MOEMS accelerometer based on double Fabry-Perot interferometers and closed loop

  • A micro-opto-electro-mechanical accelerometer based on differential double Fabry-Perot interferometers(DFPI) and closed loop was designed. The principle and the structure of the accelerometer were introduced. Inertial sensitive module was used to translate carrier’s acceleration measurement to its displacement measurement. The displacement was measured by Fabry-Perot interferometers composedof the mass and the end surface of fiber self-focusing lens. The structure of differential DFPI was designed to improve the sensitivity and restrain the influence of environment factors such as temperature. The closed loop accelerometer using electrostatic servo technology was put forward to improve the output linearity and dynamic range. The mathematic model of the accelerometer was founded, and particular calculation and analysis was made for important parameters, such as sensitivity, carrying capacity of the sensitivity head, natural frequency, etc. The parameters were designed under the requirement of some background. The results show that the system precision can be better than 5×10-6g.
