调制点光源在光散射介质中的传输规律

Transportation Principles of a Modulated Point Light Source in Optically Scattering Media

报道了调制点光源在光散射介质内部的传输规律.只要调制光信号的中心频率远小于光速与光散射介质吸收系数的乘积且远大于其带宽,那么调制点光源在均匀光散射介质内部的峰值能流率分布与调制信号无关,且与稳定点光源分布相同.

The transportation principles of a modulated spherical light coming from a point light source in an optically scattering media are present.When the central frequency of a modulated light is much larger than its bandwidth and is much lesser than the product of the light velocity and the absorption coefficient in an optically scattering media,the distribution of peak diffuse fluence rate of modulated point light source inside the media is the same as that of stable point light source.Furthermore,the distribution of peak diffuse fluence rate is not related with the modulation signals.
