What is terahertz imaging used for?
What is terahertz imaging used for?
Terahertz imaging is widely used in the study of semiconductor material properties, biomedical cell imaging, and chemical and biological examination. Terahertz time domain systems (THz-tds) have made significant advances in 2D imaging.
When was terahertz invented?
The first imaging system based on optoelectronic terahertz time-domain spectroscopy were developed in 1995 by researchers from AT Bell Laboratories and was used for producing a transmission image of a packaged electronic chip. This system used pulsed laser beams with duration in range of picoseconds.
Who discovered terahertz radiation?
In 2011, Albert Redo-Sanchez and his colleagues made an extraordinary discovery. Using terahertz technology, a recent addition to the array of imaging tools that can see beyond a painting’s surface, they uncovered a signature on a 1771 painting, Sacrifice to Vesta, by the great painter Francisco de Goya.
Is terahertz electromagnetic?
Terahertz radiation is typically understood to be electromagnetic radiation in the frequency range from roughly 0.1 THz to 10 THz, corresponding to wavelengths from 3 mm down to 30 μm. Such frequencies are higher than those of radio waves and microwaves, but lower than those of infrared light.
What is terahertz pulsed imaging?
Terahertz pulsed spectroscopy (TPS) and terahertz pulsed imaging (TPI) are two novel techniques for the physical characterization of pharmaceutical drug materials and final solid dosage forms, utilizing spectral information in the far infrared region of the electromagnetic spectrum.
What’s new in terahertz technology for pharmaceuticals?
Over the last ten years or so, terahertz technology has advanced considerably with both terahertz pulsed spectroscopy (TPS) and terahertz pulsed imaging (TPI) instruments now commercially available. This review outlines some of the recent pharmaceutical applications of terahertz pulsed spectroscopy and imaging.
What is the terahertz region?
The terahertz region of the electromagnetic spectrum spans the frequency range between the infrared and the microwave. Traditionally the exploitation of this spectral region has been difficult owing to the lack of suitable source and detector.
