a Color image of a poster (the logo of Wuhan University), captured with an RGB camera. b Synthesized color image of the poster, obtained using our hyperspectral camera. c The information of the poster acquired with the RGB camera (Left panel: intensity at P1 and P2 in R/G channel) and our hyperspectral camera (Right panel: Spectra at P1 and P2). d Color image of a pattern (Nanjing University) displayed on a micro-LED screen (Unilumin, Umicro0.7), captured with an RGB camera. e Synthesized color image of the pattern, obtained using our hyperspectral camera. f Emission spectra of the green and red LEDs used in the micro-LED screen, measured with a commercial spectrometer. g Spectral images acquired by our hyperspectral camera at five distinctive wavelengths. Each image is normalized with its maximum intensity. Scale bar: 2 mm
