Electromagnetically induced transparency of Rydberg atoms presents the unique possibility to image individual Rydberg atoms immersed in a dense atomic gas and to study their spatial correlations. In our recent proposal [1] the level shifts induced by the Rydberg atoms to the surrounding gas are utilized to provide sensitive, single-shot absorption images of individual Rydberg atoms.

To experimentally realize this idea we require quasi-1D or 2D trapping geometries and a high resolution imaging system capable of resolving single Rydberg blockade spheres. Therefore we designed and implemented a diffraction limited imaging system taking maximum advantage of the present experimental setup. Additionally we optimized critical experimental parameters including atomic density and exposure time to achieve the highest possible signal-to-noise ratio and spatial resolution. We will present our experimental progress towards imaging single Rydberg atoms.
