Gun sight optical system

Abstract

The invention discloses a gun sight optical system. The system comprises a white light objective lens assembly, a light splitting and image transferring assembly, a light splitting prism assembly and an eyepiece assembly which are sequentially arranged in the direction from the object side to the image side, a low-light objective lens assembly arranged below the light splitting and image transferring assembly, as well as an infrared objective lens assembly arranged below the white light objective lens assembly. The white light objective lens assembly, the light splitting and image transferring assembly, the light splitting prism assembly and the eyepiece assembly are sequentially arranged in the direction from the object side to the image side, the infrared objective lens assembly is arranged below the white light objective lens assembly, the low-light objective lens assembly is arranged below the light splitting and image transferring assembly, the white light objective lens assembly and the low-light objective lens assembly share an aperture, a white light image can be directly observed through the eyepiece assembly, and a low-light image and an infrared image can be obtained by observing a display screen assembly through the eyepiece assembly; the rear working distance of a white light objective lens is effectively compressed through the light splitting and image transferring assembly, and the purpose of system device miniaturization is achieved.

Description

technical field [0001] The present disclosure generally relates to the technical field of optical system design, and specifically relates to a gun sight optical system. Background technique [0002] At present, the white light, low light, and infrared three-light gun sight optical system usually consists of white light, low light, infrared lenses, their respective detectors, eyepieces, and display screens. The scene is imaged on the detector through the distributed three-light lens, and then the image is processed. , to generate a single-light image or a fusion image, and the human eye observes the display screen through the eyepiece to obtain an image of the scene. [0003] The advantage of this type of product is that it can be used around the clock and can still work normally at night. Switching between different bands has the effect of identifying camouflaged targets. However, due to the sub-caliber design, each band needs a corresponding lens. The gun sight system is bu...

Problems solved by technology

[0003] The advantage of this type of product is that it can be used around the clock and can still work normally at night. Switching between different bands has the effect of identifying camouflaged targets. However, due to the sub-caliber design, each band needs a corresponding lens. The gun sight system is bulky and not conducive to carrying. And through the white light image as the eyepiece to observe the display screen, compared with the traditional white light direct aiming, the image seen is limited by the exposure time of the detector, information processing time, frame rate of the display screen and the resolution of the detector and display screen. There is smear and a certain delay, and the resolution drops

Therefore, we propose a gun sight optical system to solve the above-mentioned problems of bulky system, inconvenient portability and poor image resolution
