Simulation study of an adaptive phase alignment system for optical heterodyne communications under misalignment conditions.

Simulation study of an adaptive phase alignment system for optical heterodyne communications under misalignment conditions.

A postphotodetection adaptive phase alignment system using an aperture array of photodetectors is presented to reduce the signal loss in an optical (free-space) heterodyne receiver resulting from wavefront misalignment (tilt) on a satellite platform. This paper compares two kinds of rectangular aper...
