NDI or Northern Digital Inc. produces advanced metrology solutions for inspection, reverse engineering and high-speed part tracking based on an all-in-one tracker, which is beamless and armless for easy portability, setup and use, even in congested areas. With the ability to track, measure, and scan, the requirement for multiple single technology systems is potentially eliminated. An advanced Dynamic Referencing feature adds higher shop-floor accuracy, while a wireless design urther enhances usability and operator freedom.
The OPTOTRAK PROseries Optical Trackers is the centrepiece of NDI's metrology offerings offering high accuracy, high performance and ease of use, in three different measuring volumes. It is positioned as a portable CMM offering fast and easy measurements.
A Dynamic Measuring option with OPTOTRAK captures up to 4,500 measurements per second of fast, complex motion of multiple objects (up to 512 targets) over large volumes with exceptional precision - facilitates advanced motion analysis of 3D and 6DOF measurements changes over time, dynamic motion measurement of vibrations, travelled paths, velocities, accelerations, displacements, positions, orientations, deformations, and angles – allowing the dynamic behaviour of parts, structures and assemblies to be measured and studied.
A handheld touch-probe option with OPTOTRAK allows good access to features over large areas for quick shop-floor computer-aided inspections with real-time part-to-CAD comparisons.
The ScanTRAK TM laser scanner option allows efficient large volume high density point-cloud inspections and reverse engineering or modelling on the shop-floor.
NDI also offers an entry-level VicraSCAN TM solution using unique self-positioning technology, ideal for creating 3D models for design, archival and advanced visualization.
