Claim 0:
1. An apparatus comprising:
a monostatic optical terminal configured to transmit and receive optical signals over multiple optical channels through an aperture, the monostatic optical terminal comprising:
multiple transmit channels configured to provide outgoing optical signals for transmission by the monostatic optical terminal and multiple receive channels configured to receive incoming optical signals obtained by the monostatic optical terminal;
for each optical channel, a polarization rotator and a half waveplate collectively configured 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;
a polarization beam splitter/combiner configured 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
at least one feedback loop configured to adjust an aim or path of at least one of the outgoing optical signals or at least one of the incoming optical signals.
