The scanning Fabry-Perot interferometer is a powerful tool for 3D spectroscopic study of the emission-line kinematics of extended objects. I briefly review the opportunities of this technique on the last decade observations at the SAO RAS 6-m telescope. The results concerning different Galactic and extragalactic objects are considered: Herbig-Haro flows, polar and collisional rings galaxies, expanding bubbles in dwarf galaxies, hypernova remnantt, etc.
