The research work presented in this report has established a new class of backscatter fiber optics probes for remote dynamic light scattering capability over a range of scattering angles from 94 degrees to 175 degrees. The fiber optic probes provide remote access to scattering systems, and can be utilized in either a noninvasive or invasive configuration. The fiber optics create an interference free data channel to inaccessible and harsh environments. Results from several studies of concentrated suspension, microemulsions, and protein systems are presented. The second part of the report describes the development of a new technology of wavefront processing within the optical fiber, that is, integrated fiber optics. Results have been very encouraging and the technology promises to have significant impact on the development of fiber optic sensors in a variety of fields ranging from environmental monitoring to optical recording, from biomedical sensing to photolithography.

Laser Light Scattering: Basic Principles and Practice, Second Edition deals with the technical aspects of laser light scattering, including the basic principles and practice. Topics covered include light scattering theory, optical mixing spectrometry, photon correlation spectroscopy, and interferometry. Experimental methods and methods of data analysis are also described. This book is comprised of eight chapters and begins with a discussion on the interrelationship between laser light scattering and other types of scattering techniques that use X-rays and neutrons, with particular reference to momentum and energy transfers as well as time-averaged and time-dependent scattered intensity. The spectrum of scattered light and a single-particle approach to time-averaged scattered intensity are considered. The following chapters focus on photoelectric detection of the scattered electric field; optical mixing spectrometers; basic equations for photon correlation spectroscopy; and the principles of Fabry-Perot interferometry. The pertinent features of the experimental aspects of laser light scattering are also outlined, together with the Laplace inversion problem. The final chapter examines polymer molecular-weight distributions in relation to particle sizing. This monograph will be of interest to physicists.

This third edition of the biomedical optics classic Tissue Optics covers the continued intensive growth in tissue optics—in particular, the field of tissue diagnostics and imaging—that has occurred since 2007. As in the first two editions, Part I describes fundamentals and basic research, and Part II presents instrumentation and medical applications. However, for the reader’s convenience, this third edition has been reorganized into 14 chapters instead of 9. The chapters covering optical coherence tomography, digital holography and interferometry, controlling optical properties of tissues, nonlinear spectroscopy, and imaging have all been substantially updated. The book is intended for researchers, teachers, and graduate and undergraduate students specializing in the physics of living systems, biomedical optics and biophotonics, laser biophysics, and applications of lasers in biomedicine. It can also be used as a textbook for courses in medical physics, medical engineering, and medical biology.

This comprehensive book set includes four volumes, covering the methods and protocols for the synthesis, fabrication, and characterization of nanomaterials. The first two books introduce the solution phase and gas synthesis approaches for nanomaterials, providing a number of most widely used protocols for each nanomaterial. An exhaustive list of nanomaterials are included, which are arranged according to the atomic number of the main element in the compound for easy search. For each material, the protocols are categorized according to the morphology of the nanostructure. A detailed reference is included in each protocol to point the readers to the source of the protocol. The third book describes many unconventional methods for the fabrication of nanostructures, including lithography and printing, self-assembly, chemical transformation, templated synthesis, electrospinning, laser induced synthesis, flame and plasma synthesis, and atomic layer deposition processes. The fourth book covers the typical methods for structural characterization of nanomaterials, including electron diffraction, electron microscopy, atomic force microscopy, scanning tunneling microscopy, X-ray diffraction, in-situ and operando X-ray techniques, X-ray absorption fine structure spectroscopy, static and dynamic light scattering, vibrational characterization methods, and NMR spectroscopy. In addition to the introduction of the basic operational principles of these tools, the book focuses explicitly on how they can be applied for analyzing nanomaterials. The handbook is a complete reference that can provide readers easily accessible information on how to synthesize and characterize nanomaterials desired for their target applications.
