Abstract
An acceleration transducer for use in an accelerometer includes a proof mass that comprises a transmissive optics device arranged to receive an optical signal such that the optical signal propagates through the transmissive optics device along a first optical path having a selected optical path length. A support assembly is arranged to support the proof mass such that the transmissive optics device moves from a reference position along a selected sensing axis in response to an acceleration of the proof mass along the selected sensing axis and produces an optical path length change that indicates the acceleration.
