Fiber optic image shape converter and method of making the same
First Claim
1. The method of making a fused glass clad glass image transporting and shape converting device from a section of fused glass optical fiber conduit having a multiplicity of juxtapositioned individually flexible light-conducting fibers all rigidly fused together with a leachable glass matrix and said fibers being substantially indentically geometrically patterned at least at opposite ends of said conduit wherein said method comprises the steps of:
- leaching said glass matrix away from said fibers adjacent a first end of said conduit;
replacing said leached matrix with a non-leachable bonding material;
covering the opposite second end of said conduit with a protective cap of non-leachable material to protect the fused glass clad glass integrity thereof;
leaching said matrix away from said fibers throughout the extent of said conduit between said non-leachable bonding material and said cap to render said fibers of said conduit and said conduit as a whole intermediately flexible;
separating said fibers into a plurality of groups at said first end of said conduit each group being of a preselected size and shape by cutting between said fibers longitudinally thereof through said non-leachable bonding material;
assembling said groups of fibers into a predetermined pattern differing in geometrical configuration from that of said first end of said conduit; and
removing said cap at any preselected stage of said method following said last mentioned leaching step.

Abstract
A fiber optic image transporting device for converting the shape of optical images directed thereinto. The device is formed of an initially rigid multifiber conduit having a leachable fiber connecting matrix. The matrix is removed from one end of the conduit and replaced with a fiber bonding resin. The intermediate portion of the conduit is then leached, keeping its opposite end intact as one image transmitting face of the device, and the resin bonded end is cut into sections of predetermined shapes and sizes which are reassembled to form a differently shaped second image transmitting face.
