Description

Multi-light fusion optical system and sight Technical Field

[0001] The present invention relates to the field of optical imaging technology, and in particular to a multi-light fusion optical system and a sight. Background Art

[0002] Traditional red dot sights are widely used outdoors. They offer fast aiming, ease of use, portability, and the ability to clearly see the target's details while aiming with the red dot. When searching for a target with eyes open, the red dot is directly in your field of view, allowing you to accurately find and aim at the target without changing your field of view. However, conventional red dot sights can only be used during the day and cannot be used at night or in low-light environments, limiting their use cases. Furthermore, the red dot of a red dot sight is typically reflected by a curved reflector, which is located in the direction of the human eye. This can cause parallax errors when observing the real scene through the curved reflector, affecting the aiming effect and user experience.

[0003] Summary of the Invention

[0004] In view of this, the present invention aims to provide an improved multi-light fusion optical system and a sight, so as to solve the problem that the existing sight cannot be used at night and during the day at the same time and has parallax.

[0005] In one aspect, the present application provides a multi-light fusion optical system, comprising:

[0006] an aiming mark light source, for generating an aiming mark light signal;

[0007] An imaging component is used to collect light signals in a target scene and form a scene image, and display the scene image on a display module;

[0008] A light combining mirror assembly, wherein the aiming mark light source and the display module are respectively located on different sides of the light combining mirror assembly;

[0009] a semi-transparent and semi-reflective mirror, wherein the fused light signal after the aiming mark light signal and the scene image light signal are fused by the light combining mirror assembly is propagated along the fusion optical axis and transmitted through the semi-transparent and semi-reflective mirror; and

[0010] The reflector, the light combining mirror assembly, the semi-transparent and semi-reflective mirror and the reflector are arranged in sequence along the fusion optical axis. The fusion light signal transmitted through the semi-transparent and semi-reflective mirror is reflected by the reflector and then directed toward the semi-transparent and semi-reflective mirror. After being reflected by the semi-transparent and semi-reflective mirror, it deviates from the fusion optical axis and is directed toward the human eye observation position along the entrance pupil optical axis.

[0011] In some embodiments, the light combining mirror assembly includes a prism assembly and a light combining surface provided on the prism assembly, and the light combining surface is inclined relative to the fusion optical axis;

[0012] The light signal of the scene image is incident on one side of the light-combining surface along the direction of the fusion optical axis and is transmitted through the light-combining surface, and the light signal of the aiming mark is incident on the other side of the light-combining surface and is reflected by the light-combining surface and propagates along the direction of the fusion optical axis together with the light signal of the scene image; or, the light signal of the aiming mark is incident on one side of the light-combining surface along the direction of the fusion optical axis and is transmitted through the light-combining surface, and the light signal of the scene image is incident on the other side of the light-combining surface and is reflected by the light-combining surface and propagates along the direction of the fusion optical axis together with the light signal of the aiming mark.

[0013] In some embodiments, the prism assembly includes a first prism and a second prism disposed opposite to each other, and the light-combining surface is a semi-transparent and semi-reflective film disposed between the first prism and the second prism.

[0014] In some embodiments, the multi-light fusion optical system has a light entrance window on a side of the semi-transparent and semi-reflective mirror away from the human eye observation position, and the light entrance window is arranged on the entrance pupil optical axis.

[0015] In some embodiments, the multi-light fusion optical system further includes a collimating mirror assembly, wherein the collimating mirror assembly and the reflector are respectively located on opposite sides of the semi-transparent and semi-reflective mirror. After the aiming mark light signal and the scene image light signal are fused, they are calibrated by the collimating mirror assembly to form parallel light, and then emitted toward the semi-transparent and semi-reflective mirror along the direction of the fusion optical axis.

[0016] In some embodiments, the collimating mirror assembly includes a plurality of optical lenses, and the plurality of optical lenses include a biconcave lens close to one side of the light combining mirror assembly and a biconvex lens close to one side of the semi-transparent and semi-reflective mirror.

