Theoretical analysis and test for off-axis Cassegrain optical antenna
چکیده انگلیسی

By detailed analysis of Cassegrain optical antenna with inclined optical axis, the receiving antenna power and the curve of power attenuation are obtained for different deflection angles. Three-dimensional images which describe the power distribution of the receive laser beam have been obtained. The coupling efficiency of antenna system is obtained from specific experiment. If the deflection angle is less than 0.1519 rad, the coupling efficiency is beyond 80%. In this case, the optical antenna system can be viewed as in alignment approximately. This research will provide a theoretical base and broad application for achieving precise alignment of optical axis in the field of optical communications and three-dimensional laser radar images.
