Interferometric imaging of the solar surface which can produce diffraction limited pictures with ground based telescopes, despite the deleterious effects of the Earth's atmosphere is considered. Speckle imaging in broad bands, successful in broad spectral bands for a number of years, is discussed. Recent advances in the methodology show that speckle techniques can succeed at a spectral resolution good enough to permit meaningful spectroscopic observations. Some results in speckle imaging are presented. Fizeau stellar interferometry applied to solar structure is investigated, and its potential and limitations are demonstrated.
