Interferometry meets the third and fourth dimensions in galaxies

open access: yes, 2014
Radio astronomy began with one array (Jansky's) and one paraboloid of revolution (Reber's) as collecting areas and has now reached the point where a large number of facilities are arrays of paraboloids, each of which would have looked enormous to Reber ...

Technology challenges for space interferometry: the option of mid-infrared integrated optics

open access: yes, 2007
Nulling interferometry is a technique providing high angular resolution which is the core of the space missions Darwin and the Terrestrail Planet Finder. The first objective is to reach a deep degree of starlight cancelation in the range 6 -- 20 microns,

Surface figure measurements of radio telescopes with a shearing interferometer [PDF]

open access: yes, 1991
A new technique for determining the surface figure of large submillimeter wavelength telescopes is presented, which is based on measuring the telescope’s focal plane diffraction pattern with a shearing interferometer.

Computing extinction maps of star nulling interferometers

open access: yes, 2008
Herein is discussed the performance of spaceborne nulling interferometers searching for extra-solar planets, in terms of their extinction maps projected on-sky.

Inner disk regions revealed by infrared interferometry

open access: yes, 2007
I review the results obtained by long-baseline interferometry at infrared wavelengths on the innermost regions around young stars. These observations directly probe the location of the dust and gas in the disks.

Bispectral technique for reconstruction the astronomical images with an intensity interferometer

open access: yes, 2008
An extension may be proposed to the intensity interferometer of Hanbury Brown and Twiss to provide the Fourier phase measurement by the use of third-order intensity correlations. It is well known that interferometric reconstruction of astronomical images can be obtained from second-order correlations only when a priory information is used about the ...
