Abstract

The invention provides a visible light-short wave infrared-medium wave infrared-long wave infrared four-waveband optical system which solves the problems that existing single-waveband equipment can detect limited information and cannot meet the requirement for more comprehensive and more accurate target detection. The system comprises a main reflecting mirror, a secondary reflecting mirror, a first folding shaft mirror, a first spectroscope, an infrared focusing mirror group, a second spectroscope, a visible light channel subsystem, a short-wave infrared channel subsystem, a medium-wave infrared channel subsystem and a long-wave infrared channel subsystem, the secondary reflecting mirror divides the light beam reflected by the main reflecting mirror into two paths, namely a visible light-short wave infrared light beam and a medium wave infrared-long wave infrared light beam, a visible light-short wave infrared light beam is divided into two paths after passing through the first foldingshaft mirror and the first spectroscope, and the two paths enter the visible light channel subsystem and the short wave infrared channel subsystem respectively. A medium wave infrared-long wave infrared light beam is divided into two paths after passing through the infrared focusing lens group and the second spectroscope, and the two paths respectively enter the medium wave infrared channel subsystem and the long wave infrared channel subsystem.

Description

technical field [0001] The invention relates to a four-band optical system, in particular to a visible light-short-wave infrared-medium-wave infrared-long-wave infrared four-band optical system. Background technique [0002] The visible light optical system can receive objects that emit light by themselves or objects that reflect light outward after being illuminated by other light. Its performance at night and low-light conditions is greatly reduced or even unusable. In addition, it is susceptible to environmental interference. Difficult to observe when obstructed. The infrared optical system receives the thermal radiation of the target itself. No matter it is day or night or the environmental visual conditions are poor, the infrared optical system can realize observation. Compared with the visible light optical system, the infrared optical system can identify more safely and covertly. target or camouflaged target. [0003] With the continuous improvement of target camouf...
