Scientific paper

It is now twenty years since the pioneering work of Antoine Labeyrie gave the technique of stellar speckle interferometry to the astronomical community. Subsequently, the field has exploded with many new insights, ideas and innovations. This paper reflects upon and discusses these developments. In particular, the extremely powerful speckle imaging techniques such as triple correlation analysis or speckle masking are reviewed. Image reconstruction algorithm developments are considered. The recent developments in the area of imaging using pupil masking, aperture synthesis and phase-closure techniques are also discussed.
