1. High contrast imaging through turbid media using Fourier filtering and phase retrieval algorithm
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : 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

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 institutionenAbstract : 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.

3. High Contrast Imaging Through Scattering Media Using Structured Illumination Fourier Filtering
University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenAbstract : 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