[0017] In some embodiments, the semi-transparent and semi-reflective mirror is a plane mirror with a semi-transparent and semi-reflective film on its surface, and the plane mirror is tilted relative to the fusion optical axis and the entrance pupil optical axis.

[0018] In some embodiments, the entrance pupil optical axis and the fusion optical axis are located in the same plane and are perpendicular to each other.

[0019] In some embodiments, the imaging component also includes an objective lens and an imaging detector corresponding to the objective lens; the objective lens is used to converge the light signal in the target scene and shoot it toward the imaging detector, and the imaging detector is used to convert the converged light signal into an image signal and send it to the display module for display.

[0020] On the other hand, the present application also provides a sight having the multi-light fusion optical system as described above.

[0021] The multi-light fusion optical system provided by the present invention has an aiming mark light source capable of generating an aiming mark light signal, an imaging component capable of collecting light signals in a target scene and forming a scene image, and the aiming mark light signal and the light signal of the scene image are fused by the light combining mirror component, transmitted through a semi-transparent and semi-reflective mirror along a fusion optical axis, and emitted toward a reflective mirror, reflected by the reflective mirror, and emitted toward a semi-transparent and semi-reflective mirror, and after being reflected by the semi-transparent and semi-reflective mirror, deviate from the fusion optical axis and emit toward the human eye observation position along an entrance optical axis, and then enter the human eye.

[0022] The imaging component forms a scene image of the target scene through imaging, and fuses the light signal of the scene image with the light signal of the aiming mark and presents it to the user, which can meet the effect of use in day and night environments and enrich the usage scenarios. The aiming mark light source can assist the user to quickly aim at the target. Through the multi-light fusion method, the multi-light fusion optical system has the characteristics of fast aiming and rich usage scenarios, which is convenient for users to use and improves the user experience. Secondly, after fusion, the aiming mark light signal and the light signal of the scene image first propagate along the fusion optical axis. The reflector is located at the rear end of the fusion optical axis. After the fusion light signal is reflected by the reflector to the semi-transparent and semi-reflective mirror, it deviates from the fusion optical axis after reflection by the semi-transparent and semi-reflective mirror and propagates along the entrance optical axis. That is, the fusion optical axis and the entrance optical axis are not in the same direction. The multi-spectral fusion light signal first propagates along the fusion optical path and then propagates along the entrance pupil optical axis to enter the human eye. The light signal of the eyepiece scene directly passes through the semi-transparent and semi-reflective mirror along the entrance pupil optical axis and continues to propagate into the human eye. That is, the human eye sees the outside scene directly through the flat window piece without passing through the curved lens, thereby avoiding the problem of parallax.

[0023] In the above embodiments, the sight and the corresponding multi-light fusion optical system embodiments are of the same concept, and thus have the same technical effects as the corresponding multi-light fusion optical system embodiments, which will not be described in detail here.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) are only used to explain the relative position relationship between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] It should also be noted that when an element is referred to as being “fixed on” or “disposed on” another element, the element may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0030] Referring to Figures 1 and 2, an embodiment of the present invention provides a multi-light fusion optical system 10, comprising a sighting mark light source 12, an imaging assembly 14, a light combining lens assembly 16, a semi-transparent and semi-reflective mirror 18, and a reflector 20. The light combining lens assembly 16, the semi-transparent and semi-reflective mirror 18, and the reflector 20 are sequentially arranged along the fusion optical axis. The specific use scenario of the multi-light fusion optical system 10 is not limited, and examples include sights, telescopes, and the like. Specifically, in this application, the multi-light fusion optical system 10 is used in a sight.

[0031] The aiming mark light source 12 can generate an aiming mark light signal, such as a red dot. The imaging component 14 can collect the light signal in the target scene and form a scene image, which is then displayed on the display module 22. The aiming mark light source 12 and the display module 22 are located on different sides of the light combining mirror component 16. The aiming mark light signal and the light signal of the scene image are fused by the light combining mirror component 16 and propagate along the fusion optical axis 24. Since the multi-light fusion optical system 10 has both the aiming mark light source 12 and the imaging component 14, the imaging component 14 can form a scene image of the target scene. The light signal of the scene image is fused with the aiming mark light signal and presented to the user, allowing the sight to meet the requirements of day and night use. That is, the sight can be used not only during the day but also at night or in low-light environments. The aiming mark light signal generated by the aiming mark light source 12 can assist the user in quickly aiming at the target. Through multi-light fusion, the multi-light fusion optical system 10 has the characteristics of fast aiming and rich usage scenarios, making it convenient for users to use and improving the user experience.

