Claim 8:
9. The apparatus of claim 8, further comprising:
a first beam splitter configured to split the cross-polarized light into a local oscillator path and a target path;
an optical path discriminator configured to transmit target path light to the target and direct the light reflected from the target to the first polarizing beam splitter;
a second beam splitter configured to split local oscillator path light into a first output and a second output;
a first light mixer configured to mix light from the first output of the first polarizing beam splitter and the first output of the second beam splitter; and
a second light mixer configured to mix light from the second output of the first polarizing beam splitter and the second output of the second beam splitter, wherein the first detector is configured to receive first combined light from the first light mixer and the second detector is configured to receive second combined light from the second light mixer.
