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 (μ_s) and absorption coefficient (μ_a) on the diffuse reflectance. These results are important to measure the optical parameters of the tissue from the diffuse reflectance.