[0032] The specific type of the aiming mark light source 12 is not limited. For example, it can be a red point light source that can form a red point, such as an LED lamp.

[0033] The semi-transparent mirror 18 has the effect of both transmitting and reflecting the light passing through it. That is, when the light passes through the semi-transparent mirror 18, part of the light will pass through the semi-transparent mirror 18, while the remaining part will be reflected by the semi-transparent mirror 18, preventing it from passing through the semi-transparent mirror 18. The reflector 20 is capable of reflecting light and is located at the rear end of the fusion optical axis 24. The fused light signal formed by the fusion of the aiming mark light signal and the scene image light signal is transmitted through the semi-transparent mirror 18 along the fusion optical axis 24 and emitted to the reflector 20. The fused light signal that passes through the semi-transparent mirror 18 is reflected by the reflector 20 and then emitted back to the semi-transparent mirror 18. After being reflected by the semi-transparent mirror 18, it deviates from the fusion optical axis 24 and is emitted along the entrance optical axis 26 toward the human eye observation position, thereby entering the human eye. After the aiming mark light signal and the scene image signal are fused, they first propagate along the fusion optical axis 24, pass through the semi-transparent and semi-reflective mirror 18, and are reflected by the reflector 20, and are re-emitted to the semi-transparent and semi-reflective mirror 18. After being reflected by the semi-transparent and semi-reflective mirror 18, they deviate from the fusion optical axis 24 and enter the human eye along the optical axis 26. That is, the fusion optical axis 24 and the optical axis 26 are not in the same direction. The light signal of the target scene that directly enters the human eye propagates along the optical axis 26, and the reflector 20 is at the rear end of the fusion optical axis 24. Therefore, the reflector 20 does not reflect the light signal of the fused scene image. The reflection direction of the aiming mark light signal (i.e., the direction of the fusion optical axis) and the direction in which the light signal of the fused scene image and the aiming mark light signal are incident on the human eye (i.e., the direction of the entrance pupil optical axis) are not coaxial, so that the user cannot see the reflector 20 during the aiming process. The multi-spectral fusion light signal first propagates along the fusion optical path and then propagates along the entrance pupil optical axis to enter the human eye. The light signal of the eyepiece scene directly passes through the semi-transparent and semi-reflective mirror 18 along the entrance pupil optical axis and continues to propagate into the human eye. That is, the human eye can see the outside scene directly through the flat window film without passing through the curved lens, thereby avoiding the problem of parallax.

[0034] In one embodiment, the incident optical axis 26 and the fusion optical axis 24 are located in the same plane and are perpendicular to each other.

[0035] The specific imaging mode of the imaging component 14 is not limited. For example, it can be an infrared imaging component, a low-light imaging component, a digital imaging component, or an imaging component combining infrared and low-light.

[0036] In one embodiment, the imaging component 14 includes an objective lens 28, an imaging detector 30 arranged corresponding to the objective lens 28, and a display module 22 electrically connected to the imaging detector 30. The objective lens 28 is used to converge the light signal in the target scene and direct it toward the imaging detector 30. The imaging detector 30 is used to convert the converged light signal into an image signal and send the image signal to the display module 22 for display. The image displayed on the display module 22 is then transmitted to the light combining mirror component 16 in the form of an optical signal.

[0037] In the present application, the objective lens 28 is a lens that can transmit infrared rays, the imaging detector 30 is an infrared sensor, and the display module 22 is a display screen. The infrared signal generated by the target passes through the objective lens 28 and is received by the infrared sensor. The display screen can receive the infrared signal from the infrared sensor and display a scene image corresponding to the target scene based on the infrared signal.

