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.

What is terahertz technology?

TPI is a completely non-invasive and non-destructive pharmaceutical analysis tool using extremely low power, ultra short pulses of electromagnetic radiation at lower frequencies than infrared (1 THz = 1012 Hz).

What frequency is terahertz radiation?

roughly 0.1 THz to 10 THz
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.

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.

What is terahertz made of?

The terahertz stone, an ore produced by extracting silica from sand or quartz was discovered by Japanese scientists a decade ago to have a terahertz vibration frequency which lies between that of microwaves and far infrared light on the electromagnetic spectrum with its frequency ranging from 0.1 to 30THz.
