1. Investigation and evaluation of optical distance sensors
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och systemSammanfattning : 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.

2. Image simulations of the mission Martian Moons eXploration
Master-uppsats, KTH/RymdteknikSammanfattning : Martian Moons eXploration is a JAXA-lead mission aiming at exploring the moons of Mars, Phobos and Deimos. The hyperspectral infrared camera provided by France should perform global mapping of Phobos at high resolution in order to characterize surface composition and therefore help determine the origins of the moons.

3. Precision Closed-Loop Laser Pointing System for the Nanosatellite Optical Downlink Experiment
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : The use of advanced small-satellite platforms has become increasingly more popular in the recent years. Several private companies are investing enormous capital into constellations of small satellites that are designed to provide highly data-intensive global services, such as rapid Earth imaging or fast worldwide Internet access.

4. Study of radiometric variations in Unmanned Aerial Vehicle remote sensing imagery for vegetation mapping
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Unmanned Aerial Vehicles (UAVs) provide a flexible method for acquiring high-resolution imagery with relative simple operation and cost-effectiveness. This technology emerged 30 years ago and it is widely used by commercial, scientific, and military communities due to its versatility. However, new technology brings new challenges. LÄS MER
