Ob chav-pass infrared lim yog ib hom lim uas, nrog rau ib leeg-pass lim thiab IR-CUT thev naus laus zis, ua lub luag haujlwm tseem ceeb hauv kev kho qhov muag thiab kev ua duab. Lawv txhim kho cov txiaj ntsig ntawm daim ntawv thov thiab cov neeg siv kev paub ntawm cov cuab yeej siv lub koob yees duab niaj hnub nyob rau hauv cov teeb pom kev sib txawv los ntawm kev tsim kho qhov muag zoo thiab kev tswj xyuas ntse. Ob-pass infrared cov ntxaij lim dej muaj ntau yam ntawm cov ntawv thov scenarios, suav nrog tab sis tsis txwv rau kev saib xyuas kev ruaj ntseg, cov khoom siv hluav taws xob, kev tshawb fawb tshawb fawb thiab lwm yam kev lag luam, uas qhia dav dav hauv daim ntawv thov.
Cov yam ntxwv tshwj xeeb thiab kev siv ntawm ob-pass infrared lim yuav koom nrog kev tso cai rau lub teeb infrared ntawm cov wavelengths tshwj xeeb kom dhau los ntawm thaum thaiv lossis txo qis lub teeb ntawm lwm cov wavelength, yog li ua tiav qhov kev tshuaj ntsuam thiab txhim kho lub teeb infrared. Cov lim dej zoo li no yuav txawv ntawm cov khoom siv thiab cov khoom siv kho qhov muag. Piv txwv li, qee qhov yuav ua los ntawm cov iav xim, thaum lwm tus tuaj yeem ua los ntawm lub tshuab nqus tsev ntawm cov iav dawb. Kev xaiv ntawm cov kev tsim khoom sib txawv thiab cov txheej txheem kev ua haujlwm yog kom tau raws li cov kev xav tau tshwj xeeb ntawm infrared lub teeb ua hauv cov ntawv thov tshwj xeeb.
Feem ntau, ob-pass infrared lim yog ib feem tseem ceeb ntawm kev kho qhov muag thiab cov duab ua tshuab. Lawv ua tiav qhov kev tshuaj ntsuam thiab txhim kho lub teeb infrared los ntawm kev tsim tshwj xeeb thiab tsim cov txheej txheem, yog li txhim kho kev ua haujlwm ntawm cov khoom siv koob yees duab hauv ntau qhov chaw.
