DIRS Meeting

Speaker #1:
Improvements to an Earth Observing Statistical Performance Model

Runchen Zhao
Ph.D. Student
Chester F. Carlson Center for Imaging Science, RIT
Advisor: Dr. Emmett Ientilucci

In this presentation, we will describe an improved full-spectrum spectral imaging model with longwave infrared (LWIR) temperature/emissivity separation capability and advanced detection algorithm (i.e., ACE). The model can be used for parameter trade-off studies, which will be briefly discussed. This model uses first- and second-order statistics of surface spectral reflectances/emissivities and temperature variations to describe a scene, for example. These statistics are propagated through the system including adding atmospheric effects, sensor noise and applying processing approaches such as target detection. System performance is addressed using a metric such as the receiver operating characteristic (ROC) curve.

Speaker Bio:
Runchen Zhao received his B.S. in applied physics from Xidian University in 2011, and M.S. in material science from the Rochester Institute of Technology in 2014. He is currently a Ph.D. student working under Dr. Ientilucci in the Digital Imaging and Remote Sensing Laboratory, Chester F. Carlson Center for Imaging Science, Rochester Institute of Technology. His current research involves end-to-end LWIR simulations consisting of statistical atmospheric compensation and statistical detection algorithm development.


Speaker #2:
Mirror-based Vicarious Calibration of Airborne Imagers

David Conran
Ph.D. Student
Chester F. Carlson Center for Imaging Science, RIT
Advisor: Dr. Emmett Ientilucci

FLARE is a Labsphere/Raytheon project to calibrate the world by using the SPecular Array Radiometric Calibration (SPARC) method. All airborne imagers with GSD’s less than 100m can be fully calibrated for At-Senor Radiance and/or At-surface Reflectance while simultaneously accounting for path radiance and scattering within the atmosphere with uncertainties on the order of 3-4% at the sensor. This method uses the exo-atmospheric solar spectral irradiance for traceability to absolute units and can be deployed anywhere on Earth. This talk with discuss the radiometry and applications of the SPARC targets used in the FLARE project.

Speaker Bio:
David Conran is a second year Ph.D student working with Dr. Ientilucci on general radiometric calibration procedures and uncertainty analysis. David currently manages the day-to-day operations of the Radiometric Calibration Lab where procedures and standards are being developed for an absolute radiometric calibration enterprise at RIT. He received his B.S. in Astrophysics and Astronomy from the Pennsylvania State University in May of 2018.

Intended Audience:
All are welcome.
