Preface

Metrology is the science of measurement. It covers all the practical and theoretical topics based on measurement, regardless of accuracy level and application area. Measurement processes, measurement methods and procedures, instrumentation, calibration, determina‐ tion of measurement systems, verification, measurement accuracy, measurement precision, measurement error, data acquisition, evaluation of measurement results, the formation of statistical evaluations and quality determinations are the main subjects of metrology. Met‐ rology is crucial for many sciences and technological developments as well. Since metrology helps to improve many other sciences, the book reflects in general metrology and some spe‐ cial metrological approaches at different fields such as radiation and frequency measure‐ ments in detail. This book also focuses on technical testing and control applications in the industry and intends the fundamentals of metrology concerning the related standards and systems of units. In addition, the book considers the calibration of measurement instruments and measurement uncertainties as the basic requirements of the related quality standards. Thanks go to all metrology scientists working for closer results to the reals.
