1. Indoor VLC behaviour with RGB spectral power distribution using simulation.
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskapSammanfattning : n recent years visible light communication (VLC) has been one of the technologies overgrowing in this competitive world and breaking through the wireless transmission of future mobile communications. This VLC replaces radio frequency (RF), which has several important features like large bandwidth, low cost, unlicensed spectrum. LÄS MER
2. Optical communication with underwater snake robots : Design and implementation of an underwater wireless optical communication system
Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktionSammanfattning : Eelume AS is a norwegian company that develops autonomous underwater vehicles. Their flagship model is an underwater snake robot that performs inspection, maintenance and repair operations. For the time being, Eelume has been using acoustic communications between their AUV's and the docking station, but it has a big drawback: bandwidth. LÄS MER
3. Short-Wave Infrared Lidar on Atmospheric Aerosols and Insects
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikSammanfattning : This thesis focusses on the implementation of two elastic lidar (light detection and ranging) techniques for the monitoring of atmospheric aerosols and insects at short-wave infrared wavelengths. Data acquisition software was developed for a time-of-flight system, housed in the Lund University Mobile Biosphere Observatory (LUMBO), with consideration to the intended entomological application.

4. Development of a Detector System for Detection of Thermal Neutrons from Spent Nuclear Fuel
Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : The nuclear reaction 10B(n,alpha)7Li* was utilised to develop a neutron detection system. This system has the purpose of being used to detect the thermal neutron radiation emitted by spent nuclear fuel, before it is transported to a final repository. LÄS MER
5. Performance Evaluation and Comparison of Coherent and Incoherent Receivers under Atmospheric Turbulence
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingSammanfattning : Optical free space communication system faces the major challenge because of the atmospheric condition. Signals receive in the ground station using two different types of receivers (Coherent detection and Intensity Modulation and Direct Detection (IM/DD)). LÄS MER
