← ScienceWhich risk escalates when laser coherence exceeds detector resolution?
A)Speckle interference causes image artifacts✓
B)Chromatic aberration distorts fringe visibility
C)Stimulated emission overcomes detector saturation
D)Increased thermal noise obscures signal
💡 Explanation
Speckle interference creates grainy patterns because coherent light is scattered, resulting in constructive and destructive interference. Therefore, artifacts occur rather than chromatic aberration, which is wavelength-dependent, or thermal noise, which lacks spatial coherence.
