Integrated laser night vision device with single lens

Abstract

The invention relates to a night vision device, in particular to an integrated laser night vision device with a single lens. The integrated laser night vision device with a single lens comprises a collimator mirror, a beam expander, a prism, a replication prism, an optical glass window, a secondary refraction lens and a camera imaging device, wherein a laser optical fiber is fixed on an optical fiber support; the optical fiber support is sequentially connected with the collimator mirror, the beam expander, the prism and the replication prism; a post-focusing lens is connected with a front focusing lens; the front focusing lens is connected with an one-time reflex prism and the optical glass window; the front focusing lens is connected with the secondary refraction lens; and the secondary refraction lens is connected with an optical filter and the camera imaging device. The integrated laser night vision device realizes the ultra-remote video monitoring in the security field, enables a camera and a laser device to utilize the same lens and realizes the purpose of remote monitoring by adopting a novel reflex lens, an optical structure and an electronic circuit, wherein the optical structure and the electronic circuit are matched with the novel reflex lens.

Description

1. Technical field: [0001] The invention relates to a night vision device, in particular to a single-lens integrated laser night vision device. 2. Background technology: [0002] Existing laser lighting night vision monitoring system currently on the market is a dual-lens device that adopts a combination of a camera and a laser illuminator. It is a monitoring system for laser lighting realized by controlling the focal length of the camera and controlling the projection angle of the laser illuminator. However, this kind of monitoring system requires the operator to be able to use the control host very skillfully, and the operator needs to control the camera and the laser lighting device separately to achieve the best display effect, and the sensitivity of the laser lighting device of this monitoring system is relatively poor. The laser projection angle for the best imaging effect is difficult to adjust, resulting in reduced operability of the entire system. There are also s...

Problems solved by technology

Although this system solves the problem of step-by-step adjustment of cameras and laser illuminators to a certain extent, this monitoring system is still composed of cameras and laser lighting devices; Deviation, the final clear image still needs fine-tuning by the operator to achieve, and both the camera and the laser need to use their own lens, not only the manufacturing process is complicated, the volume is large, and the production cost is also high
