Friday's OSC Community Speakers -- March 31, 2006 -- Noon -- Meinel 408/410
(1) 
Peng Su, OSC PhD candidate, will present Maximum Likelihood Estimation as a General Method of Combining Sub-Aperture Data for Interferometric Testing.  Abstract:  Interferometers accurately report the difference between two wavefronts, one from a reference surface and the other from an unknown surface. If the reference surface is near-perfect or is accurately known from some other test, then the shape of the unknown surface can be determined. We investigate the case where neither the reference surface nor the surface under test is known. By making multiple measurements where both surfaces are translated and rotated, we obtain sufficient information to reconstruct the figure of both surfaces. We use maximum likelihood estimation to obtain a 1 nm rms error. This was demonstrated for the measurement of a large flat mirror, using a smaller reference mirror that has significant shape errors.  Meanwhile I will give a brief introduction some interesting researches in our group. Diffractive solar shield, TPF, CGH aspheric certifier at caustic region…
(2)  Yi-Chun Chen, OSC PhD candidate, will present FastSPECT II: System Calibration and Small-Animal Imaging Studies.  Abstract:  FastSPECT II is a high-resolution stationary SPECT imager built with modular scintillation cameras and list-mode data-acquisition electronics.  Precise calibration of the individual detectors as well as the imaging system as a whole is the base towards satisfactory performance. This instrument possesses micro/nano-liter resolution in its low/high-magnification configuration. The capability of FastSPECT II in biomedical research is demonstrated through mouse-cardiac and mouse-femur imaging.

SPIE, OSA Announce First Goodman Book Award Winner

 

The Optical Society of America (OSA) and SPIE -- The International Society for Optical Engineering -- have announced that Harrison H. Barrett and Kyle J. Myers are the recipients of the first Joseph W. Goodman Book Writing Award for their work, Foundations of Image Science. A biennial award funded by the J.W. and H.M. Goodman Foundation, the Goodman Award recognizes a recent and outstanding book in the field of optics and photonics that has contributed significantly to research, teaching, or the optics and photonics industry. As this year’s recipients, Barrett and Myers will share the $5,000 prize and will accept the award at an upcoming OSA or SPIE meeting.

 

Described by a joint awards committee from the two societies as "a superb example of scientific and technical writing" and "likely to become the standard text for the next generations of students interested in image science," the Barrett and Myers volume explores the basic theories behind imaging systems, including the principles, mathematics, and statistics needed to understand and evaluate these systems. Published by John Wiley and Sons, the work provides a strong foundation for graduate and undergraduate students and workers in the field exploring imaging science, from satellites to medicine and beyond.

 

The selection committee, chaired by Anthony Siegman, reviewed a dozen initial nominations chose six top finalists based on recognition and merit within the community. Then, each member of the committee reviewed each finalist work, sought outside opinions, and reconvened to make a decision on the winning book.

 

"While all of the finalist works were of very high quality, committee members agreed that Foundations of Image Science was the right choice. As one of our reviewers remarked, this is a book that should be found on the bedside table of any imaging science researcher," said Anthony Siegman, selection committee chair. "On behalf of the committee, I would like to congratulate Harrison Barrett and Kyle Myers."

 

To be eligible for the award, books must meet several requirements. By the terms of the Goodman grant, books to be considered should have been recently published, and should be "authored" technical books rather than edited compilations, handbooks, reviews, or popular science books. Additionally, nominated books must be in print currently, readily available from the publisher and suppliers and must be available in English.

 

Nominations for the first Goodman Award were solicited through August 1, 2005. Any member of the optics and photonics community was able to nominate a book meeting the eligibility requirements. Nominations consisted of a 300- to 500-word narrative describing how the nominated book has "contributed significantly to research, to teaching, or to the optics and photonics industry," a short biographical note on the person making the nomination, and basic book information, including its full title, the full name of author, publisher, and date of publication.

Harrison Barrett
Regents Professor

Kyle J. Myers
OSC PhD 1985

Virendra N. Mahajan
OSC Adjunct Professor

Masud Mansuripur
OSC Professor

 

Donated jointly to OSA and SPIE and managed by the OSA Foundation, the endowment for this award was provided by a personal gift from Joseph W. and Hon Mai Goodman. The Joseph W. Goodman Book Writing Award thus becomes a new addition to the prestigious industry and professional awards already offered by OSA and SPIE.

 

When citing why he wanted to sponsor this award, Professor Goodman said, "Scientific and technical books can have an important impact on progress in optics. Recognition of important books as a substantial contribution to the field will hopefully encourage book writing by researchers and educators at all stages of their professional careers, and will benefit not only the book writers, but also the field of optics."

