Which outcome occurs in digital holography when laser speckle reduces coherence?

💡 Explanation

Decreased fringe contrast results from lower coherence speckle because constructive and destructive interference patterns are less defined following the Van Cittert–Zernike theorem; therefore, image quality degrades, rather than increases in resolution or changes in noise, given a constant setup.
