Optical Image Formation and Processing
Author: M Francon
Publisher: Elsevier
ISBN: 0323159591
Category : Science
Languages : en
Pages : 233
Book Description
Optical Image Formation and Processing describes modern physical optics, particularly concerning interference, diffraction, and a simplified theory of partial coherence. The book also discusses polarization, with emphasis on interference phenomena on polarized light. An image is formed in terms of the filtering of spatial frequencies, filtering that is due to transfer function. The text explains holography—a reconstruction of the image of an object beginning from the diffraction patterns produced by the object. A computer can also create artificial variations from the photographic plate which records the hologram, and can synthesize the hologram. The book cites an example of the synthesis of a hologram by a computer using the principle of binary holograms. The text also reviews some experiments dealing with the properties of lasers associated with temporal coherence and power. The book explains that lasers can carry large amounts of information due to their very high frequencies in the order of 300, 000 gigahertz, and recommends the use of optical fibers as the transmission medium instead of using open air. This book can prove useful for technicians, students, and professor connected with optical physics.

The Geometry of Multiple Images
Author: Olivier Faugeras
Publisher: MIT Press
ISBN: 9780262562041
Category : Computers
Languages : en
Pages : 682
Book Description
This book formalizes and analyzes the relations between multiple views of a scene from the perspective of various types of geometries. A key feature is that it considers Euclidean and affine geometries as special cases of projective geometry. Over the last forty years, researchers have made great strides in elucidating the laws of image formation, processing, and understanding by animals, humans, and machines. This book describes the state of knowledge in one subarea of vision, the geometric laws that relate different views of a scene. Geometry, one of the oldest branches of mathematics, is the natural language for describing three-dimensional shapes and spatial relations. Projective geometry, the geometry that best models image formation, provides a unified framework for thinking about many geometric problems are relevant to vision. The book formalizes and analyzes the relations between multiple views of a scene from the perspective of various types of geometries. A key feature is that it considers Euclidean and affine geometries as special cases of projective geometry. Images play a prominent role in computer communications. Producers and users of images, in particular three-dimensional images, require a framework for stating and solving problems. The book offers a number of conceptual tools and theoretical results useful for the design of machine vision algorithms. It also illustrates these tools and results with many examples of real applications.

Image Formation from Coherence Functions in Astronomy
Author: C. van Schooneveld
Publisher: Springer Science & Business Media
ISBN: 9400994494
Category : Science
Languages : en
Pages : 321
Book Description
The IAU Colloquium No.49, on the formation of images from spatial coherence functions in astronomy, was held at Groningen, the Netherlands, during the period 10-12 August 1978. The colloquium was attended by 108 participants from 14 countries (U.S.A. 29, the Netherlands 20, U.K. 19, Germany 10, France 7, Australia 5, Canada 5, Japan 4, India 2, New Zea land 2, Sweden 2, Argentina I, Belgium I, Israel I). It was sponsored by the Netherlands Foundation for Radio Astronomy, the International Astronomical Union, the Department of Education and Sciences, the Union Radio-Scientifique Internationale, the Leiden Kerkhoven-Bosscha Foundat ion and the State University at Groningen. This volume contains 36 of the 37 papers presented. Nearly all papers are followed by a sununary of the discussion that took place after their presentation. A few papers, published in full elsewhere, are given only as abstracts. The majority of the papers are related to aperture synthesis in radio astronomy; a small number deal with optical astronomy and with applications in acoustics and medicine. The presentations are divided in 7 groups: aperture synthesis and its deficiencies, the problem of limited or missing phase information, techniques for processing and data display, optical interferometric methods, maximum entropy image reconstruction, other image improvement methods, and a survey of image formation from projections. Each group contains one or two invited lectures (see Table of Contents), intended as surveys of particular areas; on the average they occupy twice as many pages as the other papers.

Theory of Remote Image Formation
Author: Richard E. Blahut
Publisher: Cambridge University Press
ISBN: 9781139455305
Category : Technology & Engineering
Languages : en
Pages : 578
Book Description
This book was first published in 2004. In many applications, images, such as ultrasonic or X-ray signals, are recorded and then analyzed with digital or optical processors in order to extract information. Such processing requires the development of algorithms of great precision and sophistication. This book presents a unified treatment of the mathematical methods that underpin the various algorithms used in remote image formation. The author begins with a review of transform and filter theory. He then discusses two- and three-dimensional Fourier transform theory, the ambiguity function, image construction and reconstruction, tomography, baseband surveillance systems, and passive systems (where the signal source might be an earthquake or a galaxy). Information-theoretic methods in image formation are also covered, as are phase errors and phase noise. Throughout the book, practical applications illustrate theoretical concepts, and there are many homework problems. The book is aimed at graduate students of electrical engineering and computer science, and practitioners in industry.

Formation of a Digital Image
Author: Robert D. Fiete
Publisher: SPIE-International Society for Optical Engineering
ISBN: 9780819489760
Category : Digital cameras
Languages : en
Pages : 0
Book Description
Creating a digital picture is so simple today that when we pick up our camera and push the button, we don't put any thought into the process that we just set into motion. The chain of events that occurs to create the photograph is called the imaging chain. The scientists and engineers who design digital cameras love to dive deep into the physics and the mathematics of the imaging chain, but discussing the imaging chain with people not well versed in this language will usually produce a blank stare or a yawn. This book discusses the concepts used to design digital cameras for people who don't want to be blinded with equations and bored with geek speak. It will help the individuals who work with camera designers and want to know, but are sometimes afraid to ask, why they keep babbling about an "MTF" or some other mysterious acronym. If you ever wondered why pinstripe suits turn psychedelic on TV or why crosses appear on pictures of stars, the imaging chain will give you the answers, and this book is for you.
