Experimental results from a multiple telescope imaging array

A nine telescope imaging phased array is being demonstrated at the Lockheed-Martin Advanced Technology Center in Pale Alto. The array consists of nine afocal telescopes arranged in a y-formation that are combined to a common focus in a Fizeau interferometer configuration. We have demonstrated diffraction limited performance over a 150 micro-radian field of view with broadband (500 to 800 nm) illumination.
