IDS Camera Automates Inspection

Until now, machine-based surface inspection methods have checked visual quality by means of direct or transmitted light in conjunction with a camera system. When it comes to the automated inspection of reflective and smooth surfaces, however, these methods involve problems. The resulting reflections need to be either eliminated or included in the measuring process. Consequently, complex lighting conditions using polarized light or fringed projection in a darkroom are required, or the objects need to be positioned with high precision and completely shock-free. Whichever solution is employed, neither permits an automated 100% in-process inspection.
