Lub teeb qhov chaw muab faib ua lub teeb pom kev thiab pom tsis pom. Lub teeb qhov chaw siv los ntawm lubdaim tawv nqaij analyzerLub tshuab yog ob hom, ib qho yog lub teeb ntuj (RGB) thiab lwm yam yog UVA lub teeb. Thaum RGB lub teeb + parallel polarizer, koj tuaj yeem nqa cov duab sib luag polarized; Thaum lub teeb RGB + cross polarizer, koj tuaj yeem nqa cov duab ntoo khaub lig polarized. Ntoo lub teeb kuj yog hom UV teeb.
Lub hauv paus ntsiab lus thiab kev ua haujlwmsntawm 3 hom spectrum
Parallel polarized teebqhov chaw tuaj yeem ntxiv dag zog rau qhov kev xav ntawm qhov xav tau thiab ua rau lub zog tsis muaj zog; qhov kev xav ntawm kev xav tau nthuav tawm ntau dua rau ntawm daim tawv nqaij vim yog cov roj saum npoo av, yog li nyob rau hauv kev sib piv polarized lub teeb hom, nws yooj yim dua los soj ntsuam cov teeb meem ntawm daim tawv nqaij yam tsis muaj kev cuam tshuam los ntawm qhov tob diffuse reflection lub teeb. Nws yog tsuas yog siv los saib xyuas cov kab zoo, qhov pores, me ntsis, thiab lwm yam ntawm daim tawv nqaij.
Cov cross-polarized lub teebtuaj yeem accentuate diffuse reflections thiab tshem tawm specular reflections. Nyob rau hauv hom cross-polarized lub teeb, lub specular reflection lub teeb cuam tshuam rau ntawm daim tawv nqaij saum npoo tuaj yeem lim tau tag nrho, thiab lub teeb pom kev sib txawv hauv cov khaubncaws sab nraud povtseg ntawm daim tawv nqaij tuaj yeem pom. Yog li ntawd, cov duab ntoo khaub lig-polarized tuaj yeem siv los soj ntsuam qhov rhiab heev, o, liab liab thiab cov xim ntawm daim tawv nqaij, nrog rau cov pob txuv, pob, sunburn, thiab lwm yam.
Lub teeb UVsiv los ntawmdaim tawv nqaij analyzertshuab yog UVA (wavelength 320 ~ 400nm) lub teeb qhov chaw uas tsis muaj zog tab sis muaj zog nkag mus rau lub zog. UVA lub teeb ci tuaj yeem nkag mus rau hauv cov txheej txheem dermis, yog li nws tuaj yeem siv los soj ntsuam cov pob sib sib zog nqus thiab sib sib zog nqus dermatitis; Nyob rau tib lub sijhawm, vim tias UV lub teeb kuj yog hluav taws xob nthwv dej thiab muaj volatility, harmonics yuav tshwm sim thaum lub wavelength ntawm cov hluav taws xob ntawm cov khoom muaj xws li lub wavelength ntawm ultraviolet rays irradiated ntawm nws nto. Lub nthwv dej resonates, tsim lub wavelength tshiab ntawm lub teeb uas, yog tias pom ntawm tib neeg lub qhov muag, raug ntes los ntawm daim tawv nqaij analyzer tshuab. Raws li txoj cai no, porphyrins, fluorescent residues, cov tshuaj hormones thiab lwm yam khoom ntawm daim tawv nqaij tuaj yeem pom. Kev sib sau ntawm Propionibacterium yog qhov tseeb heev nyob rau hauv Wood lub teeb hom.
Yog vim li cas lub spectrum ntawm high-enddaim tawv nqaij analzyerstsawg dua cov qauv pheej yig dua?
Cov kws tshuaj ntsuam xyuas tawv nqaij siab kawg (ISEMECO, RESUR) tsuas muaj 3 hom spectrum: RGB, hla lub teeb, thiab UV teeb;
CovTSI MC88thiabMC 10cov qauv muaj 5 hom spectrum: RGB, parallel polarized teeb, hla lub teeb, UV teeb (365nm), thiab Ntoo lub teeb (365 + 402nm);
Tus qauv kws tshaj lij tau txais lub koob yees duab macro kev tshaj lij SLR, thiab cov duab thaij tau pom tseeb txaus, yog li koj tuaj yeem pom cov teeb meem ntawm daim tawv nqaij: qhov pores, kab zoo, me ntsis, thiab lwm yam yam tsis tas siv cov polarizers sib npaug los txhim kho kev xav zoo. Nyob rau hauv tib txoj kev, vim hais tias ib tug UV teeb duab yog pom tseeb txaus, nws yog tsis tsim nyog ntxiv Wood lub teeb los soj ntsuam cov Propionibacterium pab pawg neeg.
Vim lubib MC88thiabMC 10qauv siv lub koob yees duab uas los nrog lub iPad, cov pixels tsis piv rau cov kws tshaj lij SLR lub koob yees duab, yog li lub teeb polarized yuav tsum tau txhim kho qhov kev xav ntawm daim tawv nqaij kom pom qhov pores, kab zoo, me ntsis thiab lwm yam teeb meem. Ntxiv Ntoo lub teeb tuaj yeem ua rau pawg Propionibacterium pom meej dua.
