Abstract
A resiliently mounted ring laser gyro is dithered below its resonant frequency with a waveform differing from the sine waveform. This is achieved by a piezoelectric motor formed by several piezoelectric elements in a pile. The motor is acting tangentially on a support for the laser and the support takes the form of a strong biased torsion spring.
