The core competencies reach from design of optical systems and the development of specialized signal processing algorithms all the way to questions concerning the automated planning of measurements and the integration of sensors into multi modal and multi scale measurement strategies. For this purpose various commercially available simulation tools are routinely applied for the characterization and optimization of sensor systems. These simulation tools are supplemented by custom build extensions or in house developed simulation tools wherever necessary. All measurement systems and the respective signal processing algorithms are developed within an Open-Source software environment that is being developed at the institute, thereby guaranteeing industry ready prototypes.
