  • OPTICAL MEASUREMENT OF A TEMPERATURE OF AN OBJECT, AND ASSOCIATED MAPPING
    Publication number: 20160216157
    Abstract: A method for the optical measurement of a variation in temperature of an object (O) includes: an emission step (S1) consisting of emitting, in the direction of the object (O), a first incident electromagnetic wave (W1_inc) of the terahertz type, and a measurement step (S2) including the measurement (S2_3), by a sensor sensitive to terahertz radiation (20), of a variation in amplitude of the electromagnetic radiation of a second electromagnetic wave (W2_ref, W2_tra) in order to determine the variation in temperature of the object (O).

  • 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.
