Optical receiving antenna based onmovable transmitting antenna

More Information
  • 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 antenna-s 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.
