| Summary: | In conventional imaging systems, the emitted light from a source interacts with an object and the
intensity of the transmitted or reflected light is captured by a spatially resolving detector. In this thesis,
a fundamentally different imaging principle has been studied, known as ghost imaging (GI). In contrast
to conventional imaging, GI exploits the intensity correlations of light to form an image of an object. A
ghost image is obtained by measuring the total intensity of the transmitted or reflected light of an
illuminated object and the spatially resolved intensity of a highly-correlated reference beam which itself
has never interacted with the object. The information of both intensities alone is not enough to form an
image of the object. However, image reconstruction can be achieved by correlating the two intensities.
Intriguingly, the spatial resolution of the ghost image is provided by the non-interacting reference beam.
The work presented in this thesis joins into the continuous strive for making GI applicable to real-world
sensing and imaging fields. The title: Classical ghost imaging with opto-electronic emitters, reflects one of
the approaches to this objective. The second approach is what rather sets this thesis apart from other
ongoing work on GI. Instead of utilizing state-of-the-art detection systems, novel GI configurations are
developed. |
