Abstract:

This disclosure describes fiber optic gyroscopes that have integrated power measurement capabilities, and related methods and apparatus. More particularly, it describes determining the optical power of a fiber optic gyroscope (FOG) by temporarily adjusting the phase difference between two counter-propagating light beams, measuring the change in light intensity caused by the phase difference adjustment, and using the measured change in light intensity along with known characteristics of the FOG to compute an optical power value. The temporary adjustment in phase difference is preferably done in such a manner not to disturb the normal operation of the FOG.
