Capture the fast, complex motion of multiple objects over large volumes with exceptional precision using NDI’s Dynamic Measuring Machine (DMM). The NDI Dynamic Measuring Machine is one of the most powerful and capable tools for dynamic measurement and advanced motion analysis.

The DMM uses an Optical Tracker to track specially designed targets that mark specific points of interest. The Optical Tracker’s most powerful feature is the unique ability to track how 3D and 6DOF measurements change over time, adding a new dimension to industrial metrology by allowing for motion tracking and dynamic measurement.

Tracking System

DMM adds dynamic motion measurement capabilities to the base PRO CMM system, combining best-in-class 3D and 6DOF dynamic tracking and portable optical coordinate measurement, for advanced real-time metrology and motion analysis.



Improve your shop-floor metrology results with this portable optical tracker that provides the highest accuracy and largest measurement volume of any system in its class. Learn more.




The PRO CMM with DMM includes software to analyze 3DOF motion or 6DOF position of objects. By providing instant visual feedback and live data export, NDI’s DMM software allow users to easily track dynamic motion measurements such as displacement, acceleration, deformation, and frequency response.

NDI can also solve your unique measurement problems with custom DMM software.




The exceptional range and resolution of the PRO CMM with DMM allows for precise, dynamic motion tracking within many industries and applications, including:

  • Boat Tank Tracking
  • Wind Tunnel Tests
  • Tow Tank Testing
  • Airfoil Deflection
