Abstract
We have developed a methodology that can be used in reconstruction algorithms to quantify the optical coefficients and the geometrical cross section of a weakly abnormal optical target embedded in an otherwise homogeneous medium. This novel procedure uses different time-dependent point spread functions to analyze the diffusive and absorptive contrasts obtained from time-of-flight measurements. To test the robustness of our reconstruction algorithm, we analyzed two time-resolved data sets obtained in different experimental geometries for a tissue-like phantom. We have shown that results for the two cases are consistent and agree with known values.
