Latest Patents
Pouria Valley holds a patent for a "Variable focal length achromatic lens system comprising a diffractive lens and a refractive lens." This innovative lens system includes a flat liquid crystal diffractive lens and a pressure-controlled fluidic refractive lens. The diffractive lens is designed with a flat binary Fresnel zone structure and a thin liquid crystal layer, which allows for high efficiency and rapid switching times while using a low AC voltage input. The focusing power of the diffractive lens can be adjusted by electrically modifying the sub-zones and re-establishing phase wrapping points. The refractive lens features a fluid chamber with a flat glass surface and an opposing elastic polydimethylsiloxane (PDMS) membrane surface. By inserting fluid volume through a pump system into the clear aperture region, the curvature of the membrane is altered, which adjusts the focal position of the refractive lens. This innovative coupling of fluidic and diffractive lenses significantly reduces primary chromatic aberration at selected focal lengths. Potential applications for this technology include miniature color imaging systems, medical and ophthalmic devices, and any design that utilizes variable focal length achromats.
