Intshayelelo kwi-common spectra
1. Ukukhanya kwe-RGB: Ngamafutshane, 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 kwenziwa zezi zibane zintathu. Xa zixutyiwe, iifoto ezithathwe kule ndlela yomthombo wokukhanya azihlukanga kwezo zithathwe ngqo ngefowuni okanye ikhamera.
2. Ukukhanya okujikelezileyo kunye nokukhanya okujikelezileyo
Ukuze siqonde indima yokukhanya okupholisiweyo ekufumaneni ulusu, kufuneka siqale siqonde iimpawu zokukhanya okupholisiweyo: imithombo yokukhanya okupholisiweyo okupholisiweyo okuhambahambayo inokomeleza ukubonakaliswa kwe-specular kwaye yenze buthathaka ukubonakaliswa kwe-diffuse; ukukhanya okupholisiweyo okuhambahambayo kunokuqaqambisa ukubonakaliswa kwe-diffuse kwaye kususe ukubonakaliswa kwe-specular. Kumphezulu wolusu, isiphumo sokubonakaliswa kwe-specular sibonakala ngakumbi ngenxa yeoyile yomphezulu, ngoko ke kwimo yokukhanya okupholisiweyo okuhambahambayo, kulula ukubona iingxaki zomphezulu wolusu ngaphandle kokuphazanyiswa kukukhanya okupholisiweyo okuhambahambayo okunzulu. Kwimo yokukhanya okupholisiweyo okuhambahambayo, ukuphazamiseka kokukhanya okupholisiweyo okuhambahambayo kumphezulu wolusu kunokuhluzwa ngokupheleleyo, kwaye ukukhanya okupholisiweyo okuhambahambayo kumaleko anzulu elusu kunokubonwa.
3. Isibane se-UV
Ukukhanya kwe-UV sisifinyezo sokukhanya kwe-Ultraviolet. Yinxalenye engabonakaliyo yobude be-wavelength obungaphantsi kokukhanya okubonakalayo. Uluhlu lwamaza okukhanya komthombo wokukhanya kwe-ultraviolet osetyenziswa yi-detector luphakathi kwe-280nm-400nm, oluhambelana ne-UVA eviwayo rhoqo (315nm-280nm) kunye ne-UVB (315nm-400nm). Imitha ye-ultraviolet equlethwe kwimithombo yokukhanya abantu abachatshazelwa kuyo yonke imihla ikuluhlu lwamaza okukhanya, kwaye umonakalo wemihla ngemihla wokubona ulusu ubangelwa kakhulu yimitha ye-ultraviolet yale wavelength. Kungoko ke ngaphezu kwe-90% (mhlawumbi i-100% eneneni) yezixhobo zokubona ulusu ezikwimarike zinemodi yokukhanya kwe-UV.
Iingxaki zesikhumba ezinokubonwa phantsi kwemithombo eyahlukeneyo yokukhanya
1. Imephu yomthombo wokukhanya we-RGB: Ibonisa iingxaki ezinokubonwa liliso lomntu eliqhelekileyo. Ngokubanzi, ayisetyenziswa njengemephu yohlalutyo lobunzulu. Isetyenziselwa ikakhulu uhlalutyo kunye nokubhekisa kwiingxaki kwezinye iindlela zomthombo wokukhanya. Okanye kule ndlela, gxila kuqala ekufumaneni iingxaki ezibonakaliswa lulusu, uze ujonge izizathu ezisisiseko zeengxaki ezifanayo kwiifoto kwimodi yokukhanya okunqamlezileyo kunye nokukhanya kwe-UV ngokwendlela yoluhlu lweengxaki.
2. Ukukhanya okujikelezileyo okufana ne-polarized: kusetyenziswa kakhulu ukujonga imigca emincinci, ii-pores kunye namabala kumphezulu wesikhumba.
3. Ukukhanya okunqamlezileyo: Jonga ubuzwe, ukudumba, ukubomvu kunye nemibala engaphezulu phantsi kolusu, kuquka amabala e-acne, amabala, ukutsha lilanga, njl.njl.
4. Ukukhanya kwe-UV: jonga ikakhulu i-acne, amabala anzulu, iintsalela ze-fluorescent, ii-hormone, i-deep dermatitis, kwaye ujonge ukuhlangana kwePropionibacterium ngokucacileyo phantsi kwendlela yokukhanya kwe-UVB (ukukhanya kukaWu).
FAQ
U: Ukukhanya kwe-ultraviolet kukukhanya okungabonakaliyo emehlweni omntu. Kutheni iingxaki zolusu phantsi kokukhanya kwe-ultraviolet zinokubonwa phantsiisihlalutyi solusu?
A: Okokuqala, kuba ubude bomda obukhanyayo bento bubude kunobude bomda wokufunxa, emva kokuba ulusu lufunxa ukukhanya kwe-ultraviolet obufutshane buze bubonakalise ukukhanya ngaphandle, inxalenye yokukhanya ebonakaliswa ngumphezulu wesikhumba inobude bomda obude kwaye ibe kukukhanya okubonakalayo kwiliso lomntu; okwesibini imisebe ye-Ultraviolet ikwangamaza e-electromagnetic kwaye ine-volatility, ngoko ke xa ubude bomda bento buhambelana nobude bomda bemitha ye-ultraviolet ekhanyiswa kumphezulu wayo, kuya kwenzeka i-harmonic resonance, nto leyo ekhokelela kumthombo omtsha wokukhanya we-wavelength. Ukuba lo mthombo wokukhanya ubonakala kwiliso lomntu, uya kubanjwa yi-detector. Ityala elilula ukuliqonda kukuba ezinye izinto kwi-cosmetics azinakubonwa liliso lomntu, kodwa ziyakhanya xa zibonakaliswa kukukhanya kwe-ultraviolet.
