Which outcome reduces data readout accuracy when using a Coherent anti-Stokes Raman Scattering (CARS) microscope?

A)Non-resonant background intensity interfering strongly
B)Increased photobleaching of the sample volume
C)Lower signal strength at high frequencies
D)Thermal lensing causing image distortion

💡 Explanation

A strong non-resonant background signal occurs because of electronic hyperpolarizability, leading to constructive interference of the signals, rather than destructive interference. Therefore, the CARS signal is contaminated, rather than providing a high signal-to-noise readout.
