Paper Abstract

The simulation and realization of a miniaturized optical terminal with direct acquisition, direct and homodyne tracking modes and homodyne data transmission are presented. The miniaturized receiver head and the frontend electronics, with its sophisticated signal processing capabilities, combine the tasks of partner-terminal acquisition, direct tracking, homodyne tracking and homodyne data detection. Various pointing, acquisition and tracking (PAT) strategies have been experimentally verified in an optical free space test-bed. A complex link-simulation was developed enabling performance evaluation of the receiver head. Simulation results for direct spatial acquisition and pseudo 4-quadrant tracking are shown. Our technique eliminates the need for additional acquisition hardware like beacon laser and CCD camera.
