Abstract
A probe tip locator for use in determining the x-axis location and y-axis location of a probe tip of a microscope relative to the locator, the locator comprising a plurality of first reference lines parallel in a first direction, each of the first reference lines representing a predetermined x-axis location of the probe tip; a plurality of sets of parallel encoded bit fields, each one of the sets corresponding to one of the first reference lines; and a plurality of second reference lines parallel in a second direction, each one of the second reference lines intersecting at least one of the first reference lines at an acute angle, such that a scan of a portion of the locator is used to determine the x-axis location and y-axis location of the probe tip relative to the probe tip locator by movement of the probe tip relative to the probe tip locator.
