Abstract

A design uses micro-cantilever beam with matching twin long period optic fiber grating which are sensitive to the strain and the vibration as the sensor head. And the difference amplifies the micro-displacement of wavelength which caused by strain or vibration. Special cladding material is used to eliminate the interference which temperature brings. The design has the good capability to detect the micro-information and smooth the bias lighting.
