November 13, 2019 at 3:30pm - How you Look at it Matters: Investigations in Hyperspectral BRDF and the Role of Serendipity in Research

Carlson Auditorium, 76-1125
November 13, 2019 at 3:30pm

The increasing reliance on optical remote sensing data to provide essential data for management and modelling of our planet has opened up many opportunities for research in remote sensing.  It has also drawn attention to the complexity of that these data represent.  In this talk, Professor Coburn will address past research into the effects and impacts of spectral reflectance variability with respect to view and illumination angles.  Research into the complex nature of a surface’s spectral reflectance field has always been hampered by lack of available instruments to conduct the measurements – it has also been restricted due to larger and more pressing questions in the science.  Has the time come to begin re-writing these basic constructs?

About the Speaker

Dr. Coburn is a remote sensing scientist working in the Department of Geography at the University of Lethbridge since 2002.  With over 20 years of remote sensing experience, Dr. Coburn focuses his research efforts on the fundamental aspects of remote sensing science, with specific interests in low-cost remote sensing solutions and remote sensing instrument development.  Recently this research has involved studying the nature of surface bidirectional spectral reflectance properties.  This research has led to the development of various instruments for the sampling of surface BRDF primarily for use in understanding agricultural crops and other biological systems as well as efforts in the calibration and validation of remote sensing instruments.

October 16, 2019 at 3:30pm - Compressive Sensing for Quantum Imaging

Carlson Auditorium, 76-1125
October 16, 2019 at 3:30pm

Compressive sensing (CS) is an exciting measurement technique that effectively compresses data while it is being measured, allowing high-dimensional signals to be recovered from very few measurements. The CS approach of figuring out how to "just measure the important information" has upended traditional views on sampling and sparked enormous multidisciplinary interest over the past decade.  Remarkably, the best measurements an experimenter can use are often random.  In this talk, I will introduce the basic principles of CS and describe how it can be applied to some current problems in quantum imaging. These range from the very applied, such as how to take a picture using only one photon per pixel, to the very fundamental, such as how to characterize photonic quantum entanglement.

About the Speaker: Greg Howland is a new assistant professor in the School of Physics and Astronomy at RIT. Previously, he worked as a Postdoctoral Researcher in Prof. Stefan Preble’s Integrated Photonics Group at RIT and was a research physicist at the Air Force Research Laboratory in Rome, NY in the Quantum Information Science group. He received his PhD in Physics from the University of Rochester in 2014. His research interests are in quantum information and quantum optical technologies in bulk optics and photonic integrated circuits

September 25, 2019 at 3:30pm - Tiny Mirrors and Big Pictures: Digital micromirror device development and applications

Carlson Auditorium, 76-1125
September 25, 2019 at 3:30pm


DLP® technology has been widely used in various display products since it was introduced to the market in 1996 by Texas Instruments. It has revolutionized the century-old movie industry by replacing the traditional film with the digital display technology. The heart of the DLP® technology is the digital micromirror device (DMD), an optical microelectromechanical system, which features an addressable array of up to 8 million microscopic mirrors. This presentation will cover the design, fabrication, packaging, characterization, and reliability of the DMDs. I will discuss the challenges and solutions of several major milestones of DMD development from the micromirror design and operation point of view. Applications of the DMD in nontraditional display technologies, such as compressive line sensing-based underwater imaging technology, will be shared with the audience.

About the Speaker

Dr. Cuiling (Sue) Gong joined the Digital Micromirror Device (DMD) development team at Texas Instruments in 2000. She was the core designer of three generations of DMD pixels that had enabled a variety of DLP® products in the market including pico-projectors, projectors in classrooms, conference rooms, and movie theaters. She also conducted R&D work on micro-scale vibration based piezoelectric energy harvesting technology for autonomous wireless sensor networks. She has 8 issued US patents. In 2011 she joined the faculty of the College of Science and Engineering at Texas Christian University in Fort Worth, Texas.

September 18, 2019 at 3:30pm - Hyperspectral Imaging Applications and Novel Sensor Development

Carlson Auditorium, 76-1125
September 18, 2019 at 3:30pm


This seminar presents an application-driven approach to novel hyperspectral imaging sensor design. Brief summaries of hyperspectral imaging modalities and their relative performance are presented. Spectro-radiometric signature models are then discussed in the context of sensor and detection algorithm requirements definition. Specifically, how do we design a hyperspectral sensor with sufficient sensitivity and specificity to meet the application requirements? How do we choose the optimal sensor modality given a concept of operation or deployment? What are the size, weight, power and cost considerations? This design process is then illustrated in a discussion of two prototype systems: a UAS-borne visible/near infrared-shortwave infrared hyperspectral imager for vegetation trait mapping, and a longwave infrared hyperspectral imager employing compressive sensing and a single pixel architecture for chemical plume imaging.

About the speaker

September 11, 2019 at 3:30am - The Anomalous Origin of Polymer Enhanced Oil Recovery

Carlson Auditorium, 76-1125
September 11, 2019 at 3:30am

Abstract: Polymer flooding is one of the most economically viable methods for enhanced oil recovery. It is typically used in reservoirs where recovery of oil by water injection declines. Polymer enhanced oil recovery is achieved by flowing a small volume of a polymer solution into the reservoir, followed by more water. Although polymer flooding is primarily developed for increasing the viscosity of the displacing fluid to match that of the oil, enhanced recovery is observed for oils as much as two orders of magnitude more viscous than the polymer solution with surprisingly significant recovery during the second water. To understand this behavior, we use confocal microscopy and particle tracking to determine the velocities of the displacing fluid around trapped oil in a 3D micromodel of porous medium. We find that some polymer is retained in the medium resulting in reduction in the permeability and large and heterogenous changes in the local fluid velocities with as much as an order of magnitude increase in some pores, leading to further mobilization of trapped oil.

About the Speaker: Shima Parsa is an assistant professor of Physics at Rochester Institute of Technology. She has joined RIT in 2019 after her postdoctoral fellowship at Harvard University, where she studied dynamics of multiphase flow in porous media with applications in oil recovery. Shima completed her PhD in Physics at Wesleyan University, where she studied the dynamics of anisotropic particles in turbulence. She is an experimental Physicist with a passion for developing observational and imaging techniques to study Soft Matter. Her research at RIT spans from microfluidics to large scale sedimentation in river with a focus on understanding the fundamental physics of interaction between many bodies mediated by fluid flow.
