We present the design process of a fiber Bragg grating based fiber-optic single-axis acceleration sensor with minimized crosstalk. Crosscoupling of non-directional accelerations is minimized by introducing a unique double-membrane fixture of the sensor's mass of inertia leading to an almost diagonal form of the sensors stiffness-matrix. The sensor's resonance frequency, the sensor's sensitivity towards the stiffness of the spring-mass system and the mass of inertia are calculated from an analytical model and are verified by FEM simulation of the sensor. A singleaxis sensor design yielding a resonance frequency of 6.0 kHz with a sensitivity of Δλ = 1 pm/g at a non resonant acceleration is proposed.
