[en] The present notes refer to a 3-hour lecture delivered on 27 September 2017 in Roscoff during the 2017 Evry Schatzman School. It concerns a general introduction to optical/IR interferometry, including a brief history, a presenta- tion of the basic principles, some important theorems and relevant applications. The layout of these lecture notes is as follows. After a short introduction, we proceed with some reminders concerning the representation of a field of elec- tromagnetic radiation. We then present a short history of interferometry, from the first experiment of Fizeau and Stefan to modern optical interferometers. We then discuss the notions of light coherence, including the theorem of Zernicke- van Cittert and describe the principle of interferometry using two telescopes. We present some examples of modern interferometers and typical results ob- tained with these. Finally, we address three important theorems: the fundamen- tal theorem, the convolution theorem and the Wiener-Khinchin theorem which enable to get a better insight into the field of optical/IR interferometry.
