摘　　要：首次揭示了调制点光源在均匀散射介质中的传输规律。只要调制光信号的中心角频率大大于其带宽且小小于光速与介质吸收系数的乘积,那么调制点光源在均匀散射介质中的峰值能流率分布与稳定的点光源分布相同。The transportation principles of the modulated spherical light coming from a point light source in homogeneous scattering media are present for the first time to our knowledge. When the central angular frequency of the modulated light is much larger than its bandwidth and is much lesser than the product of the light velocity and the absorption coefficient in the media, the distribution of peak value of the diffuse fluenee rate of modulated light within the media is the same as that of a stable point light source.
