`PREFACE TO THE FIRST EDITION
`
`THE idea of writing this book was a result of frequent enquiries about the possibility
`of publishing in the English language a book on optics written by one of us“ more than
`twenty—five years ago. A preliminary survey of the literature showed that numerous
`researches on almost every aspect of optics have been carried out in the intervening
`' years, so that the book no longer gives a comprehensive and balanced picture of the
`field. In consequence it was felt that a translation was hardly appropriate;
`instead
`a substantially new book was prepared, which we are now placing before the reader.
`In planning this book it soon became apparent that even if only the most important
`developments which took place since the publication of Optik were incorporated, the
`book would become impracticably large.
`It was,
`therefore, deemed necessary to
`restrict its scope to a narrower field. Optiic itself did not treat the whole of optics.
`The optics of moving media, optics of X-rays and y rays, the theory of spectra and the
`full connection between optics and atomic physics were not discussed; nor did the
`old book consider the effects of light on our visual sense Organ—the eye. These
`subjects can be treated more appropriately in connection with other fields such as
`relativity, quantum mechanics, atomic and nuclear physics, and physiology.
`In this
`book not only are these subjects excluded, but also the classical molecular optics which
`was the subject-matter of almost half of the German book. Thus our discussion is
`restricted to those optical phenomena which may be treated in terms of MAXWELL‘s
`phenomenological theory. This includes all situations in which the atomistic structure
`of matter plays no decisive part. The connection with atomic physics, quantum
`mechanics, and physiology is indicated only by short references wherever necessary.
`The fact that, even after this limitation, the book is much larger than Optil'c, gives
`some indication about the extent of the researches that have been carried out in
`classical optics in recent times.
`We have aimed at giving, within the framework just outlined, a reasonably com-
`plete picture of our present knowledge. We have attempted to present the theory in
`such a way that practically all the results can be traced back to the basic equations of
`MaxwuLL's electromagnetic theOry, from which our whole consideration starts.
`In Chapter I the main preperties of the electromagnetic field are discussed and the
`sheet of matter on the propagation of the electromagnetic disturbance is described
`formally, in terms of the usual material censtants. A more physical approach to the
`question of influence of matter is developed in Chapter II: it is shown that in the
`presence of an external incident field, each volume element of a material medium
`may be assumed to give rise to a secondary (scattered) wavelet and that the combina-
`tion of these wavelets leads to the observable, macroscopic field. This approach is of
`considerable physical significance and its power is illustrated in a later chapter
`(Chapter XIII—in connection with the diffraction of light by ultrasonic waves, first
`treated in this way by A. B. Bums and W. J. NOBLE; Chapter XII was contributed
`by Prof. BHATIA himself.
`A considerable part of Chapter III is devoted to showing how geomelfl'iml optics
`follows from MswaLL’s wave theory as a limiting case of short wavelengths.
`In
`addltlon to discussing the main properties of rays and wave-fronts, the vectorial

