Singleshot Spectroscopic Polarimetry Using Channeled Spectrum

摘要

This paper describes the channeled spectropolarimetry capable of the singleshot measurement of the state of polarization (SOP) of polychromatic light. A pair of fairly-thick birefringent retarders are incorporated into the polarimeter so that all the spectrally-resolved Stokes parameters can be determined at once from only a single channeled spectrum. The principle of this method as well as its application for the ellipsometric study of thin films are presented.
