光纤陀螺仪虽然在实验室试验中已经达到了每小时0.01°的转速灵敏度,但它还必须获得在飞机导航系统中应用所需的技术性能。据在华盛顿的海军研究实验室领导人Willan Burms预告,仍然有些问题需要解决。据他说,光纤陀螺中有关元件性能的改善虽能提高光纤陀螺仪的性能,但它的最难办的限制因素在于动态范围。他区分了环型激光器陀螺仪和光纤陀螺的工作,前者的输出是对被测的旋转实施线性再现。他解释说:“在一般的光纤陀螺结构中,输出正比于这种正弦旋转,除非陀螺恰好工作在零交叉点,这意味着输出是非线性的”。Burms说,目前几种型号的光纤陀螺利用反馈来闭合光纤环路,并保持输出为零和信号接近线性。
Fiber-optic gyroscopes, which have achieved rotational speed sensitivity of 0.01 ° per hour in laboratory tests, must also obtain the technical performance required for their application in aircraft navigation systems. According to Willan Burms, leader of the Naval Research Laboratory in Washington, there are still some problems to be solved. According to him, while improvements in component performance in fiber optic gyroscopes can improve the performance of fiber optic gyroscopes, the most difficult constraint is the dynamic range. He distinguished the work of ring laser gyroscopes and fiber optic gyros, where the output of the former was a linear representation of the rotation under test. He explains: “In a typical FOG, the output is proportional to this sinusoidal rotation unless the gyro happens to work at the zero-crossing point, which means the output is non-linear.” Burms said several fiber optic gyros currently use feedback to close the fiber loop and keep the output at zero and the signal nearly linear.
