A Common Aperture Active and Passive Imaging Detection System

Abstract

The present invention is a common-aperture active and passive imaging detection system, which is composed of a laser source, a transmitting and receiving optical system, a spectroscopic system, and an image acquisition, processing and display system; it is placed in a casing, and the laser source is located at the rear end of the casing The transmitting and receiving optical systems are placed at the front of the housing; the beam splitting system is placed at an angle of 45° to the optical axis, parallel to the transmitting-receiving beam splitter and the line connecting the two centers is perpendicular to the optical axis; the image acquisition, processing and display system is placed behind the housing It can achieve real-time and rapid active and passive imaging of scenes containing targets with "cat's eye" effect through the shared receiving optical system, and extract target features through active and passive image processing to determine the position of the target. The system is novel in structure, compact and portable, stable in performance, strong in adaptability, good in anti-interference performance, and high in image signal-to-noise ratio, and can be applied to security protection, anti-terrorist operations, monitoring work, etc. The invention has wide practical 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 involving integrated information processing of light, machine, electricity and calculation. The system is mainly used to detect optical systems such as optical sights, cameras, and telescopes with a "cat's eye" effect, and determine the location of the threat. It belongs to the field of laser imaging detection technology. (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, the threat is increasing. In order to accurately, promptly and quickly detect and annihilate enemy snipers, anti-sniper detection systems with multiple mechanisms have emerged, including infrared detection systems, acoustic detection systems, and laser detection systems. The molded products based on infrared detection and ac...

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 obtained in complete darkness

The advantage of active imaging is that it is less affected by the environment, for example: it can obtain target images in complete darkness, and can obtain target images through fog or mesh obstacles; the disadvantage is that it consumes a lot of power and has poor concealment
