Scientific paper

An optical stellar interferometer is described by means of which images may be obtained using the technique of aperture synthesis. It consists of a number of mirrors and a single detector located at their common focus. Each mirror is endowed with a device to introduce a variable time delay in the optical path. By a suitable modulation of these time delays the cross correlations between the electric fields for each pair of mirrors can be deduced from different frequency components of the detector signal, these correlations being proportional to the Fourier transform of the intensity. It is possible to correct for 'seeing' and instrumental errors.
