| Abstract: | Optical theory is applied to the design of atmosphere laser communication machine. Optical theory model of transmition and detection of atmosphere laser communication machine is presented.Formula is refined and deduced on semiconductor laser far-off transmitsion,collimating transmission and detection loss of receiving lens. Formula is refined and deduced on collimating laser focal detection airy spot and corresponding centroid operation and centroid estimate. Corresponding optical antenna and spectroscope are designed. Corresponding system precision parameter are designed on optical antenna precision, CCD acquisition precision, communication precision and servo system precision. |
