← ScienceWhich outcome limits resolution in stimulated emission microscopy?
A)Signal arises from destructive interference✓
B)Luminescence creates secondary scattering
C)Excitation undergoes quantum entanglement
D)Vibrational relaxation diminishes signal intensity
💡 Explanation
Resolution is limited because the *point spread function* broadens due to destructive interference of the emitted photons. This produces artifacts rather than increased resolution; therefore, improving coherence is necessary, rather than other fluorescent effects reducing signal.
