Hyperspectral mapping of orange fluorescence spiral-shaped polyethylene block measured under 400 nm laser excitation. (a) Original spectral stack collected across the scanned area and (b) 2D spectral map constructed by integrating the selected ROI in the fluorescence band, using the ROI imaging tool in PyMca. (c) Fluorescence spectrum with the defined ROI used for constructing the 2D spectral mapping. (d) Digital photograph of the spiral-shaped polyethylene block.
