A Physical Unclonable Function uses random and inherent properties of a physical entity and can be used to uniquely identify components e.g., for anti-counterfeiting purposes. In this work we demonstrate that the surface patterns of injection moulded

Individual traceability of components enables efficient quality control, improving operational efficiency, or smart manufacturing approaches like big data analysis as well as customized mass production. Conventional track and trace solutions however,

In emitter wrap through (EWT) solar cells, laser drilling is used to increase the light sensitive area by removing emitter contacts from the front side of the cell. For a cell area of 156 x 156 mm 2 , about 24000 via-holes with a diameter of 60 μm h

Three-Dimensional Image Capture and Applications
The acquirement of 3D-information is currently achieved by stereophotography, line and grid projection techniques or bylaser scanning in combination with a fast distance measuring device.This paper describes a new principle using a single CCD-camera

Three dimensional inspection techniques for industrial applications are normally based on either photogrammetric, triangulation or time-of-flight techniques. Combining the latter with an optical demodulation method offers the possibility to obtain 2D

CNN based cameras are able to process images in the kHz range in machine vision systems, as demonstrated for the closed loop control of laser welding processes. Other applications do not benefit from a comparable light source. This paper reports the
