Abstract
In view of urgent demand high resolution and large field of view on three-line array airborne mapping camera, the paper proposes an airborne mapping camera optical system with large field of view and high resolution, which consists of single telecentric lens, RGB multispectral prism and field splicing prism. In order to solve RGB multispectral splitting problem in system, a new multispectral splitting prism based on a close distance confocal plane linear array sensor is proposed, which successfully solves RGB multispectral splitting problem of confocal plane linear array sensor with a close distance (B band and G band are only 4 pixels apart, and G band and R band are 2.2mm apart). The telecentric optical system is designed, focal length is 130mm, field of view (FOV) is 77° (working field of view is 60°), and image elecentricity is less than 0.1° across full field of view. There are four multispectral bands which are panchromatic, R, G, B band. The optical system has excellent imaging quality and compact structure.
