Patent attributes
A portable noncontact thermometer comprising a housing defining an aperture for ingress of incident thermal energy in a field of view. A graphical display is fixed with respect to the housing. The thermometer further comprises a thermopile array including a plurality of thermopile elements positioned inside the housing so as to be impinged by the incident thermal energy. The thermometer further includes processing circuitry in electrical communication with the thermopile array. The processing circuitry is operative to produce on the graphical display a thermal image of the field of view. The processing circuitry is further operative to determine a temperature of a target location within the field of view based on electrical signals derived from a subset of the thermopile elements. The subset of thermopile elements may be a single thermopile element located approximately at a center of the thermopile array.
