How does a laser interferometer work

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). WebApr 3, 2024 · In that work, laser interferometry was suggested as a solution to overcome the bandwidth and sensitivity limitations of consolidated techniques such as dynamic pressure transducers and condenser microphones. The FLDI presents similar capabilities with further advantages such as adjustable sensitivity and simplicity, and may, therefore, be of ...
