← ScienceWhich outcome results when an inadequate settling time exists in digital holographic interferometry?
A)Reduced fringe visibility appears✓
B)Increased diffraction causes distortions
C)Polarization shifts induce artifacts
D)Laser speckle contrast strengthens
💡 Explanation
Reduced fringe visibility occurs because errors propagate through digital reconstruction during temporal phase shifting. Inadequate settling after changes during time frame sampling interferes constructively with earlier signals, therefore overall fringe reduces rather than amplifying others given the constraints, because intensity changes shift over time.
