*** ABSTRACT 9661475 Kostrzewski This Small Business Innovation Research Phase I project will develop a unique anticounterfeiting method based on optical correlation techniques whose large number of degrees of freedom will ensure extremely high confidence. The proposed methodology uses high density phase encoded labels with 10^30 code possibilities and is an extension of existing optical correlation technology for label verification. Using phase encoding for label verification poses a significant challenge because labels may be presented for verification with unpredictable scale, shift, and rotation. During Phase I, research will be conducted to develop scale, translation, and rotation invariant phase codes together with a flexible reading/processing head that will allow unrestricted placement of labels during the verification process. Scanning or replicating of phase labels will be impossible because of the high optical density of the phase information. An additional feature of the proposed phase encoded labeling is its compatibility with a variety of substrates, including thin foil and plastic in both reflection and transmission modes of operation. Research conducted during Phase I will develop a new tool to fight counterfeit crime. Phase encoded labeling can applied to many security applications like limited access security, ID cards, credit card verification, product label verification systems, and medical records. The production cost of such labels will be in the range of just a few cents per label. ***

***小型企业创新研究第一阶段项目将开发一种独特的基于光学相关技术的防伪方法，其大量的自由度将确保极高的可信度。所提出的方法使用具有10^30码可能性的高密度相位编码标签，是现有标签验证光学相关技术的扩展。使用相位编码进行标签验证是一个重大的挑战，因为标签可能以不可预测的规模、移动和旋转来进行验证。在第一阶段，将研究开发缩放、平移和旋转不变相位代码，以及灵活的读取/处理头，以便在验证过程中不受限制地放置标签。由于相位信息的光密度高，扫描或复制相位标签将是不可能的。所提出的相位编码标签的另一个特征是它与各种基材的兼容性，包括反射和传输操作模式下的薄膜和塑料。在第一阶段进行的研究将开发一种打击假冒犯罪的新工具。相位编码标签可以应用于许多安全应用程序，如有限访问安全性、ID卡、信用卡验证、产品标签验证系统和医疗记录。这种标签的生产成本将在每个标签几美分的范围内。＊＊＊
