Claim 3:
4. The method of claim 3, further comprising:
splitting the beam of cross-polarized light into a local oscillator path and a target path using a first beam splitter;
splitting local oscillator path light into a first output and a second output using a second beam splitter;
transmitting target path light to a target and directing the light reflected from the target to the first polarizing beam splitter using an optical path discriminator;
mixing the first output of the second beam splitter and the first output of the first polarizing beam splitter using a first light mixer;
mixing the second output of the second beam splitter and the second output of the first polarizing beam splitter using a second light mixer;
receiving first combined light from the first light mixer at the first detector; and
receiving second combined light from the second mixer at the second detector.
