The Polaris Vega® optical measurement solution provides real-time 3D position tracking of markers attached to tools. Using near-infrared (IR) light to track passive or active wireless markers, the Polaris Vega can track multiple wireless tools at once within a large pre-calibrated measurement volume. Measurement data are captured with sub-millimetre accuracy and repeatability for integration into OEM customers’ most challenging—and groundbreaking—tool navigation and visualization applications.
The Polaris Vega® is an optical measurement solution that uses near-infrared (IR) light to calculate the 3D positions of markers attached to tools.
For passive optical tracking, the Polaris Vega unit floods the measurement volume with IR light emitted from its illuminators. This light is reflected back to the IR sensors by retro-reflective markers attached to tools.
In active wireless tracking, the illuminators emit high frequency ‘chirps’ that activate IRED markers on the active wireless tools; i.e. the IRED markers emit their own light rather than reflect it.
The reflected or emitted light is detected by the IR sensors, which determine the markers’ 3D coordinates via triangulation. Coordinate data are mapped to the associated tool and used to calculate the tool’s position and orientation. These data are communicated to the host OEM application for integration into tool navigation and visualization workflows.
Measurement accuracy and reliability are the cornerstones of all NDI solutions, which are evident throughout the design, manufacture, and integration of the Polaris Vega.
The Polaris Vega enables OEM customers to integrate optical measurement technology into the most complex tool navigation applications. Here are some examples of how our customers have customized and incorporated 3D measurement data into their system workflow:

NDI tracking and measurement products (listed below) are general metrology components that can be integrated into customer products, research experiments, and/or as components of medical devices that require precision measurement and tracking. While NDI components and technology can be integrated into original equipment manufacturer (OEM) medical devices, they are not specifically intended for a given application and, as such, have not been developed or manufactured in accordance with medical device standards. It remains the responsibility of the OEM customer or end-user to determine and test the suitability of NDI components and technology for their intended use, including performing any required ethics approval, verification, and validation required to demonstrate suitability and compliance. System-level testing, certification, and validation are the responsibility of the original equipment manufacturer or the applicable end-user and should be completed prior to use of NDI products or technologies in any application.
