ABSTRACT:
Fiber optic gyroscopes having integrated power measurement capabilities and related methods and apparatus. More particularly, fiber optic gyroscopes having an integrated method for determining the optical power by applying an electronic stimulated rate internal to the closed loop digital electronics of the gyroscopes and monitoring the counts out per second (COPS) using each gyroscope's counts output signal. Knowing a COPS value, the optical power can be determined by dividing a constant K by the COPS value, i.e. Optical Power=K/COPS. The value of K is specific to each gyroscope, and can be calculated or measured.
