摘要： A method for generating data related at least to the polarization state and the polarization rate, and advantageously to the wavefront shapes, of an incident light beam (51) of any polarization state and any polarization rate, from a single intensity image acquisition Isensor of said light beam (51), using a polarization and wavefront shape imaging system (1) which comprises a polarization modulating mask (2) being a diffractive optical element, and an intensity sensor camera (3), the method comprising :
(A) having previously recorded one set of at least four reference intensity patterns (N1),
(B) recording the single intensity image Isensor of said incident light beam (51),
(C) processing the single intensity image Isensor based on the reference intensity patterns to generate the data related to the polarization state and the polarization rate, and advantageously to the wavefront shapes of the incident light beam (51).
