By combining an innovative optical technology called Metalens with cutting-edge image processing technology based on AI, NTT can acquire hyperspectral images, which are detailed color information images, simply by replacing the lenses of ordinary digital cameras with Metalens. Developed imaging technology. This technology eliminates the need for the structures and mechanisms unique to hyperspectral cameras, which have led to larger cameras and reduced resolution and frame rate, making it possible to capture video with high-resolution hyperspectral images.
