High-Tech Imaging in Scattering Media for Medical Applications
Fraunhofer IPMS is collaborating with research and industry partners to develop state-of-the-art optoelectronic sensor technologies.

Fraunhofer Institute for Photonic Microsystems IPMS is advancing next-generation optoelectronic sensor technologies through the OASYS joint project (Optoelectronic Sensors for Application-Oriented Systems for Life Sciences and Intelligent Manufacturing). In collaboration with leading research institutions and industry partners, the institute is developing compact, energy-efficient, and highly integrated sensor components that address key challenges in life sciences and smart manufacturing.
A central focus is the flagship Project B1, MEMS-based Imaging in Scattering Media, which utilizes novel spatial light modulators (SLMs) to achieve high-resolution optical imaging in complex environments such as biological tissue. These MEMS-based SLMs—featuring thousands to millions of high-speed, individually controllable micro-mirrors—enable precise phase modulation of light, making it possible to correct wavefront distortions caused by scattering, absorption, or reflection.
This technology significantly improves imaging depth and clarity in highly scattering media, supporting advanced optical techniques such as deep-tissue microscopy and endoscopy. The resulting systems are expected to enable earlier and more accurate non-invasive diagnostics, enhanced cancer detection, improved treatment monitoring, and broader capabilities for biomedical research.

Advancing Optoelectronic Sensing for Industry and Life Sciences
Within OASYS, Fraunhofer IPMS acts as the central research partner, contributing its expertise in microelectromechanical systems, photonics, and adaptive optics. The project centers on two main research directions:
- MEMS-based hyperspectral imaging for industrial and agricultural applications, enabling precise material analysis and quality control.
- High-resolution optical systems for the life sciences, with a strong focus on imaging through scattering media using adaptive wavefront correction.
The OASYS project is funded with approximately €12.5 million by the German Federal Ministry for Research, Technology, and Space (BMFTR) and runs for five years, from 1 September 2023 to 31 August 2028. Coordinated by Brandenburg University of Technology Cottbus-Senftenberg (BTU), the consortium also includes the Ferdinand Braun Institute (FBH) and the IHP – Leibniz Institute for Innovative Microelectronics.
