概要
FOD (Fiber Optical Doppler) sensor, that can measure elastic wave in wide-band frequency, has been inve nted and developed, which utilizes Laser Doppler effect within an optical fiber. In particular, FOD sen sor can detect acoustic emission (AE), which is sometimes very useful parameter to monitor in-situ dama ge at various equipments. Report herein is its measurement principle and its application for field use.
