Machine Vision Lasers
The combination of laser lighting and machine vision lasers offers interesting possibilities for the automation of visual quality controls. Lasers for image processing are used as a structured lighting in many picture processing systems. With this form of light 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. Depending on the kind of object, that needs to be examined, micro or macro lines or all sorts of patterns (multi-lines, point grids, crosses, circles etc. ) as well as wavelengths (red, green, blue, IR) are used.
