Which resolution limit occurs when imaging through fog?

A)Speckle visibility severely degrades coherence
B)Scattering increases path length variation
C)Absorption reduces signal intensity
D)Dispersion broadens the pulse width

💡 Explanation

Resolution degrades because **speckle** relys on **optical coherence**. When light scatters off of fog particles, **interference** creates a speckle pattern with very low visibility; therefore speckle imaging is ineffective with increased incoherence, rather than scattering, which affects intensity unevenly or pulse dispersion, which affects pulses.
