Abstract

Noise in a n open-loop, high sensitivity fiber optic gyro, including shot, thermal, electronic, and source (RIN) contributions, is investigated experimentally. The gyro is an al-fiber, dynamically biased, open-loop gyro operating at 1.06 micrometers . Fiber lengths of 1.0 and 2.86 km were used, both wound on 16cm radius forms. A noise subtraction technique was used to reduce RIN noise. Fits to the total noise spectrum implied approximately 40 percent residual RIN remained after subtraction. With this assumption contributions to the random walk coefficient (RWC) are calculated and shown to be in agreement with experiment. A RWC of 0.67 10^-4 deg/(root)hr was obtained.
