An Infrared Search and Track Integrated Optical Imaging System

Abstract

The invention discloses an infrared searching and tracking integrated optical imaging system. A turntable comprises a telescope lens assembly, a fly-back swing mirror and a focusing lens which are sequentially arranged from an object space to an imaging space; the telescope lens assembly is used for collecting infrared radiation of the object space, compressing the caliber of an incident beam and emitting the incident beam in a parallel light form; the fly-back swing mirror is used for swinging back and forth along with rotation of the turntable in a searching state, stabilizing an image on a staring detector after infrared radiation of the object space collected by the telescope lens assembly is processed on the focusing lens, stopping swinging in a tracking state, directly imaging on the staring detector after infrared radiation of the object space collected by the telescope lens assembly is processed on the focusing lens, and tracking under driving of the turntable; and the focusing lens is used for focusing parallel light emitted by the fly-back swing mirror on a focal plane of the staring detector for imaging. The system is simple in structure, can simultaneously realize searching and tracking, and greatly facilitates users.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an infrared search and tracking integrated optical imaging system. Background technique [0002] The infrared search and track system is an important target detection device, which can give early warning to low-altitude and ultra-low-altitude targets and determine the coordinates of the target. It can realize rapid imaging on the infrared detector in the horizontal 360° airspace. It has very broad application value in the fields of air surveillance, low-altitude air defense, and space early warning. [0003] However, the existing infrared search and track system is two separate systems, which cannot realize search and track at the same time, causing unnecessary troubles to users. Contents of the invention [0004] In view of the above analysis, the present invention aims to provide an infrared search and tracking integrated optical imaging system, which integrates infra...
