← ScienceWhich consequence results when coherence is insufficient for digital holography?
A)Speckle noise degrades reconstructed images✓
B)Fresnel diffraction patterns become distorted
C)Polarization of light rotates irregularly
D)Chromatic aberration affects blue wavelengths
💡 Explanation
Speckle noise increases when temporal and spatial coherence decline because interference patterns become less stable, therefore sharper images are unobtainable in reconstruction rather than other optical phenomena causing blurring.
