  1. 1. Laser dazzling of CMOS imaging sensors using amplitude modulated and continuous wave lasers

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Johan Fjellström; [2023]
    Nyckelord :;

    Sammanfattning : Protecting sensitive information is important, especially in defence applications. As cameras become more common, developing countermeasure systems that limit the information gathering capabilities of imaging sensors would be beneficial. LÄS MER

  3. 2. Forward Modelling of Ground Based SST Telescope Images

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Anna Hidalgo Larsson; [2021]
    Nyckelord :SST; SSA; Satellite; Telescope; CMOS; TLE; Image Simulator; Space Imagery; Space Debris; Tracklet; Rymdlägesbild; satellit; teleskop; CMOS; TLE; bildsimulator; rymdbilder; rymdskrot; satellitpass.;

    Sammanfattning : Space debris is becoming an increased threat to the future use of space orbits. In order to counteract this threat, the field of Space Situational Awareness (SSA), and the sub-field Space Surveillance and Tracking (SST), have been developed to gather knowledge about the space debris and satellites surrounding Earth.

    Nyckelord :Moon; TLP; Transient Lunar Phenomena; Image Processing; GPU; Nanosatellite; CubeSat; Nvidia Jetson Nano; OpenCL; CUDA; Telescope; Payload Concept; C C ; background subtraction; connected component labelling; FPGA;

    Sammanfattning : For 500 years transient light phenomena (TLP) have been observed on the lunar surface by ground-based observers. The actual physical reason for most of these events is today still unknown. LÄS MER

  5. 4. Simulation of Optical Aberrations for Comet Interceptor’s OPIC Instrument

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Maximilian Bührer; [2020]
    Nyckelord :simulation; camera; lens effects; optical aberrations; optics; ray tracing; sensor noise; coma; astigmatism; chromatic aberration; motion blur; rolling shutter; CMOS; CCD;

    Sammanfattning : In space exploration optical imaging is one of the key measurements conducted, with a vast majority of missions heavily relying on optical data acquisition to examine alien worlds. One such endeavor is ESA’s F-class mission Comet Interceptor, a multi-element spacecraft expected to be launched in 2028. LÄS MER

  7. 5. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Hamid Yadegar Amin; [2020]
    Nyckelord :5G Phased array mm-wave FR2; Technology and Engineering;

    Sammanfattning : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios. LÄS MER
