광섬유자이로의 고리 온도변화에 의한 바이어스 특성 및 온도 보상 = The Bias Drift Due to Fiber Coil Temperature Variation and the Temperature Compensation in Fiber Optic Gyroscope

다국어 초록 (Multilingual Abstract)

The bias characteristics due to the changes of temperature and temperature gradient of fiber coil are investigated in fiber-optic gyroscope. The bias performance is degraded with the changes of temperature and temperature gradient of fiber coil. The temperature compensation using both the temperature-dependent bias measurement and the temperature-induced error model of fiber-optic gyroscope improves the bias stability about 3 times as much as the uncompensated original case, which leads to very stable bias performance over the temperature range from $-35^{\circ}C$ to $+77^{\circ}C$.
