Abstract
A topography sensor and method include a probe configured to traverse a surface to determine a topography. A stray magnetic field is disposed in proximity to the probe. A magneto-resistive sensor is configured so that the stray magnetic field passing through it changes in accordance with positional changes of the probe as the probe tip traverses the surface.
