Stepping staring type optical system for resonance lens compensation type area array CCD (charge coupled device)

Abstract

A stepping staring type optical system for a resonance lens compensation type area array CCD (charge coupled device) is used for the field of infrared photoelectric detection and tracking. A streaking phenomenon existing in an alarming detection process of the existing area array infrared CCD optoelectronic device is avoided. A front lens subassembly, a resonance lens subassembly and an infrared area array CCD subassembly are coaxially placed in the system from left to right, wherein the resonance lens subassembly comprises an angle measuring element, a resonance voice coil motor and a resonance lens; the angle measuring element, the resonance voice coil motor and the resonance lens are integrally assembled in a linear installation mode; the deflection angle of the resonance lens can be precisely outputted by the angle measuring element; the front lens subassembly consists of a plurality of lenses; the lenses are placed coaxially; the front lens subassembly has an optical path compression and collimation function; sceneries in a view field can be compressed into a range which can be received by a CCD target surface; and the resonance lens subassembly is arranged at a position between the front lens subassembly and the infrared area array CCD subassembly and is positioned at a narrowest position of a light beam in the optical system.

Description

technical field [0001] The invention relates to a resonant lens compensation type area array CCD step staring optical system. The optical system uses a resonant lens to solve the problem of image smearing caused in the scanning imaging process of an area array infrared CCD, and is applied to the field of infrared photoelectric detection and tracking. Background technique [0002] The main performance index requirements of infrared photoelectric detection and tracking equipment include detection distance, effective airspace warning scanning time period, target tracking judgment sensitivity, etc. The general feature of photoelectric countermeasure equipment is to first use infrared band detectors or visible light band TVs to realize the discovery, identification and tracking of targets, and then start jamming or damaging lasers to interfere or destructively destroy targets in specific bands. In this process, the tracking device generally adopts stealth passive receiving, and t...
