激光干涉仪，以激光波长为已知长度，利用迈克耳逊干涉系统测量位移的通用长度测量。激光干涉仪可配合各种折射镜、反射镜等来作线性位置、速度、角度、真平度、真直度、平行度和垂直度等测量工作，并可作为精密工具机或测量仪器的校正工作。<br /> <br /> <font color="DimGray">激光干涉仪</font>有单频的和双频的两种。单频激光干涉仪，从激光器发出的光束，经扩束准直后由分光镜分为两路，并分别从固定反射镜和可动反射镜反射回来会合在分光镜上而产生干涉条纹。使用单频激光干涉仪时，要求周围大气处于稳定状态，各种空气湍流都会引起直流电平变化而影响测量结果。<br /> <br /> <font color="DimGray">激光干涉仪</font>在氦氖激光器上，加上一个约0.03特斯拉的轴向磁场。由于塞曼分裂效应和频率牵引效应, 激光器产生1和2两个不同频率的左旋和右旋圆偏振光。经1/4波片后成为两个互相垂直的线偏振光,再经分光镜分为两路。一路经偏振片1后成为含有频率为f1-f2的参考光束。另一路经偏振分光镜后又分为两路：一路成为仅含有f1的光束,另一路成为仅含有f2的光束。</div> <div
