  • Scanning probe in pulsed-force mode, digital and in real time
    Publication number: 20070114406
    Abstract: Microscope, in particular a scanning probe microscope, comprising a programmable logic device
    Type: Application
    Filed: October 23, 2006
    Publication date: May 24, 2007

  • Scanning probe with digitized pulsed-force mode operation and real-time evaluation
    Patent number: 7129486
    Abstract: The invention relates to a method for creating the image of a sample surface to be analyzed, with a resolution which is better than 1 ?m laterally in relation to the sample surface and better than 100 nm vertically in relation to said surface. According to the invention, the surface is scanned on a point-by-point basis by a scanning probe, the distance between the scanning probe and the sample surface at each scanning point being periodically modulated, in such a way that a force-time curve of the probe is produced for this point. The force-time curve is recorded at each scanning point, digitized using an A/D converter, evaluated online in real-time and stored, together with the entire data stream, in a first area of a memory device.
