Description:

Polarization interferometers are interferometers that utilize birefringent crystals in order to generate an optical path delay between two polarizations of light. In this talk I will describe how I have employed polarization interferometry to make two kinds of Fourier imaging spectrometers; in one case, by temporally scanning the optical path delay with a liquid crystal cell, and in the other, utilizing relative motion between scene and detector to spatially scan the optical path delay through a position-dependent wave plate.
