Abstract
Systems and methods for dynamic PLC modulation are provided. In certain embodiments, a gyroscope system includes a block having cavities and passages that define a path; mirrors, each located in one of the cavities, direct light along the path defined by the cavities and the passages; a mirror drive coupled to one of the mirrors to change a position of the mirror, wherein the path's length is changed as the mirror's position changes; a photodetector that measures power of light along the path; and a controller that provides a control signal indicative of an amplitude of PLC modulation and a PLC frequency to the mirror drive; wherein the mirror drive, in response to the control signal, changes the position of the mirror at the frequency, wherein the mirror drive moves based on the amplitude; and wherein the controller changes the amplitude in relation to the measured power of the light.
