| Abstract
| - To improve quantification of optical properties in highlyscattering and absorbing samples, time-correlated singlephoton counting measurements were analyzed usingquantities related to the correlation dimension. Photontime-of-flight (TOF) distributions were collected in reflection and transmission optical configurations from samplesmade of cream and water-soluble dye (0 < μa< 0.05mm-1; 100 < μs< 250 mm-1). It was found thatabsorption and scattering properties of samples could beaccurately quantified from information used to determinethe correlation dimension. Scattering coefficients wereestimated with less than 4% error for both optical configurations. Absorption estimates were made with CVs of7.5 and 9.6% for reflection and transmission, respectively. Overall, fractal dimension analysis of TOF distributions provides a simple method of determining the opticalproperties of a sample.
