Abstract
Differential interference contrast (DIC) microscopy is shown to
be equivalent to an incomplete Stokes polarimeter capable of probing
optical properties of materials on microscopic-length scales. The
Mueller matrix for a DIC microscope is calculated for various types of
samples, and the polarimetric properties for DIC component parts of a
spaceflight microscope are spectrally measured. As a practical
application, a measurement of the index mismatch between colloidal
particles and a nearly index-matched fluid bath was
performed.
