Spectroscopic methods recently developed for the measurements of electricfields, magnetic fields, and plasma properties in various pulsed-power systemsare described. The methods utilize spectroscopy of visible-UV and X-rayemission-lines and of laser radiation. They allow for non-perturbingmeasurements with relatively high spectral, temporal, and spatial resolutions. Spatial resolution along the line of sight is obtained by locally doping theplasma with various species whose emission is then utilized. A few methodsdeveloped for doping solid and gaseous materials are described. Results for anion diode, nanosecond and microsecond Plasma Switches, and a pinch system are presented.
