Abstract

A phase swept pseudo-heterodyne detection scheme suitable for use with all-fibre versions of the fibre gyroscope is described. The output carrier signal, which is phase modulated by the Sagnac shift, is generated by employing sinusoidal phase modulation via a piezoelectric fibre stretcher in combination with selective detector gating.
