The main objective of this project is to research on the fundamentals of THz source arrays for reciprocal and compressive imaging systems. The research builds up on our preliminary investigations of compressive imaging with an all-electronic "Terahertz Digital Light Projector" (T-DLP). In SI-STAR, we propose to extend this extensive research into a new class of THz sources, which can encode THz illumination with an unprecedented diversity toexponentially improve the acquisition speed and quality of reciprocal and compressive sensing. This functionality is enabled by an advanced modulation basis across multiple domains (spatial, temporal, frequency, amplitude) integrated together in a single dynamically reconfigurable silicon integrated source array system-on-a-chip. The project further aims to scale such T-DLPs source arrays into multi-chip systems with large THz illumination apertures and high output power. The proposed research aims to understand the fundamental methods and limitations of implementing such arrays to derive future theoretical and experimental research towards computational THz sensing and imaging.

该项目的主要目的是研究太赫兹源阵列的基本原理，用于互反和压缩成像系统。这项研究建立在我们对全电子“太赫兹数字光投影仪”（T-DLP）压缩成像的初步调查基础上。在SI-STAR中，我们建议将这一广泛的研究扩展到一类新的太赫兹源，它可以以前所未有的多样性编码太赫兹照明，以指数级提高互反和压缩感知的采集速度和质量。该功能通过跨多个域（空间、时间、频率、幅度）的高级调制基础实现，这些域集成在一个动态可重构的硅集成源阵列片上系统中。该项目进一步旨在将这种t - dlp源阵列扩展到具有大太赫兹照明孔径和高输出功率的多芯片系统中。提出的研究旨在了解实现这种阵列的基本方法和局限性，从而为计算太赫兹传感和成像提供未来的理论和实验研究。
