← ScienceWhich effect increases when injected laser coherence exceeds tolerance?
A)Speckle noise within projection surfaces✓
B)Chromatic aberration through optical path
C)Lowered spatial resolution of display
D)Reduced energy efficiency of source
💡 Explanation
Speckle noise increases because constructive and destructive interference patterns arise due to high coherence. Specifically, increased coherence enhances these interferences. Therefore, speckle noise is intensified, rather than chromatic aberration, which relates to wavelength separation.
