摘要
描述了一种利用光学全息及半色调技术的二维条码的编解码方法。 与传统的二维条码编码方法相比, 该方法利用光学全息的方法对信息进行编码和解码,避免了传统二维条码复杂的编解码流程,而且 可以利用全息固有的特征提高其数据存储能力和纠错能力。此外,在编码过程中引入半色调技术减少二维条码在打印 过程中的信息丢失。根据上述原理,实现了全息二维条码的编解码,计算仿真和实验均证明了该方法的可行性。
Abstract
A new method for generation of two dimensional bar code is proposed. Compared with traditional bar code, the new kind of bar code is produced by holography. It not only minimizes complexity of encoding, but also improves ability of volume of information and error correction in bar code by taking advantage of the inherent characteristics of hologram. In addition, by the half-tone technique, it minimizes losing of information of printing process. The simulation and experiment results prove the validity of the method.
