Paper Abstract

A technique using an electro-optic phase modulator has been developed to add a ±90 degree phase shift to the Sagnac interferometer gyro. The introduction of the phase shift produces maximum sensitivity at low angular rates. The modulated output of the gyro is detected and processed by a single channel ac coupled sample and hold amplifier. The amplifier output is normalized to compensate for laser output and preamplifier gain drift.
