Abstract:
1. An imaging polarimeter, comprising: a monolithic beam splitter configured to receive a first light ray and to split the first light ray into second, third, fourth, and fifth light rays such that the second, third, fourth, and fifth light rays are simultaneously received on a flat focal plane; a sensor array disposed on the flat focal plane configured to output first, second, third, and fourth signals indicative of first, second, third and fourth intensities, respectively, of the second, third, fourth, and fifth light rays, respectively; and a computer operably coupled to the sensor array, the computer configured to determine first, second, third, and fourth Stokes parameters for a pixel of the sensor array based on the first, second, third, and fourth signals, respectively, the computer further configured to store the first, second, third and fourth Stokes parameters in a memory device.
