In this paper, in order to track and measure the long-distance target, a continuous zoom optical system with a diameter of 400mm and focal length of 1000mm-4000mm is designed. The imaging quality evaluation of optical system is mainly carried out from the following five aspects: field curvature, distortion, transfer function MTF of optical system, energy concentration and spot array. Through the simulation calculation of image quality, the performance of optical system meets the requirements of clear imaging. |
