Abstract

A new type of the in-line optical fiber ellipsometer based on the Sagnac interferometer is described. The possibility of the detection of the changes of full polarization state in this system containing standard single-mode fiber by an appropriate applied modulation technique is discussed. The device uses interferometric measurement technique based on the fourth Fresnel-Arago's condition, which secures very good system accuracy and stability. The results of investigations of the system are presented.
