Abstract
Optical interferometry has started to play a crucial role in the field of star formation. In particular, it offers a unique opportunity to observe protoplanetary disks at a spatial scale where planets may be forming. We present here some of the most recent discoveries in this field putting the emphasis on the progress towards direct imaging of proto-planetary worlds at the astronomical unit scale. In particular we develop our use of the IOTA/IONIC3 interferometer to measure closure phase quantities, a powerful observable to quantify the degree of skewness of the infrared emission at spatial scales corresponding to the internal part of the disk.
