Ein spiegelmatrix-basiertes optisches 3D-Messsystem für die Mikrostrukturprüfung
The goal of the work is the conception, design and validation of a new, flexible and low-priced optical surface measuring system with a resolution in the submicrometer range, i.e. for the inspection of microstructures. Quintessential point is the application of semiconductor-manufacturer Texas …

Modellbasierte dreidimensionale Fundusrekonstruktion: ein genereller Ansatz zur Integration multi-modaler Daten des menschlichen Augenhintergrundes
A multitude of imaging systems are used to assess different properties of the different tissues in the back of the eye to support the diagnostics of ocular diseases. The correlation of these data is currently only insufficiently supported by software tools. The physician therefore has to rely …

Lasermessverfahren zur Bestimmung von Geschwindigkeit und Kraftstoffverteilung bei motorischen Einspritzvorgängen
The penetration velocity of both the liquid and the gaseous phase in a direct injection Diesel spray is determined via Laser Flow Tagging (LFT) under atmospheric and elevated pressure conditions. Furthermore, the application of LFT is demonstrated for determination of droplet velocities under …

Bildgebende Multiparameter-Lasermessungen in komplexen technischen Strömungs- und Verbrennungsprozessen
In this work the origin of cycle-to-cycle fluctuations of an air guided combustion process is investigated experimentally by means of laser diagnostics. A multi-parameter measurement technique is developed, which allows for the simultaneous, instantaneous and planar detection of five quantities …

Konturnahes Laserstrahlstrukturieren für Kunststoffspritzgießwerkzeuge
A comprehensive manufacturing process with which to produce flexible, large surface and precise complex structures on flat and curved surfaces was successfully developed based on near net 3D laser structuring and implemented in the form of a fully functional demonstrational machine. The single data …

Laseroptische Untersuchungen des Verbrennungsprozesses in einem PKW-Dieselmotor
The process of the conventional diesel combustion in small-size passenger car engines is an object of research. The combustion process can be divided in the sub-processes injection, mixture formation, auto-ignition and combustion. In the present work different laser-optical measurement technologies …
