ABSTRACT:
The present invention provides apparatuses and methods for determining spatial information of a workpiece surface positioned in a predetermined coordinate system. Apparatuses and methods of the present invention can be used to determine one or more coordinates of one or more measurement locations of a workpiece within a predetermined coordinate system. Such coordinates can be used to define points, lines, and/or surfaces of the workpiece within the coordinate system. In one exemplary application, apparatuses and methods of the present invention can be used to determine spatial information of surfaces of head suspensions or head suspension assemblies such as those that are generally utilized in dynamic storage devices such as magnetic disk drives. Such spatial information can be used to determine z-height and/or static attitude, for example.
