The participants will take action to ensure that Europe will play a leading role in the development of optical interferometry over the next decade and to enable European astronomers to fully exploit the scientific potential of existing and planned large facilities. The near-term scientific productivity of interferometers is limited mainly by: (1) the inherent limitations of the existing focal-plane instrumentation and the difficulties of phasing and co-phasing the elements of interferometric arrays, (2) the lack of adequate algorithms and tools for the analysis and interpretation of the data, (3) limitations of component technologies and modelling tools. The participants will address areas (1) and (2) through the coordinated development of advanced analysis software, and targeted initiatives to further the design of next-generation focal-plane instrumentation and fringe tracking devices.
