optic elasticity axes

On the basis of those metioned above, the expression of quadrature error and the ratio between quadrature error and sense signal were induced respectively when the principal axes of elasticity of outer-frame and inner-frame rotated a little angle separately.

在此基础上,利用弹性主轴原理,分别推导了内外框弹性主轴偏转产生的正交误差信号表达式及正交误差信号和敏感信号的比值表达式。
