← ScienceWhich effect reduces holograms' resolution during reconstruction due to imperfections?
A)Reduced spatial coherence of laser✓
B)Increased sample refractive index
C)Thermal lens induced distortion
D)Polarization state fluctuation
💡 Explanation
Decreased coherence reduces interference patterns during reconstruction because the superposition of imperfectly correlated light produces speckle which blurs fine details. Therefore spatial coherence loss impacts resolution rather than polarization, index changes, and localized thermal gradients alone.
