  1. 1. Achieving Optimal Alignments of IR Source and Detector in Waveguide Based Gas Sensor

    University essay from KTH/Medicinteknik och hälsosystem; KTH/Medicinteknik och hälsosystem

    Author : Sefik Güler; Agbai Randolph Agwu; [2020]
    Keywords : Non-dispersive infrared technology; microelectromechanical systems; infrared light; electromagnetic spectrum; gas sensor; light emitting diode; photodiode detector; Icke-dispersiv infraröd teknologi; mikroelektromekaniska system; infrarött ljus; elektromagnetiskt spektrum; gassensor; lysdiod; fotodioddetektor;

    Abstract : I takt med att tekniken för mikroelektromekaniska system utvecklas uppkommer det nya områden för tillämpning. Ett område är inom gassensorer där icke-dispersiv infraröd strålning används genom att mäta absorptionen hos olika gaser för att bestämma mängden av en specifik gas i luften. READ MORE

  2. 2. Optical communication with underwater snake robots : Design and implementation of an underwater wireless optical communication system

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Jaime Marco Rider; [2019]
    Keywords : optical communications; underwater wireless; robot communications;

    Abstract : 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. READ MORE

  3. 3. Automated noise measurements for very long wavelength infrared detectors

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Ramos Santesmases; [2019]
    Keywords : Noise; Infrared detector; QWIP; T2SL; Brus; Infraröd detektor; QWIP; T2SL;

    Abstract : The potential imaging performance of infrared (IR) detectors is dependent on the noise level in the detector pixels. Noise measurements at pixel level can therefore provide basic understanding of the intrinsic limitations of detectors. READ MORE

  4. 4. Implementing a Probe with Laser Doppler and Heater

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Karin Marneson; [2017]
    Keywords : ;

    Abstract : With laser Doppler flowmetry, blood flow can be measured in the smallest blood vessels in the body. Perimed AB is a company that develops instruments for microvascular diagnostics and want to develop a 15-mm probe with laser Doppler and heater. READ MORE

  5. 5. Characterization of single InP Nanowire-based Avalanche Photodetectors

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Virginia Boix De La Cruz; [2016]
    Keywords : Photodetectors; Nanotechnology; Nanowires; IndiumPhosphide; Semiconductors; Physics and Astronomy;

    Abstract : Nanoscience is an emerging field of technology where the bottom-up fabrication techniques are utilized instead of the traditional top-down approaches for enhancing the performance of di erent optoelectronic devices. One such material is a semicon- ductor nanowire (NW) which holds immense potential in nanophotonic applications, such as solar cells, LEDs, lasers, sensors and photodetectors. READ MORE
