1. Partially Coherent Laser Radiation - Modeling and Application to Optical Microlithography
Sammanfattning : This work deals with a type of light that has properties somewhere between blackbody radiation and conventional laser light; such light is referred to as partially coherent. One example is the radiation from the pulsed excimer laser, which is used in the manufacturing of most of the worlds integrated circuits. LÄS MER
2. Image Analysis and Enhancement with Applications in Medicine
Sammanfattning : This thesis consists of six parts in which methods for image analysis and processing are studied. Two-dimensional medical images, image sequences, and three-dimensional image volumes are considered. LÄS MER
3. Statistical optics and optical elements for microtechnologies: Partial coherence, lithography and microlenses
Sammanfattning : The scientific problems treated in this thesis are expressed within the framework ofstatistical optics and are generated out of the optical lithography industry. Opticallithography uses partially coherent light, i.e. light with a random wavefront, toincrease the performance of the lithographic process. LÄS MER
4. Multiplexed Digital Holography incorporating Speckle Correlation
Sammanfattning : In manufacturing industry there is a high demand for on line quality control to minimize the risk of incorrectly produced objects. Conventional contact measurement methods are usually slow and invasive, meaning that they cannot be used for soft materials and for complex shapes without influencing the controlled parts. LÄS MER
5. Combined Digital Holography and Speckle Correlation for Rapid Shape Evaluation
Sammanfattning : In manufacturing industry there is a high demand for on line quality control to minimize the risk of incorrectly produced objects. Conventional contact measurement methods are usually slow and invasive, meaning that they cannot be used for soft materials and for complex shapes without influencing thecontrolled parts. LÄS MER
