Современные датчики

Справочник по современным датчикам можно назвать настольнойкнигой исследователя в любой области естествознания, поскольку внем изложены физические принципы, методы разработки и вариантыпрактического использования широкого спектра датчиков в самыхразнообразных областях применений. Книга издана на английскомязыке уже третий раз, и это не случайно, поскольку любая современнаясистема измерений не обходится без применения датчиков, которыеявляются «переводчиками» окружающей аналоговой природы на языкцифровой техники, т.е. можно сказать, что датчики являются «глазами,ушами и носами» кремниевых кристаллов.Последнее издание дополнено описанием датчиков, реализованныхпо самым современным технологиям. Речь идет об электромехани-ческих микродатчиках (MEMS) и об электрооптомеханических микро-системах (MEOMS), без которых был бы невозможен такой резкийпрогресс в областях беспроводных систем телекоммуникации и отдель-ных областях медицины и техники, наблюдаемый в последние годы.Книга является превосходным справочным пособием для студентов,исследователей, проектировщиков датчиков и специалистов, разраба-тывающих измерительные системы. This Book Is About Devices Commonly Called Sensors. Digital Systems, However Complex And Intelligent They Might Be, Must Receive Information From The Outside World That Is Generally Analog And Not Electrical. Sensors Are Interface Devices Between Various Physical Values And The Electronic Circuits Who Understand Only A Language Of Moving Electrical Charges. In Other Words, Sensors Are The Eyes, Ears, And Noses Of Silicon Chips. Unlike Other Books On Sensors, This Book Is Organized According To The Measured Variables (temperature, Pressure, Position, Etc.) That Make It Much More Practical And Easier To Read. In This New Edition Recent Ideas And Developments Have Been Added While Less Important And Non-essential Designs Were Dropped. Sections On Practical Designs And Use Of The Modern Micro-machining Technologies Have Been Revised Substantially. This Book Is A Reference Text That Can Be Used By Students, Researchers Interested In Modern Instrumentation (applied Physicists And Engineers), Sensor Designers, Application Engineers And Technicians Whose Job It Is To Understand, Select And/or Design Sensors For Practical Systems. The Scope Of This Book Is Rather Broad Covering Many Different Designs. Some Are Well Known, But Describing Them Is Still Useful For Students And Those Who Look For A Convenient Reference. It Is The Author’s Intention To Present A Comprehensive And Up-to-date Account Of The Theory (physical Principles), Design, And Practical Implementations Of Various Sensors For Scientific, Industrial, And Consumer Applications. About The Author: Jacob Fraden Holds A Ph. D. In Medical Electronics And Is The Ceo Of Advanced Monitors Corp., A Company That Produces Medical And Veterinary Temperature Sensors And Monitors.

The Development of faster, more accurate, more sensitive sensors continues, with scientists creating and refining new ways for translating physical values into electronic information. This authoritative handbook takes readers to the cutting edge of sensor technology, providing an expert assessment of current research at the crossroads where the digital, analog, and physical worlds meet. Written by one of the field's leading specialists, Handbook of Modern Sensors is the only book of its kind: a quick-access guide to the basic principles, design specifications, and uses of a number of important contemporary sensors and detectors. No other volume offers such a clearly written presentation of theoretical and practical information in such a streamlined format. Handbook of Modern Sensors begins with the basic physical principles that form the foundations of sensor design, then explores the interfaces between sensors and peripheral processing devices. This paves the way for the book's survey of current sensors - coverage organized by the type of variable being measured (from acceleration to vibration). While ranging across a wide variety of devices, the book emphasizes those that are less well known, whose technology is on the rise, and whose existence is making previously inaccessible measurements possible. Thoroughly revised and updated throughout, the Second Edition features new sections on acoustic waves temperature and on temperature and chemical sensors, plus a new chapter on manufacturing methods and materials. . Handbook of Modern Sensors, with its state-of-the-art perspective, is a valuable source of information for physicists and engineering professionals. Yet its easy-going writing style, clear descriptions, and focus on the fundamentals make the book supremely accessible to students as well. Seven years have passed since the publication of the previous edition of this book. During that time, sensor technologies have made a remarkable leap forward. The sensitivity of the sensors became higher, the dimensions became smaller, the sel- tivity became better, and the prices became lower. What have not changed are the fundamental principles of the sensor design. They are still governed by the laws of Nature. Arguably one of the greatest geniuses who ever lived, Leonardo Da Vinci, had his own peculiar way of praying. He was saying, “Oh Lord, thanks for Thou do not violate your own laws. ” It is comforting indeed that the laws of Nature do not change as time goes by; it is just our appreciation of them that is being re?ned. Thus, this new edition examines the same good old laws of Nature that are employed in the designs of various sensors. This has not changed much since the previous edition. Yet, the sections that describe the practical designs are revised substantially. Recent ideas and developments have been added, and less important and nonessential designs were dropped. Probably the most dramatic recent progress in the sensor technologies relates to wide use of MEMS and MEOMS (micro-electro-mechanical systems and micro-electro-opto-mechanical systems). These are examined in this new edition with greater detail. This book is about devices commonly called sensors. The invention of a - croprocessor has brought highly sophisticated instruments into our everyday lives. The Handbook's coverage of sensors is extensive, ranging from simple photodiodes to complex devices containing components in combination. It offers hard-to-find reference data on the properties of numerous materials and sensing elements and emphasizes devices that are less well-known, whose technology is still being refined, and whose use permits the measurement of variables that were previously inaccessible. "An ideal desktop reference for students, applied physicists and engineers, sensor designers, and technicians who select sensors for practical systems, the Handbook is also a perfect textbook for related courses."--Jacket
