摘　　要：提出了一种基于微透镜列阵三维成像的防伪标签设计及制备方法。建立了基于微透镜列阵的三维成像模型，开展了三维成像系统关键部件一微结构图像阵列和高精度微透镜阵列的生成及制备技术的研究。针对所要获取的三维立体影像，利用3DMAX软件对三维成像结构进行设计，采用微细加工技术对三维成像结构中所需的微结构及高精度微透镜列阵进行制备。最终成功制备了高分辨率防伪标签。A new method of designing and manufacturing of anti-counterfeiting labels, which based on the three- dimensional imaging technique employing micro-lens array has been proposed. The three-dimensional imaging model is scientifically built. The structure designing and fabrication of the three-dimensional imaging key elements, the sub- image and micro-lens array, are carried out. According to the three-dimensional image, the three-dimensional imaging structure is designed with 3DMAX, after all of that, the micro structure and high precision micro-lens array of the three-dimensional structure are fabricated by micro machining technology. Finally, the high resolution anti- counterfeiting label is obtained.
