Optical coherence tomography (OCT) is an emerging non-invasive in vivo biomedical imaging modality capable of performing real time, three-dimensional visualization of tissue morphology at micrometer scale resolution. Coherent Anti-Stokes Raman Scattering (CARS) is a nonlinear spectroscopic technique which provides molecular information due to a four wave mixing process. In combination with a microscope, CARS enables chemical selective imaging by scanning the sample with resolutions in the micrometer range.
We present measurements of the same sample with both techniques by using ultrashort pulse Ti:sapphire lasers.
