Which imaging consequence appears when coherence length drops prematurely?

💡 Explanation

Excessive surface roughness causes the emitted beam to lose coherence via increased path length differences; therefore speckle artifacts start dominating, rather than resulting in a clearer imaging picture because chromatic aberration is not influenced by coherence in this case.
