This book presents a comprehensive examination of lasers and optical fibers in an hierarchical, three-tier system. Each chapter is Vdiveiwd efdu liln dteos tchrirpetei obnasic secti... Audience Biophysicists in industry; surgeons in all areas; electronics and chemical engineers; and optical fiber technologists. Book information • Published: October 1993 • Imprint: ACADEMIC PRESS • ISBN: 978-0-12-401940-9 Reviews "Dr. Katzir, an acknowledged expert on the use of optical fibers in medicine, has written his book for the novice and expert alike... [He] has provided many clear examples and figures to explain fundamental concepts. Furthermore, the emphasis in the fundamentals sections is on conceptual understanding; mathematical rigor is generally left to more appropriate texts... The book is extremely well illustrated and easy to read throughout. The technical jargon is minimal and the emphasis on concepts is universal. The instructive nature of the book makes this an excellent introductory text for the engineering and biophysics student, as well as the postdoctoral/medical fellow who is new to this interdisciplinary field of lasers and optical fibers in medicine. It should also serve as a good reference to this rather broad field." --OPTICAL ENGINEERING "This is a really excellent book, dealing with almost all aspects of the technology and application of medical lasers and optical fibres.

  • The UFO Technology Hackers Manual
    Final Edition By Michael McDonnough Cover Art by Michael McDonnough © Copyright 1998-2006 Michael McDonnough all rights reserved No resale or reprinting of this file without permission of the author but distribute freely at no charge. The UFO Technology Hackers Manual Preface This book is not a rehash of information covered in other books. Most of the information disclosed within has never appeared in book form before this writing however, if you have read, How To Build A Flying Saucer And Other Projects In Speculative Engineering (by TB Pawliki), this book starts where that author ends his, at the Solid State UFO. I will bring you up to speed on the state of the art in spacecraft drive potential. All information is compiled from publicly available government archives. Within the unknown and the unexplained, lie the parameters for a new paradigm. As scientist, inventors, and hackers, we must go forth bravely into this new territory. If we were to turn away, to return to our comfortable ignorance we may never do what we all dream, to advance science, technology, and human discovery to the next level. The reason for my writing this book is to bring, to the attention of the general public, information about space drive capabilities that human technology can accomplish that are way beyond what we are being told about in our schools, and our media outlets. These technologies must be known to the general public so that they will have the knowledge to "DEMAND ACCESS" to these capabilities. Soon, all mankind can go forth into Space and explore the New Frontier for ourselves.
