The Angle of rotation, which provides a measure of the current flowing in the coil, is measured by the movement of the needle or by the deflection of a Beam of light reflected from the mirror.
旋转角度可用来度量线圈内通过的电流,角度用指针的转动或镜面反射光线的偏转来测定。

The method is based on measuring the deflection of rays from a collimated lightbeam due to gradients in refractive index.
平行光通过折射率存在梯度的场,光线产生偏转,即产生云纹效应。

The relation of the degree of self-deflection of matching Gauss beam and the intensity of incidence light is similar to external electric field.
