Abstract
New curious image-forming action was found experimentally for the Moiré pattern by holding the spacing-gap between two fly's-eye lens plates at a well-adjusted value. The Moire pattern, consisting of many disk-like patterns, can act as many imaging lenses capable of varying the image size and controlling the direction of image in an extremely simple way, i.e. changing the rotation angle of the plates.
Through detailed investigations including the analysis of Moiré lens, it has been clarified that many pairs of two micro-lenses whose focal planes coincide approximately and whose centers displace slightly each other play an important role in this phenomenon.
