Patent 10386558 was granted and assigned to Imagineoptix Corporation on August, 2019 by the United States Patent and Trademark Office.
A polarization conversion system includes a geometric phase element and a retarder element. The geometric phase element has optical anisotropy with local optical axis orientations that vary non-linearly in at least one dimension along a surface thereof. The retarder element is arranged to receive light output from the geometric phase element. Related systems and methods are also discussed.
