Design and Analysis of a Novel Dual FBG Accelerometer Based on Lantern Shape Metallic Shells

A novel dual FBG (DFBG) accelerometer based on lantern shape metallic shells is designed and analyzed. The DFBG accelerometer is based on the push-pull structure, which is used to eliminate common noises and disturbances. The axial size of the DFBG accelerometer is shortened by special combination of the mass and the elastic shells. The size of the optimized DFBG accelerometer is only 24 mm×24 mm×...
