(a) Diffuse reflectance measured in the LGLSI geometry (blue line) and the 3 mm SDS DRS geometry (red line) in the wavelength range from 650 to 1000 nm for the liquid phantom LP_a, and their respective fitting results (LGLSI: squares, 3 mm SDS DRS: triangles). (b) μa and (c) μs' spectra of LP_a recovered using the LGLSI geometry (blue dashed lines) and the 3 mm SDS DRS (red dashed lines). The benchmark spectra (black lines) were determined using the IAD method.
