Abstract:
Optical hyperfocal reflective systems and methods are provided. One such optical hyperfocal reflective system has an optical substrate; an optical input coupling portion configured to input couple a collimated display image to the optical substrate; and an optical hyperfocal output coupling portion integrated with said optical substrate. The optical output coupling portion includes at least one hyperfocal reflective view port formed from a discrete optical hyperfocal reflector spot integrated with the optical substrate. The discrete optical hyperfocal reflector spot is sized to form a reflected discrete optical spot beam with a diameter at a target area such that a view of a discrete virtual display image portion, as seen by a lens-detector system locatable at the target area, is hyperfocused.
