Outline of Final Research Achievements

We proposed and experimentally investigated an optical interferometry using laser light with high-frequency phase modulation in order to achieve single precision measurement of high-speed and minute displacement. A simple experimental setup composed of optical modulators and optical fibers used in optical communications systems was realized. We newly developed a method using high-frequency sinusoidal phase modulation in addition to the initially proposed method that uses triangular phase modulation, and proved that single measurement of the dynamic displacement for 50-MHz vibration is possible.
