About

Pengfei Qi is a rising innovator in the field of terahertz (THz) imaging, with a focused research agenda on advancing high-speed, non-destructive evaluation and three-dimensional sensing technologies. His most cited work, "High-speed non-spatial scanning terahertz three-dimensional imaging" (2025), tackles a critical bottleneck in the field: the prohibitive cost and limited spectral and volumetric resolution of conventional THz focal plane arrays. By pioneering a non-spatial scanning approach, Qi has demonstrated a method that significantly accelerates volumetric data acquisition while preserving the unique spectral fingerprinting capabilities of THz radiation—key for security screening, biomedical diagnostics, and materials characterization. Though early in his career, this contribution has already garnered attention for its potential to democratize THz imaging systems. His research bridges the gap between fundamental photonics and practical instrumentation, offering a pathway toward real-time, high-resolution THz imaging without the expense of traditional arrays. As a researcher committed to solving real-world sensing challenges, Pengfei Qi is establishing himself as a promising voice in the next generation of terahertz engineering.