 

In addition to the winning work, five honorable mentions were selected from among this year's nominees, including:

  • Nonlinear Fiber Optics, 3rd edition, G.P. Agrawal, Academic Press/2001

  • Nonlinear Optics, 2nd edition, Robert W. Boyd, Academic Press/2003

  • Optical Imaging and Aberrations, Part II. Wave Diffraction Optics, Virendra N. Mahajan, SPIE Press/2001

  • Classical Optics and Its Applications, Masud Mansuripur, Cambridge Univ. Press/2001

  • Modern Lens Design, Warren Smith, McGraw-Hill and SPIE Press/2005.

 

ECE/OSC Professor Michael Marcellin Receives the 2006 Technology Innovation Award
The award recognizes faculty members who excel in technology transfer and the application of their research into marketable products.  Dr. Marcellin was selected to receive the award for his contributions to JPEG 2000, the emerging second-generation standard for image compression. He is founder of DTS AZ Research, LLC, a spinoff company specializing in applications of JPEG 2000 for digital cinema and other image applications. This new format for digital cinema is expected to be adopted industry wide by all major movie theaters in the next three to five years.   JPEG 2000 technology is already in use by more than 300 commercial products such as medical imaging.

 

 

UA Will Confer an Honorary Degree on OSC's Newest Nobel Laureate

 

Acting on a joint nomination from the College of Science and the College of Optical Sciences, UA's Faculty Senate has voted to award the honorary degree of Doctor of Science to Dr. Roy J. Glauber.  UA will recognize Dr. Glauber, an OSC adjunct faculty member for nearly twenty years and a professor at Harvard University, for his transformative work in physics and optical sciences, and  for bringing his pioneering research into applications at the University of Arizona.

 

Dr. Glauber received his 2005 Nobel Prize in physics for his contributions to the quantum theory of optical coherence -- his 1963 theoretical description of the quantum behavior of light, in which he laid the foundation for future developments in the emerging field of quantum optics.

 

UA confers honorary degrees during Commencement exercises in May and December each year.  We hope to know soon when Dr. Glauber expects to travel to the University of Arizona to receive his honorary degree.

 

 

 

Around Campus

 

March 31, 2006 -- Physics Colloquium -- 2:00 p.m. -- PAS 220
(1)  Herman Uys, Physics Department Graduate Student, will present Optimization of Phase Sensitivity in Quantum Interferometry.  Abstract: The Heisenberg limit poses a fundamental bound on the sensitivity of interferometers in the quantum regime: the phase resolution cannot exceed ~1/N, where N is the total number of particles in the system. A central challenge in theoretical studies of interferometry with quantum systems is the design of input states, Hamiltonians and measurement strategies that allow phase measurements at the Heisenberg limit. In this talk we will discuss progress towards achieving this goal by optimizing input states with variational methods. Preliminary results indicate that improved sensitivity may be achieved by minimizing moments of the phase probability distribution, of higher order than the variance.
(2)  Eric Heller, Harvard University Physics Department, will present Rays and Waves Passing Through Weakly Deflecting Random Media: Implications for Electron Flow, Starlight Refraction, and Freak- Waves in the Ocean.  Abstract: The phenomenon of small angle scattering of waves appears in many contexts, including sound wave propagation in the oceans, electron flow in two degree of freedom electron gasses, starlight twinkle, and the formation of freak oceanic waves, which occur seemingly at random in the world's oceans.  We will tie some of these phenomena together as different regimes governing weak refraction of a wave field incident on a random medium.

 

April 6, 2006 -- Special Physics Colloquium -- 2:00 p.m. -- PAS 220
Gerhard Rempe, Max-Planck Institute for Quantum Optics, will present Cold and Ultracold Molecules;  a Quantum Optical Approach.  Pierre Meystre is the faculty host.  Abstract:  Ensembles of molecules at rest have the perspective of enabling studies in so far unexplored regimes of physics and chemistry. Two complementary approaches to produce such ensembles are presently developed in several laboratories: A direct method employs static or alternating electric fields to manipulate naturally occurring dipolar molecules. An indirect method synthesizes the molecules from precooled atoms, either by photoassociation or a magnetically tunable Feshbach resonance. The talk highlights some recent achievements with both methods, including the generation of a water vapor at a translational temperature around 1 Kelvin, and the generation of rubidium molecules in an optical lattice at nanokelvin temperatures.
