Description
Technical Field
The utility model relates to the technical field of aiming devices for guns, in particular to an infrared and infrared point fusion aiming system which is compact in structure, available in day and night, high in light transmittance and long in endurance time.
Background
The red point sighting telescope is also called a reflection sighting telescope and also called an inner red point, and is an optical sighting telescope without magnification. Because the light spot of the incident eye in the red point sighting telescope is always balanced with the red point sighting telescope, even if the eye is not on the central axis of the red point sighting telescope, the eye can accurately aim through the red point, and the shooting accuracy during high-speed movement or body shaking can be improved, therefore, the red point sighting telescope is widely used for military firearms and even head-up displays of fighters in various countries.
The traditional red point sighting telescope can only be used in bright environments in daytime or at night, and targets cannot be clearly seen in night and dark environments, so that the sighting effect is poor, and the technical and tactical exertion is seriously affected. Therefore, a red point sighting telescope combining night vision and white light is present, but because a red point light path and a night vision pattern light path are required to be simultaneously arranged and then respectively incident on a curved reflector for fusion and collimation, the size and the volume of the existing fusion sighting system are large, and the exposure risk and the load are increased. Therefore, in the prior art, a prism with a semi-transparent semi-reflective film is arranged between a curved mirror and an eye point of a main optical axis of a sighting telescope, a red point light source and a night vision display unit are arranged on two sides of the prism, are fused through reflection and transmission of the prism, and then are incident on the curved mirror to be collimated and enter human eyes through the prism. According to the technical scheme, the prism is used for turning the light path, so that the size of the fusion aiming system can be shortened, and the whole volume and the weight can be reduced. However, since the prism is disposed in the main optical axis of the sighting telescope, natural light is transmitted through the curved reflector and the night vision image is reflected by the curved reflector, and then the natural light needs to be transmitted through the prism again to enter the human eye, and the semi-transparent and semi-reflective film of the prism can seriously reduce the light transmittance, so that the definition of a target in the process of remotely watching the sighting telescope is affected, and the volume and weight of the prism are relatively large, so that the volume and weight of the fusion sighting system are still too large. Although night vision can overcome the problem of target definition caused by lower light transmittance of the prism by increasing the brightness of the night vision display unit, larger brightness can cause increased power consumption to affect cruising. In addition, in the prior art, the prism is arranged on one side of the main optical axis of the sighting telescope, the inclined light splitting sheet is arranged on the main optical axis of the sighting telescope, meanwhile, the red point light source and the night vision display unit are arranged on two sides of the prism, and then the reflecting mirror and the lens group thereof are arranged behind the prism, so that the red point and the night vision image are incident into the light splitting sheet through the reflecting mirror and the lens group after being fused with the prism, and enter human eyes after being reflected again through the light splitting sheet, and although the light transmittance of the prism with the semi-transparent and semi-reflective film is improved, the multi-introduced light splitting sheet, the reflecting mirror and the lens group increase the complexity, the weight and the volume of the structure, and weaken the improvement of the light transmittance.
