← ScienceWhich phenomenon compromises data recovery in holographic storage when media degrades?
A)Speckle noise obscures bit patterns✓
B)Chromatic dispersion blurs fringe visibility
C)Material fatigue raises recording threshold
D)Increased volume reduces diffraction angle
💡 Explanation
Speckle noise obscures bit patterns because random nanoscale variations within the degrading holographic media introduce variations in the optical path length, causing destructive interference. Therefore, data recovery is compromised, rather than by dispersion, fatigue, or volume reduction.
