Precision robotic inline metrology for freeform surfaces

High precision in-line measurements on free form surfaces are considered a key factor for the industrial production of the future. Robot-based measurement systems provide the required flexibility but are typically lacking the required precision. The scope of this project is the development of a measurement platform designed as end effector for industrial robots, which carries a measurement or inspection tool and compensates for environmental disturbances, enabling precision inline measurements on arbitrarily oriented surfaces.

High-precision electrical AFM modes for biological applications 2016 - 2018

Electrical modes of Atomic Force Microscopy (AFM) allow the high-resolution mapping of surface charges on a sample with nanometer precision. A particular measurement challenge is to perform such modes on biological samples (tissue extracts, biomolecules, biomembranes, etc). To this end, the project aims to investigate different preparation and measurement approaches and a specific goal is to determine alterations of surface charge of biological fibers caused by the reaction with sugar, which has important implications in medicine and cell biology.

High resolution long range Lidar for autonomous driving (LiDcAR)

Lidar is an acronym for light detection and ranging, in analogy to radar. Lidar has received much attention in the automotive industry as a key component for high level automated driving systems. Compared to other sensing techniques such as stereo cameras and radar, lidar can provide high resolution and highly accurate 3D measurements of the surroundings and robust detection in various weather conditions.

SatComScope

This project aims to integrate adaptive optics (AO) technology into small-sized telescope systems of the industrial partner, ASA Astrosysteme, in order to enable free space optical (FSO) communication between satellites and optical ground stations. Compared to radio-frequency communication, this yields a potential increase of the data rate of more than 1 order of magnitude, while simultaneously significantly reducing the emitting power and weight on the satellite.

Scanning optical point- and line-sensor (SOS)

To overcome the limitation for better productivity and reliability of production in this project, a rotating or steering mirror scans the sensor’s optical point or line over a product surface, targeting triangulation, confocal, and color sensors. Weiterlesen →

Characterization of highly divergent optics (DOC)

Opto-mechatronic devices such as triangulation sensors or chromatic confocal sensors project focused light beams onto the surface of the measuring object. Assessing the properties of the focused beam is essential as they are directly related to the achievable measurement resolution and precision of the opto-mechatronic device. Weiterlesen →

Atomic Force Microscopy capable of vibration isolation (Vibrostop AFM)

An atomic force microscope (AFM) can image and inspect a sample surface with high resolution by scanning a probe with a sharp tip over the sample. During scanning, the vertical position of the probe with respect to the sample typically needs to be regulated with nanometer resolution. For the required high resolution, AFMs are sensitive to vibrations transmitted from the floor dependent on their design. Weiterlesen →
