Polarization optical reflectometry: the technique for puncture diagnosis

We propose to realize an endoscopic all-fiber clinical device for polarized reflectance spectroscopy based on polarization-maintaining (PM) fiber. Results of testing the above device in model media and the first data of clinical investigations are presented. Investigations in vivo were carried out on the uterine cervix with benign and malignant alterations. 7 female patients were examined. POR technique confirm a possibility of differentiating neoplastic changes by the depolarization ratio.
