Which effect degrades sensor resolution in LIDAR systems?

A)Speckle noise from laser incoherence
B)Chromatic aberration from LED divergence
C)Spherical aberration from lens imperfections
D)Thermal blooming from high-power usage

💡 Explanation

Speckle noise arises because interference patterns from reflections of a partially coherent laser beam cause random intensity fluctuations, therefore reducing image clarity, rather than being caused by chromatic aberration which is specific LED divergence.
