The measurement and characterisation of surface topography is crucial to modern manufacturing industry. The control of areal surface structure allows a manufacturer to radically alter the ...functionality of a part. Examples include structuring to effect fluidics, optics, tribology, aerodynamics and biology. To control such manufacturing methods requires measurement strategies. There is now a large range of new optical techniques on the market, or being developed in academia, that can measure areal surface topography. Each method has its strong points and limitations. The book starts with introductory chapters on optical instruments, their common language, generic features and limitations, and their calibration. Each type of modern optical instrument is described (in a common format) by an expert in the field. The book is intended for both industrial and academic scientists and engineers, and will be useful for undergraduate and postgraduate studies.
The purpose of this study is to determine to what extent students' problem solving skill on geometric optical topic. The method used was survey on 34 students of XI graders at SMA Negeri 9 Malang who ...have obtained optical geometry lesson. The average score of problem solving skill of students was 61,12, with the highest score was 184 and the lowest score was 34. The result of the research shows that students problem solving ability in the novice category is bigger than expert category,thus it needs to implement learning which improves students problem solving ability. Abstrak: Tujuan dari penelitian ini adalah untuk mengetahui sejauh mana kemampaun pemecahan masalah siswa pada materi optika geometri. Metode yang digunakan dengan survei pada 34 siswa kelas XI SMA Negeri 9 Malang yang telah memperoleh pelajaran optika geometri. Nilai rata-rata kemampuan pemecahan masalah siswa sebesar 61,12 dengan nilai tertinggi adalah 184 dan nilai terendah 34. Hasil penelitian menunjukkan bahwa kemampuan pemecahan masalah siswa dalam kategori novice lebih besar daripada kategori expert, sehingga perlu diterapan pembelajaran untuk meningkatkan kemampuan pemecahan masalah siswa.

This book discusses a new class of photonic devices, known as surface plasmon nanophotonic structures. The book highlights several exciting new discoveries, while providing a clear discussion of the ...underlying physics, the nanofabrication issues, and the materials considerations involved in designing plasmonic devices with new functionality. Chapters written by the leaders in the field of plasmonics provide a solid background to each topic.
Fiber-optic communication systems have revolutionized our telecommunication infrastructures - currently, almost all telephone land-line, cellular, and internet communications must travel via some ...form of optical fibers. In these transmission systems, neither the phase nor frequency of the optical signal carries information - only the intensity of the signal is used. To transmit more information in a single optical carrier, the phase of the optical carrier must be explored. As a result, there is renewed interest in phase-modulated optical communications, mainly in direct-detection DPSK signals for long-haul optical communication systems. When optical amplifiers are used to maintain certain signal level among the fiber link, the system is limited by amplifier noises and fiber nonlinearities. Phase-Modulated Optical Communication Systems surveys this newly popular area, covering the following topics: - The transmitter and receiver for phase-modulated coherent lightwave systems - Method for performance analysis of phase-modulated optical signals - Direct-detection DPSK signal with fiber nonlinearities, degraded by nonlinear phase noise and intrachannel effects - Wavelength-division-multiplexed direct-detection DPSK signals - Multi-level phase-modulated optical signals, such as the four-phase DQPSK signal. Graduate students, professional engineers, and researchers will all benefit from this updated treatment of an important topic in the optical communications field.
This is the first comprehensive book on the engineering of diamond optical devices.

The authors believe that photonic crystal fibers can revolutionize the field of guided optics and its applications.
This book is an indispensable collection of key optical measurement techniques essential for developing and characterizing today's photonic devices and fiber optic systems. Provided are comprehensive ...and systematic descriptions of various fiber optic measurement methods with the emphasis on the understanding of optoelectronic signal processing methodologies, helping the reader to weigh up the pros and cons of each technique and establish their suitability for the task at hand.
Polymer/metals nanocomposite films were investigated from aqueous solutions of polyvinyl alcohol (PVA)/acrylic acid (AAc) using UV radiation. The formation of metal nanoparticles (NPs) was ...characterized by transmission electron microscopy (TEM), Fourier-transform infrared spectrometry (FTIR) and UV-vis spectroscopy. It was found that UV radiation induced the reduction of the metal ions in the polymer matrix into metal nanoparticles. The electrical properties and the anti-microbial efficiency were carried out for the prepared compositions. The maximum AC conductivity was observed in the composites containing Ag NPs. Finally, a green method has been suggested for the development of conductive nano polymer/metal composites that can be used in biomedical applications.
"Scanning and stationary-beam electron microscopes have become an indespensible tool for both research and routine evaluation in materials science, the semiconductor industry, nanotechnology and the ...biological, forensic, and medical sciences. This book provides an introduction to the theory and current practice of electron microscopy, aimed primarily at undergraduates who need to learn how the basic principles of physics are applied in an important area of science and technology that has contributed greatly to our knowledge of life processes and ""inner space."" However, it will be equally valuable for technologists who make use of electron microscopes and for graduate students, university teachers and researchers who need a concise text that deals with the basic principles of microscopy. Less technical but broader in scope than other microscopy textbooks, Physical Principles of Electron Microscopy is appropriate for undergraduates and technologists with limited mathematical training."
