Abstract

We propose an algorithm for a receiver, which is attached on a moving carrier, to detect the laser beam for free space communication. The characteristic of the receiver is that it can detect the transmitted signal in a large view angle and with a large cross area. We have theoretically calculated the relative detecting light intensity with respect to the incident angle. In addition, the scattering characteristic of a ground glass, which serves as a diffuser, has been studied. Finally, we design a receiver with a view angle larger than 30o. For a special ground glass, the angular tolerance of the receiver is as large as 120 o.
