  • Inverse Fringe Projection System

    3D measuring system based on fringe projection developed and set up at IMR. The system consists of a projector (ACER P7500) and an industrial camera (AVT Pike 505B) and is completely freely programmable with Python and C / C ++.

    Algorithms for inverse fringe projection are implemented and researched within the framework of the SFB 871 (subproject C2).

     

    • Camera: AVT Pike 505B (5 MPixel)
    • Projector: Acer P7500 (4000 ANSI Lumen)
    • Conventional and inverse fringe projection
  • Characterization of Micro-structured Surfaces

    A measurement setup for characterizing microstructured surfaces is being developed at the IMR. The measuring system can be used to find microscopic defects on large surfaces. In addition, the geometrical detection of the surface structure is possible.

    Main Components: 

    • Different cameras: high speed and high resolution
    • Highly magnifying, telecentric lenses
    • Positioning unit with 3 axes
    • LED and laser lighting

    Research:

    • Geometric recording of micro-structured surfaces
    • Search and identification of microscopic defects on large surfaces
    • Microscopic surface examinations under rough, industrial conditions.
  • Laboratory Operating Room

    The laboratory operating room is equipped with components for patient positioning, care and lighting. The TruSystem 7500, iLED and TruPort systems from TRUMPF Medizin Systeme are used here. This means that a large number of surgical procedures and situations in a conventional operating room can be simulated.
