An analysis system comprises a transmitting device () and a receiving device (). The transmitting devices comprises means for illuminating an object (), or a part of the object, by a first light beam () consisting of signals with two distinct frequencies and first orthogonal polarisation states. The receiving device comprises means () for detecting, in a second light beam with second polarisation states and resulting from the illumination of the object to be analysed by the first light beam, a signal at a beat frequency equal to a difference between the two frequencies of the first light beam; and means () for obtaining information relating to the depolarising or dichroic character of the object, or of the part of the object, according to the detection or not of a signal at the beat frequency.
