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

Strain behavior of bio-inspired light weight gearsIn the course of material- and resource-saving product design gears with bio-inspired leight weight structure are being investigated for the first time. These gears offer the opportunity to specifically damp high loads and to reduce stress peaks. This requires a... » more

Indirect optical geometry measurements with fluorescence particlesMaking the invisible visible? - With fluorescence particles! Optical measurement techniques enable fast and precise geometric measurements. However, this is only possible if sufficient light energy is reflected from the object surface to the detector. For this... » more

Generation and investigation of dry ice particles as measuring probesMicroparticles of dry ice as measuring probes? As part of a top European research project, BIMAQ is work-ing on overcoming the current limits of optical geometry measurement technology. The idea here is no longer to measure the surface of the measured object... » more

Optical defect detection in nano-structures: experimental setup, uncertainty analysis, feature detectionSurfaces with column-like nano-features exhibit many useful properties, and are referred to as a new type of metamatarial. Each nanopillar has a diameter of about 10 nm, and the pillars are distributed in a grid-like pattern. However, there is a lack of... » 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

Application studies for fluorescence-based indirect optical geometry measurementIs there an optical measuring system that can be used to precisely determine the geometry of all types of compo-nents, i.e. for all current and future materials? This question is to be answered within the framework of a highly topical European research project. » 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

Investigations into the flow behavior of microparticle seedingsFlow measurements are of growing importance in many areas of the economy and society. Particularly with regard to sustainability and energy efficiency, the flow behavior of car bodies, wind turbine blades or aircraft must be perma-nently optimized. » more

Real-time measurement of the tool pose in robot-based forming using an optical multi-sensor systemBy means of robot-based incremental forming, sheet metal parts can be formed economically and flexibly in small quantities. However, increased geometric deviations occur due to the low rigidity of the robots. To re-duce the deviations, the robot cells are planned... » 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
