Paper Abstract

It is possible to delineate the contribution of surface layers from the bulk optical properties of the medium by using selective adjacent distances of the detection fibers in an optical probe with small source-detectors distances. Using an optical probe with small source-detector separation, the measurement at r < 0.8 mm carries more information about the surface layers, the measurement at greater r > 1.4 mm is dominated by optical properties of deeper layers and is less sensitive to differences in surface optical properties.
