1. Constructing and Commissioning HELIOS – A High Harmonic Generation Source for Pump-Probe Measurements with sub 50 fs Temporal Resolution : The Development of Experimental Equipment for Extreme Ultraviolet Spectroscopy
Sammanfattning : This thesis presents HELIOS, an in-house laboratory for time-resolved pump-probe spectroscopy with extreme-ultraviolet (XUV) probe radiation. A wide span of pump wavelengths can be generated using commercial laser equipment while XUV probe radiation is generated via a high harmonic generation process in a noble gas delivering probe photons with energies between 20 eV and 72 eV.

2. Gaining Depth : Time-of-Flight Sensor Fusion for Three-Dimensional Video Content Creation
Sammanfattning : The successful revival of three-dimensional (3D) cinema has generated a great deal of interest in 3D video. However, contemporary eyewear-assisted displaying technologies are not well suited for the less restricted scenarios outside movie theaters. LÄS MER
3. Detector Considerations for Time-of-Flight in Positron Emission Tomography
Sammanfattning : Positron-Emission-Tomography (PET) is a modern imaging technique in nuclear medicine providing quantitative 3D distribution of a radioactive tracer substance in the human body. The gamma-detector is the first link in the chain of components that constitutes a PET. LÄS MER
4. On the Challenges for Time-of-Flight Electron Spectroscopy at Storage Rings
Sammanfattning : Time-of-flight (TOF) techniques for energy analysis have been common in electron spectroscopy for many decades. TOF-based electron spectrometers benefit from higher transmission and information rate compared to their main competitor: the hemispherical analyser; the drawback being their lower energy resolution.

5. Time of Flight Estimation for Radio Network Positioning
Sammanfattning : Trilateration is the mathematical theory of computing the intersection of circles. These circles may be obtained by time of flight (ToF) measurements in radio systems, as well as laser, radar and sonar systems. A first purpose of this thesis is to survey recent efforts in the area and their potential for localization. LÄS MER
