[(a) and (d)] Optimal average absorption (filled circles) and scattering (open circles) efficiencies, and parameters [(b) and (e)]Med[R] and [(c) and (f)]Med[H] of the corresponding optimal distributions as functions of excitation wavelength and tissue refractive index. In (a)–(c), n=1.55; in (d)–(f), λ=850 nm. Solid, dashed, and dotted curves correspond to σ=0.25, 0.5, and 1.0, respectively.
