Digital Optical Measurement Techniques by Anonim Pdf

Due to its ruggedness and often contactless characteristics, optical systems are one of the most adopted, particularly when fast changes in displacement need to be measured. Moreover, due to the physical principles that support the operation of some of those systems (e.g., optical interferometry), they allow the measurement of linear displacements with resolutions and accuracies below the nanometer. Miniaturization and mass replications have begun to lead the optical industry in the transition from traditional analog to novel digital optics. Digital optics is information optics in its maturity. It assumes using digital processing units as an integral part of optical imaging and measurement systems. Digital processors are used both for control of optical systems and for processing optical signals. One of the main use of digital signal processing in optical imaging and measuring devices is data calibration, and, in particular, data denoising.Digital Optical Measurement Techniques presents cutting-edge information on the development and application of optical techniques and laser technology in engineering. As digital optics enter the realm of mainstream technology through the worldwide sale of consumer electronic devices, this timely book aims to present the topic of digital optics in an integrated way. Contributions are from eminent authors and researchers around the globe dealing with the practical use of devices and strategies, the estimation of results and advances and improvement of solutions and new theoretical foundations for experimental methods.This book details the state-of-the-art optical measurement capabilities available for full field dynamic response and surface topography measurements of MEMS devices. It describes how the optical measurement system is used for several of these examples. The principles of operation are important for understanding the inherent advantages and disadvantages of the technology used.

Optical Measurements by Franz Mayinger Pdf

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.

Laser Diagnostics and Optical Measurement Techniques in Internal Combustion Engines by Hua Zhao Pdf

The increasing concern about CO2 emissions and energy prices has led to new CO2 emission and fuel economy legislation being introduced in world regions served by the automotive industry. In response, automotive manufacturers and Tier-1 suppliers are developing a new generation of internal combustion (IC) engines with ultra-low emissions and high fuel efficiency. To further this development, a better understanding is needed of the combustion and pollutant formation processes in IC engines. As efficiency and emission abatement processes have reached points of diminishing returns, there is more of a need to make measurements inside the combustion chamber, where the combustion and pollutant formation processes take place. However, there is currently no good overview of how to make these measurements. Based on the author’s previous SAE book, Engine Combustion Instrumentation and Diagnostics, this book focuses on laser-based optical techniques for combustion flows and in-cylinder measurements. Included are new chapters on optical engines and optical equipment, case studies, and an updated description of each technique. The purpose of this book is to provide, in one publication, an introduction to experimental techniques that are best suited for in-cylinder engine combustion measurements. It provides sufficient details for readers to set up and apply these techniques to IC engines and combustion flows.

Optical Measurement of Surface Topography by Richard Leach Pdf

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.
