  • Method for controlling a scanning microscope
    Patent number: 9091704
    Abstract: The invention relates to a control method having at least two control loops for a scanning microscope provided with a microlever and an actuator suitable for energizing the microlever, in which a first loop maintains as a controlled variable the oscillation amplitude of the microlever and as a manipulated variable the amplitude of the electric signal supplied to the actuator, and a second loop uses as a controlled variable the amplitude of the aforementioned electric signal and as a manipulated variable the tip-sample distance. Said procedure makes it possible to ignore changes of sign in the tip-sample interaction.
