Ring Interferometry


Book Description

This monograph is devoted to the creation of a comprehensive formalism for quantitative description of polarized modes’ linear interaction in modern single-mode optic fibers. The theory of random connections between polarized modes, developed in the monograph, allows calculations of the zero shift deviations for a fiber ring interferometer. The monograph addresses also the Sagnac effect and the Thomas precession. Devices such as gyroscopes, used in navigation and flight control, work based on this technology. Given the ever increasing market for navigation and air traffic, researchers and practitioners in research and industry need a fundamental and sound understanding of the principles. This work presents the underlying physical foundations.

Nanotechnology, sensor and measurement industries depend on these advances in optical interferometry for accuracy and profitability.




Optical Interferometry, 2e


Book Description

When the first edition of Optical Interferometry was published, interferometry was regarded as a rather esoteric method of making measurements, largely confined to the laboratory. Today, however, besides its use in several fields of research, it has applications in fields as diverse as measurement of length and velocity, sensors for rotation, acceleration, vibration and electrical and magnetic fields, as well as in microscopy and nanotechnology. Most topics are discussed first at a level accessible to anyone with a basic knowledge of physical optics, then a more detailed treatment of the topic is undertaken, and finally each topic is supplemented by a reference list of more than 1000 selected original publications in total. - Historical development of interferometry - The laser as a light source - Two-beam interference - Techniques for frequency stabilization - Coherence - Electronic phase measurements - Multiple-beam interference - Quantum effects in optical interference - Extensive coverage of the applications of interferometry, such as measurements of length, optical testing, interference microscopy, interference spectroscopy, Fourier-transform spectroscopy, interferometric sensors, nonlinear interferometers, stellar interferometry, and studies of space-time and gravitation




Interferometry


Book Description

This book provides the most recent studies on interferometry and its applications in science and technology. It is an outline of theoretical and experimental aspects of interferometry and their applications. The book is divided in two sections. The first one is an overview of different interferometry techniques and their general applications, while the second section is devoted to more specific interferometry applications comprising from interferometry for magnetic fusion plasmas to interferometry in wireless networks. The book is an excellent reference of current interferometry applications in science and technology. It offers the opportunity to increase our knowledge about interferometry and encourage researchers in development of new applications.




Albert A. Michelson and his Interferometer


Book Description

This book develops an astonishing conceptual connection between many concepts in modern physical sciences and related technologies, all of which have their roots in the Interferometer, a spectroscopic instrument created by Albert Michelson in 1880. After describing the place of the Interferometer amongst other historic, technical inventions, the book discusses the Michelson-Morley experiment (the basis of Einstein’s relativity theories) and the fine details of atomic spectral lines observed by Michelson (the basis of quantum mechanics and Dirac’s relativistic equation). It then covers nuclear magnetic resonance and applications such as atomic clocks, Global Positioning Systems and Magnetic Resonance Imaging, all derived from Michelson's discoveries. It also describes the recent detection, with a km-size Michelson’s Interferometer, of gravitational waves emitted by the merger of neutron star and black hole binaries.




Optical Frequency-Modulated Continuous-Wave (FMCW) Interferometry


Book Description

Optical interference plays a prominent role in scientific discovery and modern technology. Historically, optical interference was instrumental in establishing the wave nature of light. Nowadays, optical interference continues to be of great importance in areas such as spectroscopy and metrology. Thus far, the physical optics literature has discussed the interference of optical waves with the same single frequency (i.e., homodyne interference) and the interference of optical waves with two different frequencies (i.e., heterodyne interference), but it hardly ever deals with the interference of optical waves whose frequencies are continuously modulated (i.e., frequency-modulated continuous-wave int- ference). Frequency-modulated continuous-wave (FMCW) interference, which was originally investigated in radar in the 1950s, has been recently introduced in optics. The study of optical FMCW interference not only updates our kno- edge about the nature of light but also creates a new advanced technology for precision measurements. This book introduces the principles, applications, and signal processing of optical FMCW interference. The layout of this book is straightforward. Chapter 1 gives a short introduction to optical FMCW interferometry by considering the historical development, general concepts, and major advantages provided by this new technology. Chapter 2 focuses on the principles of optical FMCW interference. Three different versions of optical FMCW interference— sawtooth-wave optical FMCW interference, triangular-wave optical FMCW interference, and sinusoidal-wave optical FMCW interference—are discussed in detail. Moreover, multiple-beam optical FMCW interference and multip- wavelength optical FMCW interference are also discussed by this chapter.

As such, having all these together in one volume will go a long way to meet the requirements of the candidates learning this subject nowadays.




The Very Large Telescope Interferometer Challenges for the Future


Book Description

The last quarter of the 20th century witnessed the rebirth and maturing of optical interferometry and associated technologies. Major successes spanning from direct detection of stellar pulsations to imaging in the optical were achieved with test-bed systems, some of which have now evolved to facilities open to the astronomical community. The intense activity and rapid growth of this field are a clear sign that interferometry will be a major observational tool in this century both from ground and space. The VLTI is the largest ground-based interferometric facility combining four 8.2-m telescopes with up to eight 1.8-m telescopes. This facility is the first opened on a shared risk basis in 2002, a milestone for the astronomical community. The combination of enhanced sensitivity and common user support bring into grasp a vastly unexplored astrophysical territory. This book presents state of the art optical interferometry in astrophysics. We emphasise new VLTI users by including tutorials in optical interferometry theory and practice, and related instrumentation, as well as reviews in stellar formation and evolution, and extragalactic science.
