Abstract:
1. An optical assembly for retinal projection of electronic image data on a viewing eye having a lens and a retina, the electronic image data being transmitted by a light beam, the assembly having an entrance aperture and an exit aperture and comprising: a focusing lens for receiving the light beam and focusing the light beam into a convergent beam which passes through the entrance aperture, a scanning mirror means for receiving the convergent beam from the focusing lens and scanning the beam along first and second mutually perpendicular axes, a beam splitter for receiving and reflecting the beam from the scanning mirror means, and a concave mirror positioned for receiving the reflected beam from the beam splitter at substantially perpendicular incidence and reflecting the beam towards the eye, the concave mirror being disposed forward of the eye's lens, wherein the light beam has a principal ray that intersects the midpoint of the entrance aperture and is perpendicularly incident on the concave mirror, wherein the beam splitter and the concave mirror image the entrance aperture on the exit aperture which is located in the eye at the position of the eye's lens or slightly behind the eye's lens.
