This textbook provides a unified approach to acoustics and vibration suitable for use in advanced undergraduate and first-year graduate courses on vibration and fluids. The book includes thorough treatment of vibration of harmonic oscillators, coupled oscillators, isotropic elasticity, and waves in solids including the use of resonance techniques for determination of elastic moduli. Drawing on 35 years of experience teaching introductory graduate acoustics at the Naval Postgraduate School and Penn State, the author presents a hydrodynamic approach to the acoustics of sound in fluids that provides a uniform methodology for analysis of lumped-element systems and wave propagation that can incorporate attenuation mechanisms and complex media. This view provides a consistent and reliable approach that can be extended with confidence to more complex fluids and future applications. Understanding Acoustics opens with a mathematical introduction that includes graphing and statistical uncertainty, followed by five chapters on vibration and elastic waves that provide important results and highlight modern applications while introducing analytical techniques that are revisited in the study of waves in fluids covered in Part II. A unified approach to waves in fluids (i.e., liquids and gases) is based on a mastery of the hydrodynamic equations. Part III demonstrates extensions of this view to nonlinear acoustics. Engaging and practical, this book is a must-read for graduate students in acoustics and vibration as well as active researchers interested in a novel approach to the material.

This third volume of the series Lectures in Optics provides a comprehensive presentation of the wave optics effects. The arguments underlying the concept of light—as either a wave or a particle—were part of the greatest revolution in physics, which, in the early 20th century, bore modern quantum and atomic optics. These fundamental advances set the stage for a crucial outcome, the laser. Many aspects of optics are strongly dependent on light’s wave nature, including polarization (owing to the vector nature of light), absorption and dispersion (owing to the complex nature of the refractive index and the quantum nature of the photon), as well as interference and diffraction. The latter two effects are perhaps the greatest manifestations of the wave nature of light and provide an excellent demonstration of the power and simplicity of Fourier optics. After covering all of these effects in detail, Wave Optics introduces the concepts involved in laser light and its applications, engaging a historical and didactic approach. This book is suitable for advanced levels of Wave Optics courses in physics and engineering curricula, graduate programs, and professional programs, including optometric education. Each chapter ends with a simple yet adequate summary of the main points, aiming to reinforce an understanding of the covered material. Selfassessment is facilitated by ample practice examples, exercises, and quizzes.

Dieser Buchtitel ist Teil des Digitalisierungsprojekts Springer Book Archives mit Publikationen, die seit den Anfangen des Verlags von 1842 erschienen sind. Der Verlag stellt mit diesem Archiv Quellen fur die historische wie auch die disziplingeschichtliche Forschung zur Verfugung, die jeweils im historischen Kontext betrachtet werden mussen. Dieser Titel erschien in der Zeit vor 1945 und wird daher in seiner zeittypischen politisch-ideologischen Ausrichtung vom Verlag nicht beworben.

Acoustic Emission and Related Non-destructive Evaluation Techniques in the Fracture Mechanics of Concrete: Fundamentals and Applications, Second Edition presents innovative Acoustic Emission (AE) and related non-destructive evaluation (NDE) techniques that are used for damage detection and inspection of aged and deteriorated concrete structures. This new edition includes multi-modal applications such as DIC, thermography, X-ray and in-situ implementations, all of which are helpful in better understanding feasibility and underlying challenges. This new edition is an essential resource for civil engineers, contractors working in construction, and materials scientists working both in industry and academia.

Mit ungeheurer Geschwindigkeit hat auch in Deutschland der Siegeszug des Rundfunks eingesetzt. Es ist daher nicht mehr notig, ausfiihrlich die Annehmlichkeiten zu schildern, die der Besitz eines Rundfunkempfangers mit sich bringt. Die meisten anderen bisher erschienenen Biicher wiirdigen diese Seite besonders. Leider gibt es bisher kein Buch in deutscher Sprache, das die andere Seite der Radiotelephonie wiirdigt, namlich ein Buch nur fiir jene, welchen nicht primar an der Giite eines Radiokonzertes und an der Bequemlichkeit der Apparatur gelegen ist, sondern welchen das Gebiet der Radiotelephonie ein willkommener Tummelplatz ihres technischen Wissensdurstes, ein willkommenes Mittel fiir die Erprobung ihrer Handfertigkeit ist. Ihnen liegt nicht daran, etwas Bestimmtes abzuhoren, sie wollen nicht nur GroBen des Gesanges horen, ihnen sind die schnarrenden Tone eines altmodischen, entfernten Senders gleiche Musik. Man kann diese Leute sehr leicht von den eigentlichen Horern unterscheiden. Fragt man einen solchen, ob man heute hei ihm horen kann, so erhalt man oft zur Antwort: Mein Apparat ist gerade im Umhau.

Discover the history behind the semiconductor laser diode that has enabled so many of the modern optomechanical devices we enjoy - the vertical cavity surface emitting laser - and its creator, Kenichi Iga. Translated from the original Japanese edition, this book charts a course through the author's life and the evolution of the laser industry, exploring the scientific, economic, and personal developments that have occurred over the last sixty years.

This second volume of the series Lectures in Optics develops a thorough presentation of geometrical optics effects. The book begins by discussing refraction and reflection off single surfaces, both flat and spherical. Presented next are the essential building elements, optical power and beam vergence, which are paramount in imaging because the incident vergence is added to the element’s power to produce the vergence leaving the optical element. Imaging definitions and formulation are covered next, followed by the power configurations and imaging arrangements possible with a single element, a single lens, and a mirror for real and virtual objects. Next, two more parameters are introduced: the extent of an element along the optical axis (thick lenses and lens systems) and the extent of an element perpendicular to the optical axis (stops and pupils). The way image quality is affected by the transverse restriction of light is then discussed, including resolution and image blur. Finally, the book introduces the concepts of optical aberrations as a consequence of a violation of the paraxial approximations. This book is suitable for all Geometrical Optics courses at college, graduate school, or professional school levels, such as physics, engineering, visual science, or optometry programs. Comprehensive practice examples, exercises, and quizzes throughout the chapters reinforce an understanding of the covered material.
