← ScienceWhich consequence results when a laser in a LiDAR system encounters heavy rain?
A)Reduced range and data accuracy✓
B)Increased signal-to-noise improved ranging
C)Spurious resonant backscattering amplification error
D)Beam self-focusing causing phantom detection
💡 Explanation
Range and accuracy decrease because Mie scattering dominates by large water droplets, strongly scattering the laser beam. This decreases the signal's coherence back to the sensor, therefore usable range suffers rather than improving in adverse conditions.
