Interferometry in the visible and in the IR now provides milliarc-second spatial resolution and thus can be used for studying the circumstellar environment of hot star disks. After a brief introduction on the interferometric technique we will illustrate how the modulus and the phase of the visibility can be used to constrain the physics of hot star disks (Be, B[e]) and stellar surfaces studies through recent results from the GI2T, Keck, MkIII, NPOI, VLA and VLTI interferometers.
