Abstract
An accelerometer based on an optical displacement sensor is disclosed. An embodiment of the present invention directs a light beam toward an optically resonant cavity and detects both the reflected and transmitted optical beams that result from interaction with the optically resonant cavity. The optically resonant cavity has a cavity length that is based on the position of a proof mass that moves in response to an acceleration.
