Laser strobe active night vision method for remote night monitoring

Abstract

The invention discloses a laser strobe active night vision method for remote night monitoring. In the method, a one-frame multi-pulse and multi-door working mode is adopted, in one frame time of exposure of an imaging device, a pulse laser emits a laser pulse sequence, a strobing gate works according to a preset strobing pulse sequence, and the imaging device receives a plurality of target echo signals from a target, therefore, the purpose of light accumulation and signal enhancement is achieved. The invention has good working environmental suitability, and can normally work under the condition of low visibility. Since a long-distance target can be observed at night by using the low-power pulse laser, the cost of the system is greatly reduced, the laser security of the system is improved, and especially the security of eyes is improved.

Description

technical field [0001] The invention relates to the technical field of laser active night vision, in particular to a laser strobe active night vision method for remote night monitoring. Background technique [0002] Long-distance night vision technology is used in maritime resource management, anti-drug and anti-smuggling at sea, maritime search and rescue, high-altitude observation monitoring system for border and coastal defense, intelligent traffic monitoring system, monitoring system for nuclear power plants, oil storage bases and other important places, and forensic monitoring for public security and judicial departments etc. have broad application prospects, especially in severe weather environments. [0003] There are currently four main technologies that can be used for night video surveillance: LED night vision technology, infrared thermal imaging technology, continuous laser night vision technology and distance gating laser night vision technology. [0004] LED ni...
