FOREWORD THE <strong>FIBEROPTIC</strong> <strong>SENSOR</strong> <strong>TECHNOLOGY</strong> <strong>HANDBOOK</strong> The <strong>FIBEROPTIC</strong> <strong>SENSOR</strong> <strong>TECHNOLOGY</strong> <strong>HANDBOOK</strong> reflects the latest technology concerning the field of fiberoptic in general and fiberoptic sensors in particular. The fiberoptic sensor technology principles and practices laid down in this <strong>HANDBOOK</strong> will give the reader a solid basis for mastering a relatively new technology. Only a nominal general technical background is needed to fully comprehend its contents. The contributing authors have been as explicit and rigorous in their presentation as time and space constraints in this <strong>HANDBOOK</strong> would permit. All the material has been edited to ensure coherency and consistency. OPTICAL TECHNOLOGIES, INC. Optical Technologies, Inc. (OPTECH) is a young and rapidly growing corporation devoted to the research and development of useful fiberoptic sensor applications and to the advancement of fiberoptic sensor technology. OPTECH is recognized as a leader in this field. The cofounders of OPTECH, Dr. Charles M. Davis and Mr. Robert E. Einzig, who are also authors of this <strong>HANDBOOK</strong>, are pioneers in the field of fiberoptic sensor technology. Dr. Davis headed the branch at the Naval Research Laboratory that designed and produced the first fiberoptic hydrophore. He has since collaborated in the design of numerous other fiberoptic sensor systems. Mr. Einzig has also designed fiberoptic sensor systems for private research laboratories, industry and government. Finally, both men were the key contributors to the development of the Navy’s Fiber Optic Sensor System (FOSS) Program in 1977. Presently, their experience and talents are being applied at OPTECH where, together with other physicists and engineers specializing in fiberoptic sensing, advances in the field are continuing to be made. To date, OPTECH’S experience with fiberoptic sensors includes development of sensors for the measurement of temperature, pressure, acoustic signals, acceleration, magnetic fields, and seismic disturbances. AUTHORS Charles M. Davis, PhD. Currently Dr. Davis is Vice President of Optical Technologies, Inc. He has over 30 years of experience in acoustooptics and physical acoustics. As head of the Physical Acoustics Branch at the Naval Research Laboratory, he was instrumental in the development of the fiberoptic hydrophore and the establishment of the FOSS Program. Edward F. Carome, PhD. Currently Dr. Carome is a Professor of Physics at John Carroll University. He participated in the initial research at the Naval Research Laboratory that led to the development of the fiberoptic hydrophore. Martin H. Weik, D.SC. Currently Dr. Weik is a senior systems analyst at Dynamic Systems, Inc. Dr. Weik has written several comprehensive dictionaries in the fields of computers, information processing systems, fiberoptic, lightwave propagation, and general communications. Shaoul Ezekiel, D.SC. Currently Dr. Ezekiel is a Professor at MIT. He has conducted research concerned with ultraprecision measurements using optical techniques. More recently, he has investigated the use of passive resonators and fiberoptic interferometers for rotation measurements. Robert E. EinziR, MSEE. Currently Mr. Einzig serves as President of Optical Technologies, Inc. He has extensive applications experience in fiberoptic sensors and data transmission systems, which adds to his broad underwater acoustic sensor background.
