Abstract

The VLTI Delay Line verification program has been performed in the first quarter of the year 2000. This paper will present results from the measurements done at Fokker Space premises, supported by results from Matlab simulations. Key requirements are addressed, except for those which deal with the opto-mechanical verification. Jitter on the mechanical velocity and the OPD, as well as pupil stability and heat dissipation in the tunnel, have been driving requirements for the design and construction of the Delay Lines. The results which are presented below will demonstrate that these requirements are met with the `Two-Stage' concept chosen for the control of the commanded optical path trajectory.
