The Optical Design Of Space-borne Multi-spectral Camera

In recent years,multi-spectral imaging technology in various application areas have a wide range of development,due to multi-spectral features,to identify the background of the complex can clearly identify the target object and the background, making the application of this technology in optical instruments in aerospace, water survey, farms, military aspects of a good play, in order to attract a growing number of scholars have joined the multi-spectral imaging technology research team in the aerospace field, multi-spectral imaging technology is often used as a remote sensing platform to detect on the ground in this area spaceborne multi-spectral camera has great potential and prospects for development. As is to be designed to carry the satellite multi-spectral camera, so the camera’s lightweight multi-spectral camera will become the trend of development in the future.Applications and prospects for development of spaceborne multi-spectral camera, the corresponding optical system, the system can clear the400-1000nm spectral range imaging, a focal length of280mm, relative aperture of1/3.5, fullangle3°. High image quality of the design results to meet the actual needs of the alignment of the processing requirements, moderate, and can provide a reference for the design of such multi-spectral camera.
