Abstract

The invention provides an optical imaging system for visible light waveband, medium-wave infrared waveband and long-wave infrared waveband. The optical imaging system mainly solves the problem that an existing multi-spectrum camera is heavy in structure and complicated in optical system. The optical imaging system for visible light waveband, medium-wave infrared waveband and long-wave infrared waveband comprises a first reflection mirror, a second reflection mirror and a third reflection mirror, wherein the first reflection mirror is used for reflecting the visible light waveband, the medium-wave infrared waveband and the long-wave infrared waveband, the second reflection mirror is used for reflecting the visible light waveband and the medium-wave infrared waveband and transmitting the long-wave infrared waveband, and the third reflection mirror is used for transmitting the visible light waveband and the medium-wave infrared waveband and reflecting the long-wave infrared waveband. The optical imaging system for the visible light waveband, the medium-wave infrared waveband and the long-wave infrared waveband is light in structure, few in optical devices, fine in imaging quality, small and high in engineering realizability and is integrated with multi-spectrum detection.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, and relates to a three-band optical imaging system of visible light, medium-wave infrared and long-wave infrared, and in particular to a multi-spectrum light and small detection optical system suitable for space environment and used in aerospace non-cooperative target detection systems. Background technique [0002] With the development of optical technology and electronic technology, the requirements for the technical indicators of space optical payloads are getting higher and higher, and the demand for light and small, high-resolution, multi-band detection optical cameras in the aerospace field is increasing. In order to achieve the technical indicators of high-resolution and multi-band detection, it is usually to design three independent optical cameras suitable for specific bands. The optical path connected to the detector constitutes three independent optical cameras. At night, the m...
