  • Publication number: 20140080040
    Abstract: A hyperspectral holographic polymer dispersed liquid crystal (HPDLC) medium comprising broadband reflective properties may comprise dopants that result in a hyperspectral HPDLC with fast transitional switching speeds. Dopants may include alliform carbon particles, carbon nanoparticles, piezoelectric nanoparticles, multiwalled carbon nanotubes, a high dielectric anisotropy compound, semiconductor nanoparticles, electrically conductive nanoparticles, metallic nanoparticles, or the like. A technique for fabrication of hyperspectral broadband HPDLC mediums may involve dynamic variation of the holography setup during HPDLC formation and spatial multiplexing that may enable broadening of the HPDLC medium's wavelength response. Fabrication may include concurrently running multiple exposures and exploiting superpositioning of the resultant gratings. The hyperspectral HPDLC may be capable of blocking and/or filtering wavelengths in the range of approximately 390 nm to approximately 12 ?m.
