Quantitative image analysis of broadband CARS microscopy hyperspectral images of polymer blends

We demonstrate that broadband coherent anti-Stokes Raman scattering (CARS) microscopy can be very useful for fast acquisition of quantitative chemical images of multilayer polymer blends. Since a raw CARS signal results from coherent interference of resonant Raman and nonresonant background, its intensity is not linearly proportional to the concentration of… CONTINUE READING
