A bonus added to SPIE membership in 2008 is free access to a paper selected monthly from the SPIE Digital Library, the world's largest library of scientific knowledge in optics, photonics, and imaging. A free paper is just one of the many ways SPIE helps members collect new ideas for taking optics and photonics technology to market.
SPIE has selected papers recently published on the SPIE Digital Library that are on topics of interest to a broad cross-section of members. These papers are available free to members, primarily through the monthly SPIE Member E-Newsletter, for up to six months.
With more than 250,000 papers in its collections, the SPIE Digital Library is among the most widely cited publications by technology companies submitting patent applications. Journal articles, editor-reviewed conference proceedings, and other research papers provide access to the most current technical research, analysis and solutions. The SPIE Digital Library covers all the major work in this field of optics and photonics from 1990 to the present.
The free articles made available exclusively to members include:
- A study by a group from Berkeley's Department of Electrical Engineering on recent advances in optoelectronic tweezers (OET). Recent advances include the characterization of optoelectronic tweezers operational regimes, manipulation of biological samples such as cells in high conductivity physiological solutions with translation speeds higher than 30 µm/s, manipulation of air bubbles in silicone oil media with speeds up to 1.5 mm/s, and an exploration of the limits on the smallest particle that OET is capable of trapping. The authors' study illustrates the new functionalities being provided by advances in OET as an optofluidic system. Access this invited paper from the proceedings of SPIE Europe Photonics Europe 2008.
- An invited paper by Anthony F.J. Levi of the University of Southern California presented at SPIE Photonics West in January 2008, which advocates for a new approach to creating devices using nanoscience. In Frontiers in Device Engineering: Synthesis for Non-Intuitive Design, Levi shows that traditional approaches consist of recreating previous electronic and photonic devices using nanotechnology. But he also shows how this approach ignores the new opportunities that nanotechnology makes available. Levi provides a new methodology for understanding these opportunities. In order to utilize the "true potential" of nanotechnology, Levi explains, "What is needed is a systematic experimental and theoretical approach that results in the efficient discovery of atom- molecular- and macro-molecular-based configurations" that exhibit the desired, user-specified functionality. A.F.J. Levi's paper.
- Eric Udd's paper on fiber optic grating sensors, which reviews the construction of fiber optic grating sensors that are capable of measuring two or more environmental parameters simultaneously. Udd, owner and president of Columbia Gorge Research explains that this "results in the realization of a host of new sensing possibilities including multi-dimensional strain, shear strain in bond lines, imaging of damage in composite materials via "strain imaging" and fiber grating sensors that are capable of compensating for temperature while measuring pressure, corrosion and other environmental effects." Access Eric Udd's paper.
- A journal article co-authored by Adam M. Zysk, Freddy T Nguyen, Amy L. Marks, and Stephen A Boppart that details the process optical coherence tomography (OCT) has taken from being developed for use in laboratories, to being applied in a clinical setting, and back to the lab bench again. The authors have observed that this cyclical process has ensured the rapid development of OCT technology. Additionally, the authors show in this article from the Journal of Biomedical Optics that this unique model carries important implications for the translation of biomedical optics to the patient's bedside. Access this article about OCT.
- An account by Christopher J. Stolz of the construction of the National Ignition Facility, which will be the world's largest optical system. Stolz analyzes the methods used to produce the 192-beam fusion laser more quickly and at a reduced cost for the construction of the facility. The paper shows that, as a result, more advanced fabrication technologies have been developed than what has been used to create fusion lasers in the past. Access this paper by Christopher Stolz.
- A review by Warren D. Reynolds, CEO of Eco-Engineers, Inc., of the transition from the 20th century as the "Age of the Petroleum Economy" to the 21st century as "the Age of the Solar-Hydrogen Economy." Reynolds lists three major factors as the driving forces of the Solar-Hydrogen Economy: the environment, the economy, and national security. The author also discusses a 24-hour/day 200 MWe solar-hydrogen power plant for the United States as well as the projected growth in the Solar-Hydrogen Economy through 2045. Access Warren Reynold's paper.
