摘要

Abstract

Many exciting terahertz imaging applications

such as non-destructive evaluation

biomedical diagnosis

and security screening

have been historically limited in practical usage due to the raster-scanning requirement of imaging systems

which impose very low imaging speeds. However

recent advancements in terahertz imaging systems have greatly increased the imaging throughput and brought the promising potential of terahertz radiation from research laboratories closer to real-world applications. Here

we review the development of terahertz imaging technologies from both hardware and computational imaging perspectives. We introduce and compare different types of hardware enabling frequency-domain and time-domain imaging using various thermal

photon

and field image sensor arrays. We discuss how different imaging hardware and computational imaging algorithms provide opportunities for capturing time-of-flight

spectroscopic

phase

and intensity image data at high throughputs. Furthermore

the new prospects and challenges for the development of future high-throughput terahertz imaging systems are briefly introduced.
