    • Abstract
  • According to the technical requirements of the high resolution TV seeker, the system's optics parameters were calculated and the focusing range was optimized. F number of the optical system was defined. An optical zoom system with focal length of 40 mm ~ 152 mm and the F number of 3.5 was designed. The design results show that throughout the zoom process the values of the MTF at 106 lp/mm reach or close to 0.4, the image plane is stable and the image quality is good.
