| 摘 要： | 设计一款应用于多发射天线多接收天线自由空间激光通信系统中的折射式光学接收天线。天线焦距120.02 mm，相对孔径1∶1.13，工作波长为850 nm，波长范围覆盖820 nm ~880 nm，在50 lp/mm频率处0视场的MTF为0.5。接收天线可以在发射天线移动48 mm范围内利用光敏面直径为0.5 mm的雪崩光电二极管（APD）接收3 mrad发散角的光信号。该天线由两组、共4片球面透镜组成，结构简单，可实现对运动式发射天线的光信号的接收。

| Abstract: | A refractive optical receiving antenna that was used in the multi-transmitter multi-receiver free space laser communication system was designed. The focal length of the antenna was 120.02 mm and relative aperture was 1∶1.13. The antennas working wavelength was 850 nm and wavelength range was 820 nm ~880 nm. The MTF of 0 field of view was 0.5 at the spatial frequency 50 lp/mm. In the transmitting antenna movable range of ±48 mm, the receiving antenna could receive the optical signal of 3 mrad divergence by using the avalanche photo-diode(APD) with 0.5 mm diameter of photosensitive surface. This refractive optical receiving antenna was composed of 4 spherical lenses, was simple in configuration, and could receive the optical signal from movable transmitting antenna. |
