← ScienceWhich consequence results when the laser current drops within an optical coherence tomography (OCT) device?
A)Increased signal-to-noise ratio reduces image quality
B)Reduced coherence length lowers axial resolution✓
C)Increased pulse duration degrades ranging accuracy
D)Elevated lasing threshold amplifies parasitic oscillations
💡 Explanation
Reduced current shortens, impacting axial resolution of collected data because coherence length is directly proportional to temporal bandwidth. Therefore axial resolution degrades, rather than the other options, because these are more closely coupled with intensity output or electrical rather than optical properties.
