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.


Geomapping maritime surfaces: Finnish research institute uses measurement systems developed by Fraunhofer IPM

The renowned Finnish Geospatial Research Institute (FGI) will use LiDAR systems developed by the Fraunhofer Institute for Physical Measurement Techniques IPM to survey maritime surfaces in the future. The state-run research unit expects this technology to deliver higher-quality geographical data and more efficient field measurements than ever before.

Laser replaces hammer: new method for testing the structural integrity of buildings

Building inspection benefits from laser-based measuring systems providing quick and accurate digital measurement data. In the future, lasers will help detect subsurface damage, too. Up until now, the only way of detecting hidden defects was the so-called impact hammer test.

Quantum sensors for brain research

Brain researchers have high hopes for quantum sensors to provide deeper insights into the brain one day. This is also a research focus of Fraunhofer IPM. Two events in December provided an insight into the topic: Professor Svenja Knappe delivered a public Carl-Zeiss-Humboldt Lecture to show how quantum sensor technology could advance brain diagnostics and therapy, and an experts’ workshop explored the topic of optically pumped magnetometers for magnetoencephalography.
