Long-wave infrared and visible light common-aperture composite imaging camera and system

Abstract

The invention provides a long-wave infrared and visible light common-aperture composite imaging camera and system. The camera comprises an optical lens, which comprises a front lens group, a spectroscope, a visible light path lens group and a long-wave infrared light path lens group which are sequentially arranged along a light path, wherein the visible light path lens group is arranged on a light path of the visible light, and the long-wave infrared light path lens group is arranged on a light path of the long-wave infrared light; a visible light sensor arranged on the imaging side of the visible light path lens group and used for receiving the light transmitted by the visible light path lens group and generating visible light imaging information; and a long-wave infrared sensor arranged on the imaging side of the long-wave infrared light path lens group and used for receiving the light transmitted by the long-wave infrared light path lens group and generating long-wave infrared light imaging information. According to the technical scheme, the visible light sensor and the long-wave infrared sensor can have the same view field, so that all-day target observation and image acquisition are realized.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to a long-wave infrared and visible light common-aperture composite imaging camera and system. Background technique [0002] When observing the earth at high altitude, it is usually hoped to obtain more information in a larger field of view in a short period of time. The airborne camera has mature technology for visible light sensors and can obtain high-resolution images of the target. The details of the target are rich, but at night Or the imaging quality in bad weather is poor; the long-wave infrared sensor performs imaging by detecting the infrared radiation characteristics of the target, and has the characteristics of strong anti-interference ability and all-weather detection. The good complementarity of long-wave infrared and visible light composite imaging can effectively obtain richer image information and achieve all-weather high-resolution imaging. [0003] The existing v...

AI Technical Summary

Problems solved by technology

[0003] The existing visible light and infrared composite imaging usually uses two independent cameras for sub-aperture imaging, which has a complex structure, large volume and mass, and is not easy to apply; the current visible light and infrared common aperture composite imaging camera is designed based on the Cassegrain system. The instantaneous field of view of the detector is inconsistent with the instantaneous field of view of the visible light detector, resulting in the subsequent need for complex correction and fusion algorithms before the image can be used
