Abstract
An imaging interferometric transform spectropolarimeter configured to simultaneously collect four polarizations. In one example, an spectropolarimeter includes a dual-beam interferometric transform spectrometer configured to receive electromagnetic radiation from a viewed scene, and including first and second focal plane arrays that are spatially registered with one another, a first polarizer coupled to the first focal plane array and configured to transmit only a first pair of polarizations to the first focal plane array, and a second polarizer coupled to the second focal plane array and configured to transmit only a second pair of polarizations to the second focal plane array, the second pair of polarizations being different than the first pair of polarizations.
