Wide-spectrum common-caliber TV infrared zoom imaging and laser tracking guiding optical system

Abstract

The invention, which belongs to the technical field of optoelectronic devices, relates to a wide-spectrum common-caliber TV infrared zoom imaging and laser tracking guiding optical system. A front fixation group, a zooming group and a compensation group form a common zooming group of an optical system and thus a common-caliber common-zooming optical path structure is formed. A same target can be locked simultaneously by using a same optical path and the same target is detected and identified simultaneously by using different spectrums from a small view field to a large view field, so that thereaction speed of the optical system is increased substantially, the real-time requirement of the detection is met, and a phenomenon of losing some quickly moving targets by optical path switching isavoided. All optoelectronic devices are integrated into one and visible TV imaging is carried out on the same target by using a same imaging window and the target radiation characteristics, laser tracking and laser height finding functions are detected.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic equipment, and relates to a common-aperture visible television, mid-wave infrared zoom imaging, and laser tracking and guiding optical system. Background technique [0002] With the increasingly complex application environment of modern security detection, higher and higher requirements are put forward for the miniaturization, light weight, comprehensive detection ability, response speed and real-time performance of the imaging optical system. In this context, a multi-band integrated zoom optical system came into being. The zoom optical system can realize fast search and discovery of targets with short focus and large field of view, precise observation and measurement of targets with long focus and small field of view, and track and lock targets by changing the focal length in real time. The wide-spectrum optical system has become an important direction in the development of the optical fi...
