Track & Trace: Marker-free tracing of mass-produced parts.

Production Control

Optical inline measurement technology for 100 percent production control

For production control, Fraunhofer IPM develops optical systems and imaging methods which can be used to analyze surfaces and 3D structures in production and to control processes. The systems measure fast and accurately so that small defects or impurities can be detected, even at high production speeds. This means that 100 percent production control in real-time is possible against the backdrop of the fourth industrial revolution.

A wide range of methods is used, including digital holography, infrared reflection spectroscopy and fluorescence methods, combined with fast, low-level image and data processing. The systems are used in applications such as forming technology in the automotive industry and for quality control in medical products.

Our 2D and 3D inline measuring systems supply high precision measurements in real-time and under hardest production conditions, for example for controlling sensitive production processes. This is achieved by a combination of optical measuring techniques with extremely fast data processing.  Our turnkey systems for surface analysis use fluorescence measurement techniques as well as infrared reflection spectroscopy and laser-induced breakdown spectroscopy. In systems engineering Fraunhofer IPM relies on its long-standing experience in optical units, image recording and image processing.

We offer the following services relating to all aspects of production inspection

  • Prototyping and development of customized complete solutions
  • Commissioning and maintenance of the inline systems on-site
  • Technology transfer and training
  • Consultancy for and assessment of technology
  • Feasibility studies and suitability tests
  • Contract measurements and measurements at customers' premises
  • Workshops

Digital holography in production - survey article in LAM

Researchers from Fraunhofer IPM provide an overview on the range of industrial applications of digital holography with multiple wavelengths – from the first installation in the manufacture of sealing surfaces for the automotive sector in 2015 to current use in high-precision processor production.



Press release / Research project GUmProDig starts off / 30.6.2021

Digitalizing processes for more energy-efficient production

As part of the GUmProDig research project, Fraunhofer IPM and its partners are developing a free-fall quality control and component tracing system for formed light metal parts, which is intended to enhance energy-efficient production.


Press release / Project DiGeBaST / 5.5.2021

Marker-free identification of logs

Fraunhofer IPM and its partners are developing a mark-free procedure for identifying logs and trunk sections. The aim of the DiGeBaSt project, which launched in April, is to be able to trace individual logs from when they are felled in the forest to when they are scanned in the sawmill. Unique structures on sawn surfaces are used to identify each log.
