Abstract: Speckle interferometry has proven to be a powerful tool to detect sub-arcsecond binaries and measure their parameters. However, due to the sophisticated methods required to reduce the data, not very many astronomers know how to use it. In this contribution, I describe the basic methods used to reconstruct modulus and phase of the Fourier transformed high-resolution image from speckle data. I will also show some example data of binary stars, and demonstrate why the simple structure of the Fourier transform of binary star images makes them ideal targets for speckle-interferometry, allowing to detect binaries with separations at and sometimes even below the diffraction limit of the telescope.
