Abstract Fourier single-pixel imaging (FSPI) technique can encode a real two-dimensional scene to one-dimensional time-varying light intensity sequences traveling in the free space. In this work, FSPI technique with weighted light source is regarded as a carrier of multi-dimensional information while capturing the object scene using a lens-free photodetector, and can carry visible and invisible optical information simultaneously utilizing a novel spectrum division multiplexing technique. A wavelength division multiplexing technique is adopted to improve the channel capacity as well, in which a total of six watermarks are embedded once. More importantly, our scheme successfully demonstrates that triple information (host scene, visible, and invisible optical information) can be transmitted and retrieved with high fidelity in four noisy environments including external attack, environmental interference light, thick and dynamic scattering.

使用单像素检测器在嘈杂环境中嵌入和传输多维光学信息

摘要 傅里叶单像素成像 (FSPI) 技术可以将真实的二维场景编码为在自由空间中传播的一维时变光强序列。在这项工作中，使用加权光源的 FSPI 技术在使用无透镜光电探测器捕获物体场景时被视为多维信息的载体，并且可以利用新颖的光谱分复用技术同时携带可见光和不可见光信息。也采用波分复用技术来提高信道容量，其中一次嵌入总共六个水印。更重要的是，我们的方案成功证明了三重信息（宿主场景、可见、
