Terahertz imaging Systems
TeraSense has developed an original patent-protected technology for making a new generation of semiconductor detector arrays for terahertz imaging. The detectors operate at room temperature and arrays are scalable in the number of pixels.
TeraSense is producing imaging equipment for Terahertz (THz) and sub-THz frequency ranges. Revolutionary, patent-protected Terasense technology allows to manufacture a new type of semiconductor cameras, detectors and sources of terahertz radiation. TeraSense devices bridge terahertz gap (0.1 – 1 THz). The company has a strong team of 40 skilled scientists and engineers.

Terahertz imaging cameras
The detectors are fabricated with a 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 a 20- percent range). Each detector unit has a room-temperature responsivity up to 50 kV/W with read-out circuitry and noise-equivalent power of 1 nW/\sqrt{\rm{Hz}} in the frequency range 10 GHz — 1 THz. The detection mechanism is based on excitation of plasma oscillations in a two-dimensional electron system with subsequent rectification. The rectification takes place on special defects made in the electron system.
Our terahertz cameras are active detecting devices, and require an external THz source. We offer sub-terahertz wave sources based on IMPATT technology. All our TERA-series THz imaging cameras employ the same type of detectors with identical capabilities and spatial resolution. The difference between our models lies in the number of pixels in their sensor arrays and their effective imaging area.
In addition to our standard THz camera models we offer customized solutions to satisfy diverse configuration and geometry requirements.
