Abstract:

A method and apparatus for imaging an object that is part of, embedded in or viewed through a scattering medium is provided. A first broadband beam generator, such as a broadband pulse laser, provides a first broadband beam. A second broadband beam generator, such as a Raman Stokes generator disposed to receive the first broadband beam, generates a second broadband beam capable of correlation with the first broadband beam. A coherent anti-Stokes Raman scattering material is disposed to receive the second broadband beam after dispersion in the scattering medium. A variable delay path also illuminates the coherent anti-Stokes Raman scattering material with the first broadband beam. The coherent anti-Stokes Raman scattering material produces an anti-Stokes beam which contains an extracted image of an object in the scattering medium, which image is recorded on a photodetector.
