indices to form a filter unit, the filter unit can transmit light of at least two different wavelengths, thus enabling the same filter unit to obtain light of multiple different wavelengths. In other words, the spectral splitting structure of multiple wavelengths is the same. Therefore, the filter unit of this application does not require repeated etching and cleaning steps during fabrication, making the process simple and the cost low.

[0138] In some examples, this application employs multilayer film technology, using alternating stacks of high-refractive-index filter films (such as titanium oxide, specifically titanium oxide or titanium dioxide) and low-refractive-index filter films (such as SiO2). By combining the different thicknesses of these two films, at least one narrow-band transmission peak light band can pass through the filter unit, enabling a single filter unit to transmit light bands with multiple independent narrow-band transmission peaks, such as two, four, or seven. For example, a single filter unit can achieve four independent narrow-band transmission peaks with center wavelengths of 450 nm, 550 nm, 650 nm, and 750 nm.

[0139] It should be noted that, based on functional requirements and performance parameters, the wavelength range of the transmitted narrowband transmission peak can be adjusted to be the center wavelength ± (1nm-100nm), and the full width at half maximum (FWHM) ≤ (1nm-100nm) by adjusting the materials used in the first and second filter films, the alternating stacking of high and low refractive index materials, and the thickness combination. For example, if the center wavelength of the transmitted light is 550nm, then the actual transmitted narrowband transmission peak wavelength range is 550nm ± (1nm-100nm); if the center wavelength is 450nm, then the narrowband transmission peak wavelength range is 450nm ± (1nm-100nm). Crosstalk suppression between multiple narrowband transmission peaks transmitted by the same filter unit should be sufficiently low, such as an isolation of ≥30dB between adjacent bands, ensuring sufficient independence of the corresponding quantum-responsible optical channel data.

[0140] In some examples, the first and second filter films can be made of any of the following materials: aluminum (Al), chromium (Cr), gold (Au), silver (Ag), silicon (Si), germanium (Ge), aluminum oxide (Al₂O₃), cerium oxide (CeO₂), hafnium dioxide (HfO₂), indium tin oxide (ITO), magnesium oxide (MgO), niobium pentoxide (Nb₂O₅), silicon monoxide (SiO₂), silicon dioxide (SiO₂), titanium dioxide (TiO₂), titanium trioxide (Ti₃O₅), tantalum pentoxide (Ta₂O₅), yttrium oxide (Y₂O₃), zinc oxide (ZnO), zirconium oxide (ZrO₂), aluminum fluoride (AIF₃), magnesium fluoride (MgF₂), calcium fluoride (CaF₂), ytterbium fluoride (YbF₃), yttrium fluoride (YF₃), zinc sulfide (ZnS), and zinc selenide (ZnSe).

[0141] Specifically, the thickness of different first filters varies.

[0142] It is understandable that when the number of first filter films is at least two, by adjusting the thickness of different first filter films, the number of light bands that can be transmitted by the filter unit composed of the first filter films can be changed, or the range of light bands that can be transmitted by the filter unit can be changed.

[0143] Specifically, the thickness of different second filters varies.

[0144] It is understandable that when the number of second filter films is at least two, by adjusting the thickness of different second filter films, the number of light bands that can be transmitted by the filter unit composed of the second filter films can be changed, or the range of light bands that can be transmitted by the filter unit can be changed.

[0145] Specifically, the first and second filter films have different thicknesses.

[0146] It is understandable that by adjusting the thickness of the first filter film and the second filter film, making the thicknesses of the first filter film and the second filter film different, the number of light bands that the filter unit composed of the first filter film and the second filter film can transmit, or the range of light bands that the filter unit can transmit, can be changed.

[0147] In some examples, the thickness of the first filter film and the second filter film can also be the same.

[0148] In some embodiments, the filter unit includes at least two filter regions, and different filter regions allow light of different wavelengths to pass through.

[0149] It is understandable that different filter areas can transmit light of different wavelengths, thus enabling the filter unit to transmit light of at least two different wavelengths simultaneously.

[0150] Specifically, the thickness varies in different filter zones.

[0151] It is understandable that by making the thickness of the filter medium different in different filter areas, different filter areas can allow light of different wavelengths to pass through.

[0152] Specifically, the materials used in different filter zones are different.

[0153] It is understandable that by using different materials for the filter medium in different filter areas, different filter areas can allow light of different wavelengths to pass through.

