本文提出了一种新的方法，光学验证解码图像通过单次拍摄成像没有参考波使用的二进制强度模式。基于双随机相位编码（DRPE）应用没有参考波的光学成像，并且记录的强度图案被进一步压缩，其仅包含两个量化级别（即，0和1）。在解码过程中，迭代相位恢复算法的发展和应用。结果表明，由于设计的光学编码策略仅使用一个二进制强度图案，解码图像在视觉上不呈现输入信息，并且进一步进行光学验证以有效地验证解码图像。为开发的光学系统建立了额外的安全层，因为光学验证是基于光学编码系统进行的，而无需直接观察来自解码图像的输入信息。这是第一个报告中使用的只有一个1位的强度图案的DRPE系统的基础上单次拍摄成像没有参考波通过光学相关的安全验证。
In this paper, a novel method is proposed to optically verify the decoded images via single-shot imaging without reference wave using a binary intensity pattern. Optical imaging without reference wave is applied based on double random phase encoding (DRPE), and the recorded intensity pattern is further compressed, which contains only two quantization levels (i.e., 0 and 1). During the decoding, an iterative phase retrieval algorithm is developed and applied. It is demonstrated that decoded images do not visually render the input information due to the designed optical encoding strategy using only one binary intensity pattern, and optical verification is further conducted to effectively verify the decoded images. An additional security layer is established for the developed optical system, since optical verification is conducted based on optical encoding systems without direct observation of input information from the decoded images. It is the first to report the use of only one 1-bit intensity pattern in the DRPE system based on single-shot imaging without reference wave for secured verification via optical correlation.
