In 1989 the time was hot to create a workshop series dedicated to the dicussion of the latest results in the automatic processing of fringe patterns. This idea was promoted by the insight that automatic and high precision phase measurement techniques will play a key role in all future industrial applications of optical metrology. However, such a workshop must take place in a dynamic environment. The- fore the main topics of the previous events were always adapted to the most interesting subjects of the new period. In 1993 new prin- ples of optical shape measurement, setup calibration, phase unwr- ping and nondestructive testing were the focus of discussion, while in 1997 new approaches in mu...
It is expected that ongoing advances in optics will revolutionise the 21st century as they began doing in the last quarter of the 20th. Such fields as communications, materials science, computing and medicine are leaping forward based on developments in optics. This new series presents leading edge research on optics and lasers from researchers spanning the globe.
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 guidelin...

Methods And Techniques Of Measurements Are Becoming Increasingly Important In Engineering In Recent Years Laboratory Programmes Have Been Modernized, Sophisticated Electronic Instrumentation Has Been Incorporated Into The Programme And Newer Techniques Have Been Developed. This Book Dwells On The Physical Aspects Of Measurement Techniques. For The Measurement To Be Meaningful, The Nature And Magnitude Of Error Should Be Known. The Book, Thus Begins With Error Analysis And Applications Of Statistical Principles To Attain A Measurement Value As Near The True Value As Possible. The Methods Of Measuring Mechanical Quantities Are Discussed Subsequently, Overing Both The Basic And Derived Quantities. Effort Has Been Made To Present The Subject In S.I. Units. Some Of The Recent Developments Such As Laser-Doppler Techniques, Holography, Have Also Been Included. The Coverage Is Such That The Book Will Be Useful Both Of Graduate And Post-Graduate Students And Will Also Serve As A Constant Reference For Researchers.
