Abstract

Fiber Optic Gyro (FOG) is the most typical application example of fiber optic rate sensor. Theoretically, as the potential inertial sensor of next generation, FOG shows considerable advantages over mechanical gyro in many aspects, such as all-solid-state configuration, no-spinning part and etc. Its promising features bring the following performance: vibration-proof and interference-proof and high reliability. As to the practical application, shock and vibration should be considered when the potential drift sources are concerned. The stress change of fiber coil, the vibration of the optical device pigtail and structural resonance would increase dynamic error. Recently, the engineers on development of FOG and its strapdown system focus on how to eliminate or decrease the vibration error of FOG and make good advantage of this kind of gyro.
