Paper Abstract

Influence of source power on spatial-resolved diffuse reflectance in the region close to the source is studied experimentally. The fiber detector method is performed and the diffuse reflectances from 0.3mm-2.675mm source-detector separations are measured. The source is a 650nm diode laser and its maximum power is 10mw. The experimental result shows that the influence of source power on the diffuse reflectance from a tissue phantom at short source-detector separations is considerable. Also, this influence is found different from the effect of scattering coefficient (μs) and absorption coefficient (μa) on the diffuse reflectance. These results are important to measure the optical parameters of the tissue from the diffuse reflectance.
