标题： Physics-guided Terahertz Computational Imaging

摘要： 可视化物体内部的信息是从物理、化学、生物到计算领域连接世界的一个持久需求。 在所有断层扫描技术中，太赫兹（THz）计算成像展示了其独特的传感特性，能够在非破坏性、非电离和非侵入的方式下数字化多维物体信息。 应用现代信号处理和基于物理学的模态方法，太赫兹计算成像系统如今已在工业检测、安全检查、化学检测和无损评估等多个应用领域得到推广。 本文综述了太赫兹计算成像模态在系统配置、波传播与相互作用模型以及基于物理学的算法以数字化成像物体内部信息方面的最新进展。 进一步讨论了几种基于多维太赫兹信号的图像恢复和重建问题，从信号处理的角度提供了材料数字化、功能属性提取以及多维成像器利用之间的交叉链接。 显示英文摘要

摘要： Visualizing information inside objects is an ever-lasting need to bridge the world from physics, chemistry, biology to computation. Among all tomographic techniques, terahertz (THz) computational imaging has demonstrated its unique sensing features to digitalize multi-dimensional object information in a non-destructive, non-ionizing, and non-invasive way. Applying modern signal processing and physics-guided modalities, THz computational imaging systems are now launched in various application fields in industrial inspection, security screening, chemical inspection and non-destructive evaluation. In this article, we overview recent advances in THz computational imaging modalities in the aspects of system configuration, wave propagation and interaction models, physics-guided algorithm for digitalizing interior information of imaged objects. Several image restoration and reconstruction issues based on multi-dimensional THz signals are further discussed, which provides a crosslink between material digitalization, functional property extraction, and multi-dimensional imager utilization from a signal processing perspective.
