1. 1. High contrast imaging through turbid media using Fourier filtering and phase retrieval algorithm

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Sam Taylor; [2022]
   Keywords : ;

   Abstract : Fourier filtering is a powerful technique to improve the contrast when imaging through turbid media. However, the trade-off between contrast and spatial resolution is a long-standing issue that limits the Fourier filtering technique to low spatial resolution requirements. READ MORE

3. 2. Optical FRAME: Investigating the effects of filtering the optical Fourier domain to be used as a new approach for FRAME

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

   Author : Sam Taylor; [2020]
   Keywords : Fourier Optics FRAME Ultra-fast imaging; Physics and Astronomy;

   Abstract : Many important scientific phenomena require ultra-fast imaging to understand and investigate the characteristics of the event. Current methods of ultra-fast imaging that can obtain femtosecond time resolution rely on repeatable events or limiting the techniques versatility by completely remove the use of a dimension e.g. colour.

4. 3. High Contrast Imaging Through Scattering Media Using Structured Illumination Fourier Filtering

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

   Author : David Frantz; [2017]
   Keywords : scattering media; Structured Illumination; optical Fourier filtering; Modulation Transfer Function; Monte Carlo simulation; Technology and Engineering;

   Abstract : In imaging, obtaining high contrast is of great importance. When imaging through scattering media, optical filtering techniques are used to filter out multiple light scattering which causes loss of contrast. READ MORE
