摘要：

A theoretical model is established for finding the resolution of imaging through random media with the first-arriving-light method. With this model analytical mathematical forms of the point-spread function are derived for transillumination and confocal scanning imaging modes combined with the first-arriving-light method. Finally experiments were carried out with the holographic gating technique to demonstrate the validity of the theory. The experimental results show that the first-arriving-light method improves the image resolution by as much as a factor of 20 over the conventional transillumination mode.
