Symposium on Advanced Distributed Optical Fiber Sensor Systems for Security and Safety Applications

Organizers: Fabrizio Di Pasquale, Scuola Superiore Sant'Anna, Italy;  Morten Ibsen, University of Southampton, UK

Distributed optical fiber sensors are becoming key technologies for security and safety in strategic industrial and civil sectors such as energy production, railway and roadway transportation, and health monitoring large civil and industrial infrastructures. This symposium will focus on recent developments in distributed sensing measurement techniques, representing the most advanced progress in the field, including recent research and industrial developments.

Symposium on Functional Imaging of Visual Systems

Organizer: Jennifer Hunter, University of Rochester, USA

Understanding the process of vision is critical for our understanding of normal ocular function and its malfunction in disease. New techniques are making possible in vivo analysis of retinal function. In addition to discussing the cutting-edge optical techniques required, this symposium highlights their important scientific findings.

Symposium on the 100th Anniversary of the Bohr Atom: Niels Bohr's Nutcracker

Organizer: Charles Clark, NIST, USA

In July 1913, Niels Bohr transformed the understanding of light and matter.  Though his simple idea seems obvious to us today, it was unprecedented at the time: take the quantization rule that Planck and Einstein had used to describe the energy of light, and apply it to the mechanical motion of particles in atoms.  Since Planck’s constant h has the dimensional units of angular momentum, Bohr suggested that it provide the basis of angular momentum quantization:  L = nh / 2π , for n = 1, 2 ,3,  . . . without end.  Bohr found that this reproduced, within experimental uncertainties, the wavelengths of all 33 emission lines of atomic hydrogen that were then known, and it also showed that a number of other lines ascribed to hydrogen were actually due to He+.  It predicted additional lines in the extreme ultraviolet, which were discovered in 1914 by Theodore Lyman, and in the infrared, found in subsequent years by Brackett, Pfund and Humphries.  Bohr-like transitions have been observed in the interstellar medium for n > 1000, so his model give an accurate description of atomic line radiation acorss nearly nine decades of frequency in the electromagnetic spectrum.  Although his specific atomic model was superseded by quantum mechanics, Bohr’s basic concept endures and is often a useful guide to understanding new aspects of atomic, molecular and optical physics.

Laser Science Symposium on Undergraduate Research

Organizer: Harold Metcalf, Stony Brook Univ., USA

This special DLS annual symposium is rapidly becoming one of the most successful DLS traditions (this year's is the 12th of a series that began at the Long Beach meeting in 2001). During the past several years the number of undergraduates presenting papers has grown from only 10 to more than 40, and the talks have been of outstanding quality, some absolutely stellar. Last year's posters were outstanding as well, and generated a great deal of lively interest and on-the-spot discussion. This year's symposium will consist of afternoon poster and oral sessions. The event provides an opportunity for some of the student members of our community, who are already among the finest young scientists to be found anywhere, to present their work before an audience of their peers as well as the larger optics community. All are invited and encouraged to attend the sessions.
