Apparatus and method for obtaining images using coherent anti-stokes Raman scattering

摘要

Disclosed is an apparatus and method for obtaining images using coherent anti-stokes Raman scattering. The apparatus for obtaining images using coherent anti-stokes Raman scattering according to the present invention comprises: a pump light source (401) and a stokes light source (402) that irradiate pump light and stokes light on a sample (S) to generate anti-stokes light having anti-stokes frequency; a reference light source (410) that generates reference light; and an image obtaining unit (430) that obtains the images of the sample using a change in phase of the reference light due to a change in the refractive index of the sample in the vicinity of the anti-stokes frequency. Thereby, the present invention provides an apparatus for obtaining images using coherent anti-stokes Raman scattering that is not affected by non-resonant background signals, that has strong resistance against noise even for weak signals, and that has excellent sensitivity and resolution.
