1. Ultra precision metrology : the key for mask lithography and manufacturing of high definition displays
Sammanfattning : Metrology is the science of measurement. It is also a prerequisite for maintaining a high quality in all manufacturing processes. In this thesis we will present the demands and solutions for ultra-precision metrology in the manufacturing of lithography masks for the TV-display industry. LÄS MER
2. Evaluation of the Random-LOS Measurement System for Vehicular Communication Applications
Sammanfattning : The automotive industry is progressively closing on the Telecom industry as wireless data connection and transmission become more and more important for vehicles. In both future and present cars, the safety and infotainment systems depend on reliable wireless data transmission. This is especially the case when autonomous cars will reach the market. LÄS MER
3. Development of ultra-precision tools for metrology and lithography of large area photomasks and high definition displays
Sammanfattning : Large area flat displays are nowadays considered being a commodity. After the era of bulky CRT TV technology, LCD and OLED have taken over as the most prevalent technologies for high quality image display devices. LÄS MER
4. Shape measurements using temporal phase unwrapping
Sammanfattning : This licentiate thesis is devoted to shape measurements using two different optical methods. The first one is a classical triangulation method, which uses projected fringes. The second one is a new interferometric method, which uses wavelength scanning. Both are whole field measuring methods. LÄS MER
5. Optical shape measurements using temporal phase unwrapping
Sammanfattning : This doctoral thesis is devoted to optical shape measurements using an analysis scheme called temporal phase unwrapping. This scheme makes it possible to determine the absolute distance from a detector (usually a camera’s CCD-detector) to an object. Two different optical methods are considered for this 3-D sensing.
