A network of several radio telescopes wired together
Wiki User
∙ 7y ago
A radio interferometer is a scientific instrument used to observe and study radio waves emitted by celestial objects such as stars, galaxies, and quasars. It consists of multiple radio antennas or dishes that are spread out over a large area and work together to create a combined signal. By combining the signals from different antennas, a radio interferometer can create high-resolution images and precise measurements of radio sources in the universe.

Why astronomers use an interferometer?
Your eyes and brain form an interferometer, allowing for 3D imaging.
Why have you used non-electrolytic liquid in ultrasonic interferometer experiment?
if we know then why we use it
Why would radio astronomers build identical radio telescopes in different places around the world?
There are at least two reasons why identical radio telescopes may be built. A mundane reason would to save money by reusing the same design. But the reason why most identical systems are built (not to say that saving money by reusing the design isn't still a factor in these cases) is to construct a "very long baseline interferometer", a type of multiple telescope system that uses properties of electromagnetic radiation (wave interference) to simulate telescopes with much larger apertures. This method attains the angular resolution of the larger telescope, but not the signal sensitivity.
What is the difference between IR and FT IR instruments?
A standard IR runs a single spectrum. An FT-IR uses an interferometer and makes several scans and then uses Fourier Transforms to convert the interferogram into an infrared spectrum.
Do gravitational waves exist?
Most physicists are convinced they do exist. The Laser Interferometer Gravity Wave Observatories (LIGO) were built to detect gravity waves from colliding neutron stars, supernova, and other space-time fabric disturbing events.
When several radio telescopes are wired together the resulting network is call?
Interferometer.
What has the author Robert M Hjellming written?
Robert M. Hjellming has written: 'An introduction to the NRAO interferometer' -- subject(s): Radio interferometers
Why astronomers use an interferometer?

When was Plateau de Bure Interferometer created?
Plateau de Bure Interferometer was created in 1988.
What is the interferometer used for?
It allows two or more small telescopes to achieve the angular resolution of a much larger telescope. This instrument is credited to Albert A. Michaelson.
What is the purpose of compensating plate in michelson interferometer?
a compensating plate is used in michelson interferometer to compensate the additional path difference of ray 1
What did Albert Michelson do?
He is the inventorof the Michelson interferometer.
What are some applications of the Michelson Interferometer?
The Michelson Interferometer is used to create an interference pattern by splitting a beam of light into two paths. This device has several important scientific applications for experimentation.
When two or more telescopes are wired together what is the resulting network?
Interferometer
What is the principle used in ultrasonic interferometer?
Inverse piezo-electric effect.
Why circular fringes are obtained in michelson interferometer?
The mirrors are perfectly perpendicular
Explain how ultrasonic waves can be produced in the laboratory?
using ultrasonic interferometer
