Full-Complex Wavefront Generation for 3-D Volumetric Holographic Displays

High-speed computer and high resolution display technology have advanced to the point that two dimensional (2-D) display technologies present more information than can be efficiently used. Advanced computer and display technologies have been combined with advances in spatial light modulation (SLM) technology to provide the user 3-D image cues. SY Technology proposes an innovative technique to demonstrate 3-D etric wavefronts using 2-D SLMs. SY technology will accomplish this by combining two specialized high-speed 2-D pixelated devices (LCD), each separately modulating amplitude or phase, into an architecture generating the full-complex amplitude of an optical wavefront. Users can then combine an object's shape and complex reflectivity to determine the optical complex wavefront reflected from an object. In related DARPA supported work, SY Tech. is constructing a phase-only diffractive projection television using rapid computation algorithms to convert video data into equivalent diffraction patterns. These patterns are then displayed on and demonstrate generation of calculated full-complex amplitude wavefronts. We will also analyze methods of extending the SLM technology to support future commercialization of this innovative approach.
