We report electromagnetically induced transparency for the D1 and D2 lines in 6 Li in both a vapour cell and an atomic beam. Electromagnetically induced transparency is created using co-propagating mutually coherent laser beams with a frequency difference equal to the hyperfine ground state splitting of 228.2 MHz. The effects of various optical polarization configurations and applied magnetic f...

Difference EIT reconstructs a signal generated by conductivity contrasting regions. We explore the effect that, for large contrasts, conductive regions produce a greater signal than non-conductive ones, and this difference is determined by the region shape.

There has been an increasing interest in all-optical analogues of electromagnetically induced transparency and Autler-Townes splitting. Despite the differences in their underlying physics, both electromagnetically induced transparency and Autler-Townes splitting are quantified by a transparency window in the absorption or transmission spectrum, which often leads to a confusion about its origin....

The growing interest in the use of autonomous systems for both military and commercial applications has been accompanied by a concomitant increase in research involving human-agent interaction. Transparency has been investigated as one factor that could improve human trust in, and appropriate reliance on, autonomous systems. This report provides a review of studies that have examined how the tr...

Does enhanced transparency, through the Internet, boost the legitimacy of the EU? In this paper we present a critical perspective on the assumptions underlying the relation between transparency and legitimacy. We reconstruct three assumptions from EU policy documents – transparency strengthens input legitimacy, output legitimacy and social legitimacy – and then highlight several weaknesses. We ...

Perceptual transparency requires local same-polarity X-junctions, which can also be generated by temporal integration under natural dynamic conditions. In this study, segmentation performance and target appearance were measured for a uniform gray target embedded in a random-dot frame presented with a temporally adjacent mask. Although static cues for both segmentation and transparency were unav...
