1. Camera Distortion Calibration through Fringe Pattern Phase Analysis
University essay from Linköpings universitet/DatorseendeAbstract : The goal of this thesis is to use fringe-pattern phase analysis to calibrate the distortion of a camera lens. The benefit of using this method is that the distortion can be calculated using data from each individual pixel and the methodology does not need any model. READ MORE

2. Alignment of Image Sensor using Piezoelectric Crystals
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : The use of piezoelectric crystals as a way to achieve automatic alignment of an image sensor in a camera was investigated in collaboration with Axis Communications AB. Piezoelectric crystals can be created into different configurations, piezoelectric stacks being one of the simpler ones. READ MORE

3. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot.

5. Preparations for photon external beam radiotherapy treatment planning of small animals
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. READ MORE
