Abstract
A system for accurately controlling the motion of a mirror membrane used in a three-dimensional display system. The system senses the pressure differential across the membrane mirror as a means of indirectly measuring mirror position. This pressure differential is converted into an electrical signal which is used in a closed loop feedback system to force the membrane position to follow accurately the command signal.
