Isingeniso ku- common spectra
1. Ukukhanya kwe-RGB: Kalula nje, ukukhanya kwemvelo okubonwa yiwo wonke umuntu ekuphileni kwethu kwansuku zonke. I-R/G/B imele imibala emithathu eyinhloko yokukhanya okubonakalayo: obomvu/oluhlaza/oluhlaza okwesibhakabhaka. Ukukhanya okungabonwa yiwo wonke umuntu kwakhiwe lezi zibani ezintathu. Kuhlanganiswe, izithombe ezithathwe kule modi yomthombo wokukhanya azihlukile kulezo ezithathwe ngokuqondile ngomakhalekhukhwini noma ikhamera.
2. Ukukhanya kwe-Parallel-polarized kanye nokukhanya kwe-cross-polarized
Ukuze siqonde indima yokukhanya kwe-polarized ekuboneni isikhumba, okokuqala sidinga ukuqonda izici zokukhanya kwe-polarized: imithombo yokukhanya e-polarized parallel ingaqinisa ukubonakaliswa okukhethekile futhi yenze buthaka ukubonakaliswa kokusabalalisa; ukukhanya kwe-cross-polarized kungagqamisa ukubonisa okusabalalisayo futhi kuqede ukubonakaliswa okukhethekile. Ebusweni besikhumba, umphumela wokubonisa okukhethekile ubonakala kakhulu ngenxa yamafutha angaphezulu, ngakho-ke kumodi yokukhanya ehambisanayo ye-polarized, kulula ukubuka izinkinga zesikhumba ngaphandle kokuphazanyiswa ukukhanya okukhanyayo okujulile. Kumodi yokukhanya kwe-cross-polarized, ukuphazamiseka kokukhanya kwe-specular reflection endaweni yesikhumba kungahlungwa ngokuphelele, futhi ukukhanya okukhanyayo okusabalalisa ezingxenyeni ezijulile zesikhumba kungabonwa.
3. Ukukhanya kwe-UV
Ukukhanya kwe-UV isifinyezo sokukhanya kwe-Ultraviolet. Yingxenye engabonakali yobude beza obuncane kunokukhanya okubonakalayo. Ububanzi be-wavelength bomthombo wokukhanya kwe-ultraviolet osetshenziswa umtshina buphakathi kuka-280nm-400nm, obuhambisana ne-UVA evamise ukuzwakala (315nm-280nm) kanye ne-UVB (315nm-400nm). Imisebe ye-ultraviolet equkethwe emithonjeni yokukhanya abantu abachayeka kuyo nsuku zonke yonke ikulolu hlu lwamaza, futhi umonakalo wansuku zonke wokuthwebula izithombe zesikhumba ubangelwa ikakhulukazi imisebe ye-ultraviolet yalobu bude beza. Kungakho futhi ngaphezu kuka-90% (mhlawumbe u-100% eqinisweni) wezitholi zesikhumba emakethe zinemodi yokukhanya kwe-UV.
Izinkinga zesikhumba ezingabonwa ngaphansi kwemithombo yokukhanya ehlukene
1. Imephu yomthombo wokukhanya we-RGB: Iveza izinkinga ezingabonwa iso lomuntu ovamile. Ngokuvamile, ayisetshenziswa njengebalazwe lokuhlaziya ukujula. Isetshenziswa kakhulu ekuhlaziyeni nasekubhekiseni izinkinga kwezinye izindlela zomthombo wokukhanya. Noma kule modi, qala ugxile ekutholeni izinkinga ezivezwa yisikhumba, bese ubheka izimbangela zezinkinga ezihambisanayo ezithombeni ekukhanyeni kwe-cross-polarized kanye nemodi yokukhanya kwe-UV ngokusho kohlu lwezinkinga.
2. Ukukhanya kwe-polarized parallel: okusetshenziselwa ikakhulukazi ukubuka imigqa emihle, izimbotshana namachashaza ebusweni besikhumba.
3. Ukukhanya kwe-cross-polarized: Bheka ukuzwela, ukuvuvukala, ububomvu kanye ne-pigment engaphandle kwesikhumba, okuhlanganisa amabala, amabala, ukushiswa yilanga, njll.
4. Ukukhanya kwe-UV: ikakhulukazi bheka izinduna, amabala ajulile, izinsalela ze-fluorescent, amahomoni, i-deep dermatitis, futhi ubheke ukuhlanganiswa kwe-Propionibacterium ngokucacile ngaphansi kwemodi yomthombo wokukhanya we-UVB (ukukhanya kwe-Wu).
FAQ
Q: Ukukhanya kwe-ultraviolet ukukhanya okungabonakali emehlweni omuntu. Kungani izinkinga zesikhumba ngaphansi kokukhanya kwe-ultraviolet zingabonakala ngaphansiisikhumba analyzer?
IMPENDULO: Okokuqala, ngenxa yokuthi ubude begagasi obukhanyayo bento bude kunobude beza bokumuncwa, ngemva kokuba isikhumba simunca ukukhanya okufushane kwamaza amaza e-ultraviolet bese siveza ukukhanya, ingxenye yokukhanya ebonakala ebusweni besikhumba inobude obude futhi isibe yi-wavelength emfishane. ukukhanya okubonakalayo emehlweni omuntu; okwesibili imisebe ye-Ultraviolet nayo ingamagagasi kagesi futhi inokushintshashintsha, ngakho-ke lapho ubude begagasi bemisebe yento buhambisana nobude begagasi bemisebe ye-ultraviolet ekhanyiswe ebusweni bayo, kuzokwenzeka i-harmonic resonance, okuholela emthonjeni wokukhanya wamaza amaza amasha. Uma lo mthombo wokukhanya ubonakala ngeso lomuntu, uzobanjwa umtshina. Icala okulula ukuliqonda ukuthi ezinye izinto ezikwizimonyo azikwazi ukubonwa ngeso lomuntu, kodwa i-fluoresce lapho ivezwe ekukhanyeni kwe-ultraviolet.
