Abstract

We analyze the crosstalk of compliant cylinder type fiber optical accelerometers using 3D finite element analysis. For a standard design we obtain vibrational modes (transversal and torsional) having their eigenfrequencies below the eigenfrequency of the principal mode, i.e. the longitudinal mode vibrating parallel to the axis of axial symmetry. Through the inclusion of two diaphragms we show that for this new topology the principal mode is the fundamental mode. We have constructed such topology and tested it. A responsivity of 2000 rad/g at an optical wavelength of 1550 nm and a crosstalk of-26 dB was achieved, ignoring one resonance.
