Recent developments in THz technology which led to the compact and efficient THz sources and detectors are opening up new avenues for pharmaceutical applications.  THz Pulse Imaging (TPI), one of the new methods for coherent non-invasive imaging which employs both amplitude and phase of the THz signal, has demonstrated promising results in characterization of …

Field Effect Transistors for Terahertz Detectors

Daniel Hailu Blog Leave a Comment

Electromagnetic waves in the terahertz frequency range can easily penetrate packaging materials and render image details in high resolution, and can also detect the chemical fingerprints of pharmaceutical drugs, biological weapons, or illegal drugs or explosives. However, most existing terahertz systems involve bulky and expensive laser setups that sometimes require …

Terahertz Emission Microscopy

In a terahertz time-domain spectroscopy, the spatial resolution is limited by the wavelength of the THz radiation, which is about 300μm at 1THz. To overcome this limitation, researchers at Okayama University (Okayama, Japan) have developed a laser-THz emission microscope (LTME) for non-destructive imaging of semiconductor devices. In this technique, the …
