太赫兹（THz）成像是一种快速增长的应用，受到工业需求的推动，包括无害（非电离）安全成像，汽车工业中的多层油漆质量控制，航空航天中的绝缘泡沫非侵入性测试和生物医学诊断。成像系统中的关键部件之一是源和探测器。本文简要介绍了基于共振隧穿二极管（RTD）器件的室温太赫兹成像收发技术。结果表明，RTD技术是一个非常有前途的候选人，实现紧凑，低成本的太赫兹成像系统。
Terahertz (THz) imaging is a rapidly growing application motivated by industrial demands including harmless (non-ionizing) security imaging, multilayer paint quality control within the automotive industry, insulating foam non-invasive testing in aerospace, and biomedical diagnostics. One of the key components in the imaging system is the source and detector. This paper gives a brief overview of room temperature THz transceiver technology for imaging applications based on the emerging resonant tunneling diode (RTD) devices. The reported results demonstrate that RTD technology is a very promising candidate to realize compact, low-cost THz imaging systems.
