← ScienceWhich consequence results when speckle contrast reduction fails while imaging biological tissue microstructure with a laser?
A)Reduced signal-to-noise ratio occurs✓
B)Increased measurement resolution occurs
C)Thermally induced tissue damage occurs
D)Enhanced optical clearing is promoted
💡 Explanation
Speckle contrast reduction failure causes reduced SNR because multiple scattered waves interfere constructively and destructively, producing a grainy pattern which obscures fine details via the Interference mechanism. Therefore, SNR decreases due to signal degradation rather than thermal damage or enhanced clearing processes.
