light beam deflection

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 light beam 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.

高斯光束的自偏转程度随着入射光强的变化关系与外加电场的情况相似。
