Paper Abstract

A simple phase tracking circuit for interferometric fiber sensors is described. The scheme is based on the generation of sine and cosine dependent interferometric outputs using phase generated carrier homodyne detection, and cross-multiplication of these outputs with sine/cosine components of an electronically adjustable phase term. The use of the scheme for providing wide dynamic range sensing with an open loop fiber gyroscope is also reported.
