Intshayelelo kwi-common spectra
1. Ukukhanya kwe-RGB: Ngokulula, kukukhanya kwendalo okubonwa ngumntu wonke kubomi bethu bemihla ngemihla.I-R/G/B imele imibala emithathu ephambili yokukhanya okubonakalayo: obomvu/oluhlaza/oluhlaza okwesibhakabhaka.Ukukhanya okubonwa ngumntu wonke kuqulunqwe zezi zibane zithathu.Ukuxuba, iifoto ezithathwe kule ndlela yomthombo wokukhanya azifani nezo zithathwe ngokuthe ngqo ngefowuni okanye ikhamera.
2. Ukukhanya kwe-parallel-polarized kunye nokukhanya kwe-cross-polarized
Ukuqonda indima yokukhanya kwe-polarized ekubhaqweni kwesikhumba, okokuqala kufuneka siqonde iimpawu zokukhanya kwe-polarized: imithombo yokukhanya ehambelanayo ye-polarized inokomeleza ukubonakaliswa okucacileyo kunye nokunciphisa ukubonakaliswa kwe-diffuse;Ukukhanya okunqamlezileyo kunokugqamisa ukubonakaliswa kokusabalalisa kunye nokuphelisa ukubonakaliswa okukhethekileyo.Kumphezulu wolusu, isiphumo sokubonakaliswa kwespecular sibonakala ngakumbi ngenxa yeoyile yomphezulu, ngoko ke kwimowudi yokukhanya ehambelanayo, kulula ukujonga iingxaki zomphezulu wolusu ngaphandle kokuphazamiseka kukukhanya okunzulu okubonakalayo.Kwimowudi yokukhanya kwe-cross-polarized, ukuphazamiseka kokukhanya okubonakalayo okubonakalayo kumphezulu wolusu kunokucocwa ngokupheleleyo, kunye nokukhanya okubonakalisiweyo okusasazekayo kwiingqimba ezinzulu zolusu kunokubonwa.
3. Ukukhanya kwe-UV
Ukukhanya kwe-UV sisifinyezo sokukhanya kwe-Ultraviolet.Yinxalenye engabonakaliyo yobude obungaphantsi kokukhanya okubonakalayo.Uluhlu lwe-wavelength yomthombo wokukhanya kwe-ultraviolet osetyenziswa ngumtshini uphakathi kwe-280nm-400nm, ehambelana ne-UVA eqhelekileyo (315nm-280nm) kunye ne-UVB (315nm-400nm).Imitha ye-ultraviolet equlethwe kwimithombo yokukhanya abantu abajongene nayo imihla ngemihla yonke ikulo luhlu lwe-wavelength, kwaye umonakalo we-photoaging wesikhumba wemihla ngemihla ubangelwa ikakhulu yimitha ye-ultraviolet yolu bude bamaza.Kungenxa yoko le nto ngaphezulu kwe-90% (mhlawumbi i-100% enyanisweni) yezixhobo zokubona ulusu kwimarike zinemowudi yokukhanya kwe-UV.
Iingxaki zolusu ezinokubonwa phantsi kwemithombo eyahlukeneyo yokukhanya
1. Imephu yomthombo wokukhanya we-RGB: Ibonisa iingxaki ezinokubonwa liso lomntu oqhelekileyo.Ngokuqhelekileyo, ayisetyenziswanga njengemephu yohlalutyo olunzulu.Isetyenziselwa ikakhulu ukuhlalutya kunye nokubhekisela kwiingxaki kwezinye iindlela zomthombo wokukhanya.Okanye kule modi, gxila kuqala ekufumaneni iingxaki ezibonakaliswa lusu, kwaye emva koko ujonge izizathu ezisisiseko zeengxaki ezihambelanayo kwiifoto ekukhanyeni kwe-cross-polarized kunye nemodi yokukhanya kwe-UV ngokoluhlu lweengxaki.
2. I-parallel polarized light: isetyenziselwa ukujonga imigca emihle, iipores kunye namabala kumphezulu wesikhumba.
3. Ukukhanya kwe-Cross-polarized: Jonga uvakalelo, ukuvuvukala, ubomvu kunye ne-pigments engaphezulu kwesikhumba, kubandakanywa iimpawu ze-acne, amabala, ukutshiswa kwelanga, njl.
4. Ukukhanya kwe-UV: ikakhulu jonga amaqhakuva, amabala anzulu, iintsalela ze-fluorescent, iihomoni, i-dermatitis enzulu, kwaye ujonge ukudityaniswa kwePropionibacterium ngokucacileyo phantsi komthombo wokukhanya we-UVB (ukukhanya kweWu).
FAQ
Umbuzo: Ukukhanya kwe-ultraviolet kukukhanya okungabonakaliyo kwiliso lomntu.Kutheni iingxaki zesikhumba zibonakala phantsi kokukhanya kwe-ultravioletuhlalutyi lwesikhumba?
A: Okokuqala, ngenxa yokuba ubude obukhanyayo bezinto bude kunobude bokufunxa, emva kokuba ulusu lufunxa amaza amaza amafutshane okukhanya kwe-ultraviolet emva koko abonakalise ukukhanya, inxalenye yokukhanya okubonakaliswa ngumphezulu wolusu inobude obude kwaye iye yaba sisibane esifutshane sobude obufutshane. ukukhanya okubonakalayo kwiliso lomntu;Imitha ye-Ultraviolet yesibini ikwangamaza e-electromagnetic kwaye ine-volatility, ngoko ke xa ubude bemitha yemitha yento buhambelana nobude bemitha ye-ultraviolet ekhanyiswa kumphezulu wayo, i-harmonic resonance iya kwenzeka, okukhokelela kumthombo omtsha wokukhanya wamaza.Ukuba lo mthombo wokukhanya ubonakala kwiliso lomntu, uya kubanjwa ngumtshini.Imeko ekulula ukuyiqonda kukuba ezinye izinto kwizithambiso azinakubonwa ngeliso lomntu, kodwa i-fluoresce xa ibonakaliswe kukukhanya kwe-ultraviolet.
