Polarimetric optical detector |
摘要 |
This optical polarimetric detector comprises: a first active detector element having a photoconductor (1) with which a first diffraction grating (3) is associated allowing incident light from a first specific polarization direction to be coupled in the first detector element and allowing the latter to detect the light having this first polarization direction; a second active detector element having a photoconductor (1') with which a second diffraction grating (3') is associated allowing incident light from a second polarization direction to be coupled in the second detector element and allowing the latter to detect the light having this second polarization direction. Furthermore, a detector (2) is provided making it possible to eliminate the background noise detected by previous detectors.
