摘要：
A system for imaging an object in or behind a highly scattering medium includes a light source for illuminating the highly scattering medium with a beam of light. The light emerging form the highly scattering medium consists of a ballistic component, snake-like component and a diffuse component. A 4F Fourier imaging system including a Fourier spatial filter located at 2F is used to form a time gated image of the emerging light, the time gated image consisting primarily of the ballistic component and the snake-like component.
