ALEXANDRIA, Va., Dec. 16 -- United States Patent no. 12,498,631, issued on Dec. 16, was assigned to BARCO N.V. (Kortrijk, Belgium).

"Method and system for spatial and angular uniformization of light beams" was invented by Dirk L.A. Maes (Bissegem, Belgium), Dries Jan Doornaert (Wevelgem, Belgium) and Daniel Lambot (Leuze-en-Hainaut, Belgium).

According to the abstract* released by the U.S. Patent & Trademark Office: "An imaging projection system that can project uniform illumination onto a light modular while keeping the point spread function small. A Fourier optical system can be inserted between two uniformization structures so that when light passes the through the system, the light output is uniform both in spatial- and angular space....
