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.


Mark-free identification of logs

Timber is a valuable natural resource, which is why 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.

SPOT research project kicks off

Particulate contamination and defects on component surfaces are detected during production either through visual inspection or by rinsing the component and analyzing the rinsing fluid. This type of quality control is state of the art, but it is cumbersome and cannot be integrated into the manufacturing process. As part of the SPOT research project, Fraunhofer IPM is working together with partners to develop a novel optical inline measurement system.

Industrial application on the horizon: using digital holography to survey moving objects

Digital holography has gained momentum over the past few years. Now, the technology is also being used in industry to accurately measure the topography of objects down to several micrometers. As part of her doctoral work, Dr. Annelie Schiller from the Fraunhofer Institute for Physical Measurement Techniques IPM demonstrated that this process can also be applied to moving objects. For this research, she has been awarded the Hugo Geiger Prize for outstanding doctoral achievements in the field of applied research.
