← ScienceFor LiDAR rangefinders, which risk increases when atmospheric particulates depolarize returning beams?
A)False target reflections increase sharply✓
B)Laser power fluctuates irregularly
C)Receiver aperture angle decreases severely
D)Sampling ADC bit-depth collapses randomly
💡 Explanation
Signal depolarization reduces the ability to filter signal returns, because polarization maintains signal integrity; therefore, false positives increase rather than other noise factors which are mitigated with thresholding alone.
