  • Terahertz imaging device with improved thermal converter
    Patent number: 8785852
    Abstract: The present invention relates to a terahertz imaging device comprising a terahertz source, a converter for converting terahertz radiation into thermal radiation, and a thermal detector. The converter has at least one zone sensitive to terahertz radiation, designed to absorb the terahertz radiation and vconvert the absorbed radiation into heat. This sensitive zone is close to a reference zone, of known absorption capacity, and the thermal detector is designed to measure the heat generated by the sensitive zone relative to the heat generated by the reference zone.
