AI Technical Summary

Technical Problem

Existing day/night sights have poor image quality in bright daylight, suffer from overexposure and stray light interference, have complex switching mechanisms and unstable zero position, are cumbersome to operate, and are difficult to meet the tactical requirements for rapid response.

Method used

Employing a common-path optical system and a precision mechanical switching mechanism, and through a physically isolated switching design of a low-light detector, it achieves high-definition integrated fusion of visible light direct-view mode and low-light digital mode. Combined with Hall elements and magnets, it enables non-contact sensing and automatic power-on/off, ensuring optical axis consistency and zero-position stability.

Benefits of technology

Achieve pure optical direct-view imaging during the day, eliminating strong light overexposure and stray light interference; maintain high-sensitivity night vision imaging capability at night; simplify operation procedures; reduce power consumption; extend detector life; and ensure switching zero-position stability and high-definition imaging quality.

Abstract

This application relates to the field of optoelectronic device technology, and provides a switchable day / night sight, including a front housing group, a middle housing group, and a rear housing group arranged along the optical axis. The front housing group includes an objective lens group; the middle housing group includes a prism group, a mechanism support, a low-light detector, a display screen, a processing board, and a switching mechanism; the rear housing group includes a relay lens group and an eyepiece group; the switching mechanism includes a fixed shaft, a large rotating shaft, a small rotating shaft, a positioning pin, a spring, a limiting protrusion, and a handle; wherein, the mechanism support is fixedly connected to the large rotating shaft, the low-light detector is mounted on the mechanism support, and the handle drives the large rotating shaft and the mechanism support to rotate around the axis of the large rotating shaft through the small rotating shaft, so as to drive the low-light detector to enter or exit the optical path between the objective lens group and the prism group. Through the coordinated cooperation of a common-path optical system, a precision mechanical switching mechanism, and electronic reticle superposition, the fusion of visible light direct-view mode and low-light digital mode is achieved, solving the problem of poor daytime imaging quality in traditional day / night sights.
