Abstract

A micrometer head displacement system includes a micrometer head and an imaging portion. The micrometer head includes a coarse scale and a fine scale. The system is configured to: acquire at least one image of the micrometer head from the imaging portion; determine a coarse measurement based at least in part on the at least one image wherein the coarse measurement corresponds to a coarse relative position between the coarse scale and a coarse fiducial line; determine a fine measurement based at least in part on the at least one image and based on calculating an interpolated position of the a fiducial line wherein the fine measurement corresponds to a fine relative position between the fine scale and the fine fiducial line; and determine a micrometer head displacement based at least in part on summing the coarse measurement with the fine measurement.
