Teledyne DALSA's Z-Trak 3D laser profiler series delivers high resolution height measurements using laser triangulation techniques. These compact units feature powerful FIR-peak detector and are factory calibrated for rapid field deployment. With a wide selection of models, Z-Trak is able to measure 10 to 1000 mm Z-axis range with resolutions down to 5µm. Z-Trak delivers highly linear and repeatable results by combining reflectance based dynamic laser power control and Scheimpflug optimized optical path. With sophisticated algorithms and blue laser options for highly reflective surfaces, or red laser options for more complex surfaces, Z-Trak proficiently handles virtually any 3D inspection task. Support for GigEVision standard allows Z-Trak series 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.
There are a number of techniques available for 3D imaging. The Z-Trak series of 3D laser profilers uses a laser triangulation technique to deliver high resolution height measurements.
Z-Trak emits a laser onto an object of interest; the reflection's position in the sensor's field of view allows the scanner to triangulate the point in space at which the laser hits the object.
The diagram below illustrates the terms used to specify Z-Trak's performance.