`PREFACE TO THE rins'r EDITION
`
`aspects of the problem (propagation of the directions of the field vectors) are also
`considered. A detailed discussion of the foundations of geometrical Optics seemed to
`us desirable in view of the important developments made in recent years in the related
`field of microwave optics (optics of short radio waves). These developments were
`often stimulated by the close analogy between the two fields and have provided
`new experimental techniques for testing the predictions of the theory. We found it
`convenient
`to separate the mathematical apparatus of geometrical optics-«the
`calculus of variations—~from the main text; an appendix on this subject (Appendix I)
`is based in the main part on unpublished lectures given by D. HILBER’I‘ at Gettingen- "
`University in the early years of this century. The following appendix (Appendix II),
`contributed by Prof. D. Gases, shows the close formal analogy that exists between
`geometrical Optics, classical mechanics, and electron optics, when these subjects are
`presented in the language of the calculus of variations.
`We make no apology for basing our treatment of geometrical theory of imaging
`(Chapter IV) on HAMILTon’s classical methods of characteristic functions. Though
`these methods have found little favour in connection with the design of optical instru-
`ments, they represent nevertheless an essential tool for presenting in a unified manner
`the many diverse aspects of the subject. It is, of course, possible to derive some of the
`results more simply from ad toe assumptions; but, hmvever valuable such an approach
`may be for the solution of individual problems, it cannot have more than illustrative
`value in a book concerned with a systematic development of a theory-from a. few
`simple postulates.
`The defect of optical images (the influence of aberrations} may be studied either
`by geometrical optics (appropriate when the aberrations are large), or by difiraction
`theory (when they are sufficiently small). Since one usually proceeds from quite
`different starting points in the two methods of treatments, a comparison of results
`has in the past not always been easy. We have attempted to develop a more unified
`treatment, based on the concept of the deformation of wave-fronts. In the geometrical
`analysis of aberrations (Chapter V) we have found it possible and advantageous to
`follow, after a slight modification of his eikona], the old method of K. SCHWARZSCHILD.
`The chapter on diifraetion theory of aberrations (Chapter IX) gives an account of
`the NIJBOERZERNIKE theory and also includes an introductory section on the
`imaging of extended objects, in coherent and in incoherent illumination, based on the
`techniques of Founrnn transforms.
`Chapter VI, contributed by Dr. P. A. WAYMAN, gives a brief description of the
`main image-forming optical systems.
`Its purpose is to provide a framework for
`those parts of the book which deal with the theory of image formation.
`Chapter VII is concerned with the elements of the theory of interference and with
`interferOmeters. Some of the theoretical sections have their nucleus in the corre-
`
`sponding sections of Optik, but the chapter has been completely re-written by Dr.
`W. L. WILCOCK, who has also considerably broadened its scope.
`Chapter VIII is mainly concerned with the anssEL-KIRUHHOFF diffraction theory
`and with some of its applications. In addition to the usual topics, the chapter includes
`a detailed discussion of the central problem of optical image formation—the analysis
`of the three-dimensional light distribution near the geometrical focus. An account is
`also given of a less familiar alternative approach to diffraction, based on the notion
`0f the boundary diffraction wave of T. Y0 UNG.
`. The cl’lapters so far referred to are mainly concerned with perfectly monochromatic
`{and therefore UGmpletely coherent) light, produced by point sources. Chapter X
`deals Wlth the more realistic case of light produced by sources of finite extension and

`
`covering a finite frequency range. This is the subject of partial coherence, Where
`considerable progress has been made in recent years. In fact, a systematic theory of
`interference and dili‘raction with partially coherent light has now been developed.
`This chapter also includes an account of the closely related subject of partial polariza-
`tion, from‘the standpoint cf_-C(iherence theory.
`Chapter XI deals with rigorous diffraction theory, a field that has witnessed a
`tremendous development over the period of the last twenty years} stimulated largely
`by advances in the ultra-shortwave radio techniques. This chapter was contributed
`by Dr. P. C. CLEMMOW who also prepared Appendix III, which deals with the
`mathematical methods of steepest descent and stationary phase.
`The last two chapters, Optics of Metals (Chapter XIII) and Optics of Crystals
`(Chapter XIV} are based largely on the corresponding chapters of Optik, but were
`revised and extended with the help of Prof. A. M. Tamoaand Dr. A. B... STOKES
`respectively. These two subjects are perhaps discussed in less detail than might
`seem appropriate. However, the Optics of metals can only be treated adequately
`with the help of quantum mechanics of electrons, which is outside the scope of this
`book.
`In crystal Optics the centre of interest has gradually shifted from visible
`radiation to X-rays, and the progress made in recent years has been of a technical
`rather than theoretical nature.
`
`Though we have aimed at producing a book which in its methods of presentation
`and general approach would be similar to Optz'k, it will be evident that the present
`book is neither a translation of Optiic, nor entirely a compilation of known data. As
`regards our own share in its production, the elder co-author (M. B.) has contributed
`that material from Optik which has been used as a basis for some of the chapters in
`the present treatise, and has taken an active part in the general planning of the
`11001: and in numerous discussions concerning disputable points, presentation, etc.
`Most of the compiling, writing, and checking of the text was done by the younger
`co-author (E. W.).
`Naturally we have tried to use systematic notation throughout the book. But in a
`_ book that covers such a wide field, the number of letters in available alphabets is far
`too limited. We have, therefore, not always been able to use the mostelegant notation
`but we hope that we have succeeded, at least, in avoiding the use in any one section
`of the same symbol for different quantities.
`In general we use vector notation as customary in Great Britain. After much
`reflection we rejected the use of the nabla operator alone and employed also the
`customary “div”, “grad”, and “curl". Also, We did not adopt the modern electro-
`technical units, as their main advantage lies in connection with purely electromagnetic
`measurements, and these play a negligible part in our discussions; moreover, we
`hope, that if ever a second volume (Molecular and Atomic Optics) and perhaps a'third
`volume (Quantum Optics) is written, the C.G.S. system, as used in Theoretical Physics,
`will have returned to favour. Although, in this system of units, the magnetic per-
`meability p, of most substances differs inappreciably from unity at optical frequencies,
`we have retained it in some of the equations. This has the advantage of greater
`symmetry and makes it possible to derive “dual” results by making use of the
`symmetry properties of MAXWEIL'S equations. For time periodic fields we have used.
`in complex representation, the factor exp (— imt) throughout.

