Abstract (en)

[origin: WO2008046820A1] The subject of the invention is a polarimetric imaging system having an optical axis and comprising means (35) for detecting and analysing the light backscattered by an object illuminated by a light source and at least one programmable waveplate (33), characterized in that the programmable waveplate comprises a material with an isotropic electrooptic tensor and a set of at least three electrodes placed along directions parallel to the optical axis of the imaging system.
