Latest Patents

Among his latest patents is a beam expander and method of operating the same. This invention includes first and second optical elements that are spaced apart, along with a light diffuser that diffuses incident light through an angular aperture. The first optical element in-couples the diffused light, ensuring that light exiting it has a specific cross-sectional shape. Additionally, light with a different cross-sectional shape is incident on the second optical element, which out-couples the light. Another notable patent is a beam expander that features a composite waveguide with multiple waveguide elements and a dichroic coating. This design allows for the input of a collimated incident beam, which is then divided into multiple wavefronts and mixed by total internal reflection. This innovation enhances the coherency and collimation of the output beam while reducing speckles and improving optical system efficiency.
