A multi-band integrated sensor optical system

Abstract

The invention discloses a multiband integrated sensor optical system, which comprises a front beam compressing system, a beam splitting flat plate 1 for transmitting medium wave infrared light and reflecting visible light and laser, a beam splitting flat plate 2 for transmitting visible light and reflecting laser, an infrared optical system, a laser ranging system and a visible light optical system, which are arranged in sequence from an object side to an image side in the optical axis direction. The infrared optical system, the laser ranging system and the visible light optical system share the front beam compressing system, and form an infrared channel, a laser ranging channel and a visible light channel respectively; and the three channels can rotate around the Z axis for 360 degrees torealize azimuth scanning and detection, and can rotate around the X axis for 360 degrees to realize pitch scanning and detection, so that panorama coverage is realized. The multiband integrated sensor optical system is compact in structure, good in optical axis uniformity, high in pointing accuracy and easy in installation and adjustment, covers three bands of visible light, infrared and laser, realizes medium wave infrared and visible light imaging, and effectively improves performance of photoelectric detection equipment.

Description

technical field [0001] The patent of the invention belongs to the field of optical technology, and specifically relates to a multi-band integrated multifunctional sensor optical system. Background technique [0002] In the field of national defense and military applications, it is necessary to quickly perceive the surrounding situation all day long under different environmental conditions, and to track and accurately measure the target in real time.
