METHOD FOR PRODUCING MULTIPLE-OBJECT IMAGES AND AN OPTICAL FILM FOR IMPLEMENTING SAID METHOD

摘要

The invention relates to a method for producing multiple-object images, in particular large-format multiple-object images, and to optical films used in this method. For implementing the method for producing a multiple-object image (1), use is made of an optical film (2) comprising an array of superlenses (3) formed by two arrays of positive microlenses consisting of an optically transmissive material which are fixed relative to one another, wherein in at least one direction along the surface of the optical film (2), the number of superlenses (3) is from 0.5 to 225 per inch, and in the focal plane (9) of each of the superlenses (3) or equidistant to the surface of the optical film (2) at a distance from the focal plane (9) of each of the superlenses (3) which is smaller than the focal distance f of each of the superlenses (3), an array (10) of static or dynamic elemental images is arranged. In order to produce a multiple-object image (1) between an observer (11) and the optical film (2), an array of elemental images (10) is arranged between the focal plane (9) of the superlenses (3) and the optical film (2).
