Changes in the optical path length, caused by displacement or refractive index variations, alter the interference fringes, enabling high-precision measurements of picometer position changes. Advantages of Michelson Interferometers Michelson interferometers offer exceptional precision and reliability by splitting and recombining light to measure smallest displacements, vibrations, and refractive changes with nanometer or sub-nanometer accuracy. Their versatility, non-contact operation, and ability to perform in demanding environments like UHV or cryo-temperature make them indispensable for applications in metrology, optics, and advanced research.
