PhD Scholarship in Real-time contact-less vibration detection in lithography systems

Project description:
The PhD position is aimed for design and application of a real-time contact-less distributed vibration detection system based on Near-field acoustic holography (NAH). NAH is a well-known sound source identification technique based on measurements with an array of microphones on a plane (hologram plane) close to the source surface. The array data is then transformed to obtain not only the sound pressure but also the vibration velocity distribution on the source surface. This makes NAH a potentially powerful method for contactless vibration detection. The goal of this PhD project is to extend the NAH formulation to confined spaces and investigate the potential of acoustic array measurements for distributed vibration detection in lithography systems, both numerically and experimentally. For successful accomplishment of the project, a PhD candidate must address problems of sound wave propagation, acoustic field modeling in confined spaces, acoustic signal processing and

inverse acoustics. The PhD student will work in close co-operation with the companies, which are responsible for the embedded system development and its application in motion control.

RequirementsA candidate for this challenging position should have a Master’s degree or equivalent in Mathematics, Electrical Engineering, Mechanical Engineering or in Applied Physics. He/she should have a strong interest in engineering acoustics and acoustic signal processing and affinity with embedded system design and motion control.
