Optical Long-Baseline Interferometry: Technological Overview and Science Highlights

In order to achieve the highest spatial resolutions, long-baseline interferometry is the method of choice. In the optical and infrared domain, this observing method is very different to radio and sub-mm interferometry since direct recombination of the light from multiple telescopes is required. In this talk, I will give a brief overview of the technical requirements for optical long-baseline interferometry, introduce the relevant observatories / instruments where this technique is used and review scientific highlights from the characterisation of exoplanets to the measurement of super-massive black holes and their surroundings.
