Figure 5From: A Scheme for Solving the Plane–Plane Challenge in Force Measurements at the NanoscaleScheme of the proposed experimental set-up. A sample is mounted over a three-axis translation system and a two-angle tilt system. The probe, e.g. a cubic like block attached to an AFM cantilever, is measured through a fiber-based interferometer (not shown). The drift affecting the distance between the interacting surfaces is controlled using either electrostatic or optical measurements, as sketched the figureBack to article page
