Would you like a camera that can see into a product without the use of harmful X-rays?
The solution is to use sub -THz imaging cameras manufactured by Terasense.
Ideal for a wide range of applications including:-
- Hidden Object and defect detection
- Security
- Medical Diagnostics
- Quality control
Standard cameras are available with 256, 1024 or 4096 pixels.
The imaging sensors for the cameras are manufactured on a single wafer and constructed using detectors which are fabricated from GaAs high-mobility heterostructure in the standard semiconductor cycle using conventional optical lithography. That process ensures high homogeneity and reproducibility of the plasmonic detector parameters (pixel-to-pixel deviation responsivity is within 20-percent range). Each unit detector proved to have room-temperature responsivity up to 50 kV/W with read-out circuitry and noise equivalent power 1 nW/Hz^0.5 in the frequency range 10 GHz – 1 THz. The detection mechanism is based on transformation of incident THz radiation into two-dimensional electron system (2DES) plasma oscillation. Plasma wave is then rectified on the inhomogeneity of 2DES electron density in the defect region.
Terasense have just launched production of our NEW wide sensor arrays (4 x 256 pixels) for our sub-THz imaging, which are meant to satisfy specific demand in THz-imaging for conveyor belt industrial applications and will surely be an ideal solution for high-speed conveyor belts.
