3-D Imaging of Liquid Crystals by CARS Microscopy. B.G. Saar & colleagues used Coherent anti-Stokes Raman scattering (CARS) microscopy to provide three-dimensional chemical maps of liquid crystalline samples without the use of external labels. CARS is an optical imaging technique that derives contrast from Raman-active molecular vibrations in the sample, that offers more rapid chemical characterization without the use of external dyes or contrast agents. The use of CARS to image chemical and orientational order in liquid crystals is demonstrated using several examples, and the limitations and benefits are discussed.
