The structure and characteristics of laser semi-active seeker and its optical system were introduced in the paper.According to the general technical requirements of semi-active laser seeker,the key parameters of optical system were analyzed and calculated,the structure of optical system is selected.The aberration and spot requirements of optical system of laser seeker are analyzed.A catadioptric optical system of semi-active laser seeker is designed.The simulation results show that in the whole linear fields of view the spot diameter has no change and the energy distribution was uniform,the stability of spot diameter in the instantaneous fields of view are better than 2 %.The optical design satisfied with the requirements and lays a good foundation for the next step of seeker design.
