STI Series Uncooled Terahertz Cameras

1. Uncooled Terahertz Camera Imager

Electromagnetic waves are around us in many different forms: light waves, radio waves, micro waves. We have been using their properties for years. Terahertz waves (THz) are the electromagnetic waves with frequencies between 100GHz and 10THz. THz radiation lies between microwaves and infrared light regions of the spectrum.

THz radiation have unique properties, it can go through a wide variety of non-conducting materials. They are low in energy (~4.1 meV) and non-ionizing so they are not harmful. We can use THz imaging technology for non-invasive and non-destructive testing in various fields like food, industry, medicine, etc

THz waves are absorbed by some liquids like water, and this property can be used to measure the internal moisture of various objects.

The terahertz waveband ranges from 100GHz to 10THz. At these frequencies, the electromagnetic waves have unique and interesting properties:

These waves penetrate non-polar materials such as plastic, ceramic, wood and fabric;
These waves are highly absorbed by water and moisture;
The energy used is very low and these waves are non-ionizing;

With this terahertz imager, you can see through materials, making it ideal for developing your non-destructive testing solutions, for detecting and inspecting defects in wood, paper/cardboard, polymers and plastics, ceramics, composites, plants, food, as well as for evaluating humidity rates in these same materials.

What's more, these terahertz waves are non-ionizing and therefore pose no risk to the human body, making this technology an attractive alternative to non-damaged testing (NDT) X-ray solutions.

LABORATORY: THz BEAM CHARACTERIZATION

The terahertz camera is essential for any laboratory or R&D institutions that carry out research in the field of THz waves and explores THz potential in various applications medical imaging, oncology etc. The wide range of coverage (0.1THz to 5THz) combined with an unrivalled bolometric sensor sensitivity makes the terahertz camera a perfect tool for visualisation /qualification of your terahertz laser source.

NDT / QUALITY CONTROL

Additionally, our terahertz camera eases the non-destructive testing of advanced materials used in various industries and industrial quality control. THz non-hazardous imaging technology reveals previously invisible defects inside the subject matter.

Our non-contact THz penetrating imaging system can detect manufacturing defects or imperfections inside parts during production, in real-time by seeing through the materials. THz imaging technology is ideal for industries needing to inspect materials such as plastic, ceramic, composites, polymers, wood, cardboard and paper, textile and fibers and leather.
