Download or read book Frequency Standards written by Fritz Riehle and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of all measurement units, frequency is the one that may be determined with the highest degree of accuracy. It equally allows precise measurements of other physical and technical quantities, whenever they can be measured in terms of frequency. This volume covers the central methods and techniques relevant for frequency standards developed in physics, electronics, quantum electronics, and statistics. After a review of the basic principles, the book looks at the realisation of commonly used components. It then continues with the description and characterisation of important frequency standards from atomic clocks, to frequency stabilised lasers. The whole is rounded of with a discussion of topical applications in engineering, telecommunications, and metrology.

Available in PDF, EPUB and Kindle. Book excerpt: Up-to-Date Coverage of Stable and Accurate Frequency Standards The Quantum Physics of Atomic Frequency Standards: Recent Developments covers advances in atomic frequency standards (atomic clocks) from the last several decades. It explains the use of various techniques, such as laser optical pumping, coherent population trapping, laser cooling, and electromagnetic and optical trapping, in the implementation of classical microwave and optical atomic frequency standards. The book first discusses improvements to conventional atomic frequency standards, highlighting the main limitations of those frequency standards and the physical basis of the limitations. It then describes how advances in the theory and applications of atomic physics have opened new avenues in frequency standards. The authors go on to explore the research and development of new microwave and optical frequency standards before presenting the results in frequency stability and accuracy achieved with these new frequency standards. They also illustrate the application of atomic clocks in metrology, telecommunications, navigation, and other areas and give some insight into future work. Building on the success of the previous two volumes, this up-to-date, in-depth book examines the vast improvements to atomic clocks that have occurred in the last 25 years. The improved stability and accuracy enable the verification of physical concepts used in fundamental theories, such as relativity, as well as the stability of fundamental constants intrinsic to those theories.

Available in PDF, EPUB and Kindle. Book excerpt: The document is a tutorial Monograph describing various aspects of time and frequency (T/F). Included are chapters relating to elemental concepts of precise time and frequency; basic principles of quartz oscillators and atomic frequency standards; historical review, recent progress, and current status of atomic frequency standards; promising areas for developing future primary frequency standards; relevance of frequency standards to other areas of metrology including a unified standard concept; statistics of T/F data analysis coupled with the theory and construction of the NBS atomic time scale; an overview of T/F dissemination techniques; and the standards of T/F in the USA. The Monograph addresses both the specialist in the field as well as those desiring basic information about time and frequency. The authors trace the development and scope of T/F technology, its improvement over periods of decades, its status today, and its possible use, applications, and development in days to come.

Available in PDF, EPUB and Kindle. Book excerpt: This work reviews the principles underlying quantum-based atomic clocks, with introductory chapters placing them in context with the development of mechanical clocks and electronic quartz-controlled clocks. The book details design principles of the rubidium, cesium, hydrogen maser, and mercury ion standards; changes enabled by the advent of the laser; and the time-based global navigation systems, Loran-C and the Global Positioning System. The new edition includes such recent developments as clocks based on quantum resonance at optical frequency in individual ions confined in miniature electromagnetic traps. The Quantum Beat explores the subject with a minimum of mathematical formalism.
