Taw qhia ntawm infrared rays rau tube txoj cai

Thaum cov hluav taws xob infrared tso tawm los tswj cov khoom siv tswj tau sib xws, kev tswj qhov deb yog proportional rau lub zog xa mus. Txhawm rau kom tswj tau qhov kev ncua deb ntawm infrared rays, lub infrared generator raj ua haujlwm nyob rau hauv lub xeev pulse, vim hais tias qhov kev sib kis tau zoo ntawm lub teeb mem tes (modulating teeb) yog proportional rau lub ncov tam sim no ntawm lub mem tes, qhov sib kis ntawm infrared ray tuaj yeem tau nce los ntawm kev txhim kho lub ncov Ip kom deb li deb tau.
