← ScienceWhich image blur results when digital holography lacks coherence?
A)Speckle appearance is sharply localized
B)Spatial resolution degrades significantly✓
C)Chromatic aberration effect is amplified
D)Intensity fluctuations remain relatively constant
💡 Explanation
Lower temporal or spatial coherence causes decreased fringe contrast due to broadened interference patterns; therefore spatial resolution in reconstructed images degrades rather than enhanced intensity, sharper speckle, because blurry fringes decrease interference effects.
