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