1. 1. Multi-camera system for close-up supervision in test-fixtures using openCV and optics

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Henrik Liljefors; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The test-fixture is a device used for testing of electronic circuits in production, that is produced by the Lund based company mikrodust AB. In the test-fixture, cameras are both used for supervision of products-in-testing and in the products themselves. LÄS MER

3. 2. The development of a Hardware-in-the-Loop test setup for event-based vision near-space space objects.

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Rik van den Boogaard; [2023]
   Nyckelord :Camera optics; Event-based camera; HASTE; Hardware-in-the-Loop testbench; Harris corners; KLT; Asteroid; Frame-based camera; Near-space objects; Planetary exploration; Space-simulated conditions;

   Sammanfattning : The purpose of this thesis work was to develop a Hardware-in-the-Loop imaging setup that enables experimenting with an event-based and frame-based camera under simulated space conditions. The generated data sets were used to compare visual navigation algorithms in terms of an event-based and frame-based feature detection and tracking algorithm. LÄS MER

4. 3. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Robert Petersen; [2023]
   Nyckelord :Spatial Light Modulation; Phase Retrieval Algorithm; Focal Spot Optimization; Adaptive Optics; Wavefront Sensing; Lasers; Physics and Astronomy; Technology and Engineering;

   Sammanfattning : 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. 4. Construction and development of a low-cost hyperspectral imaging system

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Nikita Grigoriev; [2022]
   Nyckelord :Hyperspectral Imaging; Pushbroom;

   Sammanfattning : Quantification of spectral data is of great interest in many fields of science, since it can provide further insight into other properties of an object. However, traditional cameras are usually made to image the world in a similar fashion as to how we see it, wherefore they are usually not fit to record nor measure further spectral information.

7. 5. Design and Construction of a Multi-Port Beamsplitter Based on Few-Mode-Fibers

   Master-uppsats, Linköpings universitet/Informationskodning

   Författare :Daniel Spegel-Lexne; [2022]
   Nyckelord :beamsplitter; spatial modes; Space division multiplexing; superpositions; LP-modes; few-mode fibers; multi-mode interference; self-imaging; heterogeneous fiber structures; quantum communication; quantum optics;

   Sammanfattning : A MBS (Multi-port beamsplitter) for higher dimensional quantum communication has been designed and constructed and the theory and method for this is presented in this thesis. It uses optical fibers in a heterogeneous structure with a single-mode fiber spliced to a multi-mode fiber and then spliced to a few-mode fiber. LÄS MER
