Lloyd mirror

用法例句

In order to measure departure from straightness, a new method is designed to change the slit separation and the distance of interference fringes by making the turning of Lloyd's mirror caused by departure from straightness in the improved Lloyd's mirror apparatus.

利用改进的洛埃镜干涉装置,设计了由直线度误差使洛埃镜偏转,通过改变等效双狭缝间距,进而改变干涉条纹间距的新的直线度误差测量方法 由导出的直线度误差与干涉条纹间距之间的关系,并用最小包容区域法对直线度误差进行评定 测量结果表明,新的直线度误差测量方法是可行的 此方法特别适用于短距离连续空间直线度误差的测量,并且测量系统具有结构简单、操作方便、精度高、应用范围广等优
