Measurement setup - Adaptive Optics


Fields of operation include the performance optimization of electro-optical systems (from the ultraviolet to the infrared spectral range) within the atmospheric environment as well as the improvement and development of signature management measures.

Key research areas within warning sensor technology include the characterization of environment and backgrounds as well as gathering information about potential threat signatures. The department develops warning sensor designs for a range of different threat scenarios as well as developing approaches for applying novel technologies in civil warning sensors.

Research projects in the field of signature management focus on the one hand on changing and/or reducing one’s own signature and thus reducing detectability and on the other hand on evaluating possible enemy camouflage and deception measures. Ground and air supported measurement processes are being developed and deployed in airplanes and helicopters in complex measurement campaigns over land and sea. New kinds of laboratory and field measurement equipment are used to define relevant material and system characteristics and use them in numeric simulations to evaluate signatures.

One topic necessary to all areas of research within the department is the investigation into the effects of tmosphere on electro-optical systems. In the field of environmental limitation the department uses comprehensive data gathered over the years concerning limiting factors such as atmospheric refraction and turbulence. These measurements form the basis for evaluating atmospheric influences on sensors with the objective of correcting these as far as possible.
