First images on the sky from a hyper telescope ⋆
We show star images obtained with a miniature “densified pupil imaging interferometer” also called a hyper-telescope. The formation of such images violates a “golden rule of imaging interferometers” which appeared to forbid the use of interferometric arrangements differing from a Fizeau interferometer. These produce useless images when the sub-apertures spacing is much wider than their size, ow...
متن کاملThe Oxford SWIFT Spectrograph: first commissioning and on-sky results
The Oxford SWIFT spectrograph, an I & z band (6500–10500 Å) integral field spectrograph, is designed to operate as a facility instrument at the 200 inch Hale Telescope on Palomar Mountain, in conjunction with the Palomar laser guide star adaptive optics system PALAO (and its upgrade to PALM3000). SWIFT provides spectra at R( / )~4000 of a contiguous two-dimensional field, 44 89 spatial pixels (...
متن کاملFirst On-Sky Fringes with an Up-Conversion Interferometer Tested on a Telescope Array.
The Astronomical Light Optical Hybrid Analysis project investigates the combined use of a telescope array interferometer and nonlinear optics to propose a new generation of instruments dedicated to high-resolution imaging for infrared astronomy. The nonlinear process of optical frequency conversion transfers the astronomical light to a shorter wavelength domain. Here, we report on the first fri...
متن کاملFrom first conception to first demonstration
The early history of applying electronic computers to the task of translating natural languages is chronicled, from the first suggestions by Warren Weaver in March 1947 to the first demonstration of a working, if limited, program in January 1954.
