We investigate how to;extract information on the orientational order of molecular bonds in biological samples from penalized coherent anti Stokes Raman, scattering (CARS) and stimulated Raman scattering (SRS) microscopy. Experimentally; the Mean orientation of the molecular angular distribution, as well as its second and fourth orders of Symmetry, are estimated by monitoring intensity signals Under a Varying incident polarization. We provide a generic method of analysis of polarized Signals in both CARS and SRS contrasts, and apply it to imaging Of lipid bonds orientational order in multilamellar vesicles A comparison of the two contrasts in the lipid region around 3000 cm(-1) shows that while SRS allows retrieving pure molecular order information, CARS is generally tainted by a bias from the nonresonant contribution.
