Abstract
A linear four element adaptive heterodyne optical receiver array employing semiconductor lasers is described. The array adaptively adjusts the phase of each subaperture IF signal to correct for wavefront tilt and distortion and non-uniform optical and RF path delays across the array by phase-locking each channel to a reference channel.
