Abstract
An atomic force microscope is provided having a controller configured to store one or more positional parameters output by a sensor assembly when a light spot is located at a first preset position on the surface of the cantilever. The controller is further configured to operate an actuator assembly so as to induce movement of the spot away from the first preset position, to detect said movement of the first spot based on a change in the one or more positional parameters output by the sensor assembly, and to operate an optical assembly in response to the detected movement of the first spot to return the first spot to the first preset position.
