| 摘要 |
A hyperspectral holographic polymer dispersed liquid crystal (HPDLC) medium comprising broadband reflective properties comprises dopants that result in a hyperspectral HPDLC with fast transitional switching speeds. A technique for fabrication of hyperspectral broadband HPDLC mediums involves dynamic variation of the holography setup during HPDLC formation, enabling the broadening of the HPDLC medium's wavelength response. Dopants may include carbon nanoparticles, piezoelectric nanoparticles, multiwalled carbon nanotubes, a high dielectric anisotropy compound, semiconductor nanoparticles, electrically conductive nanoparticles, metallic nanoparticles, or the like. The hyperspectral HPDLC having fast switching speeds may be used to form a mirror stack with electrically-switchable beam steering capability. |
