How does a laser interferometer work
WebDec 14, 2024 · Laser feedback-based self-mixing interferometry (SMI) is a promising technique for displacement sensing. However, commercial deployment of such sensors is being held back due to reduced performance in case of variable optical feedback which invariably happens due to optical speckle encountered when sensing the motion of non … http://ilayo.staffpro.net/what-is-laser-interferometer

A laser beam of light is generated and directed toward a beam splitter, which splits it into two separate and equal beams ...
WebMay 15, 2016 · Laser is coherent light, so with a technique called interferometry you can actually measure distance with a resolution of less than a micro-meter, regardless of your timing resolution. It should be noted that the measurement produced by interferometry has half-wavelength periodicity (e.g. 200-350nm for visible light). WebJul 11, 2024 · At one end of the bench is a device called a laser interferometer, which can precisely measure distances along the tape. Laser interferometers work by splitting a laser beam in two. One of the beams, the reference beam, goes directly to a detector, while the other, a measuring beam, goes toward a reflector on the side of the microscope.
