Your solution for vertical measuring is the Laseruler which is laser-interferometer
This laser-based universal length measuring system (ULM) has been developed by Pratt & Whitney for gage calibration laboratories that need to precisely measure length, outside diameter, inside diameter, pitch diameter, lead, major/minor diameter, taper, linear displacement, and thickness.

Ball measurement presents challenges not found in parallel surface and cylindrical geometries. One of the approaches presented, was developed to optimize the balance between speed and accuracy typically associated with selection of measurement methodology. A brief discussion of the measuring instrument used is also presented. Read more...More Product Announcements from Pratt & Whitney Measurement Systems, Inc.
High accuracy is maintained by its laser interferometer, zero Abbe offset design, and large measuring table (100 lb [45 kg] capacity) with center position, height, pitch, and yaw controls. The computer-controlled precision air bearing slide and gaging probes remove operator-influenced errors commonly observed with traditional gaging methods by maintaining constant force Read more...More Product Announcements from Pratt & Whitney Measurement Systems, Inc.
