  1. 1. 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

  3. 2. Kompenseringsalgoritm för löptidsmätande laseravståndsmätare baserad på Time to Digital Converter

    M1-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Jimmy Du; [2019]
    Nyckelord :TOF; TWE; Timing Walk Error; Time-Of-Flight;

    Sammanfattning : This bachelor thesis has been collaborated with Saab Dynamics AB in Karlskoga. The purpose is to analyze time-based rangefinder based on Time-to-Digital Converter with short laser pulses. Compensation will be produced for timing walk-error that is introduced by a dynamic problem. LÄS MER

  4. 3. Modellering och analys av avståndsmätare baserad på Time-to-Digital Converter

    M1-uppsats, Karlstads universitet/Avdelningen för fysik och elektroteknik

    Författare :Johan Sundelin; [2019]
    Nyckelord :Time to digital converter; Time of flight; rangefinder; TDC; Avståndsmätare; Time to digital converter;

    Sammanfattning : This bachelor thesis has been performed at Saab Dynamics AB in Karlskoga, with the purpose to design simulation models and analyze the technology study for distance measurement based on Time Of Flight (TOF) -principle. The distance measurement is implemented by short laser pulses and Time-to-Digital Converter (TDC). LÄS MER

  5. 4. Design och konstruktion av roterande LiDAR-system för 360 graders objektdetektering

    Uppsats för yrkesexamina på grundnivå,

    Författare :Simon Ask; Rickard Lindh; [2017]
    Nyckelord :Lidar; Laser; Avståndsmätning; Kartläggning; Arduino; Objektsdetektering;

    Sammanfattning : Although laser rangefinder technologies have been around for decades in military, cartography, building, industrial and research applications it is only in recent years that more generally applicable and cheaper consumer grade laser range finder sensors have become available. This project investigates the possibilities and limitations of creating a mobile 360 degree, two-dimensional obstacle detection system using off-the-shelf available electronic components. LÄS MER
