ABSTRACT:
A reflective deformable conductor (40) is separated from a transmissive electrode (60) to form a capacitance transducer (C2) and separated from a second electrode (18) to form a modulator pixel (66). The pixel (66) and transducer (C2) are series coupled capacitors. Transmissive electrode (60) and deformable conductor (40) are electrically connected to a feedback control loop (68) which sums an input signal and a negative feedback signal related to the deformations of conductor (40) to control the potential difference applied between the second electrode (18) and the conductor (40). Varying the input signal varies the deformation of the conductor (40) thereby phase modulating a wavefront incident on the transmissive electrode (60) traversing the capacitance transducer (C2) to impinge on and be reflected by the conductor (40) and exit the transducer (C2).
