PROBLEM TO BE SOLVED: To provide a suitable compensated accelerometer that uses optical angle sensing. SOLUTION: The compensated accelerometer comprises a housing; a pendulum within the housing, flexibly coupled to a base, wherein the pendulum includes a coil mounted on a movable plate and a curtain having an opening; a light source and a differential light detector generating a signal proportional to the angular displacement of the pendulum; a magnet magnetized in the direction of the axis of the pendulum; a magnetic conductor that, together with the coil and the magnet, is used to return the pendulum to the neutral position; and a feedback circuit generating an output proportional to acceleration experienced by the compensated accelerometer, based on the angular displacement of the pendulum.
