China - November 26, 2024 Chinese scientists achieve breakthrough in hyper-spectral imaging technology (Voice_over) Chinese researchers have made a big leap in hyper-spectral imaging technology, which is used in sensors to rapidly and accurately recognize an object in a complex environment. Developed by researchers at the Beijing Institute of Technology, the broadband hyper-spectral image sensors are equipped with advanced spectral chips and powered by AI algorithms. In one demonstration, researchers showed how the technology can be used to differentiate between a silicone face mask and a real human face. (Sound_bite) Wang Zhen, PhD student, BIT Center for Scientific Exploration in Complex Environment (BISC): "Here is a facial mask made from silicon rubber that has a fundamental difference in spectral properties compared to our real human face. Through this difference, we can accurately detect and identify disguises." (Voice_over) The hyper-spectral device can simultaneously capture geometric information and dozens, even hundreds, of spectral bands, making it easy to differentiate between objects that look alike. (Sound_bite) Bian Liheng, Professor, BIT Center for Scientific Exploration in Complex Environment (BISC): "To capture spectral information across the full spectrum—from the three primary colors to hundreds of spectral bands—we need more materials for broadband spectral modulation. That's why we have developed over 100 materials that can modulate the incoming light across a broad spectrum. This enables us to collect light from hundreds of spectral bands onto a chip. When combined with intelligent algorithms, this chip-based technology integrates both hardware and software to form a powerful function." (Voice_over) The achievement has been published in the November 6th edition of the journal Nature. [Restriction: No access Chinese mainland]
