Colloquium

The OSC Colloquium series is a dynamic forum for the interchange of ideas, techniques and research in all areas of optics, wherein academic scholars and industry leaders lead discussions about groundbreaking research and open the floor to questions and comments. Students, faculty members, members of the optics community and the public are all invited to attend.

Colloquium is held on Thursday in Meinel 307 each week during the academic year.

Fall 2021 & Spring 2022 Lectures

    Despite steady progress in “post-quantum” cryptography, quantum-secured communication, especially in the form of Quantum Key Distribution (QKD), remains to date  the only unconditionally secure technology to distribute secret keys. Quantum communication has effectively “...

  • Thursday, September 16, 2021 - 3:30pm - 5:00pm
    Speaker:  Dr. Ron Driggers Topic:  Advanced Infrared Systems Host:  Dr. Dalziel Wilson Visit our website for future lecture dates and speaker information: http://www.optics.arizona.edu/news-events/events/colloquium For a list of our archived lectures: http://www.optics.arizona.edu/news-events/events/colloquium/archive

    Dr. Driggers will present several topics related to advanced infrared imaging systems.  He will start with a general discussion about dual band infrared systems (third generation FLIR).  Also included are small pitch, high density focal plane systems that eliminate the need for...

  • Thursday, September 9, 2021 - 3:30pm
    Description:  Speaker:  Dr. David Brady Topic:  Neural Processing and Snapshot Compressive Imaging Host:  Dalziel Wilson Visit our website for future lecture dates and speaker information: http://www.optics.arizona.edu/news-events/events/colloquium For a list of our archived lectures: http://www.optics.arizona.edu/news-events/events/colloquium/archive

    Most imaging systems capture measurements distributed over two dimensional sensor planes. Most objects of interest are 3, 4 or 5 dimensional. (Hyperspectral images, video and volume stills are 3D, adding time, space and frequency together yields 4D or 5D data cubes). Over the past decade,...

    Speaker:  Dr. Brandon Chalifoux Topic:  Fabrication, Alignment and Testing of Ultralight Mirrors for Future X-ray Telescopes Host:  Dalziel Wilson Visit our website for future lecture dates and speaker information: http://www.optics.arizona.edu/news-events/events/colloquium For a list of our archived lectures: http://www.optics.arizona.edu/news-events/events/colloquium/archive

    Space telescopes may one day perform astronomical imaging with micro-arcsecond angular resolution in optical or even X-ray wave bands, if ultralight mirrors and structures can be fabricated and aligned with sufficient accuracy. My group’s research aims to fabricate, align, and test thin...

  • Thursday, August 26, 2021 - 3:30pm
      Speakers: Richard N. Youngworth and Dave Aikens Topic: What All Optical Scientists Should Know about (Optics) Standards Host: Dalziel Wilson Co-Host: Jose Sasian Visit our website for future lecture dates and speaker information: http://www.optics.arizona.edu/news-events/events/colloquium For a list of our archived lectures: http://www.optics.arizona.edu/news-events/events/colloquium/archive

    In this presentation we give a “crash course” into what everyone should know about how standards affect optical sciences and industry. Standards have a long rich history of successful application, including setting scientific norms like weights and measures, units, safety, providing...
