Fig. 2.

Diffuse reflectance $R_{\mathrm{d}}$ and total transmittance $T_{\mathrm{t}}$ spectra of Asian (a) epidermis, (b) dermis, and (c) subcutaneous fat averaged over the 15, 20, and 15 samples, respectively. The (i) upper and (ii) lower figures show $R_{\mathrm{d}}$ and $T_{\mathrm{t}}$, respectively. The shaded area represents the standard deviation.
