Peter Lude has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • High dynamic range projection with multiple numerical aperture illumination
    Patent number: 9854212
    Abstract: A projection system includes first and second illumination sources and a homogenizer component. The first illumination source has a first numerical aperture value. The second illumination source has a second numerical aperture value lower than the first numerical aperture value. The homogenizer component on the illumination path is configured to receive light from both the first and second illumination sources. A projection lens in the imagining path is configured to receive an image data stream that includes a sequence of image frames having an image frame period. The first and second illumination sources are configured for modulation at a rate equivalent to the image frame period. One or more active irises may perform the modulation.
