Imaging with Ultra Fast Light Pulse in Scattering Media using the DRTS Method

Abstract

We demonstrate 3D-view imaging in strongly scattering media, with embedded absorbing objects, illuminated with ultra-fast photon pulse. The time-resolved photon propagation process was simulated using the Dynamic Radiative Transfer System (DRTS). Three-dimensional views were obtained at various camera positions using scattered photons. By judiciously selecting time-frame imaging and single-angle directional detection, we extract clean images of the embedded objects. Our modeling method, optical media parameters and image extraction techniques can be useful in biological imaging applications in tissues, where scattering is the dominant optical propagation process. These results have the potential of accomplishing a full 3D reconstruction of the volume of interest.
