| 摘 要： | 理论上,采用四极对称法绕制的光纤线圈能很好抑制温度梯度对光纤陀螺的影响,实际上,由于结构加工不理想或石英缠绕引起自身的机械形变,使线圈内外的温度变化,从而导致陀螺输出速率误差.该文分析并给出了光纤陀螺输出速率误差与线圈内外温度差或温度梯度间的关系,提出了一种补偿光纤陀螺因温度变化而导致输出速率漂移误差的方法,尽管光纤陀... |

| Abstract: | Theoretically,the effect of the temperature gradient on the fiber optic gyroscope(FOG) can be well suppressed by using the quadrupole winding.In fact,the imperfect structure or winding causing glass coil distortion leads to FOG output rate error when there are temperature changes between FOG housing and the sensor coil spool.This paper shows a relationship between FOG output rate error and temperature change or temperature gradients.A method of compensating the FOG output drift rate error caused by the temp... |
| Keywords: | FOG quadrupole winding temperature gradients correction factor |
