This book demonstrates the implementation of an automated measuring system for very efficient measurement of chromatic dispersion, which uses a modulation phase shift method over long haul of optical single mode fiber. The authors show how a new scheme for measuring chromatic dispersion is adopted in conjunction with a tunable laser (TLS), providing the optical power at required wavelength and digital oscilloscope (DOSC) for measuring the phase difference between microwave signals from transmitter and microwave signals at the receiver. This is a novel approach for real-time chromatic dispersion in optical systems such as optical fibers. The setup used is very simple, accurate and cost effective, compared to other methods such as direct measurement, differential mode delay, polarization mode dispersion measurement and phase delay method.

"Realizing the potential of the fiber optic gyro, like the ring laser gyro, has been a long and expensive process. Many researchers have made important enabling contributions, and many more engineers have worked diligently for many years on solving the problems associated with realizing viable inertial navigation and guidance produce at affordable costs. This book arose from efforts to form a special session to commemorate the fortieth anniversary of the first hardware demonstration of the fiber gyro in 1976 by Vali and Shorthill. The chapters contain contributions from key engineers and scientists who have worked from as early as 1977 to the present on manufacturing high-performance fiber gyros for many applications"--

Major challenges in nanoparticle and nanocomposite development are the control of particle size and shape, and to achieve uniform particle dispersion. In this book, the application of optical coherence tomography (OCT) for nanocomposite and nanoparticle characterization is investigated. Industrial requirements are robustness, small system cost and size, and an open path towards parallelization. We design and investigate silicon photonic integrated OCT systems that comply with these requirements.
