Latest Patents
One of Richard L. Sutherland’s latest patents focuses on switchable volume hologram materials and devices. This innovative approach utilizes a new photopolymerizable material that enables single-step, rapid recording of volume holograms, which possess properties that can be electrically controlled. The polymer-dispersed liquid crystals (PDLCs) outlined in this patent consist of a homogeneous mixture of nematic liquid crystal and a multifunctional pentaacrylate monomer. It also includes a photoinitiator, coinitiator, and a cross-linking agent, with the optional addition of surfactants such as octanoic acid.
The PDLC material is subjected to coherent light exposure to create an interference pattern, leading to the photopolymerization of the new material. This process produces a hologram composed of distinctly segregated liquid crystal domains and cured polymer domains. Notably, the volume transmission gratings made from this novel PDLC material can be electrically switched between nearly 100% diffraction efficiency and nearly 0% diffraction efficiency. By increasing the frequency of the switching voltage, it becomes possible to achieve switching voltages in the range of 50 Vrms.
