Abstract

The V.L.T. mirror characteristics : - a huge size, - a great flexibility, calls for an improvement of conventional techniques previously used for polishing, figuring and testing. These mirrors must be free of : - high frequency defects, - non axisymmetric defects not correctable by the active optic system. Fortunately, thanks to their active shape control, a given amount of low frequency defects can be tolerated.
