  The Interferometric studies of novae in the optical and near-infrared is a
nascent but fast emerging field which has begun to provide new and invaluable
insights into the nova phenomenon. This is particularly so in the early stages
of the eruption when all the relevant physical phenomena are on the scale of
milli-arcseconds and thus are amenable to be studied only by interferometric
techniques. In this review the instruments and arrays involved in this domain
of work are briefly described, followed by a description of the major results
obtained so far. A discussion is made of the physical aspects, where the
application of interferometric techniques, can bring the most valuable
information. Finally, prospects for the near future are discussed.
