Laser Speckle and Applications in Optics focuses on developments in laser speckle techniques, with emphasis on the experimental aspect of phenomena and on applications in optics. These applications include interference with scattered light, optical processing of images, and studies of surface roughness as well as displacements and deformations of diffuse objects. This book is comprised of 10 chapters and begins by reviewing the elements of diffraction theory and the properties of speckle in the image of a diffuse object. The discussion then turns to speckle in the near field and interferometry with diffuse light, along with experiments in which interference patterns are produced from photographically superimposed laterally shifted speckle patterns. The following chapters consider optical processing of images modulated by speckle; deformations and displacements of diffuse objects; speckle applications in astronomy; and surface roughness measurements. The final chapter looks at the use of laser speckle to study transparent objects; the average shape of diffuse surfaces; the transfer functions and aberrations of optical systems; and the movement of diffuse objects. This monograph will be of value to physicists and researchers as well as those interested in lasers and optics.
Publishes papers reporting on research and development in optical science and engineering and the practical applications of known optical science, engineering, and technology.
This book is the result of many years of experience of the authors in guiding physics projects. It aims to satisfy a deeply felt need to involve students and their instructors in extended experimental investigations of physical phenomena. Over fifty extended projects are described in detail, at various levels of sophistication, aimed at both the advanced high school, as well as first and second year undergraduate physics students, and their instructors. Carrying out these projects may take anything from a few days to several weeks, and in some cases months. Each project description starts with a summary of theoretical background, proceeds to outline goals and possible avenues of exploration, suggests needed instrumentation, experimental setup and data analysis, and presents typical results which can serve as guidelines for the beginner researcher. Separate parts are devoted to mechanics, electromagnetism, acoustics, optics, liquids, and thermal physics. An additional appendix suggests twenty further ideas for projects, giving a very brief description for each and providing references for pursuing them in detail. We also suggest a useful library of basic texts for each of the topics treated in the various parts.
