Outline of Final Research Achievements |
Fiber Bragg grating (FBG) is a fiber optic type device that reflects a specific type of light. A Fabry-Perot interferometer consisting of a low reflectance FBG is introduced as the sensor element for vibration measurement, thereby relaxing the restrictions on the sensor installation position. The sensor is read out using a high-speed wavelength sweep obtained by modulating the current of alaser diode, resulting in a high-speed measurement.
