Abstract

The three techniques of CW, time-gated, and frequency modulation measurements are examined and compared for their ability to provide clues to the macroscopic optical properties of multilayer random media. For each illumination scheme, a simple algorithm is described which is capable of identifying important parameters such as the ratio of macroscopic absorption cross-sections across layer boundaries, and the depth of boundaries in two- and three-layer media. The algorithms are developed by consideration of data from Monte Carlo simulations, and in the case of the time- and frequency-domains, are tested by using them to analyze experimental data.
