Paper Abstract

In this article, a new concept--`limit resolution' is proposed. Limit resolution refers to maximizing the recording resolution of a Fourier holographic point adding to the holographic label to the ultimate limit value of the resolution of the recording materials. After this treatment, the holographic label could not be reproduced, because resolution of the characters, images or security encode matrix stored in a holographic point have reached the ultimate value of the resolution of the material. When the master holographic label is copied, the reconstruction images of the point on the copied sub-holographic label becomes blurred.
