← ScienceWhich risk increases when optimizing a LIDAR system using low coherence lasers?
A)Speckle noise degrades image quality✓
B)Reduced optical fiber transmission efficiency
C)Increased atmospheric backscatter interference
D)Higher detector array overheating potential
💡 Explanation
Speckle noise increases because lower coherence means more interference variations. Image quality suffers; therefore, speckle noise increases, rather than alternative effects like fiber loss or detector heating, which depend on power, not coherence.