[0154] According to the embodiments of the third aspect of this application, such as Figure 1 Optical communication systems, including:

[0155] Optical communication device 1, the optical communication device 1 is provided with energy receiving component 2, the energy receiving component 2 includes photosensitive receiver 211; and

[0156] Energy emitting device 5 is used to emit a beam of light to energy receiving component 2 in order to transmit energy to energy receiving component 2;

[0157] The energy emitting device 5 includes multiple emitting elements with different emitting parameters. The emitting elements are used to emit lasers to the photosensitive receiving device 211, and the photosensitive receiving device 211 receives the lasers emitted by the emitting elements to establish a communication connection between the energy emitting device 5 and the optical communication device 1.

[0158] According to the optical communication system of the present application embodiment, by controlling the working state of the transmitting element, each transmitting element can switch between working and not working, that is, each transmitting element can emit laser or not emit laser, and each transmitting element has two working modes.

[0159] Meanwhile, since different emitting elements have different emission parameters, meaning that different emitting elements emit different lasers, the photosensitive receiver 211 can distinguish which emitting element emitted the received laser. Therefore, after receiving the laser, the photosensitive receiver 211 can determine the operating state of each emitting element.

[0160] In other words, by changing the operating state of different emitting elements, multiple emitting elements can emit various different laser combinations. Since the emission parameters of different emitting elements are different, the photosensitive receiver 211 can identify the laser combinations emitted by multiple emitting elements. Furthermore, the laser combinations emitted by multiple emitting elements can be used to transmit commands or information, enabling the establishment of a communication connection between the energy emitting device 5 and the optical communication device 1 using laser communication. Because lasers have strong anti-interference capabilities, they can effectively prevent the communication device from being interfered with or taken over, and are difficult to crack, resulting in higher security and improved anti-interference capabilities and security of the communication device.

[0161] It is understandable that by using a photosensitive receiver 211 to receive the light beam, and by using a high-frequency transmission switch to control the transmitting element, the transmission rate of a single band can be greater than 2Gbps.

[0162] It is understandable that by changing the operating state of different emitting elements, multiple emitting elements can generate multiple different laser combinations, that is, multiple emitting elements can generate multiple different optical codes, allowing multiple emitting elements to use optical codes to transmit instructions or information. When the photosensitive receiving device 211 receives the laser combination, because the emission parameters of different emitting elements are different, it can determine which emitting elements emitted the currently received laser combination. In other words, it can decode the optical codes generated by multiple emitting elements to obtain the instructions or information transmitted by multiple emitting elements.

[0163] The instruction or information to be transmitted can be converted into optical code, and then the optical code is transmitted to the photosensitive receiver 211 by laser combination through multiple transmitting elements. The photosensitive receiver 211 can receive the laser combination and then decode the optical code into the corresponding instruction or information to realize communication.

[0164] In some examples, assuming the number of emitting elements is n, multiple emitting elements can generate at least 2 n A combination of lasers, i.e., n emitting elements, can produce 2 n If optical encoding is used, then n lasers can transmit 2... n Such instructions or information.

[0165] Understandably, the information to be transmitted can be converted into a combination of one or more lasers to enable the transmission of information to a photosensitive receiving device using multiple emitting elements.

[0166] For example, the emission parameters of the first emitting element are A, the emission parameters of the second emitting element are B, and the emission parameters of the third emitting element are C. The operating state of the first emitting element is defined as A1, and the inactive state as A2; the operating state of the second emitting element is defined as B1, and the inactive state as B2; and the operating state of the third emitting element is defined as C1, and the inactive state as C2. Then, the laser combinations that the first, second, and third emitting elements can generate include A1+B1+C1, A1+B1+C2, A1+B2+C1, A1+B2+C2, A2+B1+C1, A2+B1+C2, A2+B2+C1, and A2+B2+C2.

[0167] For example, the laser combination A1+B1+C1 can be used to represent the command or information of "forward", and the laser combination A1+B1+C2 can be used to represent the command or information of "backward". It should be noted that this is only an example and is not a special limitation.

[0168] In some cases, the information represented by different laser combinations generated by multiple transmitting elements can be pre-stored in the photosensitive receiver or the transceiver device where the photosensitive receiver is located. When the photosensitive receiver receives the laser combinations generated by multiple transmitting elements, it can determine the specific information represented by the received laser combination and thus decode the laser combination.

[0169] For example, the emission parameters include at least one of the wavelength of the emitted laser, the intensity of the emitted laser, and the emission duration.

[0170] Understandably, when different emitting elements emit lasers with different wavelengths, the photosensitive receiving device can determine which emitting elements emitted the laser based on the wavelength of the received laser, that is, it can determine which emitting elements are in working condition.

