How does a laser interferometer work
WebAug 18, 2024 · A laser interferometer measures the resulting distance by splitting a laser beam into two, sending each of the two beams along different directions in space (each along one of the two arms of the detector), and then recombining the beams. If the beams travelled exactly the same distance, then a detector detecting the recombined beam will … WebLaser interferometry is a well-established method for measuring distances with great accuracy. Basic principles Typically a single incoming beam of coherent light source will …
