SAL3D > Peak Detector Tool

The AQSENSE SAL3D Peak Detector Tool provides unparalleled laser stripe detection 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. 

 Features:  Speed Test
  • • Up to 1/64th of a Pixel detection
  • • Local maximum intensity detection
  • • Reliable with a wide range of surface materials
  • • Very smooth acquisition directly from the detector

                    8x to 10x times better detection accuracy

Smoothness Test

  • • 10x smoother than COG-based 3D cameras*
  • • No post-processing required
  • • Smaller defects can be detected
  • • Surface details appear clearly sharp
