THz Imaging: What You See and What You Don't

Back to Seminar Archive...

Friday, November 8, Giedt 1003, 12:10pm-1:00pm

Speaker: Peter Siegel
Caltech

Host: Professor Jane Gu

Abstract:

THz technology has developed to the point at which we can now begin to use customized-off-the-shelf components to construct near-real time imagers. One of the most widespread applications for this new instrumentation is in the field of security, especially undergarment threat detection. This talk will discuss current techniques in active THz scanning, both to introduce the phenomenology of what we see reflected off the body, as well as the hidden phenomenology of what THz radiation may be stimulating in the body. As we move forward with the technology development, there is a unique opportunity to couple new image processing tools and techniques with the implementation and design of new hardware.

Biography:

Peter H. Siegel (BA Colgate 1976, PhD Columbia, 1983, IEEE member since 1975) held appointments as Faculty Associate in Electrical Engineering and Senior Scientist in Biology at Caltech and Senior Research Scientist at the NASA Jet Propulsion Laboratory. At JPL, he founded and led for 20 years, the Submillimeter Wave Advanced Technology (SWAT) team, a group of 20+ scientists and engineers developing THz technology for NASA’s near and long term space missions, including four satellite instruments, as well as for several DoD applications. At Caltech, Dr. Siegel has been involved in new biological and medical applications of THz, especially low power effects on neurons and most recently, millimetre-wave monitoring of blood chemistry. Among many other functions, he serves as founding Editor-in-Chief of the IEEE Transactions on Terahertz Science and Technology and the General Secretary of the International Society of Infrared, Millimeter, and Terahertz Waves, which he founded in 2009.
