Abstract
In view of the urgent demand high resolution and large field of view on three-line array airborne mapping camera, the paper proposes a new idea which applies monocentric multiscale principle to three-line array airborne mapping camera with high resolution and large field of view (FOV), and gives the design method and design process of optical system. monocentric multiscale optical system is designed, focal length is 70mm, resolution is 0.1m@2Km, and there are four multispectral bands which are panchromatic、R、G、B band. The Base to Height ratio (B/H) is 0.83. The FOV of monocentric multiscale optical system is 80°, and working FOV is 60° which can be extended to 105°. The optical system has excellent imaging quality and successfully solved contradiction between large FOV and high resolution.
