Book Description
When Faraday performed the very first experiments on electromagnetic effects, which form the very foundation of modern civilization since virtually everything electrical utilizes them, he was asked of what use his experiments were. He is said to have replied: "What is the use of a baby?" That reply might also be given to those who asked what was the use of basic research which resulted in the development of the laser and holography. Brigadier General Leo A.Kiley, Commander, Office of Aerospace Research, USAF, in his remarks before the Society of Photo-Optical Instrumentation Engineers at the opening ceremony of the Seminar on Holography held at San Francisco, California, in May 1968, declared, "It has been said that in the twenty-first century at least half of the jobs that will exist then do not exist today. But be that as it may, I am sure that holography will be common place. " And later "Even in its embryonic state today, the concept of holography is providing real world applications to the scientific community and I feel that continued rapid growth can be predicted." Now, only three years after these statements, the development of holography is extraordinary on the scientific side and very promising from the point of view of proven and potential applica tions. Holography looks like an emerging technique, a valuable tool for engineers.

Book Description
The motivation for the research that is described in these volumes is the wish to explain things in terms of their underlying causes, rather than merely being satisfied with phenomenological descriptions. When this reductionist approach is applied to information processing it allows the internal structure of information to be analysed, so information processing algorithms can then be derived from first principles. One of the simplest examples of this approach is the diagonalisation of a data covariance matrix – there are many variants of this basic approach, such as singular value decomposition – in which the assumed independent components of high-dimensional data are identified and extracted. The main limitation of this type of information analysis approach is that it is based on linear algebra applied globally to the data space, so it is unable to preserve information about any local data structure in the data space. For instance, if the data lives on a low-dimensional curved manifold embedded in the data space, then only the global properties of this manifold would be preserved by global linear algebra methods. In practice, data whose high-dimensional structure is non-trivial typically lives on a noisy version of a curved manifold, so techniques for analysing such data must automatically handle this type of structure. For instance, a blurred image of a point source is described by its underlying degrees of freedom – i.e. the position of the source – and as the source moves about it generates a curved manifold that lives in the high-dimensional space of pixel values of the sampled image. The basic problem is then to deduce the internal properties of this manifold by analysing examples of such images. A more challenging problem would be to extend this analysis to images that contain several overlapping blurred images of point sources, and so on. There is no limit to the complexity of the types of high-dimensional data that one might want to analyse. These methods then need to be automated so that they do not rely on human intervention, which would then allow them to be inserted as “components” into information processing networks. The purpose of the research that is described in these volumes is to develop principled information processing methods that can be used for such analysis. Self-organising information processing networks arise naturally in this context, in which ways of cutting up the original manifold into simpler pieces emerge automatically.

Book Description
Some Aspects of Vacuum Ultraviolet Radiation Physics presents some data on the state of research in vacuum ultraviolet radiation in association with areas of physics. Organized into four parts, this book begins by elucidating the optical properties of solids in the vacuum ultraviolet region (v.u.v.), particularly the specific methods of determination of optical constants in v.u.v., the properties of metals, and those of ionic insulators. Part II deals with molecular spectroscopy, with emphasis on the spectra of diatomic and simple polyatomic molecules, paraffins, and condensed phases. Part III focuses on some aspects of emission spectroscopy in the v.u.v. in relation to laboratory plasmas. The last part describes the image formation by concave gratings, spectrophotometry, and diffusion by surfaces. This book will be very valuable to physicist and graduate students inclined to this field of interest.

Book Description
In the 10 years prior to publication the quantity of research on eye movements as they pertain to psychological processes had been increasing at a rapid rate. Originally published in 1976, the editors’ purpose was to bring together investigators representing different theoretical positions and methodological approaches to present their recent findings, to debate the theoretical points of view, and to identify and discuss the major research problems on eye movements at the time. An attempt was made to invite participants ranging all the way from promising graduate students through the established authorities in the field. The result was an intensive three-day session with meetings from early morning until late into the evening with much opportunity for formal and informal group discussion. The edited papers and transcripts of the discussions are the contents of this book.

Book Description
This book provides all the essential and best elements of Kidger's many courses taught worldwide on lens and optical design. It is written in a direct style that is compact, logical, and to the point--a tutorial in the best sense of the word. "I read my copy late last year and read it straight through, cover to cover. In fact, I read it no less than three times. Its elegant expositions, valuable insights, and up-front espousal of pre-design theory make it an outstanding work. It's in the same league with Conrady and Kingslake." Warren Smith.
