The optical fiber accelerometer owns exceptional advantages in various industrial applications due to its high sensitivity, immunity to electromagnetic interference, small size, low cost and easy to form sensor network etc. This study aims to evaluate an optimized interferometric optical fiber accelerometer based on Michelson structure. An integral parameter S was firstly proposed to assess the general performance of the accelerometer including both the sensitivity and resonance frequency, the compliant cylinder of the accelerometer proposed in this study was optimized as the composite structure materials, two typical sensitivity enhanced elastic materials of polycarbonate and silicone rubber were selected. This new type accelerometer was capable to provide higher phase sensitivity and wider flat bandwidth with optimized proportional mixing between two materials. The comparison analysis of Young’s modulus and Poisson ratio on the promotion of integral parameter S was finally discussed.
