China: Chinese scientists achieve breakthrough in hyper-spectral imaging technology

Chinese researchers have made a big leap in hyperspectral 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 hyperspectral image sensors are equipped with advanced spectral chips and are 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. 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. The hyperspectral device can simultaneously capture geometric information and dozens, even hundreds of spectral bands, making it easy to differentiate between objects that look alike. 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. The achievement has been published in the November 6th edition of the journal Nature.
