Latest Patents

Among his latest patents is a method for reducing speckles in liquid-crystal displays with coherent illumination. This innovative method involves using laser light to illuminate a liquid-crystal display, where the image is formed by passing light through holographic elements arranged in a matrix pattern. The process includes changing the direction of the beams emitted from these elements through polarization-changing liquid crystal elements, ultimately converting the image-carrying beams into a visible image via a polarization analyzer.

Another notable patent is the speckle-reduced laser illumination device, which is applicable in various fields such as optical microscopy and machine vision systems. This device features a network of planar ridge waveguides with holograms organized to form specific light spots or fields. The design ensures that the holograms are spaced apart at distances equal to or greater than the coherence length, effectively reducing speckling and allowing for precise control of light spot positioning.
