Photonic Instrumentation: Sensing and Measuring with Lasers is designed as a source for university-level courses covering the essentials of laser-based instrumentation, and as a useful reference for working engineers. Photonic instruments have very desirable features like non-contact operation and unparalleled sensitivity. They have quickly become a big industrial success, passing unaffected through the bubble years and, not any less important, well-established methods in measurement science. This book offers coverage of the most proven instruments, with a balanced treatment of the optical and electronic aspects involved. It also attempts to present the basic principles, develop the guidelines of design and evaluate the ultimate limits of performances set by noise. The instruments surveyed include: alignment instruments, such as wire diameter and particle size analyzers, telemeters, laser interferometers and self-mixing interferometers, and speckle pattern instruments, laser doppler velocimeters, gyroscopes, optical fiber sensors and quantum sensing. A few appendices offer convenient reference material for key principles on lasers, optical interferometers, propagation, scattering and diffraction.

The main aim of this book is to introduce the concept of photonic information processing technologies to the graduate and post-graduate students, researchers, engineers and scientists. It is expected to give the readers an insight into the concepts of photonic techniques of processing as a system, the photonic devices as required components which are applied in the areas of communication, computation and intelligent pattern recognition.

A wide variety of biomedical photonic technologies have been developed recently for clinical monitoring of early disease states; molecular diagnostics and imaging of physiological parameters; molecular and genetic biomarkers; and detection of the presence of pathological organisms or biochemical species of clinical importance. However, available in

The first comprehensive survey of state-of-the-art tunable micro-optics, covering advances in materials, components and systems.

An account of a three-year research program funded by the German government, in which physicists and physical chemists set off together with biologists and physicians to develop new techniques for medical and biological problems and ended up with sophisticated scientific solutions and innovative equipment, partly ready for the market. It not only includes a concise description of the new discoveries but also offers also an introduction to the various fields within optics.

The combination of color schlieren with high speed flash techniques has proved to be a valuable tool for investigating high speed transient events. Fully two dimensional refractive index information can be ob tained. The resolution on 35 mm film was sharp enough to allow 50 cm by 75 cm color enlargements. REFERENCES 1.
