' ... I feel that the editors and authors are to be congratulated for successfully accomplishing their goal of compressing the quite diverse field of optical fibre sensor technology into a single, easy-to-read and well illustrated volume aimed at the non-specialist.'International Journal of Optoelectronics' ... However, the editors have additionally provided a refreshing angle with this book, by paying particular attention to the enabling technology incorporated into fibre sensors ... The subject matter is very practical and the treatment given in this book is a very thorough and comprehensive one. The book does present many state-of-the-art ideas, but not at the expense of detailed descriptions of enabling background technology. The presentation is excellent throughout with an extensive list of references grouped at the end of each chapter and a good overall subject index. The text is to be highly recommended to both designers, engineers and students alike.'Optics and Laser Technology
