Claim 11:
12. The system of claim 11 wherein the first illumination optics comprise:
a first beam splitter that splits the first coherent light into the first beam and the second beam, and that establishes a first optical path for first beam that leads to the sample and a second optical path for the second beam that bypasses the sample and leads to the detector;
a first universal polarizer positioned along the first optical path, wherein the first universal polarizer establishes the first polarization for the first beam;
a second beam splitter downstream of the first universal polarizer along the first optical path;
a mirror positioned along the second optical path; and
a second universal polarizer downstream of the mirror and positioned along the second optical path, wherein the second universal polarizer establishes the second polarization for the second beam.
