Latest Patents

Schwartz's latest patents showcase his innovative spirit and commitment to advancing technology.

1. **Double-Doped BaTiO.sub.3 Crystal for Holographic Storage**: This invention introduces a novel photorefractive material comprising BaTiO.sub.3 double-doped with two dopant species, each possessing at least two valence states. One dopant species, cerium, is strategically positioned near the middle of the barium titanate bandgap, while the other, rhodium, is closer to the valence band edge. This unique design enables enhanced sensitivity to both visible and infrared light. The double-doped BaTiO.sub.3 crystal not only boasts impressive photorefractive properties but also offers a dark storage time of several years at room temperature, allowing for nondestructive read-out at an infrared wavelength. Information can be recorded by sensitizing the crystal with a uniform beam of radiation before storing data with a longer wavelength, ensuring an efficient and innovative approach to holographic storage.

2. **Light Valve System and Method with Pulsed Readout**: This patent details a pulsed readout technique designed for liquid crystal light valves, addressing the challenge of readout beam leakage through the light valve mirror. The readout beam is activated only when the semiconductor layer of the light valve is in a non-depletion state, thus improving the reliability of the device. This invention is versatile, applicable to various kinds of modulating inputs, and can utilize either dielectric or metal matrix mirrors.
