The first presentation of the novel interdisciplinary optical remote sensing technique for various ionized diluted media, based on the collisional polarization of the spectoral emission. The book provides a methodology of the impact spectropolarimetic sensing of many solutions to many practical diagnostic problems.

This book gives a complete account of electron momentum spectroscopy to date. It describes in detail the construction of spectrometers and the acquisition and reduction of cross-section data, explaining the quantum theory of the reaction and giving experimental verification.

Polarization Spectroscopy of Ionized Gases describes the physical principles of the technique 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. For researchers interested in the remote sensing of ionized gases.

You’ll learn all the underlying science and how to perform all the latest analytical techniques that plasma polarization spectroscopy (PPS) offers with this new book. The authors report on recent results of laboratory experiments, keeping you current with all the latest developments and applications in the field. There is also a timely discussion centered on instrumentation that is crucial to your ability to perform successful PPS experiments.

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.

Spectropolarimetry is a remote sensing technique that combines both spectral and polarimetric measurements. It is already well-established in the astronomical community as an indispensable tool, permitting characterization of dust clouds and stars, and enhancing observations of planetary bodies. One such noteworthy phenomenon is the opposition effect, wherein a planetary body such as the Moon exhibits a surge in reflected intensity as the phase angle, an angle between the Sun, the Moon, and the observer, decreases to below approximately five degrees. Astronomical and laboratory investigations into the opposition effect reveal that the light of this surge often has a polarized component. The terrestrial remote sensing community is starting to develop an interest in spectropolarimetry. Spectral and polarimetric measurements alone, while useful in their diverse applications, stand to benefit from the added dimensionality that spectropolarimetric measurements provide. Examples of applications that benefit from spectropolarimetric measurement include environmental monitoring, search & rescue, and countering denial and deception techniques. To that end, an improvised imaging spectropolarimeter sensitive in the visible and near-infrared spectrum has been developed by attaching a linear polarization filter to a SOC700 hyperspectral imaging system for use in further development of spectropolarimetric applications. The results of three research objectives are reported upon. First, validation of the operation of the improvised imaging spectropolarimeter and the resulting data calibration and processing techniques, including generating Stokes parameter imagery, is successfully completed. Second, demonstrating that the improvised system is capable of observing the opposition effect in a laboratory setting is also confirmed. Third, the improvised system is used to characterize various materials, including rare earth element oxides and ultra-high performance concrete, in various phase angle geometries, with the intent of determining whether the polarized component of the opposition effect yields sufficient additional information for material detection and identification.
