Patent number: 11906736Abstract: A display has an image generator; a partially transmissive mirror having a curved surface; a beam splitter to reflect incident light toward the curved surface; and an optical image relay that defines a path to relay light to a curved focal surface of a partially transmissive mirror, the curved focal surface is between a curved reflective surface of the partial mirror and the beam splitter. A prism has a folding surface in the optical path for light from the image generator, wherein an aperture stop for the relay lies within the prism. A first plano-aspheric lens, against the prism input surface, guides light from the image generator toward the folding surface; a second plano-aspheric lens, in optical contact against the prism output surface, directs light to the curved focal surface. The relay, curved mirror, and beam splitter form an exit pupil for viewing the scene with a 2D image superimposed.Type: GrantFiled: December 30, 2020Date of Patent: February 20, 2024Assignee: RAYTRX, LLCInventors: David Kessler, Michael H.
