An active hyperspectral imaging system based on a multi-LED light source
Abstract：Hyperspectral imaging (HSI) is a popular method of substance identification and mapping in many fields. Light-emitting
diodes (LEDs) can be introduced as an active light source, which have been widely used with the distinct advantages of small size,
low energy consumption, long lifetime, and fast switching. In this paper, we propose an active HSI system that is based on a multi
wavelength LED-array light source. This LED-based HSI system has a simple and stable configuration, without the complex
dispersive spectrometer and mechanical scanning device. The proposed HSI system has been validated using the standard color
checker, showing a reliable spectral performance. Moreover, the spatial-spectral information of Chinese paper-cuttings has been
successfully extracted, which indicates the great potential in practical applications.
