Coherent Anti-Stokes Raman Scattering Holography: Theory And Experiment

We review coherent anti-Stokes Raman scattering (CARS) holography as a non-scanning, label-free, three-dimensional imaging technique. The theory of CARS and its integration with digital holography is explored. We then discuss the experimental implementations of CARS holography including in-line and off-axis modalities and the demonstrations of three-dimensional imaging, chemical selectivity and the application of CARS holography to biological imaging.
