FAQ
Frequently Asked Questions
Primarily, yes. Its foundational principles are in radio interferometry. A related but distinct concept, synthetic aperture, is used in radar (SAR).
Aperture synthesis is a specific application and result of interferometry. Interferometry is the broader method of combining waves; aperture synthesis uses interferometric data to computationally construct a high-resolution image.
It is exceedingly difficult with optical light due to atmospheric turbulence, but the principle is the same in optical interferometry, a cutting-edge and complex field.
The technique was pioneered in the 1950s by Sir Martin Ryle and his team at Cambridge, for which Ryle received a Nobel Prize.
a technique in radio astronomy where signals from multiple radio telescopes are combined to create a single image with a resolution equivalent to that of a telescope as large as the maximum distance between the individual dishes.
