We describe a compact fiber-optic probe (2 mm outside diameter) that utilizes spatiallyresolved diffuse reflectance for tissue optical property recovery. Validation was performed in phantoms containing Intralipid 20% as scatterer, and methylene blue (MB), MnTPPS, and/or India ink as absorbers. Over a range of conditions, the reduced scattering coefficient was recovered with a root mean square error (RMSE) of 0.86-2.7 cm(-1) (average error = 3.8%). MB concentration was recovered with RMSE = 0.26-0.52 mu M (average error = 15.0%), which did not vary with inclusion of MnTPPS (p=0.65). This system will be utilized to determine optical properties in human abscesses, in order to generate treatment plans tbr photodynamic therapy.
