1. 1. Heterodyne Detection using Frequency-Modulated Continuous-Wave LiDAR

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Fredrik Johansson; [2020]
   Keywords : lidar; laser; light detection and ranging; heterodyne detection; homodyne detection; Physics and Astronomy;

   Abstract : Light Detection and Ranging (LiDAR) is a technique that can change the way automated systems interact with their environments. The most common LiDAR systems used in industry today are based on the concept of Time-of-Flight (ToF) and utilizes pulsed lasers. READ MORE

3. 2. Thermomechanical Design and Analysis of the Lisa Phase Measurement System

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Pablo Martinez Cano; [2019]
   Keywords : LISA; PCB; temperature; passive; aluminum; aluminium;

   Abstract : Gravitational Waves (GWs) are ripples in the curvature of spacetime that propagate as waves at the speed of light while travelling basically undisturbed from the moment of their creation by accelerated masses. GWs provide unique information about astrophysical sources, such as binary systems, allowing their exploration under a wide range of masses, mass ratios and physical states inaccessible otherwise and therefore opening a new window to observe the universe.

4. 3. Sensitivity of Various Qubit Detection Methods in Pr:Y2SiO5

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Author : Vassily Kornienko; [2017]
   Keywords : Rare-earth ion quantum computing; Pr:Y2SiO5; Physics and Astronomy;

   Abstract : The long coherence times of the 4f hyperfine levels of rare-earth-ions gives the possibility to use these as quantum computation devices. Moreover after being doped into a crystal the strong dipole-dipole interaction can be utilized to entangle them. Much work has been done here in Lund to attain as many of the DiVincenzo criteria as possible. READ MORE

5. 4. Ultra-stable frequency transfer using optical fibers
