• Departmental Colloquium Nov 1, 2018

  What are CubeSats? A look at how UGA is advancing the new realm of space research

  

  Guest: Caleb Adams, Katie Summey & Nicholas Heavner, Department of Physics and Astronomy, UGA
  Thursday, November 1, 2018 3:30 pm - 4:30 pm
  Location: Physics Auditorium (202)

  The Small Satellite Research Laboratory began in 2016 with the funding of two small satellite, also known as CubeSats, missions through a joint effort between faculty and undergraduate students. Caleb Adams led the lab from the beginning as an undergraduate and now a graduate student. He will discuss the specifics and needs of CubeSats in the new era of space exploration as well as our current Air Force Research Lab (AFRL) funded mission. The AFRL mission, named the Multi-view Onboard Computational Imager (MOCI), will change the way data is used in the space environment by advancing high performance computing capabilities. Katie Summey, a Computer Science Engineering Major, will describe the goals of our NASA funded project, the Spectral Ocean Color (SPOC) mission and focus on the unique optical setup required for such a small space based imager. Finally Nicholas Heavner, a Mechanical Engineering and Physics/Astronomy student, will cover the thermal issues that arise on such a small platforms and the methods used to mitigate this risk.

• Observatory Open House Nov 2, 2018

  Observatory Viewing

  

  Guest: Dr. Loris Magnani and Dr. Scott Shaw, UGA Department of Physics and Astronomy
  Friday, November 2, 2018 8:00 pm - 9:00 pm
  Location: UGA Observatory (4th floor Physics Building)

  iCal

  We will be having another public viewing on November 2, 2018.

  If the skies are clear, we will be looking at Saturn and Mars.

  Because of the limited space in the dome, you must have a reservation to come to this showing. We will begin taking reservations for this viewing on Tuesday, August 14th at 12:00pm. Click here to make a reservation.

  The observatory is located at the top of the Physics building. To get to the observatory take the elevator to the 4th floor. A guide will meet you on the 4th floor and direct your group to the stairway that leads to the observatory. As the weather can be unpredictable, we might not know whether a viewing will be possible until shortly before the event begins.

  If you need more information please call 706-542-2485.

• Departmental Colloquium Nov 8, 2018

  Optical Spectroscopy for Sensing and Imaging Applications

  

  Guest: Prof. Zhiwen Liu, Department of Electrical Engineering, The Pennsylvania State University
  Thursday, November 8, 2018 3:30 pm - 4:30 pm
  Location: Physics Auditorium (202)

  In this talk I will discuss our work on the application of optical spectroscopy to sensing and label-free imaging. A compact spectrometer is developed by using a G-Fresnel device with dual functionalities of focusing and wavelength dispersion, which can enable miniaturization of optical spectrometers and thus the integration of optical spectroscopy with smartphone technology. The use of smartphone based diffuse reflectance spectroscopy for hemoglobin sensing and for detecting plant d i s e a s e s w i l l b e d i s c u s s e d . M e r g i n g t h e c ap a b i l i t i e s o f v i b r a t i o n a l spectroscopy and holography can lead to new opportunities for bio- imaging. The vibrational response of target molecules provides a means for chemical contrast, while holographic detection captures both the amplitude and the phase of a complex signal field to enable label-free three-dimensional imaging. Vibrational spectroscopic holography, including holographic coherent anti-Stokes Raman scattering imaging and holographic sum frequency generation imaging, will be discussed.

• Applied Physics Seminar Nov 9, 2018

  Smartphone based optical spectroscopy

  

  Guest: Prof. Zhiwen Liu, Department of Electrical Engineering, The Pennsylvania State University
  Friday, November 9, 2018 12:20 pm - 1:20 pm
  Location: CSP Conference Room (322)

  Smartphone based optical sensing has recently attracted a lot of interests. The wide availability of smartphones and their advanced computational and wireless communicational capabilities coupled with chemical sensing abilities of optical techniques provide intriguing possibilities of “lab on a palm.” In this talk I will present our work on smartphone based optical spectroscopy. Compact spectrometers are developed by using a G-Fresnel device with the dual functionalities of focusing and wavelength dispersion, which can enable miniaturization of optical spectrometers and thus the integration of optical spectroscopy with smartphone technology. The fabrication and characterizations of the smartphone based spectrometer are presented. I will discuss potential applications of smartphone based optical spectroscopy. Specifically, the use of smartphone based diffuse reflectance spectroscopy for hemoglobin sensing and for detecting plant diseases will be discussed.
