← ScienceWhich consequence results when coherence is lost during Optical Coherence Tomography (OCT)?
A)Reduced axial resolution in the image✓
B)Increased penetration depth in the tissue
C)Enhanced signal to noise ratio
D)Spectrometer exceeds saturation limit
💡 Explanation
Loss of coherence reduces visibility of interference fringes, because the interference of the reference and sample beams no longer constructively add to produce a strong, measurable signal enabling high resolution; therefore, axial resolution suffers rather than improve penetration or signal enhancement.
