摘要
A spectroscopic polarimetric system of broad spectral range, includes a light source suitable for emitting an incident light beam over a wavelength range, a polarization state generator (PSG), a polarization state analyzer (PSA), and a detector. The PSG and the PSA have respective elements for modulating the polarization of the light beam. The elements of the PSG for modulating polarization are suitable for generating a sequence of m polarization states with m4 at each measurement wavelength, the elements of the PSA for modulating polarization are suitable for determining a sequence of n polarization states with n4 for each measurement wavelength, and the detector elements are suitable for acquiring a sequence of N measurements with 16N≦n×m at each wavelength to extract therefrom a polarimetric spectroscopic measurement of the Mueller matrix of the sample. An extended spectroscopic polarimetric measurement method is also described.
