This text describes basic and applied spectroscopic techniques for the study of physical processes in high frequency, electrodeless discharge lamps. Special attention is given to the construction and optimization of these lamps, a popular source of line spectra and an important tool in ultraprecise optical engineering. Highlights include discussions of high precision measurements of gas pressures, and spectral source lifespan.

A presentation of the novel interdisciplinary optical remote sensing technique for various ionized diluted media, based on collisional polarization of spectoral emissions. The work aims to provide a methadology for impact spectropolarimetic sensing suitable for solving many practical diagnostic problems. Major sections of the work describe the quantum mechanical theory behind collisional polarization of atomic particles, the effects of original impact polarization in ionized media, methodology and practical techniques for observation of solar flares as an illustrative astrophysical example, results of spectropolarimetric sensing based on ground-based observational data and estimates of the energy transported by fast particles to the upper chromosphere of the sun.

"Demonstrational Optics" presents a didactical approach to the study of optics. Emphasizing the importance of elaborate new experimental demonstrations, pictorial illustrations, computer simulations and models of optical phenomena in order to ensure a deeper understanding of the general and statistical optics. It includes problems focused on the pragmatic needs of students, secondary school teachers, university professors and optical engineers. This volume aims to present improved teaching methods and practical explanations of optical phenomena. An important feature is the inclusion of elaborate pictorial approach to explaining optical phenomena in parallel to a general mathematical description. The modern approach developed here is also used to illustrate many basic phenomena, complimenting the existing literature. The volume contains a compendium of optical experiments for university, college and senior-school physics teachers. Experiments and modern computer simulations are described within the volume in sufficient detail to allow successful reproduction in a classroom or lecture theatre.

Demonstrational Optics presents a new didactical approach to the study of optics. Emphasizing the importance of elaborate new experimental demonstrations, pictorial illustrations, computer simulations and models of optical phenomena in order to ensure a deeper understanding of wave and geometric optics. It includes problems focused on the pragmatic needs of students, secondary school teachers, university professors and optical engineers. Part 2, Coherent and Statistical Optics, contains chapters on interference, diffraction, Fourier optics, light quanta, thermal radiation (Shot noise and Gaussian light), Correlation of light fields and Correlation of light intensities. A substantial part of this volume is devoted to thermal radiation and its properties, especially with partial coherence. A detailed treatment of the photo-effect with respect to statistical properties leads to the basics of statistical optics. To illustrate the phenomena covered by this volume, a large number of demonstration experiments are described and discussed. In the chapters devoted to statistical phenomena computer simulations are described, the code of all relevant programs being included.

This work describes the physical principles of the technique of polarization spectroscopy and its applications to remote sensing. Transport phenomena and local anisotropies can be studied. The theoretical part of the book considers the basic phenomena of the ordering of the velocities of fast exciting charged particles. The polarization of the outer electron shells of excited atoms or molecules is described, and a variety of effects are examined in detail. An integral equation is derived which gives the intensity and polarization of emitted lines. Methods for solving the equation are analyzed. Universal spectropolarimetric remote sensing has been applied to low-pressure gas discharges in the laboratory and to non-thermal processes in the solar atmosphere. The book is designed for researchers interested in the remote sensing of ionized gases.

A uniquely practical book, this monograph is the first to describe basic and applied spectroscopic techniques for the study of physical processes in high frequency, electrodeless discharge lamps. Special attention is given to the construction and optimization of these lamps, a popular source of line spectra and an important tool in ultraprecise optical engineering. Highlights include discussions of: high precision measurements of gas pressures spectral source lifespan and more.

This book arises from the significant quantity of original results in the field of impact spectropolarimetry, mainly for solar flare studies, and the evident potential applications of this technique to environmental physics, astrophysics, and hot plasma. This is a practically oriented book, describing theoretical fundamentals and implementation of this new interdisciplinary remote sensing technique. A basic phenomenon for impact spectropolarimetric sensing is the polarization ofthe electron shells of an ensemble of free atomic particles (atoms, ions, molecules) due to collisional interaction. Slow collisions in the presence of internal anisotropies in the relative velocity space inside any ionized medium, as well as bombardment of a diluted gas by fast precipitating light projectiles, are analyzed in detail as principal impact polarization mechanisms. Impact spectro­ polarimetric sensing incorporates state-of-the-art theoretical methods of colli­ sional physics in combination with reliable polarimetric measurements. This technique is illustrated by the new quantitative sensing of energy transport to the upper region of the chromosphere during solar flares, making use of ground­ based solar spectropolarimetric observations. Apart from general astrophysical and solar-terrestrial significance, a solar flare, the brightest nonthermal phenomenon, is a good candidate for the demonstration of new opportunities of impact spectropolarimetry. New astrophysical achievements of quantitative spectropolarimetry are particularly considered in this book. The theoretical part presents a quantum mechanical description of impact polarization and the spectropolarimetric manifestations for different energies of the colliding partners.
