Scientific paper

The Very Large Telescope (VLT) program is developing an array of four 8-m aperture telescopes able to operate either individually or in combination. The technology development efforts of the VLT program encompass thin, zero-expansion glass mirrors, metal mirrors, actively supported deformable mirrors, replication of optical surfaces, wideband optical coatings, large brushless torque motors, and adaptive optics systems. An inflatable dome structure is envisioned as the housing for each of the four telescopes. Wavefront errors will be determined in quasi-real time, on the basis of an analysis of the image of a reference star.
