  • Optical Image Formation and Processing

    • 1 Edición
    • M Francon
    • Inglés
    Optical Image Formation and Processing describes modern physical optics, particularly concerning interference, diffraction, and a simplified theory of partial coherence. The book also discusses polarization, with emphasis on interference phenomena on polarized light. An image is formed in terms of the filtering of spatial frequencies, filtering that is due to transfer function. The text explains holography—a reconstruction of the image of an object beginning from the diffraction patterns produced by the object. A computer can also create artificial variations from the photographic plate which records the hologram, and can synthesize the hologram. The book cites an example of the synthesis of a hologram by a computer using the principle of binary holograms. The text also reviews some experiments dealing with the properties of lasers associated with temporal coherence and power. The book explains that lasers can carry large amounts of information due to their very high frequencies in the order of 300, 000 gigahertz, and recommends the use of optical fibers as the transmission medium instead of using open air. This book can prove useful for technicians, students, and professor connected with optical physics.

    • Peter R. Fontana
    • Inglés
    Atomic Radiative Processes provides a unified treatment of the theory of atomic radiative processes. Fourier transforms are used to obtain solutions of time-dependent Schrödinger equations, and coupled differential equations are transformed to coupled linear equations that in most cases can be readily solved. This book consists of nine chapters and begins with an overview of some of the properties of the classical field and its interaction with particles, focusing on those aspects needed for a better understanding of quantum theory. The Hamiltonian formalism is used to quantize the field, and the density of states of the radiation field is considered. The following chapters focus on a few Fourier transform techniques and their application to such areas as coherence properties of the field and amplitude and intensity correlations; the theory of angular momentum; the properties of irreducible tensors; quantization of the radiation field; and photon states. The interaction of a two-level atom with single modes of the radiation field is also discussed, along with spontaneous emission and decay processes; the evolution of coupled atomic states; the frequency distribution of emitted radiation; and radiative excitation and fluorescence.

  • Nonlinear Optics

    Fundamentals, Materials and Devices
    • 1 Edición
    • S. Miyata
    • Inglés
    The field of nonlinear optics developed gradually with the invention of lasers. After the discovery of second-harmonic generation in quartz, many other interesting nonlinear optical processes were rapidly discovered. Simultaneously theoretical programmes for the understanding of nonlinear optical phenomena were stimulated in accordance to develop structure-property relationships. In the beginning, research advances were made on inorganic ferroelectric materials followed by semiconductors. In the 1970's, the importance of organic materials was realised because of their nonlinear optical responses, fast optical response, high laser damage thresholds, architectural flexibility, and ease of fabrication. At present materials can be classified into three categories - inorganic ferroelectrics, semiconductors, and organic materials. Advances have also been made in quantum chemistry approaches to investigate nonlinear optical susceptibilities and in the development of novel nonlinear optical devices. Generally, inorganic and organic nonlinear optical materials and their related optical processes are reported in separate meetings. This book collects for the first time papers covering the recent developments and areas of present research in the field of nonlinear optical materials.

    • K.N. Rao
    • Inglés
    Wavelength Standards in the Infrared is a compilation of wavelength standards suitable for use with high-resolution infrared spectrographs, including both emission and absorption standards. The book presents atomic line emission standards of argon, krypton, neon, and xenon. These atomic line emission standards are from the deliberations of Commission 14 of the International Astronomical Union, which is the recognized authority for such standards. The text also explains the techniques employed in determining spectral positions in the infrared. One of the techniques used includes the grating constant method of determining spectral positions which measures the angular rotation of the grating. Another technique used is the modern gratings and high resolution infrared spectra which has made it possible to obtain narrower spectral lines. Computers can expedite the processing of observed data. Fraley and Rao have developed a procedure for data, obtained using double-pen recorders. The technique involves using visible neon lines to produce a wave number scale on the infrared spectra that is to be measured. This book can prove valuable to researchers and scientists working in the field of molecular, nuclear or atomic physics.

  • Measurement Evaluation

    • 1 Edición
    • A. Boros
    • Inglés
    The information obtained about a measured object is called ``crude'' measurement information and must be related to the conditions under which the measurement took place. Using ``crude'' measurement information as a starting point, evaluation produces physically correctly interpreted data with their estimated (or corrected) error. Although a number of works deal with the evaluation of measurements, they either appeared a long time ago or serve essentially different aims. This book gives a comprehensive and current overview on the basic principles, aids, devices, and methods in the evaluation of measurements performed in all fields of technology and science in order to gain information about physical or technical objects.

    • Inglés
    Wide-band-gap semiconductors have been a research topic for many decades. However, it is only in recent years that the promise for technological applications came to be realized; simultaneously an upsurge of experimental and theoretical activity in the field has been witnessed. Semiconductors with wide band gaps exhibit unique electronic and optical properties. Their low intrinsic carrier concentrations and high breakdown voltage allow high-temperature and high-power applications (diamond, SiC etc.). The short wavelength of band-to-band transitions allows emission in the green, blue, or even UV region of the spectrum (ZnSe, GaN, etc.). In addition, many of these materials have favorable mechanical and thermal characteristics.Thes... proceedings reflect the exciting progress made in this field. Successful p-type doping of ZnSe has recently led to the fabrication of blue-green injection lasers in ZnSe; applications of short-wavelength light-emitting devices range from color displays to optical storage. In SiC, advances in growth techniques for bulk as well as epitaxial material have made the commercial production of high-temperature and high-frequency devices possible. For GaN, refinement of growth procedures and new ways of obtaining doped material have resulted in blue-light-emitting diodes and opened the road to the development of laser diodes. Finally, while the quality of artificial diamond is not yet high enough for electronic applications, the promise it holds in terms of unique material properties is encouraging intense activity in the field.This volume contains contributions from recognized experts presently working on different material systems in the field. The papers cover the theoretical, experimental and application-oriented aspects of this exciting topic.

    • Erich Merchand
    • Inglés
    Gradient Index Optics deals with the application of gradients in optical systems of classical types: gradient index lenses. The emphasis is on the theory and practice related to gradient index lenses. Only isotropic media are considered since they are the ones for which the refractive index at each point is independent of direction. Comprised of 12 chapters, this book begins with a historical background on the use of gradients in astronomy and developments in gradient index lenses, along with the underlying basic theory. The discussion then turns to spherical gradients, paying particular attention to rays, Maxwell's fisheye lens, the Luneburg lens, and astronomical refraction. Subsequent chapters focus on the ray trace in a spherical gradient; axial gradients and their use as an anti-reflection coating; radial gradients and ray tracing in a radial gradient; and fundamentals of aberration theory. The wood lens and ray trace in a general medium are also considered, together with methods for fabrication of gradient elements and measurement of index gradients using an approximate method and interferometric methods.

    • Inglés
    The essays in this book deal with of the problem of quantum tunnelling and related behavior of a microscopic or macroscopic system, which interacts strongly with an "environment" - this being some form of condensed matter. The "system" in question need not be physically distinct from its environment, but could, for example, be one particular degree of freedom on which attention is focussed, as in the case of the Josephson junction studied in several of the papers. This general problem has been studied in many hundreds, if not thousands, of articles in the literature, in contexts as diverse as biophysics and quantum cosmology. The editors have grouped together papers which are representative of the main trends in this area in the last fifteen years or so and sufficiently related in general spirit and terminology that common themes can be discerned. The contributions are primarily theoretical, but the comparison with experiment is discussed wherever possible.
