  • Patent number: 11320454
    Abstract: The present document relates to a scanning probe microscopy system and method for mapping nanostructures on the surface of a sample. The system comprises a sample support structure, a scan head including a probe comprising a cantilever and a probe tip, and an actuator for scanning the probe tip relative to the sample surface. The system also includes an optical source, and a sensor unit for obtaining a sensor signal indicative of a position of the probe tip. The sensor unit includes a partially reflecting element for reflecting a reference fraction and for transmitting a sensing fraction of the optical signal. It further includes directional optics for directing the sensing fraction as an optical beam towards the probe tip, and for receiving a reflected fraction thereof to provide a sensed signal. Moreover the sensor includes an interferometer for providing one or more output signals, and signal conveyance optics for conveying the sensed signal and the reference signal to the interferometer.

  • Patent number: 9766266
    Abstract: The invention is directed at a method of advancing a probe tip of a probe of a scanning microscopy device towards a sample surface. The scanning microscopy device comprises the probe for scanning the sample surface for mapping nanostructures on the sample surface. The probe tip of the probe is mounted on a cantilever arranged for bringing the probe tip in contact with the sample surface. The method comprises controlling, by a controller, an actuator system of the device for moving the probe to the sample surface, and receiving, by the controller, a sensor signal indicative of at least one operational parameter of the probe for providing feedback to perform said controlling.
