LaserGauge® is not limited to the single laser stripe technology. Other structured light methods are utilized to allow for measurements on different types of components, each with its own advantages.

Single-line Imaging
LaserGauge Technology - Single Laser StripeLaserGauge® predominately uses single-line imaging for surface contour measurement. While not able to provide 3D information of a surface, it is the fastest and most useful of the laser imaging modes.

 

Multiple-line Imaging
Multiple laser line imaging gives much more information of the feature than the typical single laser line imaging. This method yields true 3D information of the surface, although the 3D information is restricted to the laser line locations. App Laser Light Double StripThis method is useful for detection of sensor “pitch” and "yaw" during measurement as well as giving more detailed measurements of the features being scanned. For example, when measuring a radius, it is not necessary for the sensor to be precisely positioned normal to the radius for an accurate measurement. The multiple scans yield the information to accurately calculate the radius at an "off-axis" orientation.

 

Cross-hair Imaging
TApp Laser Light Crosshair Stripehe cross-hair imaging method uses two perpendicular laser stripes to give two independent scans in two planes, giving 3D information of the surface. This method is used for scanning circular features like fasteners, spot welds, etc. to give more information on the feature without taking multiple scans.

 

Leading-edge/Cross-vector Imaging
App Laser Light Wraparound StripeThe leading edge imaging method yields scans on both sides of a part simultaneously. The structured light reflects off one surface, around the edge, then onto the other surface, giving true leading edge scans that can then be processed. The traditional laser triangulation method is unable to do this.

 

Bore Imaging
App Laser Light Circumferential StripeThe last structured light imaging method utilized is the bore inspection method. This allows illumination 360 degrees around the inside of a bore (or other part), and gives radial locations of the surface.
