ABSTRACT:
A head mounted display system includes focusing optics to focus light from an image source, retro-reflector and beamsplitter, the image source and beamsplitter directing light toward the retro-reflector to focus a real image, and the light reflected from the retro-reflector being directed via the beamsplitter for viewing, thereby to use conjugate optics effectively to place the viewing eye or detector in relation to the image source the same as the relation of the focusing optics to the image source. The retro-reflector may be mounted on a common housing or support with the beamsplitter and focusing optics or it may be remotely located. A method for forming an image using conjugate optics in which light from a source is focused to form a real image at a retro-reflector and is reflected for viewing.
