Free Download Optical Polymer Waveguides: From the Design to the Final 3D-Opto Mechatronic Integrated Device by Jörg Franke, Ludger Overmeyer, Norbert Lindlein, Karlheinz Bock, Stefan Kaierle, Oliver Suttmann, Klaus-Jürgen Wolter

Light signals in optical waveguides can be used to transmit very large amounts of data quickly and largely without interference. In the industrial and infrastructural sectors, e.g. in the automotive and aerospace industries, the demand to further exploit this potential is therefore increasing. Which technologies can be used to effectively integrate systems that transmit data by means of light into existing components? This is a central question for current research. So far, there have been some technical limitations in this regard. For example, it is difficult to couple the signal of an optical waveguide to other optical waveguides without interruption. There is also a lack of suitable fabrication technologies for three-dimensional waveguides, as well as design and simulation environments for 3D opto-MID. This book addresses these and other challenges.

Free Download Swept-source Optical Coherence Tomography: A Color Atlas (Second Edition)
English | 2018 | ISBN: 9813271779 | 101 Pages | PDF (True) | 57 MB
This book is written for retinal specialists and clinicians with a special interest in retinal diseases. It presents a collection of images and brief annotations of the microstructures of both the normal and diseased eye captured on swept source optical coherence tomography.The swept-source OCT is a relatively new form of imaging and is able to capture structures and details which previous generations of OCT machines cannot. This type of imaging represents the forefront in ocular imaging. This second edition includes a new chapter on optic nerve conditions and more cases on eye conditions that were imaged with the SS-OCT. It also showcases the use of swept-source OCT for OCT angiography.

Free Download Optical Properties of Wood: Measurement Methods and Result Evaluations
English | 2024 | ISBN: 3031469054 | 549 Pages | PDF EPUB (True) | 50 MB
This book describes all optical properties of wooden materials, including definitions and measurement methods of optical parameters such as absorbance, diffuse and specular reflectance, colour and gloss. Basic knowledge regarding the reflectance measurement in the ultraviolet, visible, near- and middle infrared radiation ranges is also discussed. It examines conducting correct optical measurements, as well as introduces the validity limits of the individual methods. Steaming as an environmental-friendly colour modification process is introduced by the description of the steaming properties of eight species. Steaming schedules for wood-working industry are suggested to create optimum colour modification. Natural and artificial aspects of photodegradation are monitored by studying the colour change and using infrared reflectance spectrum measurement. The effect of influencing parameters such as temperature, relative air humidity and leaching effect of rain is also discussed. Combined effects of heat and light on the optical properties of wood in all possible combinations are presented. The book helps wood researchers and Ph.D. students perform correct and repeatable optical measurements and evaluations in order to draw the right conclusions.
