Coherent anti-Stokes Raman scattering (CARS) holography merges the three-dimensional imaging capability of holography and the high sensitivity and chemical selectivity of coherent anti-Stokes Raman spectroscopy into a new label-free, non-scanning, 3D imaging modality. CARS holography can capture both the amplitude and the phase of a coherent Raman image in a single shot with a laser pulse width limited exposure time, potentially leading to unprecedented 3D imaging speed. Both the off-axis and in-line digital holographic CARS imaging will be discussed. Imaging results of microspheres and live He-La cells will be presented.
