Fig. 8From: Optical excitation of atomic force microscopy cantilever for accurate spectroscopic measurementsTop shows the theoretical Acirc′ and the sensitivity S for a set of interference fringes. Bottom shows the theoretical and experimentally measured oscillation amplitude of the cantilever as a function of phase delay (cavity length). The theoretical amplitude was calculated by multiplying circulating enhancement factor Acirc′ by sensitivity SBack to article page
