Assignee: BRUKER NANO, INC.
Field: Measurement (Instruments)
Classification: CPC G  B | IPC B  G

Claim 16:
17. A method according to claim 9, further comprising:
during a first period of time acquiring, from a sensor of the electronic circuitry of the apparatus, a first set of electrical signals at a frequency from said set of frequencies to determine a depth of deformation of the surface with the tip of the probe, and
during a second period of time acquiring, from the sensor of the electronic circuitry of the apparatus, a second set of electrical signals at a reference frequency to compensate for the change in the area of contact caused by the creep of the surface of the viscoelastic sample,
wherein the sensor includes at least one of a deflection sensor and a sensor configured to measure a position of the cantilevered probe with respect to the surface of the viscoelastic sample.
