Abstract:
1. A high-speed atomic force microscope comprising: a cantilever having a probe; a piezotube arranged in proximity to the probe; an optical detector configured to detect deflection of the cantilever; a circuit element abutting a first end of the cantilever and configured to exert a force on the cantilever to resist deflection of the cantilever; wherein the circuit element is communicably connected to the optical detector by a first feedback loop; and a feedback controller communicably connected to the piezotube and configured to modulate the piezotube along the Z-axis towards and away from the probe; wherein the feedback controller is communicably connected to the optical detector through a second feedback loop; and a switch communicably connected between the optical detector and the first and second feedback loops.
