Abstract

An optical property of a turbid medium to be tested is determined. A light measurement device (15) is used to obtain photon distribution data regarding a parameter from light exiting from the medium (one example is the time-of-flight intensity distribution). A fractal element analyzer (16) receives the distribution data and produces a count of a number of points of the distribution in a partition element for each data point in the distribution, for each of the partition element sizes. An optical property estimator (18) receives the count and compares characteristics of a relationship of the optical property of the medium to be tested to characteristics of a relationship of the optical property obtained for a plurality of calibration media (having known optical properties) to output a value for the optical property of the medium.
