Fig. 2From: Hyperspectral imaging as an emerging tool to analyze microplastics: A systematic review and recommendations for future developmentA schematic showing how HSI can be used to analyze MP. A Lambertian reflectance standard is scanned alongside the sample to normalize the spectra according to the light source. The data cube is built of several line scans stitched together as the camera moves from right to left over the MP samplesBack to article page
