Abstract

The invention discloses a single lens multispectral imaging optical system and belongs to the technical field of remote sensing. The system specifically comprises a multispectral apochromatic lens, a first beam splitter, a second beam splitter, a doublet lens, a visible light flat-panel detector, an infrared flat-panel detector and a laser flat-panel detector. The first beam splitter reflects visible light, and transmits infrared and laser; the second beam splitter reflects laser and transmits infrared; and the multispectral apochromatic lens, the first beam splitter and the second beam splitter are made of materials of high transmittance from the visible light to a long-wave infrared band, preferably chemical vapor deposition zinc sulfide. The function of performing multispectral imagingby using a single lens is realized, an image from the visible light to the long-wave infrared band can be obtained, and imaging performance is high; the spectrum coverage range is wide; and the system can be widely applied to the remote sensing of the fields of aerophotography, agriculture and forestry, geology and geography, hydrology and marine, and the like.

Description

technical field [0001] The invention relates to a single-lens multispectral imaging optical system, which belongs to the technical field of remote sensing detection. Background technique [0002] The multi-spectral camera is an imaging objective lens made of materials with high transmittance to the imaging band, which forms an optical system with filters, beam splitters, etc., and divides the radiation and reflected beams of the same scene into several bands according to different wavelengths. They are recorded separately and simultaneously to obtain a set of images in different spectral bands of the same scene. [0003] Multispectral cameras are mostly used for aerial photography, and are an important research method in the fields of agriculture, forestry, geology and geography, hydrology and oceanography, as well as an important method for military reconnaissance, and an extremely important remote sensing technology. The multi-spectral imaging optical system is an importa...
