Influences of diffusive reflection intensity and pulse shaping of ultra-short laser on turbid media
PACS: 42.65.-k
Abstract
The influences of the absorption μ a, the scattering μ s and the anisotropy coefficient g on the optical properties of ultra-short pulse in turbid media has been simulated that is based on the diffusive approximation theory. The laser pulse intensity will be attenuated and the diffusive scattering pulse shape will be widened in the turbid media. The various medium parameters have different influence on the reflection of the laser pulse. The intensity loss of the diffusive reflection light is obtained when the μ a and μ s is increased in turbid media. The pulse width is rapidly increased of the diffusive reflection pulse far away from the incident point and the same time the pulse time are delayed have been numerical simulated in the boundary condition of semiinfinite homogenous media.
