  1. 11. Practical Trials of Fiber Optical Gyroscope Based Inertial Navigation System

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Tim Djärf; [2023]
    Keywords : Technology and Engineering;

    Abstract : There exists a need for inertial navigation systems within a multitude of applications, such as drones, unmanned vehicles, and guidance systems. Saab produces gyroscopes for stabilization purposes, but the gyroscopes could also be used as part of an inertial navigation system. READ MORE

  3. 12. Development and Analysis of a Gaseous Hydrogen-Oxygen Rotating Detonation Combustor

    University essay from KTH/Kraft- och värmeteknologi

    Author : Birgir Steinn Hermannsson; [2022]
    Keywords : ;

    Abstract : Theory suggests that more efficient rocket propulsion can possibly be achievedby utilizing a pressure-gain detonative combustion process instead of conventional deflagration combustion. To demonstrate this, rotating detonation engines that sustain one or several detonation waves in an annular enclosure havebeen a subject of research for decades. READ MORE

  4. 13. Optical Detector for Microfluidics

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Carlos Gómez Jiménez; Jaime Gómez Jiménez; [2022]
    Keywords : Serial crystallography; Microfluidic device; Optical detector; Particle counting;

    Abstract : This project arose from the need to filter the sampled data and eliminate non-useful information in Serial Crystallography in Microfluidic Device (MFD)by using a portable optical detector placed around the channel. By testing sixteen different configurations, always using an LED as a source and a photodiode as a light sensor, changes in the channel due to the passage of air bubbles were detected. READ MORE

  5. 14. Investigation and evaluation of optical distance sensors

    University essay from Uppsala universitet/Signaler och system

    Author : Olof Wigzell; [2022]
    Keywords : optics; radiometry; senssor; microcontroller; irradiance; circuit design; calibration; validation;

    Abstract : Optical sensors are among the sensors that are often used for distance measurements. An optical distance sensor is basically made of a light emitter (Tx) such as a light emitting diode (LED), a light receiver (Rx) such as a photosensitive transistor, and a circuit supporting the operation of the Tx and Rx.

  6. 15. Automatic Calibration of Camera Parameters : A Steppingstone to Analysing Videos

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Wilma Hallén; [2022]
    Keywords : Smartphone; Video stabilisation; Calibration;

    Abstract : The smartphone is commonly used for image and video capture. Due to the lightweight of the smartphone, small handshakes are noticeable in recorded videos. The image sensors in smartphones are typically CMOS, which introduces rolling shutter artefacts. Stabilisation is introduced to minimise the effects of the camera movement and artefacts. READ MORE
