Aperture synthesisAperture synthesis or synthesis imaging is a type of interferometry that mixes signals from a collection of telescopes to produce images having the same angular resolution as an instrument the size of the entire collection. At each separation and orientation, the lobe-pattern of the interferometer produces an output which is one component of the Fourier transform of the spatial distribution of the brightness of the observed object. The image (or "map") of the source is produced from these measurements.
Chief operating officerA chief operating officer or chief operations officer (COO) is an executive who manages the personnel, resources, logistics, and daily operations of an organization. COOs are usually second-in-command immediately after the CEO, and reports directly to them and acts on their behalf in their absence. A COO is usually voted in by shareholders or appointed by the board of directors.
