Abstract

We discuss a four element non-redundant array telescope-interferometer for ground use. The elements are 8 meter mirrors, and the maximum array spacing and two element spacing are 75m and 108m respectively. The array may be used as three separate telescopes, one 11.3m and two 8m for work not requiring highest angular resolution. We discuss the problems of making speckle measures to high enough precision for synthetic images to be produced. We conclude by showing that the high resolution presents opportunities to make types of observation that are neither possible with VLBA nor NNTT.
