摘要

The present invention is concerned with an imaging system for the self- imaging of objects, using optical waveguides comprising reflecting boundary surfaces, and satisfying the imaging condition L&lgr; = 4hN. sub.&mgr; W.sup.2.sub.eq, wherein L is the axial distance between the object and the self-image, W.sub.eg is a typical transverse dimension of the waveguide having an effective refractive index N.sub.&mgr;, and . lambda. is the operational wavelength, and h is an integer for single imaging and not an integer for multiple imaging.PPMany embodiments of dielectric thin film waveguides are described which have the purpose of self-imaging very small objects with good levels of resolution. Magnification or reduction by means of the imaging system are also provided for.
