Claim 10:
11. A method comprising:
providing outgoing optical signals for transmission by a monostatic optical terminal using multiple transmit channels of multiple optical channels;
providing incoming optical signals obtained by the monostatic optical terminal to multiple receive channels of the multiple optical channels;
for each optical channel, using a polarization rotator and a half waveplate to adjust a polarization of the outgoing or incoming optical signal propagating in one direction in the optical channel and to maintain a polarization of another of the outgoing or incoming optical signal propagating in an opposite direction in the optical channel;
using a polarization beam splitter/combiner to combine the outgoing optical signals into a combined outgoing optical signal and to split a combined incoming optical signal into the incoming optical signals; and
using at least one feedback loop to adjust an aim or path of at least one of the outgoing optical signals or at least one of the incoming optical signals.
