ABSTRACT:
A deformable media spatial light modulator utilizes a transmissive deformable media disposed between a deformable transmissive conductor and a substrate. A plurality of electrodes are affixed to the substrate. A potential control is provided to control the potential difference between each electrode and the conductor. A wavefront to be modulated is incident upon the transmissive conductor, traverses the media and is incident upon a reflector, reverses direction, traverses the media a second time and exits the modulator. By allowing the wavefront to be modulated to traverse the media, several enhancements occur including an increase in sensitivity. The increase in sensitivity exhibits a dependence upon the index of refraction of the media.
