Abstract
An image display system includes: an image projector including a mirror optical element for forming an exit pupil for viewing an image at a viewing location; a viewer eye position detector for generating a signal representing the position of a viewer's eyes relative to the location; and a control system responsive to the signal for providing relative motion between the viewer and the image projector to maintain the viewer's eyes at the exit pupil.
Claims30
An image display system, comprising:
- a) an image projector including a mirror optical element for forming an exit pupil for viewing an image at a viewing location;
- b) a viewer eye position detector for generating a signal representing the position of a viewer's eyes relative to the location;
- and
- c) a control system responsive to the signal for providing relative motion between the viewer and the image projector to maintain the viewer's eyes at the exit pupil;
- wherein the image display system further includes an adjustable rest for positioning a viewer relative to the image projector and the control system adjusts the position of the adjustable rest.
