← ScienceWhich effect impairs LIDAR image resolution because of atmospheric effects?
A)Atmospheric coherence length reduction✓
B)Increased Rayleigh scattering intensity
C)Doppler shift induced broadening
D)Reduced laser pulse peak power
💡 Explanation
Atmospheric turbulence reduces coherence length via random variations in refractive index, resulting in wavefront distortions and degraded LIDAR resolution; therefore the correct answer is coherence length reduction, rather than scattering alone which is distinct even with coherent beams.
