Terahertz Camera: The Industry’s “Holy Grail”

Daryoosh Saeedkia Blog Leave a Comment

A recent $5M investment by Phoenix Venture Partners on Traycer’s terahertz camera technology indicates the market potential for terahertz imaging technologies. Most of the existing terahertz imaging solutions on the market are based on single point detection scheme. While being useful tools for proof of concept purposes, the time it …

Terahertz Emission Microscopy

Alireza Zandieh Blog Leave a Comment

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 …

Terahertz Source Technologies

Terahertz (THz) frequency range with various interesting applications is not easily accessible. Over the past two decades, intense research has resulted in developing compact THz sources to be utilized in THz spectroscopy and imaging systems. THz sources can be divided into two major categories: electronic and photonic sources. THz electronic …

Photoconductive Antenna Material System

Alireza Zandieh Blog Leave a Comment

A photoconductive antenna (PCA) for terahertz (THz) waves consists of a highly resistive direct semiconductor thin film with two electric contact pads. The film is usually made of III-V compound semiconductors like GaAs. This material is epitaxially grown on a semi-insulating GaAs substrate (SI-GaAs), which is also a highly resistive …

Nondestructive Investigation of Historical Artworks

Paintings often consist of several layers subsequently applied in time. For revealing the images hidden beneath, discovering the chemistry of pigments, identifying the authors of unsigned works and probing the crack depths from damage or age, infrared radiation or X-ray are conventionally applied. The success of these techniques is usually …

After the Columbia disaster in 2003, NASA grounded the space shuttles for more than a year as it worked on new safety protocols to ensure that such a tragedy would not happen again. As part of the preparations for the Return to Flight mission, the Agency required a method for detecting …

The Healing Power of Terahertz Waves

Alireza Zandieh Blog Leave a Comment

Passing through different materials such as cloths, paper, and wood is not the only characteristic of the mystic terahertz radiation, could they also possess a healing power? Researchers in SHIMA Institution for Quantum Medicine (SIQM) have studied the effect of terahertz waves on the suppression of cancer cell growth. It …
