Optical imaging through turbid media using a degenerate-four-wave mixing correlation time gate

摘要

This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The authors have demonstrated 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(sup +3):Li(sub 2)SrAlF(sub 6) laser was used as the light source (during most the project) for imaging through clear and turbid media. Preliminary experiments were also carried out with a continuous diode laser.
