In contrast, off-the-shelf smartphone camera sensors are potentially hyperspectral in nature, meaning that each pixel is sensitive to far more spectral bands. Now scientists have found a simple way for any conventional smartphone camera to serve as a hyperspectral sensor—by placing a card with a chart on it within its view. By extracting it, we can turn everyday photography into science.”Using a smartphone camera and a spectral color chart, researchers can image the transmission spectrum of high-end whiskey, thus determining its authenticity. Previous research has pursued a number of different ways to recover spectral details from conventional smartphone RGB camera data. This strategy can extract hyperspectral data from raw images with a sensitivity of 1.6 nanometers of difference in wavelength of visible light, comparable to scientific-grade spectrometers.
