Abstract

One of the more successful multimode fiber optic sensors to data has been the Faraday sensor. This type of device has been used to detect rotational speed, torque, proximity and other parameters. When in a reflective configuration, the transducer element has consisted of a thin Faraday film between a polarizer and a mirror. In this paper, it is shown that enhanced performance of the sensor results when the polarizing element is removed from the transducer. A theoretical analysis is presented along with supporting experimental results.
