Teledyne DALSA Z-Trak 3D Laser Profiler

Teledyne Dalsa Ztrak 3D laser profiler - all models with various configurations shown in the image

Teledyne DALSA's Z-Trak 3D laser profiler series delivers high resolution height measurements in real-time using laser triangulation techniques. These compact units feature powerful FIR-peak detector and are factory calibrated for rapid field deployment. The Z-Trak 3D laser profiler measures 10 to 1000mm Z-axis range with resolutions down to 5µm. Z-Trak produces highly linear and repeatable results by combining reflectance based dynamic laser power control and Scheimpflug optimized optical path. Z-Trak is available in multiple configurations.

All Z-Trak 3D laser profilers are factory calibrated for accurate real-time measurements, and built with IP67 enclosures for harsh envionments. With sophisticated algorithms and blue laser options for highly reflective surfaces, or red laser options for more complex surfaces, Z-Trak laser profilers proficiently handle virtually any 3D inspection task. Support for GigEVision standard enables the Z-Trak 3D laser profilers to work with both the Teledyne DALSA image processing and analysis software packages, as well as a wide variety of third party 3D image processing and analysis packages.

How does 3D imaging work?

As shown in the diagram below, a laser stripe is projected on the object and imaged on an image sensor. The sensor processes the position of the laser stripe to provide lateral and depth information for the X and Z axis data. By moving the object in the Y-Scan direction the Y-axis data point is provided then giving full X, Y & Z dimensional information.
