A method for roll angular error measurement of NC machine tool vertical axis was studied based on straightness measurement using laser interferometers system.

以激光干涉仪直线度误差测量为基础研究了数控机床垂直轴滚转角误差的检测方法。

This fact leads to use compensation techniques to correct and minimise those errors that can be measured by advance measuring instruments such as laser interferometers.

这一事实导致使用补偿技术，以纠正和减少那些可以提前测量仪器，如激光干涉仪测量误差。

Laser interferometers are looking for disturbances in their experimental set-ups that are equivalent to mere fractions of the diameter of a proton, one of the particles that make up the nucleus of an atom.
