We report on recent developments in positronium work in the frame of antihydrogen production through charge exchange in the AEgIS collaboration [1] . In particular, we present a new technique based on spatially imaging a cloud of positronium by collecting the positrons emitted by photoionization. This background free diagnostic proves to be highly efficient and opens up new opportunities for spectroscopy on antimatter, control and laser manipulation of positronium clouds as well as Doppler
