← ScienceWhich consequence results when path length mismatches in optical coherence tomography?
A)Image artifact generation and blurring✓
B)Increased signal-to-noise ratio linearly
C)Accurate refractive index measurement
D)Higher degree of light absorption
💡 Explanation
Path length mismatches degrade coherence, resulting in image artifacts and blurring of tissue structures because *optical interference* is diminished; therefore, resolution is decreased, rather than increased signal, because the matched path lengths correlate to constructive interference areas.
