The Digital Map Table - a new approach in the shared situation visualization and analysis.

"beAWARE" offers improved decision support for extreme weather and climate events. The project work resulted in an integrated solution for forecasting, early warning, transmission and forwarding of emergency data.

In the KARLI project, IOSB is developing occupant state detectors for interactions in the vehicle interior.

The "WaterFrame®" project forms the basis for the cooperative development of watercourse information systems.

Fraunhofer IOSB is a partner in the SM4RTENANCE project to enable a federated neutral cross-sector data space, resulting in the development of interoperable circular twins and integration between data spaces

Data is collected in the vineyard using a combined system of quad bike, drone and calibrated markers in order to develop a systematic monitoring procedure.

Fraunhofer IOSB has developed an autonomous surface vehicle that autonomously takes measurements above and below the water to generate associated 3D maps.

To facilitate faster data transfer between astronomical equipment in space and base stations on Earth, optical communications links can be deployed. Among the design challenges faced when designing deep space communications are: very low power of received signals, the effect atmospheric turbulence on propagating signals, and strong presence of background light from the Sun, which varies over the course of the day. To cope with these challenges, deep space optical communications require adaptive optics (AO) systems to maximize the number of received signal photons, as well as exceptionally narrow bandwidth optical filters to remove background noise from received signals.

Despite the availability of significantly higher bandwidth, the underwater environment poses challenges to the design of optical communications systems. In clean ocean water, extinction due to absorption and scattering very strong, and limits the useful range of underwater communications to ∼100 m in the blue-green spectral window. Additionally, underwater optical turbulence stemming from minute differences in water’s refractive index and salinity perturbs the transmitted laser beams effecting the fidelity of received signals. In the Adaptive Optics group at Fraunhofer IOSB, we study the effect of underwater optical tur-bulence on transmitted laser light and try to compensate the effects of turbulence using adaptive optics systems.

As an alternative to the Shack-Hartmann wavefront sensor, holographic wavefront sensors (HWFS) provide the potential for significantly increased bandwidth capabilities as well as insensitivity to obscurations. The HWFS consists of two main components: a holographic diffractive optical element (DOE) and a small detector array.