`references that are given, and which, we hope, include the most important papers, are
`to help the reader to gain some orientation in the literature; an omission of any
`particular reference should not be interpreted as due to our lack of regard for its merit.
`In conclusion it is a pleasure to thank many friends and colleagues for advice and
`help. In the first place we wish to record our gratitude to Professor D. Genoa for useful
`advice'and assistance in the early stages of this project, as well as for providing
`a draft concerning his ingenious method of reconstructed wave-fronts (§ 8.10). We
`are also greatly indebted to Dr. F. ABELES, who prepared a draft, which is the back-
`bone of § 1.6, on the propagation of electromagnetic waves through stratified media,
`a field to which he himself has made a substantial contribution. We have also
`benefited by advice on this subject from Dr. B. H. BILLINGS.
`We are much indebted to Dr. H. H. Harms, Dr. R. A. Savanna, Dr. W. T.
`WELFDRD and Dr. G. WYLLIE for critical comments and valuable advice, and to
`them and also to Dr. G. BLACK, Dr. H. J. J. Bunnies, Dr. N. CHAKO, Dr. F. D. KAHN,
`Mr. A. NISBET, Dr. M. Ross and Mr. R. M. SELLITro for scrutinizing various sections

`dichroie materials. Dr. F. D. KAHN helped with proof-reading and Dr. P. ROMAN and
`Mrs. M. PODOLANSKI with the preparation of the author index.
`The main part of the writing was done at the Universities of Edinburgh and
`Manchester. The last stages were completed whilst one of the authors (E. W.) was
`a guest at the Institute of Mathematical Sciences, New York University. We are
`grateful to Professor M. KLINE, Head of its Division of Electromagnetic Research,
`for his helpful interest and for placing at our disposal some of the technical facilities
`of the Institute.

`PREFACE TO THE SECOND EDITION
`
`ADVANTAGE has been taken in the preparation of a. new edition of this work to make a.
`number of corrections of errors and misprints, to make a few minor additions and to
`include some new references.
`
`Since the appearance of the first edition almost exactly three years ago, the first
`optical masers (lasers) have been developed. By means of these devices very intense
`and highly coherent light beams may be produced. 1Whilst it is evident that optical
`masers will prove of considerable value not only for optics but also for other sciences
`and for technology. no account of them is given in this new edition. For the basic
`principles of maser action have roots outside the domain of classical electromagnetic
`theory on which considerations of this book are based. We have. however. included
`a few references to recent researches in which light generated by optical masers was
`utilized or which have been stimulated by the potentialities of these new optical
`devices.
`
`We wish to acknowledge our gratitude to a number of readers who drew our
`attention to errors and misIn-ints. We are also obliged to Dr. B. Kanczswsxi and
`Mr. C. L. MEIITA for assistance with the revisions.
