Which limitation occurs when using a low-coherence light source for optical coherence tomography?

💡 Explanation

Lower coherence reduces image resolution because the interference signal decreases rapidly with depth, shortening the coherence length. Therefore, axial resolution is limited, rather than diffraction increases which relate to aperture or chromatic aberration correction which address frequency spread.
