Estimating the term…
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.
A terahertz analysis device, comprising:
A converter for converting terahertz radiation into thermal radiation, comprising at least one zone sensitive to terahertz radiation, the sensitive zone being arranged to absorb the terahertz radiation and to convert the absorbed radiation into heat, said sensitive zone being in proximity to a reference zone of known absorption capacity for measuring the heat generated by the sensitive zone relative to the heat generated by the reference zone.
A method for terahertz analysis, wherein a converter is provided for converting terahertz radiation into thermal radiation, comprising at least one zone sensitive to terahertz radiation and arranged to absorb the terahertz radiation and convert the absorbed radiation into heat, said sensitive zone being in proximity to a reference zone of known absorption capacity, and the heat generated by the sensitive zone being measured relative to the heat generated by the reference zone.
