Degree Angular Scale Interferometer
Encyclopedia
The Degree Angular Scale Interferometer (DASI) was a telescope located in Antarctica. It was a 13-element interferometer operating between 26 and 36 GHz in ten bands. The instrument is similar in design to the Cosmic Background Imager
and the Very Small Array
. In 2002 the DASI team reported the first detection of polarization anisotropies in the Cosmic Microwave Background.

Very Small Array
The Very Small Array is a 14-element interferometric radio telescope operating between 26 and 36 GHz that is used to study the cosmic microwave background radiation. It is a collaboration between the University of Cambridge, University of Manchester and the Instituto de Astrofisica de Canarias...
