The ESO differential image motion monitor
Abstract
This paper describes the ESO differential image-motion monitor and reviews the theory of differential image motion measurements. It is shown that this small transportable image-motion monitor, which is able to operate in the open air, can yield quantitative estimates of the image quality produced by a large telescope situated at the same location. Several copies of this instrument are being used for the European Very Large Telescope site testing campaign, in search of the best possible location for this telescope.
