Investigation of the Sensitivity of Infrared Thermography (IRT) for De-tecting Local Surface Defects on Rotor BladesSurface disturbance elements such as erosion or contamination can significantly impair the aerodynamic performance of rotor blades and reduce the energy efficiency of wind turbines. Therefore, early and reliable detection of small surface defects is highly... » more

Evaluation of Direct and Indirect Flow Sensing Methods Using Miniaturized DronesFollowing the Wind – Measuring the Unknown? Utilizing miniaturized drones for flow measurements extends the application areas and possibly enhances the measurement accu-racy compared to larger drones due to the less distortion on the measuring flow. » more

Development and investigation of a sensor fusion real-time method for drilling of inhomogeneous materialsAs part of a top-level German research project, the BIMAQ is working on the application of sensor data fusion techniques in manufacturing processes. For this purpose, a test bench for drill-ing inhomogeneous materials is being developed. » more

Research and application of optical distance sensors for drilling im-plant holes in boneAs part of a top German research project, BIMAQ is working on determining the drill channel length when drilling holes for screwing bone implants, as the strength of the screw connection depends on selecting the correct screw length. Optical distance sensors will... » more

Development of an Algorithm for Correcting Image Shifts in Optical Flow Measurements in Grinding ProcessesTilted View – Clear Results? In optical flow measurement techniques such as Particle Image Velocimetry (PIV), image quality is crucial for the accurate calculation of velocity fields. To enable optical access to, for exam-ple, the coolant flow during grinding... » more

Tool deflection measurement in incremental sheet forming using an optical multi-sensor systemThe innovative process of incremental sheet forming is associated with high form deviations resulting, among other things, from the deflection of the forming stylus. For this reason, the tool deflection has to be detected with an optical measuring system... » more

Optical modelling and simulation of light scattering and absorption effectsIs it possible to optically detect the air surrounding a compo-nent and thus indirectly predict the component geometry? The basic idea behind indirect optical geometry measure-ment is to no longer measure the surface of the object to be measured directly, but... » more
-
Movement of microparticles by means of optical beam pressureTweezers made of light? Within the framework of a top European research project, completely new ways of measuring geometry and surfaces are to be explored using an indirect optical measurement approach. The basic idea is not to measure the surface of the object... » more

Drone-Based Laser Triangulation System for Geometry Measurement of Local Surface DefectsThe regular inspection of structures, such as bridges or wind turbines, for surface damage is essential for condition assessment and planning maintenance tailored to specific needs. However, existing solutions always represent a compromise between measurement... » more

In-process analysis of laminar-turbulent transition at wind turbinesHave you ever wondered why wind turbines sometimes don't turn even though it's windy? The answer may depend on the flow conditions at the rotor blades. This flow can be visualized by thermography from a great distance and without stopping the wind turbine. For... » more

Evaluation and Development of prediction methods for renewable energy generation on the basis of weather dataHow can weather data be used to predict the power generated by both wind and solar energy? This question is to be answered concretely for the Bremen-Oldenburg region within the framework of the hyBit project in order to produce so-called green hydrogen. The aim... » more
