Fraunhofer Institute for Physical Measurement Techniques IPM

Measuring | Monitoring | Optimizing

The Fraunhofer Institute for Physical Measurement Techniques IPM develops tailor-made measuring techniques and systems for industry. Many years of experience with optical technologies form the basis for high-tech solutions in the fields of production control, object and shape detection, gas and process technology as well as thermal energy converters.


Business Unit

Production Control

We analyze surfaces and 3D structures of components quickly and with micrometer precision. This means that 100 percent production control in real-time is possible.


Business Unit

Object and
Shape Detection

We detect the three-dimensional shape and position of objects and large structures at high speed and with high precision. Measurements are taken predominantly from moving platforms.


Business Unit

Gas and Process

We develop and manufacture measurement systems for gas and liquid analysis which feature high precision and reliability even under extreme conditions. The scope ranges from laser spectrometers for exhaust gas analysis to energy-efficient gas sensor for  food quality monitoring.


Business Unit

Thermal Energy

We manufacture and optimize materials with special physical properties. These materials form the basis for systems for magnetic cooling or thermoelectric energy harvesting.


Digital holography in motion

In the recently completed “HoloMotion” research project, Fraunhofer IPM has greatly enhanced the established 3D measurement method of digital multiwavelength holography in two directions: On the one hand, components in motion can now be measured with high precision for the first time. Secondly, optical gear measurement using digital holography has been raised to a new level.

50 years of cutting-edge research for greater efficiency and safety

Measurement systems ensure the quality of industrial products, optimize processes and provide safety. Over the past five decades, the Fraunhofer Institute for Physical Measurement Techniques IPM in Freiburg has impressively demonstrated the enormous contribution to efficiency, sustainability and safety that measurement technology can make. This was recognized by representatives from politics and research at an anniversary event. In a panel discussion, the participants discussed how measurement technology can contribute to sustainable and affordable building and housing in the future.

New fabrication technique for periodically-poled lithium niobate

Periodically-poled lithium niobate (PPLN) is a nonlinear-optical crystal with specific photonic properties. It is suitable for example for the frequency conversion of laser light. Researchers at Fraunhofer IPM in collaboration with the University of Freiburg have developed a new technique that allows them to structure PPLN with full flexibility and without masks. They will present the new technique at the LASER World of Photonics trade fair in Munich.

Fuel cell production of the future

Revolutionizing the production of fuel cells – that’s the ambitious goal set by seven partners from research and industry. i-skaB is a joint project for innovative, scalable fuel cell production as well as stack production at 30-second intervals. The project was launched at the beginning of the year and is funded by the Federal Ministry for Digital Affairs and Transport.