[0171] It can be understood that when different emitting elements emit lasers with different intensities, the specific emitting elements that emitted the lasers can be determined based on the intensity of the lasers received by the photosensitive receiving device, which means it can be determined which emitting elements are in working condition.

[0172] It can be understood that when different emitting elements emit lasers for different durations, the specific emitting elements that emitted the lasers can be determined based on the duration of the lasers received by the photosensitive receiving device, which means it can be determined which emitting elements are in working condition.

[0173] It is understandable that when different emitting elements emit lasers with different wavelengths, the light intensity of at least some of the emitting elements can be changed, thereby increasing the number of laser combinations that can be generated by multiple emitting elements. For example, when the number of emitting elements is n, the number of laser combinations that can be generated by n emitting elements is 2n. n When the light intensity of the emitting element can be changed, assuming the light intensity of the emitting element can switch between a first light intensity and a second light intensity, then an emitting element can have three states: not working, working but emitting laser light intensity of the first light intensity, and working but emitting laser light intensity of the second light intensity. Therefore, the number of laser combinations that can be generated by n emitting elements is 3. n indivual.

[0174] It is understandable that when different emitting elements emit lasers with different wavelengths, the duration of the laser emitted by at least some of the emitting elements can be changed, thereby increasing the number of laser combinations that can be generated by multiple emitting elements. For example, when the number of emitting elements is n, the number of laser combinations that can be generated by n emitting elements is 2n. n When the duration of the laser reflected by the emitting element can be changed, assuming the duration of the laser emitted by the emitting element can switch between 0ms, 10ms, 20ms, and 30ms, then one emitting element can have four states. Therefore, the number of laser combinations that can be generated by n emitting elements is 4. n indivual.

[0175] In one embodiment of this application, such as Figure 6 As shown, the energy receiving component 2 includes multiple energy receiving units 21, and each energy receiving unit 21 is provided with a photosensitive receiving device 211.

[0176] It is understandable that each energy receiving unit 21 is equipped with a photosensitive receiving device 211. Each photosensitive receiving device 211 can receive light of the same multiple wavelengths. Thus, as long as the light beam emitted by the energy transmitting device 5 shines on the photosensitive receiving device 211 of one of the energy receiving units 21, the information can be transmitted, thereby improving the fault tolerance rate.

[0177] like Figure 7 As shown below, examples illustrate how optical communication systems can be applied to UAV flight control:

[0178] The optical communication system mainly includes three data paths: energy transmission, control command transmission, and high-speed data transmission, which respectively complete the functions of energy supply, UAV management and control, and image acquisition.

[0179] The beam emitting unit transmits energy to the energy receiving unit via beam c1, and the energy receiving unit converts the energy to continuously supply the UAV's power module. Simultaneously, beam c1 can also serve as a carrier wave to transmit high-speed signals, which can be control or flight control commands.

[0180] The multispectral emission array emits spectra of different wavelengths to represent different control or flight control commands. These commands are then emitted into a second multispectral array via a combined laser beam a1. The second multispectral array analyzes the captured images to extract the corresponding commands.

[0181] Images captured by the first multispectral method, such as ground vegetation, can be transmitted to the image receiving end via conventional electromagnetic method B, or they can be transmitted to the optical resolution unit via carrier beam b1.

[0182] In practical applications, beam c1 or beam a1 can be used alone as the transmission method for control commands, or the two can be used in combination, or they can be used as mutual backups or mutual verifications to achieve a more advanced safety control mechanism.

[0183] When a drone is detected to have deviated from its intended flight path, a top-level takeover command is sent via beam c1 to obtain control of the drone. Then, a special command is sent again via laser beam a1, such as a fully open beam of four combined wavelengths: 430nm, 550nm, 680nm, and 810nm. After confirming that the drone has been completely taken over, the next command is obtained through either of these two methods, such as controlling the drone to return to its original intended flight path.

[0184] Control steps for one application example:

[0185] 1. Beam c1 transmits code 4'b1111, the energy receiving unit parses and obtains command code 4'b1111, and temporarily gains control of the drone;

[0186] 2. Beam a1 transmits at full range in the 430nm, 550nm, 680nm, and 810nm bands, characterizing the code 4'b1111, and confirms again that control of the UAV is permitted;

[0187] 3. Continue to send subsequent UAV control commands via beam c1 or beam a1 to guide the UAV back to the correct flight path;

[0188] 4. If a command other than 4'b1111 is sent in step 2 beam a1, then control of the aircraft is released and the control action is terminated.

[0189] The above control process can also be adapted to obtain control of the drone by selecting only one method from either step 1 or step 2, depending on the safety level requirements.

[0190] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
