Which visibility drop occurs when turbulence corrupts interferometry?

A)Speckle contrast decreases noticeably
B)Chromatic aberration exaggerates rapidly
C)Rayleigh scattering intensities increase
D)Fresnel diffraction patterns shift

💡 Explanation

Speckle contrast decreases noticeably because atmospheric turbulence causes constructive and destructive interference patterns (scintillation) to decorrelate during the exposure; therefore, the speckle contrast is lowered, rather than chromatic aberration becoming notable without appropriate materials conditioning.
