  1. 41. Design of a variable focal length optics for a SWIR Earth observation camera

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Sergio David Díaz Martínez; [2021]
    Keywords : ;

    Abstract : This thesis consists of a preliminary design study of a variable focal length optics for a SWIREarth observation camera which is planned to be placed inside a 6U Cubesat. After thesuccess of DRAGO instrument consisting on a SWIR camera onboard a Cubesat, which hasbeen recently launched (January 2021), the Institute of Astrophysics of the Canary Islands(IAC) began this project with the intention of adding zoom optics to SWIR space imagingsystems.

  3. 42. Indoor VLC behaviour  with RGB spectral power distribution using simulation.

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Siva Babu Ajjapu; Sasank Reddy Lokireddy; [2021]
    Keywords : ;

    Abstract : n recent years visible light communication (VLC) has been one of the technologies overgrowing in this competitive world and breaking through the wireless transmission of future mobile communications. This VLC replaces radio frequency (RF), which has several important features like large bandwidth, low cost, unlicensed spectrum. READ MORE

  4. 43. 3D-Printed Geodesic Luneburg Lens Antenna With Novel Patch Antenna Feeding

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

    Author : Elin Berglund; Sandis Freimanis; [2021]
    Keywords : Luneburg lens; patch antenna; geodesic; transformation optics; 3D-printing;

    Abstract : With the roll out of new technologies and the worldbecoming more connected, there is a rising demand for higherbandwidth and new frequency bands. To meet the demand,higher frequencies are used in new communication systems.Higher frequencies come with the need for new antenna designsand one promising type of antenna is the lens antenna.

  5. 44. Characteristics and Applications of One Dimensional Single Photon LiDAR

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Carlo Ninic Svensson; Viktor Berger; [2021]
    Keywords : ;

    Abstract : A challenge when working with optics systems is identifying and locating errors and irregularities in an effective and non-time consuming manner. Getting a view of how light interacts with every individual component in a complex optical system would streamline this process. READ MORE

  6. 45. Study of an automated testing procedure with dynamic job scheduling and automatic error handling

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Tom Andersson; [2021]
    Keywords : Automation; Testing; Dynamic job scheduling; Automatic error handling; Concept generation; Heuristic rules; Dispatching rules; Branch and bound; A*; Dynamic programming; Beam search; Genetic algorithms; Tabu search; Simulations; C#; Technology and Engineering;

    Abstract : During the production of Axis's cameras, the optics modules have to do a number of tests and calibrations that are performed in different test stations. The test and calibration sequence differs between different models. This has so far been done manually by having operators move the units between test stations. READ MORE
