Passive ring resonator angular rate sensor.

摘要

A passive ring resonator angular rate sensor includes a pair of beams (40, 41) injected into a passive resonator (10). Biasing means (33, 35, 38) serve to modulate the frequency difference between said first and second beams and further means (37) serve to randomize said modulation of said frequency difference in order to reduce the light scattering effects in said sensor.
