Inkqubo yokufumanisa ubushushu be-thermometer ye-infrared ingenziwa ngolu hlobo. <br>Inkqubo yokukhanya igxininisa ekujoliswe kuko kumandla emitha ye-infrared ngaphakathi kwendawo yokujonga. Ubungakanani bentsimi yokujonga inqunywe yi-optics ye-thermometer kunye nendawo yayo. Ikakhulu yenziwe sisihluzo kunye neFresnel lens, esetyenziselwa ukucoca imitha ye-infrared ngaphandle kwe-5^14um ukufezekisa injongo yokugxila. Amandla e-infrared agxininiswe kwi-photodetector kwaye aguqulelwe kwisignali yombane ehambelanayo. Umqondiso uguqulwa ube yixabiso lokushisa kwithagethi elinganisiweyo emva kokulungiswa yi-amplifier kunye ne-signal processing circuit ngokubhekiselele kwi-algorithm yonyango yangaphakathi yesixhobo kunye nokukhutshwa okujoliswe kuyo. Cofa iswitshi ukuthatha imilinganiselo, umlinganiselo ngamnye uboniswa kwidispleyi. <br>Xa inkqubo ilayitiwe, yonke isekethe iqalisa ukusebenza. Amandla aphuma kumphezulu wento kuqala agxininiswe yinkqubo yamehlo, emva koko afunyenwe yinzwa ye-pyroelectric, eguqula umqondiso wemitha ye-thermal ibe ngumqondiso wombane, okhuliswa yisekethe yeamplifier (i-clutter ebangelwa yimeko yangaphandle. ). Emva kokuba isiginali ihluzwe sisihluzo, ifikelela kwi-A/D ye-analog-to-digital converter. I-89S52 i-single-chip microcomputer isetyenziswa njenge-CPU Emva kokuguqulwa kwe-A/D, isignali yedijithali ifunyenwe. Emva kokucubungula idatha, iguqulelwa kubushushu bomphezulu bento kwaye iboniswe kwisiboniso se-LED.
