提出了一种用于光学防伪的偏振编码系统。偏振编码信息可用于安全验证。输入图像的偏振状态可以在使用光学器件来保护信息时提供额外的自由度。偏振编码的输入图像的表达式开发使用琼斯偏振演算。非线性联合变换相关器用于提供光学验证。计算机模拟和光学实验结果表明，所提出的方法的支持。(C)2000年，美国光电仪器工程师学会。[S0091-3286（00）02209-1]。
A polarization-encoding system for optical security verification is proposed. The polarization-encoded information can be used for secure verification. The polarization state of the input image can provide an additional degree of freedom in using optics to secure information. The expressions for polarization-encoded input images are developed using Jones polarization calculus. A nonlinear joint transform correlator is used to provide optical validation. Computer simulations and optical experimental results are shown in support of the proposed method. (C) 2000 Society of Photo-Optical Instrumentation Engineers. [S0091-3286(00)02209-1].
