Design on Optical Lens of Three-linear Tridimensional Mapping Camera
三线阵立体测绘相机光学镜头的设计

In order to improve thepositioning accuracy of mapping system, a design on optical lens of transmission semi-telecentric beam path in image space was expounded, and assembly method based on DFT(Design For Test) of single lens suit and whole optical lens was expounded. The test results indicated that the MTF of optical lens referred in this paper was 0.45(@77lp/mm); the ground resolution power was 5m; the distortion was 3/10000. The test results indicated that the each parameter satisfited user’s qualification.
