The Department of Signatorics at Fraunhofer IOSB in Ettlingen has an opening for:
Image Processing for Turbulence Mitigation
The position is based in the Adaptive Optics Group, where research themes revolve around imaging through turbulence (especially along horizontal paths and strong turbulence) and free-space laser communications. The team develops simulations, theoretical models, image processing software and adaptive optics systems.

Long-range surveillance has numerous military, security, and navigation applications. Most electro-optical systems used for this purpose are operated in the lower atmospheric boundary layer and therefore their performance is highly affected by atmospheric phenomena such as rain, fog, scattering, absorption and turbulence. That last of these detrimental effects is the focus of the international project “Development of Software-Based Atmospheric Turbulence Mitigation Demonstrator” coordinated by the European Defence Agency.
In the context of the project, Fraunhofer IOSB aims to develop novel algorithms for turbulence mitigation and to create standalone software capable of real-time or near real-time execution on video sequences corresponding to a wide a range of turbulence strengths.
- M.Sc. or equivalent experience in Electrical Engineering, Computer Science or Natural Sciences
- In-depth knowledge of the foundations and current state-of-the-art solutions in the field of image processing
- Experience with at least one high-level programming language
- A demonstrated record of original thinking (through e.g. scientific publications, technical reports or patents), and the ability to conduct research both independently and collaboratively
- Experience with hardware programming (FPGA or GPU) is desirable
The incumbent will be tasked with putting forward, implementing and testing algorithms meant to alleviate the following problems caused by atmospheric turbulence in long-range imaging:
- temporally and spatially varying warping and blurring
- global image shifts
- loss of contrast
- decrease in signal-to-noise ratio
- discrimination between real moving objects and apparent motions caused by turbulence
They will start with literature research and familiarize themselves with the already available high-level software. When commensurate with the candidate’s experience in low-level / hardware programming, subsequent tasks would include real-time implementation of the existing algorithms in hardware and developing interfaces to imaging sensors. Alternatively, incumbents with demonstrated research skills in image processing would be encouraged to propose and validate their own approaches to turbulence mitigation, exploring novel solutions normally falling into such general categories as: image stabilization, block matching, optical flow, deconvolution and “lucky imaging”.
The incumbent is also expected to publish papers and give presentations at international conferences.
