Detection of water pollution by oil

Which parts of the water surface are contaminated with oil? Is the dike’s vegetation cover intact? Did we find ore, or some type of rock? Did someone use the nature reserve as an illegal dump site for waste?

Man questions demand a reliable distinction of specific materials. Cameras with color sensitive hyperspectral sensors and efficient, innovative processing methods can detect different these materials where the human eye cannot.

Applications for such systems exist where surfaces have to be examined – airborne for environmental monitoring and disaster management, handheld when prospecting or inspecting structures, and also as part of fixed systems such as quality control at production lines.

The human eye only recognizes three different colors across its entire range of color vision: red, green and blue. In comparison, hyperspectral sensors capture more than 100 different color values for each pixel in the image. Processing algorithms use this high spectral resolution to achieve improved distinction between materials. This in turn lowers the false alarm rate for material detection.

State of the art sensor technology even allows the capture of hyperspectral videos. The stream of data to be processed surpasses 1 gigabyte per minute. Fraunhofer IOSB’s extensive experience with large-scale hyperspectral data processing and efficient algorithms allow the results to be available in almost real-time.

Easy-to-use, intuitive and quick

The interactive analysis allows for easy extraction of information by depicting the classification results directly on top of the data stream. The real-time capabilities of these analysis methods can support problem solution in areas where immediate action is necessary.

Employing the SpectralFinder as an airborne system, it can be used for quick reconnaissance, especially for environment protection and disaster management. It is possible to detect oil pollution, weaknesses on levees caused by pest infestation or erosion, as well as illegal garbage disposal.

The SpectralFinder has a compact, lightweight hyperspectral video camera. Its mobility even allows for handheld data acquisition at close range. In quality control of bridges, for example, spectrally suspicious areas can be highlighted and samples can be taken for further analysis.

Mounting the system to a conveyer it is possible to analyze bulk goods. In mining, it is possible to separate chunks of ore from wall rock.

Controlling the SpectralFinder is very intuitive. To compute a classification, the material is recorded with the hyperspectral camera and the data is directly transferred to the software. The user, then, selects an area of interest or a specific material from a database. The following classification is computed with this information, specifically adjusted to the desired purpose. A score is assigned to every pixel in the running video stream to evaluate the similarity between the area of interest and the recorded data. If a 3D model of the scene exists, it is even possible to visualize and work with the data in a virtual laboratory on a desktop computer.

Visitors of the Fraunhofer booth on CeBIT will have the opportunity to experience the SpectralFinder in action and see the intuitive handling and fast data processing in a live demonstration.

Im Focus: Worldwide Success of Tyrolean Wastewater Treatment Technology

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.

The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...

Im Focus: Computational high-throughput screening finds hard magnets containing less rare earth elements

Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.

The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...

Im Focus: Atomic precision: technologies for the next-but-one generation of microchips

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.

In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
