Design and Demostration of A 10.6 μm Auto-tracking and Pointing Optical Antenna

Following the demands of the optical antenna of the wide-band digital communication lightwave system (WDCLS) and detailed computation,an off-axis catadioptrical optical antenna with the features of combined transmitting and receiving,auto-acquiring,tracking and pointing is designed.The method and experience of tuning the optical system and the results of the practical field experiments are also presented.The results of the experiments showed that the optical antenna operates very well.
