3. 2. Investigation of phase conjugation for medical imaging

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

   Author : Ivan Sytcevich; [2017]
   Keywords : Phase conjugation; Ultrasound Optical Tomography; Rare-Earth-Doped Crystals.; Physics and Astronomy;

   Abstract : With the development of extremely precise spectral filters based on spectral hole burning and slow light effects, the idea of their implementation in an Ultrasound Optical Tomography (UOT) medical imaging technique arose. Simulations have shown that the resulting Contrast-to-Noise (CNR) ratio is fairly good at depths up to 5 cm but decreases dramatically when probing deeper in tissue. READ MORE

4. 3. Development of a temperature control system for spectroscopic measurements with rare-earth doped crystals

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

   Author : Sijia Huang; [2014]
   Keywords : Physics and Astronomy;

   Abstract : This thesis describes the development of a temperature control system for optical spectroscopy experiments with rare-earth doped samples. Low temperature emission spectra were afterwards recorded for a series for Eu3+ singly doped and Ce3+, Eu3+ codoped Y2SiO5 samples. The analysis and assignment of the different energy transitions is presented. READ MORE

5. 4. Retrieval of cavity embedded absorption spectrum for quantum memory applications

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

   Author : Robin Ekelund; [2014]
   Keywords : Quantum memory; Absorption Spectrum; Cavity; Physics and Astronomy;

   Abstract : Inom fältet kvantinformation behandlar man information med hjälp av så kallade kvantmekaniska system, vilket tillför både möjligheter och svårigheter i reella tillämpningar. Ett fundamentalt begrepp är den så kallade kvantbiten, eller qubit som den brukar omnämnas i engelsk litteratur, vilken är den grundläggande komponenten i vilken kvantinformation hanteras, som en direkt analog till biten i en klassisk dator.
