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 … WebOct 5, 2024 · The basic principle is called interferometry, and it can be used to measure all kinds of different things with incredible precision. How does it work? You take a laser beam and split it in half using a semi-silvered mirror (a mirror partly coated with silver so it allows half the light to pass through and reflects the rest away).
