afc Detector SAL3D Tools The AQSENSE SAL3D Peak Detector Tool provides unparalleled laser stripe dtection for triangulation applications. With this new detection technique, height variations as small as 5 microns can be detected with 90 degrees between camera and laser, with a Field of View of 130mm. O Peak Detector X COG Features: /s / \  Up to 1/64th of a pixel detection 镕 Local maximum intensity detection  Reliable with a wide range of surface materials Օ Very smooth acquisition directly from the detector Speed Tests ROI size (pixels) max.
