Cov kev cai thiab cov qauv rau kev txwv ntawm cov khoom hnyav hlau hnyav rau tib neeg lub cev nyob rau hauv ntau yam txheej tshwj xeeb rau electroplating ntawm hluav taws xob cua sov raj
Nrog rau kev txhim kho thev naus laus zis, txoj kev tshawb nrhiav thiab kev tshawb nrhiav hauv kev sib ntaus sib tua niaj hnub tau dhau los ua ntau haiv neeg. Ntawm lawv, hom kev tshawb nrhiav thiab kev tshawb nrhiav cov cuab yeej hauv qhov kho qhov muag (xws li pom lub teeb thiab ze-infrared) yog qhov dav tshaj plaws, nrog rau qhov kev daws teeb meem hauv av siab tshaj plaws thiab cov txiaj ntsig zoo tshaj plaws. Ntau hom optoelectronic reconnaissance cov cuab yeej raug faib thoob plaws hauv av, hiav txwv, thiab huab cua peb sab. Nyob rau hauv xyoo tas los no, txoj kev loj hlob ntawm hyperspectral imaging reconnaissance tau sai heev, thiab lub teb chaws nyob rau hauv lub tebchaws United States thiab cov teb chaws Europe tau successively launched ntau yam hyperspectral sensors xws li Hyperion, MODIS, MERIS, thiab ARTEMIS, ua ib qho tseem ceeb txhais tau tias ntawm anti camouflage thiab anti stealth [{ {2}}]. Nyob rau hauv qhov raug spectral nrhiav tau ntau yam (400-2500nm), lub "ntsuab reflection ncov" ntawm 550nm, "liab ntug" tsim los ntawm ib tug ntse nce nyob rau hauv reflectance ntawm 680-780nm, lub "ze infrared toj siab" nrog ib qho kev cuam tshuam ntawm 40-60 feem pua ntawm 780-1300nm, thiab plaub "dej nqus dej" ntawm 970nm, 1190nm, 1440nm, thiab 1920nm yog cov yam ntxwv ntawm qhov kev xav ntawm kev xav ntawm ntsuab angiosperms. Vim muaj kev cuam tshuam ntawm cov dej vapor nyob rau hauv cov huab cua, Tam sim no, "dej nqus dej" tsis tuaj yeem lees paub los ntawm cov khoom siv hauv nruab nrab thiab huab cua hyperspectral nrhiav pom, yog li "ntsuab reflection ncov", "liab ntug", thiab "ze infrared toj siab" tau dhau los ua cov yam ntxwv zoo rau cov chaw taws teeb pom kev paub txog ntsuab camouflage txheej hauv cov nroj tsuag ib puag ncig [3]. Cov txheej txheem camouflage yog hom phiaj kev soj ntsuam xws li kev pom, kev yees duab, thiab kev yees duab hauv lub teeb pom kev ntawm 380-780nm, nrog rau kev kuaj pom nrog 750-1200nm ze-infrared photography thiab cov cuab yeej pom kev hmo ntuj. Lawv muaj "ntsuab reflection peaks" thiab "liab npoo" zoo ib yam li cov nroj tsuag ntsuab, tab sis nyuaj rau simulate "ze-infrared toj siab" yam ntxwv ntawm cov nroj tsuag cov ntaub so ntswg. Ntawm qhov tod tes, cov xim daj inorganic nyob rau hauv cov tsoos camouflage txheej yog feem ntau chrome daj pigments, thiab hexavalent chromium nyob rau hauv cov txheej yuav ua rau mob loj rau tib neeg lub cev. Tam sim no, lub teb chaws tau tsim cov kev cai thiab cov qauv rau kev txwv qhov tseem ceeb ntawm cov khoom hnyav hnyav rau tib neeg kev noj qab haus huv hauv ntau cov txheej txheem tshwj xeeb, tshwj xeeb yog teeb tsa kev txwv rau cov hlau hnyav xws li txhuas, chromium, mercury, thiab cadmium [4]. Nws yog ib qho tseem ceeb kom txo qis cov xim hlau hnyav hnyav hauv cov txheej txheem thiab xyuas kom lawv muaj kev nyab xeeb siv.
