← ScienceWhich outcome occurs to sensor resolution when using laser Doppler velocimetry?
A)Increased visibility of fluid boundaries
B)Reduced signal to noise ratio
C)Enhanced spatial measurement resolution✓
D)Diminished data transmission bandwidth
💡 Explanation
Enhanced spatial resolution results from laser coherence because constructive interference sharpens the Doppler signal, pinpointing velocity accurately, therefore resolution increases rather than a noisier signal or limited bandwidth which is a separate factor.
