← ScienceWhich limitation arises when holographic data storage density plateaus?
A)Beam divergence reduces data separation✓
B)Non-linear effects hinder readout
C)Material fatigue increases bit errors
D)Decreased refractive index blurs data
💡 Explanation
Beam divergence increases with greater hologram density because diffraction broadens the focused spots. Therefore, data separation suffers, rather than the other effects, since diffraction is directly coherence dependent.
