Abstract
The next generation of optical interferometer arrays will require a large number of unit telescopes in the same manner as the VLA if meaningful scientific objectives are to be achieved. Studies based on the five element COAST array show that something like ten to fifteen telescopes are necessary. For such a project to be viable the unit telescopes must be designed from the outset for this task. The basic criteria are as follows: The wavefront quality and stability should be excellent, high optical throughput, autonomous automatic operation, couple efficiently into the beam transport and combination system, plus maintain acceptable unit cost. To achieve these goals a number of novel designs were considered and are described in this paper. Two of the most suitable designs and which had the least technological risk were studied in more detail by Telescope Technology Ltd. and are described in a separate paper.
