System for detecting active imaging and passive imaging of common aperture

Abstract

The invention relates to a system for detecting active imaging and passive imaging of common aperture, and the system comprises a laser source, an emitting and receiving optical system, a light splitting system and an image acquisition, processing and displaying system; the system is arranged in a shell, the laser source is arranged at the back end of the shell, the emitting and receiving optical system is arranged at the front end of shell; the light splitting system is arranged at an angle of 45 degrees with an optical axis and parallel to an emitting-receiving spectroscope, and the line of centers of the emitting-receiving spectroscope and the light dividing system is vertical to the optical axis; the image acquisition, processing and displaying system is arranged at the back end of the shell (close to the right side); the system can use a common receiving optical system to realize active imaging and passive imaging rapidly in real time for a scene including a target with 'cat eye' effect, extract target features of active image processing and passive image processing and determine the orientation of the target. The system has the advantages of novel structure, compact and portable property, steady performance, strong adaptability, good anti-interference property and good image signal-to-noise ratio. The system can be applied to security, anti-terrorist operations, monitoring and the like, and has wide application value and application prospect.

Description

(1) Technical field [0001] The invention relates to an imaging device, in particular to a common-aperture active and passive imaging detection system for integrated information processing of light, machine, electricity and calculation. The system is mainly used to detect optical systems such as optical sights with "cat's eye" effects, cameras, and telescopes, and to determine the location of threats. The invention belongs to the technical field of laser imaging detection. (2) Background technology [0002] With the improvement of the range, accuracy, and power of sniper rifles, the emergence of high-performance sighting equipment, and the well-trained snipers, their threats are increasing day by day. In order to accurately, timely, and quickly find and destroy enemy snipers, anti-sniper detection systems with various mechanisms have emerged as the times require, mainly including infrared detection systems, acoustic detection systems, and laser detection systems. Among them...

Problems solved by technology

The advantage of the passive imaging system is that it is not easy to be detected by the other party because there is no autonomous light source, and the energy consumption is relatively low, etc.; the disadvantage is that it is greatly affected by the environment, for example: the target image cannot be o
