The Need-to-Knows for Students The month of September and the new school year are nearly upon us (as is the realization that you can’t find a box of Kraft Dinner within 20km of a school campus!). For the post-secondary students out there, you are just now settling into your new …

Starting Up a Start-Up: Our Time at the AC

Kelly Hall Blog Leave a Comment

“Success starts at the AC.” Our Founder and CEO Daryoosh Saeedkia had that to say when asked what one thing he would say to describe TeTechS’ experience at the Waterloo Accelerator Centre (the AC). This past June, TeTechS graduated from the AC but we just recently were able to find …

Terahertz Technology for Microelectronic Package Fault Isolate and Failure analysis

Kelly Hall Blog Leave a Comment

Electro-optical terahertz pulse reflectometry (EOTPR), an electro-optical system driven by an ultrafast laser source, was introduced recently to isolate faults and detect defects in advanced IC packages. The steadily growing complexity of integrated-circuit (IC) technology is pushing the available inspection and fault-analysis tools to their limits. Among the nondestructive methods, …

Using Terahertz Imaging and Spectroscopy for Food Inspection

Kelly Hall Blog 1 Comment

Wait, you found WHAT in a chocolate bar?! Recent advances in Terahertz (THz) technology have enabled various applications in food inspection and quality control of powders. Although there are some notable limitations, there are also demonstrated benefits of the use of this technology for both food products and the packages …

Terahertz Imaging Applications in Cancer Detection

Kelly Hall Blog Leave a Comment

As a result of extensive research over the last decade, Terahertz (THz) technology has advanced considerably including around the application of THz imaging in biological problems. Compared to X-ray imaging, THz waves can realize a non-invasive and non-ionizing imaging for biological tissues due to the low photon energy. The scattering …

Terahertz Camera For Security Check

Daryoosh Saeedkia Blog Leave a Comment

In recent years, a number of terahertz full body scanners are deployed at the airports and other security checkpoints around the world. According to a recent news report, the New York Police Department (NYPD) has started testing a new remote terahertz gun detection system which can detect firearms concealed beneath layers …

Terahertz Imaging is Viable Alternative to X-ray for Dental Imaging

Daniel Hailu Blog Leave a Comment

The terahertz (THz) region of the electromagnetic (EM) spectrum has several advantages for skin cancer detection, dental imaging, and pharmaceutical applications. Continuous wave (CW) and pulsed THz transmission-mode and reflection-mode imaging with non-ionizing and noninvasive properties for tooth imaging are considered an alternative modality to X-ray imaging. Dental imaging application …
