| 摘 要： | 依据高分辨率电视图像导引头瞬时视场和作用距离的要求，结合选定相机的光敏面尺寸等，计算并确定了光学系统的焦距范围，根据光学系统分辨率以及结构尺寸等要求，确定了光学系统的F数，选择机械补偿法、负组补偿的变焦结构，给出焦距分配过程，最后，给出了焦距为40 mm～152 mm、F数为3.5的连续变焦光学系统的设计结果。设计结果表明:在整个变焦过程中，光学系统的传递函数值在106 lp/mm处达到或接近0.4，像面稳定，像质良好。

| 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. |
