摘要: The invention belongs to the technical field of anti-forgery, which aims provide a dynamic reproduction method for grating encrypted message. message specifically comprises following steps: manufacturing group continuously changed images into diffraction patterns conceal original image information by encryption; combining taking as optical plane elements; on logo (such laser holographic logo) plastic substrate in an embossment structure form, wherein human eyes cannot identify patterns; and elements obtain continuous encryption information. When is carried out, beam scans moves combined elements, reproduced can dynamically reproduce images. For example, picture, rotating letter A converted combination 1 manufactured anti-fake 2. 1, reflected aluminium coating, process be seen from white paper after put light path light.
