[交流] 【求助】术语翻译求助（beam shear）已有1人参与

请问beam shear是什么意思？
附原文：
The corner-cube design is inherently insensitive to beam
translation and rotation in the idealized case of plane
wave interferometer beams. The in-line interferometer
extends this property to the entire optical path. The two
interfering beams can, however, be translated relative to
one another: this occurrence is termed beam shear. Beam
shear can be introduced by motion of the interferometer
base or comer cubes, especially translations of the falling
comer cube.
