Here is slides and video for a talk "Adaptive Optics Imaging of Extosolar Planets" from 2015.

Especially the review of history of the study of exoplanets is amusing. When only our solar system was known, everyone believed in the theory of "inner rocky planet region, outer gas giant planet region". When astronomers finally started to have instruments to actually detect planets in other solar systems in the mid-1990s, almost none of the detected exoplanets fit the theory (slides 5-8).
