| Spectral maps made with fiber-based supercontinuum source and synchrotron source. Chemical maps of lipid vesicles in a liver section generated on the 𝜈asymCH2 absorption of lipids at 2920 cm−1. Left to right (a) Optical micrograph of the mapped area. The scale bar indicates 20 μm length. (b) Map recorded with 128 scans at 3 μm×3 μm aperture with the synchrotron source. (c) Map recorded with 16 scans at 3 μm×3 μm aperture with the supercontinuum source. Images Uni Lim / Optica. |
