Abstract

Frequency domain technique has been increasingly used for near-infrared spectroscopy and theoretical analysis of frequency domain measurement becomes important. Recently a new Monte Carlo algorithm to directly predicts the modulation and phase for frequency domain measurement was proposed. In order to apply this algorithm to heterogeneous scattering medium, a statistically accurate procedure for the photon passing the boundary of different medium is necessary. In this study, frequency domain Monte Carlo algorithm for heterogeneous medium including non scattering clear region is investigated. The modulation and phase shift predicted by frequency domain Monte Carlo is compared with the Fourier transformation of TPSF predicted by time domain Monte Carlo algorithm.
