【摘要】：全温标度因数变化大小直接影响光纤陀螺的应用效果。随着中高精度光纤陀螺在复杂工况下的广泛应用,对陀螺标度因数变化的要求也在不断提高。光纤长度和光纤环平均直径在全温范围内的变化量是全温标度因数变化最大的影响因素。本文介绍了控制该变化量的常规方式,并提出通过不同排纤方式和不同光纤环窗口比的方法来进一步减小这种变化量的方法。通过仿真和试验证实:某型中等精度光纤环在不同制作工艺条件下全温标度因数变化量有将近300×10~(-6)的差值。
[Abstract]:The change of total temperature scale factor directly affects the application effect of fiber optic gyroscope (fog). With the wide application of fiber-optic gyroscope (fog) with medium and high precision in complex working conditions, the demand for the change of scale factor of fog is also increasing. The variation of fiber length and the average diameter of fiber ring in the whole temperature range is the most important factor affecting the change of the total temperature scaling factor. This paper introduces the conventional ways of controlling this variation, and puts forward a method to further reduce the variation by using different fiber arrangement and different window ratio of fiber loop. The results of simulation and experiments show that the variation of the total temperature scaling factor of a fiber ring with medium accuracy is nearly 300 脳 10 ~ (-6) under different fabrication conditions.
