Tsinghua University Team Led by Academician Dai Qionghai Develops SpectraTrack for Megapixel, Thousand‑Channel, High‑Speed Dynamic Hyperspectral Imaging

Hyperspectral imaging captures both spatial information and continuous fine spectral fingerprints of targets, acting as a core technology for environmental remote sensing, industrial inspection, vehicle‑mounted perception and life science detection. Conventional snapshot hyperspectral imaging is limited by the trade‑off among spatial resolution, frame rate and spectral channel count, failing to support real‑time monitoring of high‑speed dynamic scenes.Led by Academician Dai Qionghai from Tsinghua University, the team proposed a novel computational imaging architecture named SpectraTrack. Breaking limitations of traditional spectroscopic systems, it achieves integrated acquisition of megapixel resolution, hundred‑fps frame rate and thousand‑level spectral channels, providing high‑performance solutions for dynamic target tracking, real‑time remote sensing and high‑speed industrial non‑destructive testing.
