title: Wide-field vibrational phase imaging.
abstract: We propose and implement a wide-field microscopy method to retrieve the real and imaginary part of a field emitted by coherent and resonant molecular scatterers. The technique is based on wave-front sensing and does not require the use of any reference beam. We exemplify its ability in wide-field coherent anti-Stokes Raman scattering imaging and retrieve the complex anti-Stokes field while spectrally scanning a molecular vibrational resonance. This approach gives access to the background-free Raman spectrum of the targeted molecular bond.
