摘　　要：在分析传统光学相位编码技术特性的基础上,提出了一种可实用化的光学相位防伪掩模设计方法。该方法采用二维条码编码技术,将用于防伪的文本或图像信息编码为二维条码,然后基于传统相位编码技术将该二维条码编码为光学相位防伪掩模。采用较低量化阶数的防伪掩模进行解码后,利用图像形态学相关算法成功恢复出原二维条码的准确编码信息,进而通过二维条码解码得到原始的文本和图像。该设计方法不但有效解决了传统光学相位编码方法的物理实现难题,而且还具有安全性高、成本低、防伪性能好等优点,为推动新一代光学防伪掩模的市场化应用提供了有效的技术途径。This paper proposes a practical design method for an optical phase anti-counterfeiting mask based on the analysis of the characteristics of traditional optical phase-coding technology.A two-dimensional(2D)barcode is used to encode text or image information for anti-counterfeiting into a 2D barcode,and then the 2D barcode is encoded into an optical phase anti-counterfeiting mask based on the traditional phase-coding technology.After decoding the anti-counterfeiting mask with a lower quantization order,accurate encoding information of the original 2D barcode can be successfully restored using image morphology-related algorithms,and the 2D barcode is decoded to obtain the original text and image.The proposed design method not only effectively solves the physical implementation problems of traditional optical phase-coding methods but also exhibits the advantages of high security,low cost,and good anti-counterfeiting performance,which provides an effective technical approach to promote market-oriented applications of new-generation optical anti-counterfeiting masks.
