  1. 1. Development of a QRNG front-end for shot noise measurement : analysis of quantum shot noise originating from photodiodes

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Martin Clason; [2023]
    Nyckelord :shot noise; quantum random number generator; photodiode; transimpedance amplifier; skottbrus; kvantslumptalsgenerator; fotodiod; transimpedansförstärkare;

    Sammanfattning : As one of the more mature quantum technologies, quantum random number generators (QRNGs) fill an important role in producing secure and private keys for use in cryptogra- phy in e.g. quantum key distribution (QKD) systems. Many available QRNGs are expen- sive and optical QRNGs often require complex optical setups. LÄS MER

  3. 2. An amplitude modulated laser rangefinder : electronic circuit design and implementation

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och system

    Författare :Fazel Naser; Stefan Morin; [2022]
    Nyckelord :Amplitude modulation; Phase shift; Laser rangefinder; Drive electronics; PCB; Colpitts crystal oscillator; Transimpedance amplifier;

    Sammanfattning : This report describes the design and implementation of a prototype for an amplitude modulated laser rangefinder, which is made on a PCB consisting of a laser module emitting light, a photodiode receiving the light reflected from the target, and other components. The design is made for the different power levels, generation of the modulation output and the reception of the signal. LÄS MER

  4. 3. System Model of an Ultra-LowPower Fluorescence Detection Micro-Device

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Yuanyuan Xue; [2020]
    Nyckelord :;

    Sammanfattning : This thesis aims to explore the power consumption limits of Complementary Metal-Oxide-Semiconductor (CMOS) fluorescent biosensors that meet the demand, a Matlab-based calculator is designed, in which users can input required system parameters (such as LED power and noise) to observe the minimum power consumption of each basic component and the constraints of the transimpedance amplifier: cut-off frequency, signal- to-noise ratio, dynamic range, etc. Thereby to provide a reference range for the next level designs of each component in the detection system.

  5. 4. Short-Wave Infrared Lidar on Atmospheric Aerosols and Insects

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Mariam Andersson; [2017]
    Nyckelord :Lidar; Scheimpflug; Time-of-Flight; Remote sensing; Atmospheric sensing; Physics and Astronomy;

    Sammanfattning : This thesis focusses on the implementation of two elastic lidar (light detection and ranging) techniques for the monitoring of atmospheric aerosols and insects at short-wave infrared wavelengths. Data acquisition software was developed for a time-of-flight system, housed in the Lund University Mobile Biosphere Observatory (LUMBO), with consideration to the intended entomological application.

  7. 5. Optisk metod för glukosmätning : En studie för framtida icke-invasiva blodglukosmätningar

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Fatemeh Amiri; Sara Nouiser; [2017]
    Nyckelord :Glukos; optisk mätning;

    Sammanfattning : Idag lever cirka 365 000 personer med diabetes i Sverige. Mätningen av blodsocker kan upplevas som besvärlig och smärtsam med den apparatur som idag finns på marknaden. Vidare måste sjukvårdspersonal vara försiktiga vid hanteringen av teststickor pga. av den smittorisk som finns i kontakten med blod. LÄS MER