[0038] The specific positions of the objective lens 28 and the imaging detector 30 relative to the light combining mirror assembly 16 are not limited, and they can be directly in front of the light combining mirror assembly 16, or above or beside the light combining mirror assembly 16.

[0039] In one embodiment, the light combining mirror assembly 16 includes a prism assembly 32 and a light combining surface 34 disposed on the prism assembly 32. The light combining surface 34 is inclined relative to the fusion optical axis 24. The aiming mark light signal and the scene image light signal are combined at the light combining surface 34 and then propagate along the fusion optical axis 24 toward the reflector 20. Specifically, the angle between the light combining surface 34 and the fusion optical axis 24 is preferably 45°.

[0040] The display module 22 and the aiming mark light source 12 are respectively located on opposite sides of the light combining surface 34 and are conjugately arranged. Therefore, the relative positions of the display module 22 and the aiming mark light source 12 can be interchanged.

[0041] In one embodiment, the light signal of the scene image is incident on one side of the light-combining surface 34 along the direction of the fusion optical axis 24 and is transmitted through the light-combining surface 34. The light signal of the aiming mark is incident on the other side of the light-combining surface 34 and, after being reflected by the light-combining surface 34, propagates together with the light signal of the scene image along the direction of the fusion optical axis 24. The display module 22 is located on the side of the light-combining surface 34 away from the reflector 20 in the direction of the fusion optical axis 24. The aiming mark light source 12 is located on the other side of the light-combining surface 34 and outside the fusion optical axis 24. That is, the display module 22, the light-combining surface 34, the semi-transparent and semi-reflective mirror 18, and the reflector 20 are arranged in sequence on the fusion optical axis 24. The aiming mark light source 12 is arranged offset from the fusion optical axis 24. The incident direction of the light signal of the scene image is parallel to the fusion optical axis, and the incident direction of the aiming mark light signal is perpendicular to the fusion optical axis.

[0042] In another embodiment, the aiming mark light signal is incident on one side of the light combining surface 34 along the direction of the fusion optical axis 24 and is transmitted through the light combining surface 34, and the light signal of the scene image is incident on the other side of the light combining surface 34, and after being reflected by the light combining surface 34, it propagates together with the aiming mark light signal along the direction of the fusion optical axis 24, that is, the aiming mark light source 12 is located on the side of the light combining surface 34 away from the reflector 20 in the direction of the fusion optical axis 24, and the display module 22 is located on the other side of the light combining surface 34 and outside the fusion optical axis 24, that is, the aiming mark light source 12, the light combining surface 34, the semi-transparent and semi-reflective mirror 18, and the reflector 20 are arranged in sequence on the fusion optical axis 24, the display module 22 is arranged away from the fusion optical axis 24, and the incident direction of the aiming mark light signal is parallel to the fusion optical axis, and the incident direction of the light signal of the scene image is perpendicular to the fusion optical axis.

[0043] The prism assembly 32 includes a first prism 36 and a second prism 38 disposed opposite each other. The light-combining surface 34 is a semi-transparent, semi-reflective film located between the first prism 36 and the second prism 38. The semi-transparent, semi-reflective film can simultaneously transmit and reflect light passing through it. When the aiming mark light signal and the scene image light signal propagate through the semi-transparent, semi-reflective film, both transmit and reflect. In the first embodiment described above, the portion of the scene image light signal that passes through the semi-transparent, semi-reflective film and the portion of the aiming mark light signal that is reflected by the semi-transparent, semi-reflective film are combined at the semi-transparent, semi-reflective film. In the second embodiment described above, the portion of the aiming mark light signal that passes through the semi-transparent, semi-reflective film and the portion of the scene image light signal that is reflected by the semi-transparent, semi-reflective film are combined at the semi-transparent, semi-reflective film.

[0044] In this embodiment, the first prism 36 and the second prism 38 are both triangular prisms, which are assembled into a quadrangular prism. A semi-transparent and semi-reflective film is provided on the side of one prism close to the other prism, and the display module 22 and the aiming mark light source 12 are respectively located on the adjacent two sides of the quadrangular prism.

