1. 1. 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

3. 2. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

   University essay from KTH/Tillämpad fysik

   Author : Alexandros Bampis; [2023]
   Keywords : Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

   Abstract : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. READ MORE

4. 3. A Positioning System for Landing a UAV on a UGV in a GNSS-Denied Scenario

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Tim Wiik; [2022]
   Keywords : Sensor fusion; UAV; UGV; NIR-LED; Extended kalman filter; Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; GNSS-denied Scenario;

   Abstract : A system of an unmanned aerial vehicle (UAV) collaborating with an unmanned ground vehicle (UGV) for use in for example surveillance, reconnaissance, transport and target acquisition is studied. The project investigates the problem of estimating the relative position, velocity and orientation between the UAV and the UGV required to autonomously land the UAV on the UGV during movement.

5. 4. Single Photon LSCM in the NIR Range

   University essay from KTH/Tillämpad fysik

   Author : Klara Wallenbro; [2022]
   Keywords : LSCM; NIR; SNSPD; LSCM; NIR; SNSPD;

   Abstract : In this thesis a near-infrared laser scanning confocal microscope (NIR-LSCM) is built to operate with optimal performance at 1550nm in combination with simultaneous LED light imaging at 970nm. For detection, a camera equipped with a complementary metal oxide semiconductor (CMOS) sensor and a superconducting nanowire single photon detector (SNSPD) are used for the LED part and the LSCM part, respectively.

6. 5. Real-time characterization of fuel by Near-Infrared spectroscopy : Quantitative measurements of moisture content, ash content, heating value, and elemental compositions in solid biofuel mixtures

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Kajsa Edlund; Ali Ahmad Shahnawazi; [2021]
   Keywords : NIR; spectroscopy; solid biofuel mixtures; moisture content; ash content; heating value; elemental composition; boiler; CHP pant; CCS; CO2; emissions; NIR; spektroskopi; fasta biobränsleblandningar; fukthalt; ask innehåll; värmevärde; elementär komposition; panna; kraftvärmeverk; CCS; CO2; utsläpp;

   Abstract : The global energy demand supplies mainly from fossil fuels, which is neither sustainable nor environmentally friendly and aims to global warming. Therefore, both more investments in renewable energy sources such as bioenergy are required, as well as new technologies such as carbon capture and storage (CCS) to handle the emissions from existing combined heat and power (CHP) plants.
