In this paper we report on space and time resolved spectroscopic measurements on Masuda type surface DBD fed by N2. In our configuration the discharge presents some defects that lead to the formation of some bright spot inside a regular discharge region formed by streamers. We have carried out an optical investigation of both the regular discharge region and the bright spot one with the aim to stress the aspects of photo emission contribution in the dynamics of microdischarge. We have carried out also spectroscopic space and time resolved investigation of discharge emission when UV photons by a pulsed laser interact with the dielectric surface of DBD. There is a similarity between the time evolution of emission from bright spots and that produced by laser photons.
