Ku-milaffairs, umthombo wokukhanya ojwayelekile wemishini yokukhanyisa egumbini lenjini ngeke nje unikeze ukukhanya, kodwa futhi ukhiphe ukukhanya ebhendini eseduze ye-infrared. Nakuba amandla okukhanya engekho phezulu, azobangela ukuphazamiseka okuthile ku-NVIS (uhlelo oluhambisana nombono wasebusuku). Njengamanje, indlela eqondile nesebenzayo yokuqeda lolu hlobo lokuphazamiseka ukusebenzisa isihlungi esiseduze ne-infrared. Lokhu akwenzi nje kuphela ukuthi isistimu ehambisanayo yokubona ebusuku isebenze ngokujwayelekile, kodwa futhi kwenza kube nzima ngohlelo lwesitha lokubona ebusuku ukusithola ebangeni elithile.
Njengamanje, izingilazi zokubona ebusuku ezinezinga eliphansi lokukhanya sezithuthukile zaze zafika esizukulwaneni sesine, futhi ibhande lomphumela lifana nelesizukulwane sesithathu (625 ~ 930 nm), kodwa ukuzwela kuyathuthukiswa. Ucwaningo lwalolu hlobo lwesihlungi esiseduze ne-infrared ikakhulukazi lusekelwe kusihlungi sepulasitiki esine-infrared esiseduze esikhiqizwa e-United States kanye nesihlungi sengilazi esiseduze ne-infrared esikhiqizwe eJalimane, kuyilapho izinga lokuthuthukiswa kwasekhaya lihlehle kakhulu, futhi asikho isihlungi esiseduze ne-infrared esingahlangabezana nezidingo zokuhambisana nombono wasebusuku.
Ukhiye wokukhiqiza izihlungi eziseduze ne-infrared ezihlangabezana namazinga ezempi ukusebenzisa odayi abahlonziwe abaseduze ne-infrared, ngoba akubona bonke odayi abaseduze kwe-infrared abangahlangabezana nezidingo. Ukuze kuhlangatshezwane nezidingo zokuhambisana kombono wasebusuku, i-absorber eseduze ye-infrared ingasetshenziswa yodwa, ihlanganiswe noma ixutshwe nodayi bepulasitiki abavamile, ukuze kwenziwe i-spectral amplitude nokukhanya kwe-NR value yayo ihambisane -1.0E+00≤ NR ≤ 1.7E-10, kanye nokukhanya kwayo kwe-chromatic yasebusuku ihlangabezana nezidingo zombala wokubona ebusuku, umbono wasebusuku A, umbala wombono wasebusuku. umbono obomvu nowasebusuku umhlophe), futhi ukudluliswa kokukhanya okubonakalayo akukho ngaphansi kwama-20%.
Ama-absorber aseduze ne-infrared ikakhulukazi ahlanganisa odayi be-cyanine, ama-phthalocyanines, ama-quinone, odayi be-azo kanye nezakhiwo zensimbi. Kungcono kakhulu ukuthi isibambisi se-infrared sibe nezinga eliphansi lokumunca endaweni yokukhanya ebonakalayo, ukumunca okuphezulu kahle endaweni eseduze ye-infrared kanye nokumuncwa okubanzi ngangokunokwenzeka. Ukulungiswa kwesihlungi se-optical kusebenzisa ubuchwepheshe be-dayi+polymer, obungambozwa phezulu noma bungezwe ngesikhathi se-polymerization.
