Abstract:
1. A portable noncontact thermometer comprising: a housing defining an aperture for ingress of incident thermal energy in a field of view; a graphical display fixed with respect to said housing; a thermopile array including a plurality of thermopile elements, said thermopile array being positioned inside said housing so as to be impinged by said incident thermal energy; processing circuitry in electrical communication with said thermopile array, said processing circuitry being operative to produce on said graphical display a thermal image of said field of view; said processing circuitry being further operative to determine a temperature of a target location within said field of view based on electrical signals derived from a subset of said thermopile elements; and wherein said subset of said thermopile elements are connected to said processing circuitry without passing through a multiplexer in a common package with said thermopile array whereas outputs of said thermopile elements which are not among said subset of thermopile elements are multiplexed before amplification.
