In the field of the optical fiber communication s!-stems. the Planar Lightwi\e Circuits (PLC) are coming into practical use as passive optical parts such as couplers. splitters. filters. In addition, LD arra!'s and PD arrays arc now under de\dopmeiit for tlie optical interconnection that is used for super high-speed computers or large-scale switchboards.(More)
-Basic concepts defined for understanding of optical illusions include a position-dependent PSF (point spread function) and an assumed measure of fixation over the pattern plane. An exact simulation of the famous Hering's illusion has been carded out by employing the position-dependent PSF. Reasonable understanding of the Mueiler-Lyer's and Poggendorff's(More)
