Fig.3From: Flexible minimally invasive coherent anti-Stokes Raman spectroscopy (CARS) measurement method with tapered optical fiber probe for single-cell applicationThe FWM signals of MMF cover from ~ 2700 cm−1 to 2900 cm−1 and interfere with the detection of C–H bond vibrations. The FWM signals of FMF cover from ~ 3400 cm−1 to 3800 cm−1 and avoid interference to the detection of C–H bond vibrationsBack to article page
