color="#000000">Chemical imaging is an emerging analytical tool which
offers dynamic, non-invasive, and compositional analysis of chemically
heterogeneous materials. To overcome the low signal level problem
encountered in Raman chemical imaging, coherent Raman scattering (CRS)
microscopy techniques have been developed. Here we describe latest
advances in high-speed high-resolution chemical imaging based on
coherent anti-Stokes Raman scattering (CARS) and stimulated Raman
scattering (SRS) modalities. Specific examples will be presented
including imaging of lipid bodies of cultured cells, explanted
tissues, live animals as well as chemical imaging of pharmaceutical
solid dosage forms. The preliminary results on development of
optically heterodyned Raman-induced Kerr-effect (OHRIKE) modality will
be discussed.</font></div>
