摘要
为使全数字闭环光纤陀螺在全温度(-40～+65℃)范围内的性能保持一致,采用了控制光源以稳定光功率和波长,以及对集成光器件进行温度补偿两种技术措施。试验结果表明,研制的光纤陀螺在全温度范围内,标度因数和零偏的温度灵敏度分别小于2×10-5℃-1、0.008(°)/(h·℃),达到了中等精度光纤陀螺的要求。
The two technologies are applied to stabilize the performance of closed-loop digital laser fiber optic gyro (FOG) under the temperature from -40 to 65 ℃, one is the laser light control to keep optical power and wavelength unchanged, the other is the compensation for the integrated optic chip. The experiment result is showed that the temperature sensitivities of scale factor and zero drift in the fiber optic gyro designed are 2×10^(-5) 1/℃ and 0.00 8 (°)/(h·℃) respectively in all temperature range, which has met the requirements of middle accuracy gyro.