[0045] In one embodiment, the multi-light fusion optical system 10 further includes a collimator assembly 40. The collimator assembly 40 and the reflector 20 are located on opposite sides of the semi-transparent and semi-reflective mirror 18. After the aiming mark light signal and the scene image light signal are fused, they are collimated by the collimator assembly 40 to form parallel light, which is then emitted toward the semi-transparent and semi-reflective mirror 18 along the fusion optical axis 24. By disposing the collimator assembly 40 between the light combining lens assembly 16 and the semi-transparent and semi-reflective mirror 18, the collimator assembly 40 can calibrate the light passing through it to form parallel light, thereby collimating the aiming mark light signal, i.e., the red dot, generated by the aiming mark light source 12. This ensures that the red dot remains clear and undistorted both at the center and at the edge, preventing the red dot from being diffused or distorted when the human eye deviates from the image, thereby significantly improving the product's performance and user experience. Furthermore, the collimator assembly 40 has a focal length, which can magnify the scene image displayed by the display module 22 for easier viewing.

[0046] The number of optical lenses included in the collimator assembly 40 is not limited, and for example, it can be composed of 1, 2, 3, or more lenses. In this embodiment, the collimator assembly 40 includes two optical lenses, namely a biconcave lens 42 and a biconvex lens 44. The biconcave lens 42 and the biconvex lens 44 are bonded and fixed together, and the biconcave lens 42 is close to the light combining lens assembly 16, and the biconvex lens 44 is close to the semi-transparent and semi-reflective mirror 18.

[0047] In one embodiment, the semi-transparent and semi-reflective mirror 18 is a plane mirror having a semi-transparent and semi-reflective film on its surface. The plane mirror and the semi-transparent and semi-reflective film located thereon are tilted relative to the convergence optical axis 24 and the optical axis 26. The semi-transparent and semi-reflective film on the plane mirror can simultaneously transmit and reflect light passing through it. When parallel light, which has been collimated by the collimating lens assembly 40, reaches the semi-transparent and semi-reflective film on the plane mirror, part of the light is reflected away, while the remaining part passes through the semi-transparent and semi-reflective film and propagates to the reflector 20. When the light is reflected by the reflector 20 and then returned to the semi-transparent and semi-reflective film, part of the light passes through the semi-transparent and semi-reflective film, while part of the light is reflected by the semi-transparent and semi-reflective film and enters the human eye along the optical axis 26. In addition, compared to curved mirrors, plane mirrors can prevent parallax errors during observation.

[0048] Specifically, the angles between the plane mirror and the semi-transparent and semi-reflective film located thereon and the fusion optical axis 24 and the incident optical axis 26 are preferably 45°.

[0049] The multi-light fusion optical system 10 has a light intake window on the side of the semi-transparent and semi-reflective mirror 18, away from the human eye observation position. The light intake window and the human eye observation position are respectively located at the front and rear ends of the sight along the optical input axis 26. Visible light reflected by the target, such as white light, can enter the multi-light fusion optical system 10 through the light intake window and pass through the semi-transparent and semi-reflective mirror 18 along the optical input axis 26 to the human eye. During observation, the user can simultaneously see the image on the display module 22, the red dot generated by the aiming mark light source 12, and the real scene, achieving a fusion of the image, the red dot, and the real scene.

[0050] In one embodiment, the reflector 20 is a curved mirror with a concave surface on the side closest to the translucent and semi-reflective film. The curved mirror has a focal length. Parallel light, collimated by the collimating lens assembly 40, passes through the semi-reflective mirror 18 and reaches the reflector 20. When the light is reflected by the semi-reflective mirror 18, the reflector 20 amplifies the scene image displayed by the display module 22, forming a larger scene image for the human eye.

[0051] The technical solution provided by this application ensures that when in use, the human eye can see the outside scene directly through the flat window film, without having to look through the curved lens. Traditional red dot sights use curved reflections to form images, and the human eye's field of view must pass through the curved reflector to see the outside scene, which results in parallax compared to flat window films. This application adds a flat mirror in front of the curved reflector, placing it to the right of the human eye. This prevents the human eye from looking through the curved mirror, thus eliminating parallax.

[0052] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
