Paper Abstract

We compare two methods to evaluate the time dependence in Monte Carlo simulations of photon migration: sampling of the pulse response in time and evaluation of the transfer function at discrete points in the frequency domain. We show that these two methods differ in accuracy due to quantization and sampling errors, while the statistical error is the same for both methods. From our analysis we also derive alternative techniques to sample the time-domain pulse response with reduced quantization and sampling error.
