| Abstract: | The free-space laser communication is a new communication technology and a combination of optical fiber communication and wireless communication,in which the high-accuracy wide-band laser acquisition,alignment and tracking(APT) are the key techno-logies.The system architecture and its working process of APT are discussed,and the key techno-logies are introduced.The acquisition methods,tracking and pointing accuracy are further analysed,and an optimal value is given by the error analysis. |
