Aperture synthesis is a technique used in radio astronomy to combine data from multiple telescopes to create a high-resolution image of a celestial object. This technique allows astronomers to see details that would be impossible to observe with a single telescope.
Definitions
Aperture synthesis is a method of combining data from multiple telescopes to create a high-resolution image of a celestial object. It involves taking measurements of the same object from different positions and then using mathematical algorithms to combine the data into a single image.
Origin
The technique of aperture synthesis was first proposed by Martin Ryle and his colleagues in the 1950s. Ryle was a pioneer in radio astronomy and was awarded the Nobel Prize in Physics in 1974 for his contributions to the development of aperture synthesis.
Meaning in different dictionaries
According to the Oxford English Dictionary, aperture synthesis is “a technique used in radio astronomy to combine data from multiple telescopes to create a high-resolution image of a celestial object.”
The Merriam-Webster Dictionary defines aperture synthesis as “a method of combining the signals from several radio telescopes to produce a single image of a celestial object that has a resolution equivalent to that of a much larger telescope.”
Associations
Aperture synthesis is closely associated with radio astronomy and is used to study a wide range of celestial objects, including galaxies, stars, and planets. It is also used in other fields, such as medical imaging and radar.
Synonyms
Some synonyms of aperture synthesis include interferometry, radio interferometry, and synthesis imaging.
Antonyms
There are no direct antonyms of aperture synthesis, as it is a specific technique used in radio astronomy.
The same root words
The word “aperture” refers to the opening through which light enters a camera or telescope, while “synthesis” refers to the combination of different elements to create something new. Together, these words describe the process of combining data from multiple telescopes to create a high-resolution image.
