← ScienceWhich outcome reduces the accuracy of LIDAR systems?
A)Atmospheric turbulence causes beam decoherence✓
B)Increased humidity creates Fresnel diffraction
C)Rayleigh scattering reduces signal intensity
D)Thermal blooming diminishes laser wavelength
💡 Explanation
Atmospheric turbulence introduces variations in the refractive index, causing beam decoherence. This leads to phase differences across the beam. Therefore, wavefront distortion occurs rather than accurate distance measurement because of beam steering from refraction.
