Whatever method you're currently using, it's probably not as simple as that which can be performed by a new vision/ultrasonic probe system announced by Mitutoyo America (www.mitutoyo.com). The Ultrasonic Micro and Accurate Probe (UMAP UMAP University Mobility in Asia and the Pacific (Bangkok, Thailand)
UMAP Unidades Militares para Ayuda a la Producción (Spanish: Military Units to Aid Production, Cuba, 1965) 
) uses a vision system to position the probe with an accuracy of 1.4 microns within a measuring range of 12 x 8 x 8 in. The probe, depending on the size system selected (UMAP 130 or UMAP 180), is either 30 [micro]m or 80 [micro]m in diameter. The stylus stylus: see pen.
