Optical Measurements

Increasing possibilities of computer-aided data processing have caused a new revival of optical techniques in many areas of mechanical and chemical en gineering. Optical methods have a long tradition in heat and mass transfer and in fluid dynamics. Global experimental information is not sufficient for developing constitution equations to describe complicated phenomena in fluid dynamics or in transfer processes by a computer program . Furthermore, a detailed insight with high local and temporal resolution into the thermo-and fluiddynamic situations is necessary. Sets of equations for computer program in thermo dynamics and fluid dynamics usually consist of two types of formulations: a first one derived from the conservation laws for mass, energy and momentum, and a second one mathematically modelling transport processes like laminar or turbulent diffusion. For reliably predicting the heat transfer, for example, the velocity and temperature field in the boundary layer must be known, or a physically realistic and widely valid correlation describing the turbulence must be avail able. For a better understanding of combustion processes it is necessary to know the local concentration and temperature just ahead of the flame and in the ignition zone.

An accessible, introductory text explaining how to select, set up and use optical spectroscopy and optical microscopy techniques.

The measurement and characterisation of surface topography is crucial to modern manufacturing industry. The control of areal surface structure allows a manufacturer to radically alter the functionality of a part. Examples include structuring to effect fluidics, optics, tribology, aerodynamics and biology. To control such manufacturing methods requires measurement strategies. There is now a large range of new optical techniques on the market, or being developed in academia, that can measure areal surface topography. Each method has its strong points and limitations. The book starts with introductory chapters on optical instruments, their common language, generic features and limitations, and their calibration. Each type of modern optical instrument is described (in a common format) by an expert in the field. The book is intended for both industrial and academic scientists and engineers, and will be useful for undergraduate and postgraduate studies.

Devoted to new optical measurement techniques in industry as well as the life sciences, this book has a fresh perspective on the development of modern optical sensors, which are essential for the control of parameters in industrial and biomedical applications.

From the reviews: "Haus’ book provides numerous insights on topics of wide importance, and contains much material not available elsewhere in book form. [...] an indispensable resource for those working in quantum optics or electronics." Optics & Photonics News

Principles of Optical Fiber Measurements focuses on the optical fiber systems, which are being added to the telephone networks of various countries around the world. This book explores the significance of optical fiber systems in the increasing variety of fiber-related products on the market. Comprised of seven chapters, this book starts with an overview of the fiber fabrication process with emphasis on the method of measurements to reduce fiber loss in the field of optical communication. This text then examines the special methods to measure extremely low dispersion in single-mode fibers. Other chapters consider the measurement requirements of commercial fiber manufacturers to allow them to specify their products as well as for fiber users to verify that they get what they expect. The final chapter deals with the various measurement methods for determining the V value of fibers as well as the geometrical dimensions of fibers and preforms. This book is a valuable resource for specialists and readers who desire a better understanding of fiber specifications.
