Abstract
A system for polarimetric characterization of a target that includes a liquid light guide (LLG) for propagating light from a light source to the target (S) at least one of a Polarization State Analyzer (PSA) serving to analyze polarization of light having propagated into the LLG and that has been reflected by the target, and a Polarized State Generator (PSG) for modulating the polarization of light injected into the LLG, an optical detector for detecting light backscattered by the target (S) that has been illuminated by the LLG.
Claims21
A system for polarimetric characterization of a target, comprising:
- a liquid light guide (LLG) for propagating light from a light source to the target,
- at least one of:
- a Polarization State Analyzer (PSA) serving to analyze the polarization of the light having propagated into the LLG and that has been reflected/backscattered by the target, and
- a Polarized State Generator (PSG) for modulating the polarization of light injected into the LLG,
- a camera for detecting light reflected/backscattered by the target that has been illuminated by the LLG, and
- a detection channel separate from the LLG used for the illumination, and in which light propagates before reaching the camera.
