Abstract: This specification discloses a method and implementations improving the field of holding or mounting Scanning Probe Microscopy probe tips for use and alignment. Specifically, the invention allows probes to be mounted replaceably to a very small SPM actuator and aligned in 5 axis permitting alignment of cantilever to beam and reflected beam to detector. The invention allows for great simplification of SPM design while allowing reduction in sizes and masses of tip mounting apparatus thereby improving performance.

Abstract: 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.

Abstract: 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° to the planar reflecting surface.

Abstract: 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.
