astronomical interferometer造句

• The intensity interferometer measures interferometric visibilities like all other astronomical interferometers.
• They are part of a project to build an astronomical interferometer.
• This array of holes acts as a miniature astronomical interferometer.
• Astronomical interferometers come in two types direct detection and heterodyne.
• Aperture synthesis can be used to perform high-resolution imaging using astronomical interferometers.
• NPOI is a successful astronomical interferometer of the venerable and proven Michelson Interferometer design.
• Astronomical interferometers are widely used in optical astronomy, infrared astronomy, submillimetre astronomy and radio astronomy.
• The "'Michelson stellar interferometer "'is one of the earliest astronomical interferometers built and used.
• Radio wavelengths are much longer than optical wavelengths, and the observing stations in radio astronomical interferometers are correspondingly further apart.
• He later moved on to use astronomical interferometers in the measurement of stellar diameters and in measuring the separations of binary stars.
• In astronomy, the most common use of such an astronomical interferometer is to determine the apparent angular diameter of a radio source or star.
• The NPOI is an astronomical interferometer laid out in a three-arm " Y " configuration, with each equally-spaced arm measuring long.
• The most recent design envisaged three free-flying space telescopes, each three to four metres in diameter, flying in formation as an astronomical interferometer.
• APEX is a precursor of ALMA ( the Atacama Large Millimeter Array ), an astronomical interferometer which ESO and its international partners is building on the Chajnantor plateau.
• This technique is the basis for astronomical interferometer arrays, which can make measurements of very small astronomical objects if the telescopes are spread out over a wide area.
• ALMA is an astronomical interferometer of innovative design, initially composed of 66 high-precision antennas and operating at wavelengths of 0.3 to 3.6 mm.
• An astronomical interferometer achieves high-resolution observations using the technique of aperture synthesis, mixing signals from a cluster of comparatively small telescopes rather than a single very expensive monolithic telescope.
• In 1919 the 100 inch Hooker telescope was equipped with a special attachment, a 20-foot optical astronomical interferometer developed by Albert A . Michelson and Francis G . Pease.
• One simple layout of an astronomical interferometer is a parabolic arrangement of mirror pieces, giving a partially complete reflecting telescope but with a " sparse " or " dilute " aperture.
• An astronomical interferometer consists of two or more separate telescopes that combine their signals, offering a resolution equivalent to that of a telescope of diameter equal to the largest separation between its individual elements.
