Abstract

In second-harmonic scanning imaging of interface structures, interference from constant-background contributions can lead to severe distortions of the second-harmonic image compared with the true interface morphology. Similar phenomena can appear in time-dependent second-harmonic measurements. We present an analysis of these effects and demonstrate a simple but powerful technique to eliminate these coherence artifacts.
