Cross Scanner For Optical Feature Measurement
Cross Scanner from Metris is a patented high-speed, multi-stripe laser sensor targeting the inspection of features and gap and step in automotive applications.
CMM-based feature inspection, reverse engineering
Metris has launched the XC50-LS cross scanner with long stand-off distance for CMM-based feature inspection and reverse engineering applications at Control 2006.
Traditionally such features are inspected using tactile probes mounted on Coordinate Measuring Machines.
The Cross Scanner complements the tactile probing methodology with a high speed non-contact approach for feature measurement.
Metris already offers a single stripe solution oriented towards digitizing and full part inspection.

As such the multi-stripe laser sensor completes Metris' unrivalled range of integrated solutions for all aspects of laser scanning.
Changing the way feature scanning is done - Laser scanners have already proven their uses and benefits in areas of quality control such as first article inspection, off-line inspection and troubleshooting.
Compared to traditional touch probe testing, laser scanning enables fast acquisition of accurate 3D pointcloud models that can be subsequently used for full part inspection or reverse engineering applications.
However fast and accurate inspection of features such as holes, slots, gap and step remains to be an inspection challenge.
The Cross Scanner introduces a patented technical paradigm that measures holes and features in one fast single scan by combining 3 laser stripe scanners whose planes are rotated by 120 degrees and slightly tilted.
The single laser stripe scanning method measures the intersection of a laser plane with an object from a single view direction.
This approach cannot capture information outside areas that are not viewable by both the laser plane and the viewing direction.
This characteristic of single laser stripe scanners requires that multiple scans are taken from different directions.
Objects having several features require at least three scans to obtain a sufficiently detailed digitized surface.
The patented cross sensor, also denoted as the XC, introduces a number of advantages that represent a breakthrough for laser digitizing.
A higher speed and increased flexibility is obtained for real 3D measurement by avoiding the use of a motorized sixth axis (C axis).
Compared to a traditional laser scanner mounted on a Renishaw PH10, the cross sensor has an even higher speed and flexibility, avoiding the discrete repositioning of the sensor head.
Another important advantage is the better resolution of the XC scanner since the object is digitized with an optimal density in all directions.
The most important benefit is achieved by having a real 3D measurement resulting in an accurate representation of the measured feature.
Typical applications In order to provide a complete quality control solution for its customers Metris continuously develops and manufactures both laser scanner hardware as well as a comprehensive set of application software tools.
With the introduction of the Cross Scanner, Metris is yet again opening up new opportunities for customers that wish to improve their quality processes. Request a free brochure from Metris ...
While the cross scanning technology applies to general digitizing applications, it is particularly suited for sheet metal quality control containing features Metris' laser scanning market leadership is consolidated in alliances with major CMM partners such as Mitutoyo, Brown and Sharpe, DEA, LK, Wenzel, etc.
