Latest Patents
One of his latest patents involves switchable volume hologram materials and devices. This innovative photopolymerizable material allows for single-step, fast recording of volume holograms with properties that can be electrically controlled. The polymer-dispersed liquid crystals (PDLCs) used in this invention consist of a homogeneous mixture of a nematic liquid crystal and a multifunctional pentaacrylate monomer, along with a photoinitiator, coinitiator, and cross-linking agent. Optionally, a surfactant such as octanoic acid may also be included. The PDLC material is exposed to coherent light to create an interference pattern within the material. The photopolymerization process results in a hologram featuring clearly separated liquid crystal domains and cured polymer domains. Volume transmission gratings made with this new PDLC material can be electrically switched between nearly 100% diffraction efficiency and nearly 0% diffraction efficiency. By increasing the frequency of the switching voltage, switching voltages in the range of 50 Vrms can be achieved.
