Abstract

A miniaturized FBG accelerometer based on a lantern-shape metallic shell is demonstrated. The shell structures are analyzed and optimized using ANSYS. A Michelson interferometer system is applied to acquire signals. The accelerometer sensitivity is 43.6 pm/g, the resonant frequency is 1000 Hz, and the orthogonal crosstalk is -15.3 dB.
