Figure Lengend Snippet: (a) Picture of the sliced buffalo tooth under white/flash light illumination. (b) Representative Raman spectra from dentin and enamel side of the tooth. Full-scale Raman images of the buffalo tooth when the band pass filter was tuned to (c) signal peak (Isig) at 960 cm−1, (d) fluorescence reference (Iref) at 880 cm−1, and (e) their difference (Isig-Iref). (f) A laser intensity distribution (Ilaser) image was acquired to obtain (g) the laser intensity calibrated ((Isig-Iref)/Ilaser) mineral distribution image, which is then normalized and re-plotted in (h) 3D format.
