ABSTRACT OF THE DISCLOSURE A photopolarimeter for the simultaneous measurement of all four Stokes parameters of light. The light beam, the state of polarization of which is to be determined, strikes, at oblique angles of incidence, three photodetector surfaces in succession, each of which is partially specularly reflecting and each of which generates an electrical signal proportional to the fraction of the radiation it absorbs. A fourth photodetector is totally light absorbing and detects the remainder of the light. The four outputs thus developed form a 4x1 signal vector ? which is linearly related, ? = ??, to the input Stokes vector ?. Consequently, ? is obtained by ? = ? -1 ?. The 4x4 instrument matrix ? must be nonsingular, which requires that the planes of incidence of each of the light beams are all different. For a given arrangement of four detectors, ? can be either computed or determined by calibration.
