Abstract: We propose a resonant-frequency-adjustable fiber Bragg grating (FBG) accelerometer. The accelerometer employs a special hexagonal energy transfer structure and a microhelical cylinder as a ...

Abstract: We propose and demonstrate a spring-mass structure accelerometer based on a fiber Bragg grating Fabry-Perot interferometer (FBG-FPI). The sensitivity and resonant frequency of the ...
