Abstract: The invention relates to an electronic polarimetric imaging system use in a colposcopy device for in vivo monitoring a cervix, which is provided with a light source for illuminating the observable cervix and at least visual means for monitoring said cervix, wherein the illumination optical path directed to the cervix and the image optical path coming back from the cervix are separated from each other on at least a portion of the paths thereof. The inventive system comprises a polarimetric adapter housing which is removable in the separated portion of the illumination and image optical paths and comprises a polarization state generator (PSG) positioned on the illumination optical path and a polarization analyser (PSA) positioned on the image optical path, wherein said polarization state generator (PSG) and polarization analyser (PSA) are designed in such a way that they are controllable. Said invention makes it possible to obtain several polarimetric characterisation levels.
