DEVICE AND METHOD FOR DETERMINING A PIECE OF POLARISATION INFORMATION AND POLARIMETRIC IMAGING DEVICE

摘要

The invention relates to a method and to a device for determining a piece of polarisation information on a measurement point of a target sample, the device comprising: -a light source capable of emitting a rectilinearly polarised light beam in a predefined direction, the light beam being intended to be reflected by the measurement point of the target sample; -a unit for computing the piece of polarisation information on the measurement point using the beam reflected by the target sample; -a waveguide for guiding the incident beam towards the target sample and the reflected beam towards the computing means; and -a unit for rotating the polarisation, capable of rotating two orthogonal polarimetric components of the incident beam exiting the waveguide and two orthogonal polarimetric components of the reflected beam before passing through the waveguide.
