Abstract

In this paper, the mathematical equation of the flatheaded Gauss laser pulse is given. Based on the Diffusion equation, by using the Gauss laser pulses in different pulse width and shapes for the incident light sources, we get the simulations of the time-resolved reflectance, transmittance and their pulse shapes in the boundary condition of homogeneous slab. The simulation results show that the ultra short Gauss laser pulse is widened by the diffusive scattering, in addition, the various medium parameters have different influence on the reflected and transmitted intensity of the laser pulse. In the boundary condition of homogeneous slab media, the interactions between the absorption coefficient, the scattering coefficient, the anisotropy coefficient, the pulse width and the pulse shape of the incident laser pulse all have been investigated. This study is useful for the optical noninvasive measurement of the optical properties of tissue.
