Remote laser night-viewing device

Abstract

The invention discloses a remote laser night-viewing device. The invention adopts a technical scheme that: the remote laser night-viewing device comprises a shell and a laser illuminator arranged in the shell, wherein a telephoto lens and an integral camera are fixedly arranged in the shell; a main controller is also arranged in the shell; and the main controller can control the zoom focusing of the integral camera and the telephoto lens, the video intelligent switch between the integral camera and the telephoto lens, and the size of laser spots. The device takes full use of the advantages of large remote light transmission and good image quality of the telephoto lens, embodies the characteristics of wide close-distance observation range and clear images of the integral camera, and greatly reduces the production cost on the premise of realizing remote night-viewing monitoring.

Description

technical field [0001] The invention relates to a laser night vision device, in particular to a low-cost long-distance laser night vision device. Background technique [0002] In the monitoring field, people pay more and more attention to the monitoring under the condition of no light at night. At present, the more mature method is to use infrared laser illumination. However, the shortcoming of this method is that it can only realize close-range night vision monitoring, and cannot realize the night vision monitoring effect beyond 200 meters. The emergence of laser night vision technology makes up for this defect. Using infrared laser lighting technology, combined with a telephoto zoom lens, it can realize night vision monitoring within 5 kilometers. However, the telephoto lens used for monitoring requires high manufacturing precision, expensive lenses, and low annual sales, which make it expensive. Generally, the price of lenses above 600mm for monitoring is tens of thou...

Problems solved by technology

However, the telephoto lens used for monitoring requires high manufacturing precision, expensive lenses, and low annual sales make it expensive.

Generally, the price of a lens above 600mm for monitoring is tens of thousands or even hundreds of thousands, which greatly restricts the application and promotion of laser lighting technology.
