Abstract
Large interferometric detectors, like VIRGO, are planned to detect gravitational waves, by observing the motions of the suspended mirrors of a Michelson interferometer with kilometric Fabry Perot cavity arms. Due to the large sensitivity needed, the set-up requires a real time monitoring of its mirrors positions, and the analysis of beam shape during the alignment. In this paper, we present the development and the performance of a beam imaging system which uses a CCD camera interfaced to a VME board.
