<P>PROBLEM TO BE SOLVED: To provide a system and method for reducing errors in a resonator fiber optic gyroscope. <P>SOLUTION: An exemplary resonator fiber optic gyroscope comprises: a resonator having an optical fiber loop; a light source configured to generate a light beam; and an intensity modulation circuit coupled between the light source and the resonator. The intensity modulation circuit is configured to modulate the intensity of the light beam from the light source to output an intensity modulated signal to the resonator. The intensity modulation circuit is configured to produce the intensity modulated signal such that harmonics of the intensity modulated signal which overlap a primary wave of a counter-propagating light beam in the resonator have an amplitude below a predetermined threshold. Amplitudes below the predetermined threshold are negligible. <P>COPYRIGHT: (C)2013,JPO&INPIT |
