Which risk increases when optical coherence tomography resolution is at limit?

A)Speckle noise obscures small features
B)Chromatic aberration blurs deep images
C)Spherical artifacts generate false echoes
D)Stimulated emission floods real signal

💡 Explanation

When resolution is maximized, speckle noise becomes dominant because optical interference from unresolved structures increases the signal variation therefore obscuring the true microscopic features rather than chromatic or other aberations.
