Compressive sensing is a powerful tool to efficiently acquire and reconstruct an image even in diffuse optical tomography (DOT) applications. In this work, a time-resolved DOT system based on structured light illumination, compressive detection, and multiple view acquisition has been proposed and experimentally validated on a biological tissue-mimicking phantom. The experimental scheme is based on two digital micromirror devices for illumination and detection modulation, in combination with a time-resolved single element detector. We fully validated the method and demonstrated both the imaging and tomographic capabilities of the system, providing state-of-the-art reconstruction quality.
压缩感知是一种强大的工具，即使在扩散光学层析成像（DOT）应用中，也能有效地获取和重建图像。在这项工作中，我们提出了一种基于结构光照明、压缩检测和多视图采集的时间分辨DOT系统，并在生物组织模拟体模上进行了实验验证。该实验方案基于两个数字微镜器件进行照明和检测调制，并结合一个时间分辨单元素探测器。我们充分验证了该方法，并展示了系统的成像和层析成像能力，提供了最先进的重建质量。
