METHOD FOR PRODUCING A COLOUR LASER IMAGE THAT CAN BE OBSERVED IN THREE DIMENSIONS AND DOCUMENT ON WHICH A COLOUR LASER IMAGE THAT CAN BE OBSERVED IN THREE DIMENSIONS IS PRODUCED

摘要

Disclosed are examples of methods and documents of a color laser image observable in three dimensions, which comprises a laserable protective sheet, an array of lenses, colored sub-pixels in column form, wherein a laser beam causes the grey levels to appear in two color laser images observable in three dimensions via stereoscopic effect, and a substrate. The whole, in various implementations, may be laminated. The axes of the columns of sub-pixels and of the lenses may be perpendicular. The laser beam may scan the sub-pixels along the axis of the lenses, in various embodiments.
