Researchers at Tianjin University, China, have developed a groundbreaking terahertz (THz) spectroscopy system called SPRATS, which combines high-resolution spectral data capture with near-field spatial detail. This innovative system integrates asynchronous optical sampling (ASOPS) with a micrometer-scale photoconductive probe (PPB), enabling the study of THz resonant structures with enhanced resolution. The system significantly enhances the exploration of functional materials and chemical sensing, representing a pivotal advancement in terahertz photonics and materials research.
