Abstract
An improved image transfer device for transferring light images or the like is formed using 'in-situ' optical waveguides or transfer elements rather than discrete optical fibers. In one embodiment, at least first and second tapered modular spacers are formed with grooves etched therein extending between first and second end surfaces thereof. Each of the grooves has a raised lip structure which enables the spacers to be interconnected in a rigid confronting relationship to produce a plurality of closed tapered channels. Each of the channels is then filled with a conductor to form an optical waveguide for transferring an elemental portion of an image between the first and second end surfaces.
