<p>A fiber optic sensor (10) comprises a flexural disk (12) with fiber optic coils (18, 20) mounted on opposite sides (14, 16) thereof and connected together to form an interferometer (124) that produces an output signal in response to acceleration of the flexural disk (12). The flexural disk (12) is mounted in a housing (24) having first and second end plates (30, 38) with a sidewall (40) extending between them. The sidewall (40) is formed to have an inwardly facing groove (98) in which an outer edge portion (68) of the flexural disk (12) is mounted. A support member (72) extends between the first and second end plates (30, 38) and through a central passage (74) in the flexural disk (12). A damping member (78) is mounted on the central support member (72) and arranged to dampen vibrations of the flexural disk (12) and control the sensor output signal amplitude over a selected freqeuncy band in order to maximize dynamic range.</p> |
