Christopher Leister 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).

  • Composite holographic optical diffuser structure with high frequency overlay and method of fabrication thereof
    Patent number: 9568885
    Abstract: The optical diffuser mastering of the subject invention includes legacy microstructure surface relief patterns, along with smaller ones, overlaid on the larger ones. The characteristic features produced by the present invention will be found useful to eliminate visible structures in/on optical diffusers, such as those used in movie projection screens (utilizing either coherent (i.e., laser-generated) and non-coherent (e.g., lamp-generated) light), head-up displays (HUDs), laser projection viewing, etc., as the present invention produces much sharper images than those afforded by traditional holographic optical diffusers.
