We present what is to our knowledge the first imaging system based on optoelectronic terahertz time-domain spectroscopy. Terahertz time-domain waveforms are downconverted from the terahertz to the kilohertz frequency range, and the waveform for each pixel is frequency analyzed in real time with a digital signal processor to extract compositional information(More)
The Department of Homeland Security, Science and Technology Directorate (DHS/S&T) is exploring the feasibility to geolocate pollen grains found on goods or people for compliance with U.S. import laws and criminal forensics. A multidisciplinary team built the Pollen Identification and Geolocation Technology (PIGLT) system to help users identify pollen(More)
Reliability of power electronic systems is a major concern for application engineers in the automotive and power system sectors. Power electronic modules are one of the main sources of failure in wind energy conversion systems. Power electronic converters used in wind turbine electric drivetrains, railway traction, more-electric-aircrafts, marine propulsion(More)
