Abstract: Wireless laser communication is a new form of communication in which information is promulgated through space and the laser is used as carrier wave. The ATP technology with highprecision and highautomation is one of the key techniques, which can be related to the success of creating the space optical communication link and the quality stand of communication. It is analyzed the fourquadrant detection technology and area array CCD detection technology, gave the specific calculation algorithm of the spot center and dew the relevant conclusions through simulations. The simulation results show that, for QD detection, in order to restrain the background light can be used for audio modulation; CCD array detector, using spatial filtering to eliminate the influence of background light, and then laid the groundwork for the establishment of optical communication link.
