Introduction on Microscopic Imaging Technique Based on CARS

Coherent Anti-Stokes Raman Scattering (CARS) has been an useful method for microscopic analysis of biological molecule, due to its good directionality, the high scattering intensity and the low background noise. In this paper, we review the development of coherent anti-Stokes Raman scattering (CARS) microscopic imaging in the recent years, introduce the application of CARS technology in microscopic imaging theory as well as the suppression of non-resonant background noise in CARS microscopic imaging technology, and show some typical CARS microscopic imaging systems, advantages and fields of CARS microscopic imaging technique are also conclude at the same time.
