WebSep 12, 2024 · The Michelson interferometer (invented by the American physicist Albert A. Michelson, 1852–1931) is a precision instrument that produces interference fringes by … WebMany interferometers have broadband frequency responses that extend up to several hundred megahertz. Some systems offer in-plane ultrasonic measurement, whilst most offer out-of-plane measurements. Emphasis is placed on their potential for industrial applications, taking into account the likely sample-surface roughness and environmental ... WebNTT RESEARCH. May 2024 - Present1 year.
