Optical-force-induced artifacts in scanning probe microscopy

Dana C. Kohlgraf-Owens, Sergey Sukhov, and Aristide Dogariu

In the practice of near-field scanning probe microscopy, it is typically assumed that the distance regulation is independent of the optical signal. However, we demonstrate that these two signals are entangled due to the inherent action of optically induced force. This coupling leads to artifacts in both estimating the magnitude of optical fields and recording topographic maps.
