Abstract
A system for offsetting lock-in in a spring-suspended ring laser gyroscope by dithering it by means of a torquer whose input is controlled by the sum of an analog positive-feedback signal for cancelling out losses due to damping and a piecewise-constant signal for adjusting the effective dither angular velocity phase in each cycle.
