Abstract
An accelerometer having a charged particle electrostatically suspended between opposed field plates in a null position when the sum of the forces on the acelerometer equals zero, the accelerometer comprising LEDs projecting light beams for defining opposed boundaries of the null position between the opposed plates, light detectors for detecting occlusion of the light beams by the particle when the particle moves from the null position into the paths of the light beams, and a particle control system responsive to the light detectors for varying the electrostatic field generated by the opposed plates to return the particle to the null position.
