Optical tomographic imaging requires an accurate forward model as well as regularization to mitigate missing-data artifacts and to suppress noise. Nonlinear forward models can provide more accurate interpretation of the measured data than their linear counterparts, but they generally result in computationally prohibitive reconstruction algorithms. Although sparsity-driven regularizers significantly...
CARS holography combines the chemical selectivity of CARS with the amplitude and phase imaging capability of holography to establish a novel label-free imaging technique. Here, we review CARS holography and its application to biological imaging.
We report experimental image reverse propagation in focusing Kerr media. These results are compared with a linear Zernike filter operation. A method for the measurement of the nonlinear coefficient is derived from these results.
We investigated inline holographic CARS microscopy, in which the reference generated from a nonlinear medium co-propagates with the CARS signal produced from a specimen. We show that this technique has 3D chemical selective imaging capability.
