Abstract
Extracted from the Berger-Fringant catalog of faint blue objects, PB 6378 and PB 9261 are two systems of interacting galaxies with prominent starbursts. Photometry of these systems was done by electronography; bidimensional spectroscopic data with spatial resolution of 1 arcsec or better were obtained by using a fiber optics spectrograph. Spectra integrated over the different components are then obtained, as well as velocity fields and intensity maps in the continuum and in the emission lines. This makes it possible to estimate the physical conditions in these starburst systems. The possibility of extending the method to similar but more distant objects is discussed
