Multispectral Terahertz Imaging System Incorporates Neural Network
LOS ANGELES, Jan. 29, 2024 — Researchers at UCLA have developed a focal plane array (FPA) capable of supporting real-time multispectral terahertz (THz) video in 3D. According to the team, led by UCLA professors Mona Jarrahi and Aydogan Ozcan, this is the first time a terahertz imaging system has been able to achieve real-time multispectral imaging with video capability while maintaining a high signal-to-noise ratio (SNR). The THz spectrum is desirable due to its ability to penetrate opaque materials and provide
