English | January 24, 2024 | ISBN: 3031452445 | 90 pages | MOBI | 7.09 Mb
This book focuses on advanced optical properties and applications of tellurite glasses and tellurite glasses doped with rare-earth nanoparticles. The initial chapter presents the current state of the art in tellurite glass development, focusing on those compositions doped with nanoparticles based on rare-earth elements such as neodymium and erbium. The book then discusses various linear and nonlinear optical properties (e.g., refractive index, absorption, optical susceptibility) of these glasses in the visible and ultraviolet spectral regions. Finally, it looks at a selection of recent technological applications of doped tellurite glasses, such as highly efficient laser glass, novel temperature sensors, and advanced optical fiber material. Featuring comprehensive and up-to-date data sets, along with a topical discussion of promising new areas of application, this book is particularly suitable for researchers and industry professionals working in the field of glass manufacturing foroptics and laser applications.

English | 2022 | ISBN: 9811948224, 9811948259 | PDF | pages: 474 | 17.6 mb
This book presents the key technologies of coherent optical wireless communication, covers topics such as beam coupling, signal optical polarization control and distorted wavefront correction. It discusses the principle of coherent optical communication and heterodyne detection conditions. In this book, the array coupling receiving technology and large aperture coupling technology are introduced to realize the spatial optical fiber coupling; simulated annealing algorithm, particle swarm optimization algorithm and SPO algorithm are used to control the polarization state of the signal beam; and the correction of distorted wavefront of the signal beam by adaptive optics technology and wavefront sensorless adaptive optics technology are analyzed, and the influence of beam mode on coherent detection performance is elaborated. Both theoretical deduction and experimental results are included in this book, which can help readers further understand the theoretical knowledge.

Free Download Michael A. DiSpezio, "Optical Illusion Experiments"
English | ISBN: 0806966297 | 2001 | 128 pages | PDF | 8 MB
Be a scientist-and a magician-all at once! With just a little practice, you’ll amaze people with fool-the-eye illusions that are also clever science experiments. Even more important, you’ll understand completely how they work, and why things appear to be different than they really are. Using the most ordinary household materials, make a poker chip glow with a ghostlike blur. Shine a flashlight so it leaves a trail of light. Draw shark fins in a book, then watch them swim. Watch as an "X" disappears from a piece of paper. Turn green boxes red, then green again. Or see what else you can do!

English | ISBN: 0806966416 | 2001 | 80 pages | PDF | 7 MB
Every image in this follow-up to Optical Illusion Magic is out to trick your perception with afterimages, visual "traps," and distorted views. Sometimes you’ll have to shift the page to see the magic; in other illusions, pattern and shape make all the difference, producing spirals where none really exist.
