Light intensity modulation interference method and system for precisely pointing laser interference

Abstract

The invention discloses a light intensity modulation interference method and a system for precisely pointing laser interference, and the method comprises the steps: enabling a camera module and a distance measurement module to be started to obtain the precise position of a target camera, enabling a laser pointing control module to control a laser to adjust the emergent angle according to an angle deviation value, and enabling the laser to adjust the zooming according to a distance value, and meanwhile, modulating the laser, and enabling laser beams emitted by the laser to continuously irradiate the lens of the target camera, so that the target camera is interfered. Therefore, the system has the characteristics of high interference precision, small system size, strong concealment and high reliability. In addition, the system is provided with two sets of lasers, the lasers can be switched according to the daytime environment and the night environment, invisible light is used for interference at night, and good concealment is achieved.

Description

technical field [0001] The invention relates to the technical field of laser interference, in particular to a light intensity modulation interference method and device for precisely pointing laser interference. Background technique [0002] In recent years, with the development of science and technology, the popularity of cameras has become higher and higher, which has greatly promoted social security and stability, and played a major role in protecting people's property safety. However, the rapid popularization of cameras has also brought about the problem of abuse. Some criminals can use cameras to spy on other people's privacy; cameras are placed in key positions to monitor police and other personnel. This has caused serious harm and challenges to personal privacy, property safety and police execution of official duties. [0003] At present, the relevant technologies of jamming cameras are gradually developing, and there are some mature jamming devices on the market, but...
