漫射光学成像探测深层活组织，实现结构、功能、代谢和分子成像。最近，由于空间光调制器的可用性，宽视场定量漫射光学技术已经实现，这在很大程度上得益于结构光方法。这样的实现有助于在快速采集速度下对厚组织和深层组织的深度分辨光学和生理特性进行量化和表征。我们总结了利用结构光的三种主要技术的现状和应用：空间频域成像、光学层析成像和单像素成像。介绍了空间频域成像的原理、测量和分析。然后，总结了先进的理论、处理和成像系统。综述了生理测量在临床前和临床中的应用。介绍了层析成像的一般理论和方法发展，以及包括荧光分子层析成像在内的应用。最后，综述了单像素成像方法及其应用的最新进展。
Diffuse optical imaging probes deep living tissue enabling structural, functional, metabolic, and molecular imaging. Recently, due to the availability of spatial light modulators, wide-field quantitative diffuse optical techniques have been implemented, which benefit greatly from structured light methodologies. Such implementations facilitate the quantification and characterization of depth-resolved optical and physiological properties of thick and deep tissue at fast acquisition speeds. We summarize the current state of work and applications in the three main techniques leveraging structured light: spatial frequency-domain imaging, optical tomography, and single-pixel imaging. The theory, measurement, and analysis of spatial frequency-domain imaging are described. Then, advanced theories, processing, and imaging systems are summarized. Preclinical and clinical applications on physiological measurements for guidance and diagnosis are summarized. General theory and method development of tomographic approaches as well as applications including fluorescence molecular tomography are introduced. Lastly, recent developments of single-pixel imaging methodologies and applications are reviewed.
