Abstract
An interferonmetric temperature measurement system is described for determining the temperature of a sample. The system comprises three detectors for measuring various intensities of a beam of electromagnetic radiation reflected off the sample and circuitry for determining the temperature from the intensities. The detectors measure the intensity of the beam and two orthogonally polarized components of the beam.
