Smart Line Scan Measurement Systems

Current industrial machine vision applications mostly rely on PC‐based image processing. Smart camera systems, which incorporate an image sensor and computing capabilities, were initially restricted to very simple tasks like barcode reading and interpretation. But as the computing capabilities of embedded systems increased, smart cameras are now able to handle a wide range of applications.

Stereo Applications Need a Dedicated Lens Choosing

Stereo cameras perceive the world in a manner similar to humans; this similarity allows machines using stereo technology to perform and interact like human partners. Robots equipped with a stereo camera can grasp objects autonomously, without the need for additional sensors or lights. Autonomous cars can have the ability to detect a human crossing the street and accurately determine their distance from the moving car, and…

Monitoring Tasks in 3D Printing

3D printing is currently experiencing a genuine boom. Whereas 3D printers were originally intended only for the production of prototypes and for the production of individual parts, they have since been used for series production, too. To create high quality products, precise guidance of the print head, and accurate positioning are required. Reliable real‐time control is, e.g., provided by the high precision optoNCDT 1420…

Beam Shaping

Using Diffractive Optical Elements

A diffractive optical element (DOE) uses thin micro‐structure patterns to alter the phase of the light that is propagated through it. Those micro‐structures, once properly designed, can manipulate the light to almost any desired intensity profile or shape. This technology enables many functions and light manipulations which are not feasible with standard refractive optics.
