Students | Alumni | Industrial Affiliates | Faculty | Watt's Happening | Employment
Today's Colloquium: 3:30 p.m. Meinel 307
Art Gmitro, University of Arizona Department of Radiology and College of Optical Sciences, will present A Tale of Two Projects. Stanley Pau is the host. Abstract: This talk will describe recent progress on two research projects in the Biomedical Imaging Laboratory. One project is aimed at the development, clinical demonstration, and validation of a confocal microendoscope for real-time in vivo optical biopsy. The other project involves development of multi-modality optical and magnetic resonance imaging of window chambers for studies of cancer and vascular biology.

Special Presentation: April 14, 11:15 a.m. Meinel 821
Biophotonics Faculty Candidate Daniel l. Marks, University of Illinois Biophotonics Imaging Laboratory, will present Interferometric Synthetic Aperture Microscopy: Tomographic Computer Imaging for Scanned Microscopy. Abstract: Three-dimensional image formation in microscopy is greatly enhanced by the use of computed imaging techniques. Methods such as optical coherence tomography utilize interferometric ranging, but do not typically apply computed imaging methods and therefore must scan the focus to acquire volumetric data. Inteferometric Synthetic Aperture Microscopy is a method of computing three-dimensional volumetric reconstructions from interferometric ranging data. ISAM signal processing methods are similar to the Fourier migration methods of seismology and Fourier reconstruction methods of synthetic aperture radar, and ISAM signal processing methods benefit from innovations in these areas. The principles of ISAM are reviewed and the applications of various ISAM solutions to various optical coherence ranging instruments is explored.
Bio: Daniel Marks is a Research Scientist at the Biophotonics Laboratory of the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign. He received his PhD in Electrical Engineering from University of Illinois at Urbana-Champaign in January 2001. Dan studies the mathematics, design, and implementation of advanced biomedical and nanotechnological imaging instruments that combine optical design with signal processing to optimize sensing of particular structural and molecular properties.

Next Week's Colloquium: 3:30 p.m. Meinel 307
Shibin Jiang, NP Photonics and an OSC Adjunct Research Professor, will present Multi-Component Specialty Glass Fiber Lasers. Masud Mansuripur is the host. Abstract: Fiber lasers have attracted significant attention in last several years because of many technology breakthroughs and commercial business successes. Most fiber lasers use rare-earth ions doped silica fibers as the gain media. However, in many cases silica fiber is not the ideal host. Multi-component specialty glass fibers are good alternatives because of their unique features such as low co-operative up-conversion coefficient, large mode field diameter, and short active fiber length. In this presentation, I will present highly erbium and ytterbium doped phosphate glass fibers for narrow linewidth single frequency fiber lasers near 1.5 and 1 microns, and thulium doped germanate glass fiber 2 micron fiber lasers with slope efficiency great than 70%. Brillouin fiber laser, Brillouin based fiber sensing, and potential application for wireless-over-fiber will be discussed. THz and GHz generation using Q-switched high power fiber lasers will also be described in this presentation.

Last week's photo of Steve Jacobs' beautiful sun clock on Kitt Peak raised a number of questions and deserves some clarification.
In Steve's own words:
"Inspired by the sunshine hours (Campbell-Stokes) recorder at the Royal Stockholm Observatory, Professor Jacobs designed a similar configuration to tell time at Kitt Peak National Observatory. When the sun moves over Stockholm, a beautiful polished glass sphere burns a record of the sunny hours on a paper that’s replaced every day. In Jacobs’ version, the central focal spot forms an image on a ground glass that is marked off in hours.
"Many lessons were learned along the way. The first surprise is shown in Fig. 1 where in addition to the central focal spot we see two white rings. The explanation of the rings was found by Steve Johnston’s ray tracing, shown in Fig. 2. The next surprise was that the partly transmitting metal attenuators* couldn’t stand the heat, and the Pyrex focal surface was destroyed. The current redesign locates the chromium attenuator on the sphere’s surface, farther from the hot spot.
"The original configuration kept being destroyed by focused sunlight, and finally when I found a durable coating it was destroyed by "a sonic boom" !? Rather than try again to reproduce the special attenuating coating I changed the design so that the coating is no longer critical. E.g. I coated the sphere itself, in order to distance the coating from the hot spot. (See Fig. 4 ).
"It will be installed on Kitt Peak later this month.
"Good luck to us!"
* "Attenuation is needed not only because it’s no fun looking toward the sun, but to attenuate a bright caustic of rays that form a distraction just beyond the central focal spot."
