Ithemometha ye-infrared yomntu sisixhobo esilinganisa ubushushu bomzimba ngokufumana amandla e-infrared akhutshwa ngumzimba womntu. Into yokufumanisa ebuthathaka ngaphakathi kwethemometha idlulisela ulwazi lwamandla oluqokelelweyo kwi-microprocessor ukuze iqhutywe, kwaye emva koko iyiguqule ibe ngumboniso wokufunda wobushushu. Ke ngoko, ithemometha ye-infrared yomzimba womntu inezi zibonelelo zilandelayo: <br>(1) Umlinganiselo ongaqhagamshelwanga: akukho mfuneko yokubamba umzimba womntu, jonga nje ubushushu obumalunga ne-5 cm phambi kwebunzi, kwaye umtshina we-infrared ufuna ukuqonda kuphela imitha ye-infrared ekhutshwa ngumzimba womntu. Ke ngoko, ayiyi kuphazamisana nomzimba womntu kwaye ayiyi kubangela ingozi kumzimba womntu. <br>(2) Uluhlu olubanzi lokulinganisa: Ekubeni i-thermometer ye-infrared yomzimba womntu isilinganisi sokushisa esingadibanisiyo, i-thermometer ayikho kwindawo yokushisa ephezulu okanye ephantsi, kodwa isebenza kwiqondo lokushisa eliqhelekileyo okanye iqondo lokushisa elivunyelwe yi-thermometer. Umlinganiselo wenziwa phantsi kweemeko, ngoko ke uluhlu lokulinganisa lubanzi. <br>(3) Ukulinganisa ubushushu obukhawulezayo: oko kukuthi, ixesha lokuphendula likhawuleza. Into ebuthathaka kwisixhobo se-infrared sinovakalelo kakhulu, okoko nje ifumana ukukhanya kwe-infrared ekujoliswe kuyo, inokulinganisa ubushushu ngexesha elifutshane. <br>(4) Ukuchaneka okuphezulu: Umlinganiselo wokushisa we-infrared womzimba womntu awuyi kutshabalalisa ukuhanjiswa kweqondo lokushisa kwento ngokwayo njengomlinganiselo oqhelekileyo wokushisa, ngoko ke ukuchaneka komlinganiselo kuphezulu. <br>5 <br>(6) Ubungakanani obuncinci, kulula ukuthwala <br>(7) Ukuphazamiseka okuncinci kwiqondo lokushisa langaphandle: Ekubeni i-detector ye-infrared esetyenziswe kolu yilo inomjikelezo wembuyekezo, inokubuyisela ukuguquguquka kweqondo lokushisa langaphandle.
