Abstract

For Free Space Optical Communication (FSOC) systems, employed on moving platform or communicating with a moving remote terminal, the quality of the communication channel strongly depends upon the tracking performance. In these systems quadrant Position Sensitive Detectors (PSD) are commonly used for beam tracking. This paper presents the results of significantly improved performance in acquisition and tracking of the FSOC system using a custom made 8-segments PSD and minimizing the tracking spot size on the detector.
