1. Real-time Autofocus Algorithm in Laser Speckle Contrast Imaging
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Microcirculation is defined as the blood flow in the smallest blood vessels. Laser speckle contrast imaging (LSCI) is a full field imaging technique that provides instantaneous 2-D perfusion maps of illuminated tissues based on speckle contrast. LÄS MER
2. Contribution to the Understanding of the Effects of Propagation through the Ionosphere of P-band SAR Data
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : The BIOMASS mission from the European Space Agency (ESA) is designed to measurebiomass and carbon content in Earth’s forests. To account for phase changes caused byionospheric variations, a map-drift autofocus algorithm is developed, which utilises a phasescreen of the ionosphere to eliminate phase errors in the signal.

3. Comparison of Autofocus Methods for Highly Reflective Surfaces : A Case Study on the Inspection of Optical Filters
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Visual inspection is a crucial final step when manufacturing products, as it determines if a product can be sold or rejected. The inspection is often performed manually by trained inspectors, which is time-consuming and often subjective. By automating the inspection, it can be performed faster and more accurately. LÄS MER
4. Development of a tool to analyze back-focus characteristics of fix-focal cameras
Master-uppsats, Lunds universitet/InnovationSammanfattning : Fix-focal cameras require careful alignment of the sensor relative to the lens during assembly in order to produce a sharp image. Axis developed wide- and fish-eye network cameras are, for a number of reasons, focused at infinity when aligned. LÄS MER
5. Towards the Performance Assessment of aMapdrift Autofocus for a P-Band SARMission Implementation
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : In the context of the ESA BIOMASS mission in which for the first time, a P-Band SAR sensor isgoing to be mounted into a spaceborne system. With its penetration capability, it will contributeto the measurement of the biomass and carbon content in the Earth’s forests. LÄS MER
