Scientific paper

The principles of optical aperture synthesis (OAS), which can yield images of much higher resolution than current ground observations, are essentially those of radio astronomy, and may be used in either space- or ground-based studies of the stellar envelopes around Be stars, the internal dynamics of active galaxies, etc. An account is presently given of possible OAS instrument configurations; it is shown that a large field of view can be achieved, so that the instrument may be calibrated on bright stars during the observation of faint sources. Mission concepts for a 'monostructure' OAS instrument of about 30-m size are examined.
