Imaging Through Turbid Media with a Nonlinear-Optical Correlation Time Gate

Abstract

We demonstrate the use of a degenerate-four-wave-mixing time gate to allow imaging through turbid media, with potential application to tissue imaging. A near infra-red (NIR), long-pulse Cr+3:Li2SrA1F6 laser is used as the light source, for imaging through clear and turbid media.
