  1. 1. Robo-tographer : A Remote-Controlled Camera Gimbal

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Ibrahim Dali Abo; [2023]
    Nyckelord :Mechatronic; Arduino; Robotics; Servo-motor; wireless; Mekatronik; Arduino; Robotik; Servo-motor; trådlös;

    Sammanfattning : This report aims to evaluate a wirelessly controlled robotic arm mounted on a 3-wheel platform that would act as a stabilized camera gimbal. The evaluation is focused on doing experiments to determine the accuracy and repeatability of the robotic arm and to examine if the arm can self-stabilize. LÄS MER

  3. 2. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

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

    Författare :Jannek Hansen; [2021]
    Nyckelord :Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

    Sammanfattning : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. LÄS MER

  4. 3. Design of a Temperature Insensitive Fiber Interferometer for Long-Term Laser Frequency Stabilization using Metal Coated Fibers

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

    Författare :Saskia Bondza; [2019]
    Nyckelord :laser frequency stabilization; fiber interferometer; thermal sensitivity; optical fibers; drift-free; aluminum coated; thermal stress; Physics and Astronomy;

    Sammanfattning : This work presents the design for a temperature drift-free path imbalanced ber interferometer for long-term laser frequency stabilization using coated bers with different thermal drift. For this purpose, single acrylate, dual acrylate, copper and aluminum coated bers are analyzed theoretically and experimentally regarding the thermal sensitivity of their optical path length.

    Nyckelord :Ultrasound Optical Tomography; Deep Tissue Imaging; Monte Carlo Simulation; Spectral Hole Burning; Physics and Astronomy;

    Sammanfattning : Ultrasound Optical Tomography (UOT) is a proposed technique, which combines ultrasound imaging and optical imaging in a new way to detect, e.g. LÄS MER

  7. 5. Towards the carrier-envelope phase stabilization of a16 TW 4.5 fs laser system

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Emil Thorin; [2018]
    Nyckelord :;

    Sammanfattning : In the last decades the scientific development has made it possible to produce pulses with durations below the femtosecond time scale (1 fs = 1015 s), reaching to attoseconds (1 as = 1018 s). This is the time scale of electronic motion inside atoms and molecules. LÄS MER
