Abstract:
1. A dynamically reconfigurable hologram comprising: a phase-control layer having a plurality of phase-modulation elements, wherein each phase-modulation element is configured to have a selectable effective refractive index and selectively transmit wavelengths associated with one of three primary color wavelength bands of the visible spectrum, wherein the selectable effective refractive index comprises a negative effective refractive index; and an intensity-control layer having a plurality of intensity-control elements, wherein each of the plurality of intensity-control elements is configured to have a selectable transparency to control an intensity of light transmitted through a respective intensity-control element of the plurality of intensity-control elements, wherein one or more color three-dimensional holographic images are produced by electronically addressing the phase-modulation elements and intensity-control elements to produce wavefronts and control the intensity of light transmitted through the hologram; wherein the phase-control layer further comprises:
