3-DIMENSIONAL TEMPORAL IMAGE-RECONSTRUCTION OF AN OBJECT HIDDEN IN HIGHLY SCATTERING MEDIA BY TIME-GATED OPTICAL TOMOGRAPHY

Three-dimensional images of an object hidden in a thick highly scattering medium were reconstructed from sets of two-dimensional images obtained from a time-gated optical imaging system. CCD images were combined by use of the backprojection algorithm to render a three-dimensional picture on a personal computer monitor. The image quality varied with the delay of the Kerr gate system. When the reconstructions were produced by using the early light, submillimeter resolution was achieved with the optical time-gating tomographic technique.
