Abstract

This paper presents the results of a series of experiments performed on a fibre optic gyroscope to determine the effect of different phase modulation frequencies and modulation depths on coherent backscatter noise. The results suggest that coherent backscatter is modulated in quadrature with the Sagnac signal although a presently unexplained noise source is also detected in-phase with the Sagnac signal.
