Abstract

It has been found that a planar glass plate or a rectangular fiber of a suitable size operates as an image guide where an optical wave propagates as a beam in shape and transmits optical image information by repeating total reflection without any excitation of waveguide modes or the self-imaging effect. It is also shown that the image can be magnified by bringing the image guide close to the object. Fundamental properties of this method are analyzed and confirmed experimentally. This method has potential use as a very fine image guide.
