Abstract

Space Laser communication is a new technology in recent years of optical communications, optical antenna is a communications front receiving system, compose of the optical antenna receiver, optical fiber coupling lenses. Optical antenna to receive as much as possible the signal light from the target of free space, In this paper, 10.6μm wavelength of infrared light for communication wave, we use spherical mirror and aspheric lens combination of the system, Design of large diameter concave mirror to collect more laser energy, After another spherical convex mirror reflection again to aspherical lens, then coupled into the fiber. The aspheric lens can be a good feature to correct aberration, so this design has less transmission loss and high coupling efficiency. Using Zemax software, we setting reasonable energy analysis and image quality evaluation, design spherical mirrors and aspherical refractive lenses optical system, has good optical performance and economy, can be apply on the atmospheric Laser communication the receiving device.
