Terahertz (THz) radiation underpins many next-generation technologies and advances in materials science, but current THz spectroscopy methods cannot deliver both high spectral and spatial resolution simultaneously. Now, researchers have addressed this challenge by developing a novel methodology called spatially resolved asynchronous-sampling THz spectroscopy (SPRATS). Their system combines two existing THz measurement techniques to achieve micrometer-level near-field imaging and ultra-high spectral resolution, enabling the characterization of advanced THz resonant structures. SPRATS represents a transformative advancement in terahertz spectroscopy, bridging critical gaps between far-field and near-field methodologies while establishing new benchmarks for resolution and accuracy. This technology opens possibilities across multiple disciplines, including materials science, biomedical sensing, integrated photonics, and fundamental physics research.
