Recognizing things three-dimensionally, evaluating spatial situations, orientation in the environment – these are human abilities enabled by the interaction between our eyes and our brain. For applications in medicine and industrial engineering, there is a high demand for technical systems with comparable abilities. Detailed 3D imaging information with high measurement speed and precision is of specific interest in scientific research.

Researchers from the Fraunhofer Institute for Applied Optics and Precision Engineering IOF and the Friedrich Schiller University Jena developed an imaging technique that works at a speed 50 times higher than the current best available technology. By combining completely novel high-speed sample projection principles like LED-based array projection with new analysis methods, a technical bound of optical 3D measuring systems that had existed for years could be lifted. 700 3D images per second were captured and processed already in the labs of the Fraunhofer Institute and the University.

In the future, this will allow for systems measuring highly dynamic processes with the highest precision.  The new abilities will be proven as especially impressive in the automotive industry with the 3D recording of cars in crash tests. Like this, this new method adds to improved vehicle safety. Furthermore, in particularly fast production processes with a high number of cycles, highly dynamic 3D imaging can help avoid manufacturing errors and reduce costs.
