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.


A new precision method – fluorescence measurement technology for quality assurance in production

Fluorescence measurement technology has so far been used almost exclusively for qualitative analyses. Now, for the first time, a team of researchers at Fraunhofer IPM is successfully using the method to obtain quantitative measurements with a high local resolution, and is receiving the Joseph von Fraunhofer Prize in recognition of this achievement.

F-Scanner enables optimized aluminum stamping

In car body manufacturing, it is far more difficult to process aluminum blanks than their steel counterparts. One key parameter determining the quality of metal forming is the thickness of the lubrication layer on the blank surface. The F-Scanner fluorescence measurement system is the only device capable of performing spatially resolved measurements of this layer thickness during production. Four F-Scanners have now been delivered to a US automobile manufacturer where they will be used to ensure the quality of car body parts.

High-precision 3D surveying of the Liebensteinspeicher reservoir

Dams are amongst the most closely monitored structures in Germany. However, traditional methods for surveying the basin of a reservoir are very time-consuming and produce comparatively imprecise data. On behalf of the Weiden Water Management Authority, GeoGroup GmbH and Fraunhofer IPM have now conducted a survey of 100 percent of the Liebensteinspeicher reservoir in Germany’s Upper Palatinate region. The resulting high-precision 3D data provides insights into the reservoir volume, the water table area and the depth of the lake.

Quantum imaging: Pushing the boundaries of optics

Quantum mechanically entangled light particles break down the boundaries of conventional optics and allow a glimpse into previously invisible wavelength ranges, thus bringing about new possibilities for imaging techniques, microscopy and spectroscopy. Unearthing these possibilities and creating technological solutions was the goal of the Fraunhofer lighthouse project QUILT. Fraunhofer IPM contributed to the success of the project by a world first, the »Quantum FTIR«, which is the quantum optical equivalent to the classical Fourier transform spectrometer.
