Abstract
Optical fibre interferometric sensors are described in which the path imbalance of the interferometer is measured by using a frequency modulated source. The technique is analogous to frequency modulated continuous wave (FMCW) radar. Optical FM techniques are described and initial results from a closed loop system presented. The interferometers are totally passive and their state can be read with high accuracy, depending on the total frequency excursion and output signal to noise ratio.
