Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of imaging equipment, and in particular to a binocular telescope. BACKGROUND

[0002] In the structural design of existing binocular telescopes (including infrared binocular telescopes), since the observation images need to be provided for the left and right eyes of a user at the same time, two sets of optical path structures need to be designed when the whole telescope is designed, for example, each set of optical path structure includes an objective lens, an imaging detector (such as an infrared detector), a display (such as an OLED display), and an eyepiece, which results in that the overall volume, weight, and power consumption of the whole telescope are too large, the hardware cost is too high, and the user experience is poor. SUMMARY

[0003] The purpose of the present application is to provide a binocular telescope, which only needs to be provided with one display, one eyepiece, and one beam splitter, so as to reflect the light to the first reflector and the second reflector respectively, form a double-channel optical path for the left eye and the right eye of a user to observe images at the same time, and simplify the structural arrangement, reduce the overall cost, and reduce the power consumption.

[0004] To achieve the above purpose, the present application provides the following technical scheme: A binocular telescope is provided, which comprises: An imaging sensor for sensing the light reflected from an object and generating an image based on the sensed light; A display electrically connected to the imaging sensor for displaying the image generated by the imaging sensor; An eyepiece arranged on the side of the display close to the image side for modulating the light emitted by the display into parallel light; A beam splitter, a first reflector, a second reflector, a left eyepiece tube, and a right eyepiece tube; The beam splitter is arranged on the side of the eyepiece close to the image side and has a first reflecting surface and a second reflecting surface; The part of the parallel light emitted by the eyepiece is reflected by the first reflecting surface to the second reflector, and part of the parallel light is transmitted through the first reflecting surface and reflected by the second reflecting surface to the first reflector; The first reflector continues to reflect the light so that the light enters the left eyepiece tube, and the second reflector continues to reflect the light so that the light enters the right eyepiece tube.

[0005] Preferably, the display comprises an OLED.

[0006] Preferably, the imaging sensor is an infrared sensor or a visible light sensor.

[0007] Preferably, the beam splitter is an isosceles triangular prism having a first reflecting surface, a second reflecting surface, and a bottom surface, wherein the first reflecting surface faces the eyepiece, the second reflecting surface is away from the eyepiece, and the bottom surface is parallel to the optical axis of the parallel light.

[0008] Preferably, the first reflective surface is covered with a first reflective film with a reflectivity of 45%-55%.

[0009] Preferably, the second reflective surface is covered with a second reflective film with a reflectivity of 95%-100%.

[0010] Preferably, both bottom angles of the beam splitter are 45°, and the reflecting surface of the first reflector is parallel to the second reflector, and the reflecting surface of the second reflector is parallel to the first reflector.

[0011] Preferably, the beam splitter, the first reflector, and the second reflector can all be made of glass or plastic.

[0012] In summary, the present invention has the following advantages compared with the prior art: This invention requires only one display, one eyepiece, and one beam splitter to reflect light to the first and second mirrors respectively, forming a dual-channel optical path that allows the user's left and right eyes to observe images simultaneously. This reduces the number of displays and eyepieces required, which helps to lower the overall cost and power consumption of the device. Attached Figure Description

[0013] Figure 1 This is the optical path diagram of the binocular telescope in this invention. Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example 1:

[0015] like Figure 1 As shown, this embodiment provides a binocular telescope, which includes: Imaging sensor 1 is used to sense light reflected from an object and generate an image based on the sensed light. In this embodiment, the type of imaging sensor 1 can be determined according to actual imaging needs. For example, if an infrared image needs to be generated, an infrared sensor is selected for imaging sensor 1; if a visible light image needs to be generated, a visible light sensor is selected for imaging sensor 1. Display 2, which is electrically connected to the imaging sensor 1, is used to display the image generated by the imaging sensor 1; in this embodiment, the type of the imaging sensor 1 can be determined according to the actual imaging effect, for example, OLED (Organic Light Emitting Display) can be selected as the display; Eyepiece 3, which is disposed on the side of the display 2 near the image side, is used to modulate the light emitted by the display 2 into parallel light; Beam splitter 4, first reflecting mirror 5, second reflecting mirror 6, left eyepiece tube 7, and right eyepiece tube 8; The beam splitter 4 is disposed on the side of the eyepiece 3 near the image side, and is used to reflect part of the parallel light emitted through the eyepiece 3 to the first reflecting mirror 5 and part of it to the second reflecting mirror 6. Furthermore, the first reflector 5 continues to reflect the light, allowing the light to enter the left eyepiece tube 7; and the second reflector 6 continues to reflect the light, allowing the light to enter the right eyepiece tube 8; thus, the user's left and right eyes can observe the image through the left eyepiece tube 7 and the right eyepiece tube 8, respectively.

[0016] Therefore, in the binocular telescope structure design of this embodiment, by setting only a display 2, an eyepiece 3 and a beam splitter 4, light can be reflected to the first reflecting mirror 5 and the second reflecting mirror 6 respectively, forming a dual-channel optical path that allows the user's left and right eyes to observe images simultaneously. Compared with the prior art, it can reduce the number of displays and eyepieces, greatly reduce the use of related hardware, and help reduce the overall cost and power consumption. Example 2:

[0017] The only difference between this embodiment and embodiment 1 is that the beam splitter 4 is an isosceles triangular prism, which has a first reflecting surface 41, a second reflecting surface 42 and a bottom surface 43, and both bottom angles are 45°. At the same time, the first reflecting surface 41 faces the eyepiece 3, the second reflecting surface 42 is away from the eyepiece 3, and the bottom surface 43 is parallel to the optical axis of the parallel light. The first reflective surface 41 is covered with a first reflective film with a reflectivity of 45%-55% (preferably 50%), and the second reflective surface 42 is covered with a second reflective film with a reflectivity of 95%-100% (preferably 99%-100%). The parallel light emitted through the eyepiece 3 passes through the first reflective film on the first reflective surface 41 and enters the beam splitter 4 for transmission until it is reflected by the second reflective film on the second reflective surface 42 to form a first reflected beam L1. Part of the light is reflected by the first reflective film on the first reflective surface 41 to form a second reflected beam L2. The optical axes of the first reflected beam L1 and the second reflected beam L2 are parallel and both are perpendicular to the optical axis of the parallel light.

[0018] Furthermore, the reflecting surface of the first reflector 5 is parallel to the second reflecting surface 42, and the reflecting surface of the second reflector 6 is parallel to the first reflecting surface 41. This allows the first reflector 5 to continue reflecting the first reflected beam L1 at a 90° angle, so that the first reflected beam L1 enters the left eyepiece tube 7 at an angle parallel to the parallel light. And the second reflector 6 continues to reflect the second reflected beam L2 at a 90° angle, so that the second reflected beam L2 enters the right eyepiece tube 8 at an angle parallel to the parallel light, so that light can fully enter the tube and ensure that the image observed by the user is clear.

[0019] In this embodiment, the beam splitter 4, the first reflector 5, and the second reflector 6 can all be made of glass or plastic.

[0020] In summary, this invention can reflect light to the first and second reflectors respectively by setting only one display, one eyepiece, and one beam splitter, forming a dual-channel optical path that allows the user's left and right eyes to observe images simultaneously. This reduces the number of displays and eyepieces required, which helps to reduce the overall cost and power consumption of the device.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
