Which visual outcome is caused within retinal imaging due to decreased temporal coherence of light?

A)Speckle pattern contrast decreases
B)Achromatic aberration becomes dominant
C)Chromatic dispersion sharply increases
D)Overall image brightness intensifies

💡 Explanation

Decreased temporal coherence means broadened non-monochromatic light is used, resulting in speckle pattern reduction because constructive/destructive interference reduces, whereas a more coherent source yields a sharper speckle pattern; therefore, speckle contrast decreases rather than intensifies or causing aberrations.
