We present a design for an optical data communications receiver-transmitter
pair based on the holographic correction of a large diameter, poor-quality
, reflecting primary mirror. The telescope has a narrow bandwidth (<0.1 nm)
with good signal frequency isolation (>60 dB) and is scalable to meter-cla
ss apertures. We demonstrate the correction of a reflector telescope with o
ver 2000 waves of aberration to diffraction-limited operation, capable of h
andling data transmission rates up to 100 GHz. (C) 1999 Optical Society of
