A displacement sensor has a graded index multi-mode fiber with a length that is an odd multiple of a quarter pitch length of the graded index multi-mode fiber and a single-mode optical fiber fusion spliced to the first end of said graded index multi-mode fiber. A reflective mirror coating is applied to a planar facet on the second end of said graded index multi-mode fiber. A plurality of mechanical attachments are spaced along the graded index multi-mode fiber and single-mode optical fiber that mechanically deform said graded index multi-mode fiber, when any one of said plurality of mechanical attachments is displaced relative to any other one of said plurality of mechanical attachments.

Fiber optic displacement sensor

Using a local-potential-driving probe drives a conductor to a known potential while adjacent lines are grounded through the sample body reduces electrostatic scanning microscope signal from adjacent lines, allows imaging of metal lines deeper in the sample. Providing different potentials locally on different conductive lines using multiple local-potential-driving probes allows different conductors to be highlighted in the same image, for example, by changing the phase of the signal being applied to the different local-potential-driving probes.

Method for imaging a feature using a scanning probe microscope

A SPM head incorporates a probe and a cantilever on which the probe is mounted. The cantilever has a planar reflecting surface proximate a free end of the cantilever. The cantilever extends from a mechanical mount and a single-mode optical fiber is supported by the mechanical mount to provide a beam. A micromirror is mounted to reflect the beam substantially 90&#xb0; to the planar reflecting surface.

Scanning probe microscope head design

A SPM head incorporates a probe and a cantilever on which the probe is mounted. The cantilever has a planar reflecting surface proximate a free end of the cantilever. The cantilever extends from a mechanical mount and a single-mode optical fiber is supported by the mechanical mount to provide a beam axis at an angle away from normal relative to the reflecting surface.
