Abstract
A differential heterodyne Mach-Zehnder interferometer using a digital phase tracking scheme is described. The tracking device is a prototype for the new fibre optic hydrophone and is capable of maintaining the interferometer at a maximum sensitivity in the presence of large random drifts up to 200 pi rad s-1.Keywords
