Paper Abstract

In the diffusion equation approximation, the photon mean trajectory (PMT) and photon path deviation were calculated in relation to scattering medium optical characteristics and methods of measurements (time- or frequency-domain). It was shown that in macroinhomogeneity detection there exists an optimum combination between the spatial resolution (which is defined by photon path standard deviations from PMT) and the value of signal perturbation induced by inhomogeneities. One can evaluate this optimum by the scale matching of photon path rms deviations and macroinhomogeneity size. In turn, such a matching can be realized by the proper choice of the source and detector mutual positions and the values of temporal delay in time-domain or modulation frequency in frequency-domain measurements.
