  • New Precise Method for Measuring Strip Thickness Using Laser Profile Scanners
    is their thickness profile. Deviations occur mainly at the start of the processing chain in hot or cold rolling processes. In order to ensure that the nominal thickness is maintained, it is necessary to determine the instantaneous value of the control variable dynamically and precisely. This requires
  • Precise 2D/3D Measurement Using Laser Profile Scanners
    The principle of triangulation - the geometric measurement using three-point relationships - has been known for many centuries. In the 18th century, this land survey method established itself in Europe. However, the procedure can also be applied on a significantly smaller scale. Using laser line
  • Basic Principles of Laser Scanning Microscopes
    microscope is gathering attention as the device of choice for easy three-dimensional surface profile measuring in air, without touching the sample. Covered within are the basic principles of and the features and applications of Olympus industrial laser scanning microscopes, with primary focus
  • Geometric Profile Thickness Measurement with Integrated Temperature Compensation Allows Reliable Monitoring of Maximum Tolerances
    to the extrusion width and profiling, traversing measuring techniques with high lateral resolution are best suited to monitor the manufacturing process and in the ideal case to regulate with a direct coupling. High lateral resolution is very efficiently achieved with optical measuring techniques such as laser
  • Novel High-Brightness Fiber Coupled Diode Laser Device
    unlimited flexibility. In addition to the transport function the fiber serves as homogenizer: the beam profile of the laser radiation emitted from a fiber is symmetrical with highly repeatable beam quality and pointing stability.
  • CMOS Cameras of Photonfocus for 3D Laser Measuring Technology (.pdf)
    Important parameters for trouble-free rail traffic are the rail profile, the position of the rail, the track gauge, wear of the rail bodies and the sinking of the track bed. The 3D laser measuring technology presented here is based on the principle of laser light section procedure and can be used
  • Laser sensors to guide VW Passat in next Darpa Challenge
    and its reflection being received determines the distance to the object. A rotating mirror lets the laser range finder operate as a scanner, with the mirror deflecting each outgoing beam. This lets the system build a profile of the environment within the laser scanner's range. The car, fielded by a group
  • 10kW Direct Diode Laser System with Homogized 55 x 20mm² Top-Hat Intensity Distribution
    the intensity distribution of the laser beam is homogenized in both axes leading to a 55 x 20 mm² Top-Hat intensity profile at a working distance of 400 mm. Homogeneity of the intensity distribution is better than 90%. The intensity in the focal plane is 1 kW/cm².
