Expected versus calculated effective attenuation coefficients (${\mu }_{\mathrm{eff}}$), offsets, and absorption (${\mu }_{\mathrm{a}}$) and reduced scattering coefficients (${\mu }_{\mathrm{s}}^{\prime }$) for FRED-simulated tissue optical phantoms and the full OIR endoscope. Measurements of phantoms with mean free paths $({\mathrm{mfp}}^{\prime })>0.8\mathrm{mm}$ (outside design limits) are marked with diamonds, while measurements for those with an ${\mathrm{mfp}}^{\prime }<0.8\mathrm{mm}$ are marked by squares.
