Terahertz imaging comes into view
Imaging technology is becoming increasingly prevalent in our society. X-ray scanners are routinely used to examine luggage at airports, for example, and most hospitals are equipped with ultrasound
Applications of terahertz (THz) technology to medical imaging
An imaging system has been developed based on pulses of Terahertz (THz) radiation generated and detected using all- optical effects accessed by irradiating semiconductors with ultrafast pulses of
Enhanced coherent terahertz emission from indium arsenide in the presence of a magnetic field
We demonstrate enhancement of terahertz (THz) emission from indium arsenide at 170 K in magnetic fields (B) up to 8 T. An order of magnitude increase in visible to terahertz conversion efficiency was
Terahertz Pulse Imaging: A Pilot Study of Potential Applications in Dentistry
Results for the detection of early stage caries in the occlusal enamel layer of a range of human tooth cross sections using terahertz pulse imaging have important implications for extending TPI to other medical imaging applications where both early diagnosis and safety issues are important.
Pump-probe transmission experiments have been performed on PbSe above the fundamental absorption edge near 4mm in the temperature range 30 to 300 K, using the Dutch ps free-electron laser. For
Suppression of Auger recombination in arsenic‐rich InAs1−xSbx strained layer superlattices
Room-temperature pump-probe transmission experiments have been performed on an arsenic-rich InAs/InAs1-xSbx strained layer superlattice (SLS) above the fundamental absorption edge near 10 mu m, using
Landau level lifetimes in an InAs/AlSb quantum well determined by a picosecond far-infrared pump-probe technique
We present measurements of Landau level lifetimes in a doped quantum well structure of InAs/AlSb using a combination of pump-probe and saturation spectroscopy measurements. The cyclotron resonance
Biomedical applications of terahertz pulse imaging
We present Terahertz Pulse Imaging (TPI) results of different human tissue types. Our results are part of an initial study to explore the potential of TPI for biomedical applications. A survey of
