Description

Terahertz imaging cameras

- New physical principle employed


- Operates at frequencies (0.05 – 0.7 THz), where most common materials are transparent


256, 1024, 4096 pixels models are available - to accomodate any budget


-    USB feeding and programming


-    1.5 year warranty


The detectors are fabricated from GaAs high-mobility heterostructure in the standard semiconductor cycle using conventional optical lithography. The imaging sensor is manufactured on a single wafer. 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)1/2 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.
