ABSTRACT
A Monte Carlo model for optical coherence tomography of human skin is proposed. The new model includes importance sampling technique which is designed to suit for the multi-layer human skin, new rules for back scattered photon classification are correspondingly proposed. Based on the new simulation model, we analyzed the focusing of Gaussian beam through skin and the maximum detecting depth of optical coherence tomography. The experimental results show that there exists focus distortion when beam propagates in skin, including focus shift and diffusion. Object lens with greater NA will lower the maximum detecting depth of optical coherence tomography.
