Preface
The laser Doppler and phase Doppler measuring techniques are both relatively
young. The laser Doppler technique was first proposed in 1964 but came into
widespread use only in the 1970s. The phase Doppler technique exhibited a
similar development about 20 years later. Both techniques share a number of
commonalties, not only in the hardware but also in the fact that both are most
widely used in the fluid mechanics community. Therefore the technical overlap
of the two techniques also extends to a strong 'user' overlap and this was one of
the prime motivations for addressing both techniques in one volume.
This book has arisen out of need. A comprehensive book about the phase
Doppler measurement technique does not exist. Neither are the more recent de
velopments of the laser Doppler technique weIl documented in a single volume.
The student or user of these techniques presently relies on a combination of
contributions from conference proceedings, journal publications and manu
facturers' documentation. Furthermore, the fundamentals involved come from a
wide variety of disciplines, e.g. electromagnetic theory, signal processing, etc.,
fields which are generally not so familiar within the fluid mechanies community.
This book is an attempt to consolidate some of this information for the reader.
The authors have intended this book to be both a reference book and an in
structional book. This expresses itself in quite a varied degree of complexity in
the different chapters. A reasonable attempt has been made to be thorough in
the citation of literature to direct the reader to many details wh ich cannot be in
cluded within the scope of this book. At the same time, the reader will find some
novel results in this book, especially on the subject of particle characterization.
In preparing this book, the authors have drawn on the experience and advice
of a large number of colleagues within their respective institutes who deserve
special mention and thanks. In Rostock this includes Dr. H. Bech, Dr. W. Fuchs,
Dr. W. Kröger and Prof. Dr. E. Müller. Prof. Dr. K. Bauckhage from the Univer
sity of Bremen at the Institute for Material Science initiated a joint project from
the Deutsche Forschungsgemeinschaft with Rostock, which stimulated new
ideas about the computation oflight scattering on small particles in homogene
ous and inhomogeneous fields. At the Physikalisch-Technische Bundesanstalt in
Braunschweig, where M.B. worked at the Department of Fluid Mechanics until
2000, the collaboration with Prof. Dr. D. Dopheide, Dr. R. Kramer, Dr. H. Müller
and Dr. V. Strunck was much appreciated. At the Lehrstuhl für Strömungs
mechanik in Erlangen, where C.T. worked until 1997, interaction with Prof. Dr.
G. Brenn, Dr. J. Domnick, Prof. Dr. F. Durst, Dr. A. Naqwi and T.-H. Xu is
gratefullyacknowledged. In Darmstadt the authors had the pleasure of working

closely with Dr. L Araneo, Dipl.-Ing. K. Heukelbach, Dr. H. Nobach and Dr. I.V.
Roisman on various application aspects.
The authors first came into contact with each other through a joint project
from the Volkswagen Foundation (Contract 1/66 487) and then through subse
quent grants from the Deutsche Forschungsgemeinschaft (Mu 1117/1, Tr 194/9).
The authors gratefully acknowledge the finaneial support of these funding agen
eies for enabling this initial collaboration and its continuation over the past
years.
Unavoidably there exist errors and omissions in this book and the authors
take full responsibility for these. Readers who have suggestions for improve
ments are welcome to contact the authors ([email protected]).
