Abstract:
The invention is concerned with a hidden image product, an identification device which shows the hidden image information, an identification system, the produce method of the produce and the identification equipment, the identification equipment contains a single layer or multi-layer lens with the specified array micro-structure. The produce contains the array pixels with same-level array-distance corresponding with the identification equipment array micro-structure. The selected area of the array pixels and the identification equipment array micro-structure has the entirely or partly controlling phase excursion, shows the micro-structure or the hidden image in the pixel when the array of pixels of the product or the array of the identification equipment array micro-structure is superposition or spacedly squaring with distance. The invention overcomes the low anti-false precision and the inconvenience of the existing hidden image identification technique.
