Spectrum Detector been selected by Dr John Young at the University of Manchester to develop a unique eight-element pyroelectric detector array and accompanying electronics for use in a terahertz tomography project that is being pursued jointly with the University of Leeds and the University of Southampton, funded by the UK's Engineering and Physical Sciences Research Council (EPSRC).

The company has revealed that the first of several arrays has been completed and provided to Dr Young for test and evaluation. The goal was to create a multi-element linear array with large, 3mm diameter elements, that exhibiting high voltage output and low noise (NEP < 1.0 x 10-9W/(Hz)1/2). The detector will be used with a novel fibre laser-based terahertz source in the 0.5-2THz range. The research involves investigating terahertz absorption in the water bands of high-pressure flames.
