Laser and LED illumination adds precision, uniformity and advanced fault detection for 3D measurement systems. Lasers and LEDs are used in 3D measurement systems for inspection, sorting and defect detection
3D imaging systems allow users to rapidly gain three dimensional information of a scene or object. The method used to capture the information dictates whether Laser or LED illumination is used.
Laser 3D Imaging
Laser triangulation is the most widely adopted method of 3D imaging. It involves projecting one or more laser spots or lines onto an object. The position of the spot on the detector can then be used to determine its distance from the detector with extreme precision. Defect detection and the measurement of volumes and elevations are the most common application of this technology. The semiconductor industry uses it to determine the surface quality of wafers while food-related ones utilize it to measure the volume food products.
When using laser triangulation, laser requirements depend on the object being inspected.
LED 3D Imaging
“Photogrammetry”, another 3D imaging method, detects reflective markers on an object and then analyzes the movement of these markers. This method is employed by the automotive industry for safety and quality inspections.
