Download or read book Some Preliminary Calculations on the Direct Transmission of Light Through a Plane Water Surface and Its Return by a Submerged Retroreflector written by R. L. Denningham and published by . This book was released on 1967 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: When light passes through a plane water surface from the atmosphere and is reflected by a retroreflector having a flat glass entrance face, reflective losses occur at two interfaces: air-water and water-glass. In the report the general problem of computing round-trip transmission values for arbitrary relative orientations of the incidence planes at the water surface and the retrosurface is solved, and numerical computations of the effective transmissions for unpolarized light are presented for the coplanar case. The transmission depends on the angle between the direction of incident light and the normal to the interface and on the degree of polarization. The results show that high transmissions can exist, provided the light does not graze either the water surface or the entrance face of the retroreflector. When the light is incident normal to the water surface, the round-trip transmission is approximately 95 percent even when the incident angle at the retroreflector face is as much as 30 degrees; but this value is decreased by about one-half when the incident angle at the retroreflector is 80 degrees. Similarly, the transmission remains high when the direction of incident light at the water surface is inclined up to 30 degrees to the normal. Even when this angle is 85 degrees, the transmission is about 20 percent, provided the retroreflector is inclined properly. Light incident on the water surface from a given direction will be returned most efficiently by a retroreflector when its face is normal to the direction of the light after being refracted at the water surface.

Download or read book Transmission of Ruby Laser Light Through Water written by J. A. Curcio and published by . This book was released on 1963 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The attenuation coefficients of filtered Potomac River water were measured at the ruby laser wave length, 6943A, and at three wavelengths in the green region of the spectrum where the attenua tion is near the minimum. The tests were con ducted in situ at the David Taylor Model Basin. The path of the light beam, which was at a depth of 2.2 m, was varied from 6 to 36 m in the laser light observations and from 15 to 73 m for the green light observations. Narrow-band filters were used to restrict the passbad of the system, and the field of view of the receiver was limited to 1.2 degrees. The attenuation coef ficient obtained at 6943A was .00545/cm and the value obtained at 4900A was .00086/cm. Evidence was found for some small particle scattering. As an underwater light source, the ruby laser is severely handicapped by the fact that its emission occurs at a wavelength which is highly attenuated by water. (Author).

Download or read book Environmental Pollution and Control written by J. Jeffrey Peirce and published by Butterworth-Heinemann. This book was released on 1998-01-15 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex environmental problems are often reduced to an inappropriate level of simplicity. While this book does not seek to present a comprehensive scientific and technical coverage of all aspects of the subject matter, it makes the issues, ideas, and language of environmental engineering accessible and understandable to the nontechnical reader.Improvements introduced in the fourth edition include a complete rewrite of the chapters dealing with risk assessment and ethics, the introduction of new theories of radiation damage, inclusion of environmental disasters like Chernobyl and Bhopal, and general updating of all the content, specifically that on radioactive waste.Since this book was first published in 1972, several generations of students have become environmentally aware and conscious of their responsibilities to the planet earth. Many of these environmental pioneers are now teaching in colleges and universities, and have in their classes students with the same sense of dedication and resolve that they themselves brought to the discipline. In those days, it was sometimes difficult to explain what indeed environmental science or engineering was, and why the development of these fields was so important to the future of the earth and to human civilization. Today there is no question that the human species has the capability of destroying its collective home, and that we have indeed taken major steps toward doing exactly that.And yet, while, a lot has changed in a generation, much has not. We still have air pollution; we still contaminate our water supplies; we still dispose of hazardous materials improperly; we still destroy natural habitats as if no other species mattered. And worst of all, we still continue to populate the earth at an alarming rate. There is still a need for this book, and for the college and university courses that use it as a text, and perhaps this need is more acute now than it was several decades ago. Although the battle to preserve the environment is still raging, some of the rules have changed. We now must take into account risk to humans, and be able to manipulate concepts of risk management. With increasing population, and fewer alternatives to waste disposal, this problem is intensified. Environmental laws have changed, and will no doubt continue to evolve. Attitudes toward the environment are often couched in what has become known as the environmental ethic. Finally, the environmental movement has become powerful politically, and environmentalism can be made to serve a political agenda.In revising this book, we have attempted to incorporate the evolving nature of environmental sciences and engineering by adding chapters as necessary and eliminating material that is less germane to today's students. We have nevertheless maintained the essential feature of this book -- to package the more important aspects of environmental engineering science and technology in an organized manner and present this mainly technical material to a nonengineering audience.This book has been used as a text in courses which require no prerequisites, although a high school knowledge of chemistry is important. A knowledge of college level algebra is also useful, but calculus is not required for the understanding of the technical and scientific concepts.We do not intend for this book to be scientifically and technically complete. In fact, many complex environmental problems have been simplified to the threshold of pain for many engineers and scientists. Our objective, however, is not to impress nontechnical students with the rigors and complexities of pollution control technology but rather to make some of the language and ideas of environmental engineering and science more understandable.

Download or read book Light and Photosynthesis in Aquatic Ecosystems written by John T. O. Kirk and published by Cambridge University Press. This book was released on 1994-04-21 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: Penetration of light into aquatic ecosystems is greatly affected by the absorption and scattering processes that take place within the water. Thus within any water body, the intensity and colour of the light field changes greatly with depth and this has a marked influence on both the total productivity of, and the kinds of plant that predominate in, the ecosystem. This study presents an integrated and coherent treatment of the key role of light in aquatic ecosystems. It ranges from the physics of light transmission within water, through the biochemistry and physiology of aquatic photosynthesis, to the ecological relationships which depend on the underwater light climate.
Download or read book Transmission of Green Laser Light 5300a Through Water written by D. E. MATLACK and published by . This book was released on 1964 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extinction coefficient of filtered Potomac River water was measured at the frequency doubled neodymium 'green laser' wavelength of 5300A. Measurements were conducted in situ at the David Taylor Model Basin (DTMB) in a cooperative program with the Naval Research Laboratory (NRL). Extinction coefficients of 0.097, 0.104 and 0.119/m were measured on 4, 5 and 8 June 1964, respectively. The increase in attenuation with time is confirmed by filtered arc light measurements made by the NRL and is attributed to contamination of the water after the basin filtration system was turned off. Scattering experiments indicate that the aureole effect for the highly collimated laser beam was small over the 200 meter range of the measurements. (Author).
Download or read book Image Processing in Optical Coherence Tomography Using Matlab written by Robert Koprowski and published by Robert Koprowski. This book was released on 2011 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the results of the creation of methods for ophthalmologists support in OCT images automated analysis. These methods, like the application developed on their basis, are used during routine examinations carried out in hospital. The monograph comprises proposals of new and also of known algorithms, modified by authors, for image analysis and processing, presented on the basis of example of Matlab environment with Image Processing tools. The results are not only obtained fully automatically, but also repeatable, providing doctors with quantitative information on the degree of pathology occurring in the patient. In this case the anterior and posterior eye segment is analysed, e.g. the measurement of the filtration angle or individual layers thickness. To introduce the Readers to subtleties related to the implementation of selected fragments of algorithms, the notation of some of them in the Matlab environment has been given. The presented source code is shown only in the form of example of implementable selected algorithm. In no way we impose here the method of resolution on the Reader and we only provide the confirmation of a possibility of its practical implementation.
