Phase Vision - Innovation 3D Measurement Solutions

How the Phase Vision Quartz Scanner works

The Phase Vision Quartz Scanner uses SmartFringe technology, a patented system based on structured white light, to measure 3D objects both accurately and quickly. The Quartz Scanner consists of two main elements - a high specification projector and an industrial digital camera, both of which are controlled by Phase Vision's Gem Studio software.

Sequential patterns of dark & light fringes are projected from the Quartz Scanner onto the component surface. The fringe pattern is generated in the form of sine waves, the amplitude of which are in the direction of the projector beam - the orientation of this sine wave and the gradual transition between dark and light at the edges of each fringe are key features of Phase Vision's patented technology. The patterns generated by the fringes on the component surface are captured by the Quartz Scanner's camera.

In order to generate a full surface map, or point cloud, multiple scans are taken of the component from different directions. To acquire multiple scans, most components can be indexed on a rotary table fixture - optical reference points on the table allow individual scans to be joined together to form the full component measurement. For larger parts (eg aircraft structures), the scanner can be repositioned for each scan, or multiple scanners can be used to acquire the complete data set.

Phase Vision's Gem Studio software then models the shape of the component surface from the scan data, which is displayed on-screen in the form of a point cloud. This data can then be exported in a range of widely used file formats for analysis, e.g. comparison to CAD data or Reverse Engineering.
