Machine vision lasers

The combination of laser lightings and machine vision lasers offers interesting possibilities for the automation of visual quality controls. Lasers for the image processing are used as a structured lighting in many picture processing systems. With this form of lights the spatial contours of moving and motionless objects can be included. The lasers are used in machine vision measurement to recognize defects, presence, diameters, edges, cracks and to align them in the following step. Depending on the kind of object, that needs to be examined, micro or macro lines or all sorts of pattern (multi-lines, point grids, crosses, circles etc. ) as well as wavelengths (red, green, blue, IR) are used.
