← ScienceWhich outcome disables LIDAR phase detection accuracy when operating?
A)Atmospheric index-of-refraction turbulence scrambles coherence✓
B)Reduced laser modulation at high speed
C)Increased pulse width broadens spectra
D)Lens aberration lowers planar wavefront quality
💡 Explanation
Scrambled phase detection results from atmospheric disturbance because the changing refractive index introduces path length variations exceeding the source's coherence length. This is atmospheric turbulence, therefore coherence is broken, rather than issues stemming from modulation or optics.
