We demonstrate a system for the phase-resolved epi-detection of coherent anti-Stokes Raman scattering (CARS)signals in highly scattering and/or thick samples. With this setup, we measure the complex vibrational responses of multiple components in a thick, highly-scattering pharmaceutical tablet in real time and verify that the epi- and forward-detected information are in very good agreement. © 2014 Optical Society of America
