Special <strong>Cameras</strong> Terahertz Imaging <strong>Cameras</strong> 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 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. Advantages • High homogeneity and reproducibility • High sensitivity • Fast image acquisition rate • Extremely compact design • USB feeding and programming • Terasense Viewer ® Software 48
