  • In order to complete recognition and detection tasks of the aircraft seeker, a high precision, miniaturization of the zoom optical system is designed. Targets are searched and identified at short focal length, wide field, and recognized at long focal length, narrow field. The mechanical compensation method is selected using three kinds of common optical materials. At the location of the long focal length, combinatorial design of the front group and the zoom group can make the system compact, and meet seeker miniaturization requirements. The zoom optical system with optimization focal length about 12.9010.25~2.592.07 and lene tube length only 174 mm is designed by using the CODEⅤ optical design software. For the each focal length and each field of view, the average MTF is 0.695, and tested result is 0.562 at 50 lp/mm, which can meet performance requirements of the system.
