1. 16. Flight dynamics multi-mission software development for optical link planning and execution

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Giacomo Dal Toso; [2023]
   Keywords : Generic Planning Tool; Visibility Service; Link Support Service; Visibility Windows; Flight Dynamics; Mission Planning;

   Abstract : The Generic Planning Tool (GPT) is a new software package being developed by the Flight Dynamics team at DLR. In an era where laser communications are becoming more and more relevant to data transmission for space missions, the GPT’s purpose is to compute highly accurate visibility windows and provide a wide variety of support information for both satellite-to-ground and inter-satellite links.

3. 17. Photoluminescence Mapping of Erbium Doped Lithium Niobate

   University essay from KTH/Tillämpad fysik

   Author : Chuanshi Xie; [2023]
   Keywords : Automotive mapping; Erbium emitters; Ion implantation; Lithium niobate on insulator; photoluminescence microscopy; Automatisk kartläggning; Erbium fotonemitterare; Jonimplantation; Litiumniobat på isolator; fotoluminiscensmikroskopi.;

   Abstract : Lithium niobate (LiNbO3) is a human-made crystalline which is widely used in modern photonics due to its useful properties. In recent years, there has been significant progress in the development of lithium niobate on insulator (LNOI) technology, realizing a fully functional photonic integrated circuits, thanks to its capabilities in both electro-optics and second-order optical nonlinearity.

4. 18. Investigation of above-ground biomass with terrestrial laser scanning : A case study of Valls Hage in Gävle

   University essay from Högskolan i Gävle/Samhällsbyggnad

   Author : Mathias Billenberg; [2023]
   Keywords : TLS; tree species; QSM; AGB; volume; wood density; biomass; allometric; point cloud;

   Abstract : The thesis investigates above-ground biomass (AGB) with terrestrial laser scanning (TLS) for estimating AGB in a study area in Valls Hage, Gävle. The study used TLS for field measurements to collect highly detailed point clouds of two tree species for AGB estimation and comparison against validation data. READ MORE

5. 19. UV laser patterning of silicone-based soft electrode grids

   University essay from Linköpings universitet/Institutionen för teknik och naturvetenskap; Linköpings universitet/Tekniska fakulteten

   Author : Maria Jakobsson; [2023]
   Keywords : Soft electrodes; Wearable electrodes; UV laser; Laser ablation; Laser curing; Polydimethylsiloxane; PDMS; Silver flakes; Teknisk biologi; Teknisk biologi;

   Abstract : Roughly 123 million people worldwide are affected by conditions such as epilepsy, dementia, and cardiovascular diseases. Wearable electrodes are currently used to monitor these conditions short-term. Long-term monitoring would allow for predicting seizures and could be used as a preventive treatment. READ MORE

6. 20. Laboratory starlight simulator for future space-based heterodyne interferometry

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : William Karlsson; [2023]
   Keywords : Angular resolution; Astronomy; Coherence length; Digital delay lines; Fiber optical circuit; Heterodyne interferometry; Interference; Laboratory starlight simulator; NIR light Near-Infrared ; Optical path differences; Space exploration; Starlight; Testbed environment;

   Abstract : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. READ MORE
