Abstract

The influence of smoke on THz imaging was examined. We tested experimentally a passive THz camera - TS4 from ThruVision Systems Ltd. The camera detects natural human radiation at a frequency of 0.25 THz. The distance camera-target could be 3-15 meters. Moreover, Time Domain Spectroscopy was used to investigate the  influence of the amount of smoke on transmission in the (0.1÷2.5) THz range.

...In order to check the influence of smoke on transmission in the THz range, we exploited Time  Domain Spectroscopy (TDS) [2, 4, 5] . The TDS gives us  opportunity to measure transmission in the (0.1 ÷2.5) THz  range. In the experiment setup we applied a spectrometer TPS Spectra 3000 from TeraView [7]...
