To address the limitations of existing terahertz time-domain imaging systems, we present a new terahertz source array based on plasmonic nanoantenna arrays that offer efficient optical-to-terahertz conversion. As a first proof-of-concept, we use a terahertz time-domain spectroscopy system with the terahertz source array and a single pixel detector to capture multi-pixel hyperspectral terahertz images without requiring raster scanning. We demonstrate that the imaging system can capture both amplitude and phase information by acquiring far-field images of different phase and amplitude objects. The introduced terahertz source array has the potential to realize high-throughput, high-SNR and high-resolution imaging and inspection systems, benefiting from the unique features of terahertz waves.
