Abstract
Laser ranging is a crucial issue for collimation zoom optical systems, in order to make sure the beam alignment adapt to the aperture, the spatial divergence angle of the laser beam should be improved. In this paper, a collimation zoom optical system was designed based on the principle of non-focal magnification collimation and direct beam expansion. The optimized operation function DMVA is input into the Zemax simulation system to control the image height, and the curvature, thickness and air space of each lens of the system are optimized to reach the index requirements. The results of the optical track simulation shows that the energy distribution is uniform and non-dispersive. The collimation zoom system, four-group telescope is used instead of the group telescope structure, which have simple structure, the design of cam curve ensure the boresight of optical axes meets the design index, that reduce the ranging error efficiently. The accuracy error of the instrument is less then 0.5 m when field ranging is 10 km.
