Abstract
An accelerometer includes a membrane; a laser source, the laser source producing a laser beam, the laser beam directed at the membrane causing the membrane to vibrate; a transparent cap, the transparent cap disposed between the laser source and the membrane; an antireflecting film disposed on an outer surface of the transparent cap; and a detector sensing a reflected portion of the laser beam, the reflected portion including a modulated intensity. An acceleration signal is based in part on the frequency of the modulated intensity of the reflected portion of the laser beam.
