  • Patent number: 9551618
    Abstract: An accurate and robust wavefront-division polarimetric analysis method and device, allows the quasi-instantaneous measurement of the polarization states of a luminous object. The device can be used to produce a plurality of light beams, all polarized according to different polarization states, from a single upstream light beam. The polarized light beams, which do not overlap and which carry information items that are complementary in terms of polarization, are analyzed simultaneously by a plurality of detectors that measure the luminous intensity of each beam. Processing elements digitally process the luminous intensity values obtained in order to determine the polarization state of the upstream light beam. The operations performed by the processing elements prevent luminous intensity variations in the split light beams during the division of the wavefront of the upstream light beam.
