Abstract: A polarization interference correlation spectrometer comprising a first polarizer for polarizing a sample beam, a Soleil compensator for producing an appropriate optical path difference between the paths of the two orthogonal polarization components of the sample beam polarized by said first polarizer, a second polarizer for synthesizing the two orthogonal polarization components accompanied with said optical path difference and generating interference, and a photoelectric transducer for deriving said interference as a modulated electric signal.
