INFORMATION GAIN IN MULTI-PIXEL ACQUISITION GHOST IMAGING TECHNIQUES (IMAGIT)
This webpage concerns the Marie Skłodowska-Curie individual fellowship project, Grant agreement ID: 706410.
The project is conducted by Dr. Paul-Antoine Moreau in the Optics group at the University of Glasgow.
OBJECTIVES
2017-2019
Optical intensity measurements usually recover only partial information of the wave and of the media that has been gone through since phase information is lost. Interferometric imaging techniques allows us to recover the phase information but are often unstable and hard to implement due to mechanical vibrations and media fluctuations. On the other hand, in recent years an imaging technique called Ghost Imaging has attracted increasing interest through its ability to recover apparently hidden information on the spatial structure of a light beam.
We propose different methods that take advantage of a spatially resolved detection in the context of Ghost Imaging, to achieve better performances than conventional imaging as well as usual Ghost Imaging.
