T. Fujimoto graduated from Kyoto University in 1964, finished his PhD. in 1969. He has been professor of Kyoto University from 1982 to 2005. He published "Plasma Spectroscopy" from Oxford University Press in 2004.

A. Iwamae graduated from Kyoto University in 1992, finished his Ph.D. in 1997. He has been Lecturer of Kyoto University from 1999. He has been working on PPS experiments of various plasmas.

Plasma Polarization Spectroscopy (PPS) is now becoming a standard diagnostic technique for working with laboratory plasmas. This new area needs a comprehensive framework, both experimental and theoretical. This book reviews the historical development of PPS, develops a general theoretical formulation to deal with this phenomenon, along with an overview of relevant cross sections, and reports on laboratory experiments so far performed. It also includes various facets that are interesting from this standpoint, e.g. X-ray lasers and effects of microwave irradiation. It also offers a timely discussion of instrumentation that is quite important in a practical PPS experiment.
