Title (EN) ELECTRONIC POLARIMETRIC IMAGING SYSTEM FOR A COLPOSCOPY DEVICE AND AN ADAPTER HOUSING
(FR) SYSTEME D'IMAGERIE POLARIMETRIQUE ELECTRONIQUE POUR APPAREIL DE COLPOSCOPIE
Abstract:
(EN) 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 polarisation state generator (PSG) positioned on the illumination optical path and a polarisation analyser (PSA) positioned on the image optical path, wherein said polarisation state generator (PSG) and polarisation analyser (PSA) are designed in such a way that they are controllable. Said invention makes it possible to obtain several polarimetric characterisation levels. The adapter housing is also disclosed.
(FR) L'invention concerne un système d'imagerie polarimétrique électronique pour appareil de colposcopie destiné à l'observation in vivo d'un col utérin, l'appareil de colposcopie comportant une source de lumière pour éclairage du col à observer et des moyens d'observation au moins visuels d'une image dudit col, le trajet optique de l'éclairage vers le col et le trajet optique de l'image en retour du col étant séparés l'un de l'autre sur au moins une partie de leurs trajets. Selon l'invention, le système comporte un boîtier adaptateur polarimétrique amovible dans la partie séparée des trajets optiques de l'éclairage et de l'image, ledit boîtier adaptateur polarimétrique comportant un générateur d'états de polarisation (PSG) sur le trajet optique de l'éclairage et un analyseur de polarisation (PSA) sur le trajet optique de l'image, le générateur d'états de polarisation (PSG) et l'analyseur de polarisation (PSA) étant commandés. Plusieurs niveaux de caractérisation polarimétrique sont possibles. Un boîtier adaptateur est revendiqué.
