Imithombo yokukhanya yahlulahlulwe ibe kukukhanya okubonakalayo kunye nokukhanya okungabonakaliyo. Umthombo wokukhanya osetyenziswa yiuhlalutyi lwesikhumbaUmatshini luhlobo ezimbini, enye kukukhanya kwendalo (RGB) kwaye enye kukukhanya kwe-UVA. Xa ukukhanya kwe-RGB + parallel polarizer, unokuthatha umfanekiso wokukhanya ohambelanayo; xa ukukhanya kwe-RGB + ukuwela i-polarizer, unokuthatha umfanekiso wokukhanya onqamlezileyo. Ukukhanya kweWood luhlobo lokukhanya kwe-UV.
Umgaqo kunye nomsebenzisye-3 iindidi ze-spectrum
I-parallel polarized lightumthombo unokomeleza umboniso okhethekileyo kwaye wenze buthathaka ukubonakalisa ukusabalalisa; Impembelelo yokubonakalisa imbonakalo ibonakala ngakumbi kumphezulu wolusu ngenxa ye-oyile engaphezulu, ngoko ke kwimowudi yokukhanya ehambelanayo, kulula ukujonga iingxaki zomphezulu wolusu ngaphandle kokuphazamiseka kukukhanya okunzulu okubonakalayo. Isetyenziselwa ikakhulu ukujonga imigca emihle, iipores, amabala, njl.
I cukukhanya kwe-ross-polarizedinokugxininisa imbonakalo eyohlukeneyo kwaye isuse imbonakalo ethile. Kwimowudi yokukhanya kwe-cross-polarized, ukuphazamiseka kokukhanya okubonakalayo okubonakalayo kumphezulu wolusu kunokucocwa ngokupheleleyo, kunye nokukhanya okubonakalayo okubonakalayo kumanqanaba anzulu esikhumba kunokubonwa. Ke ngoko, imifanekiso yokukhanya enqamlezileyo ingasetyenziselwa ukujonga ubuntununtunu, ukuvuvukala, ububomvu kunye nebala elingaphezulu kwesikhumba, kubandakanya amabala, amabala, ukutshiswa lilanga, njl.
Isibane seUVesetyenziswa yiuhlalutyi lwesikhumbaUmatshini yi-UVA (i-wavelength 320 ~ 400nm) umthombo wokukhanya onamandla aphantsi kodwa amandla okungena anamandla. Umthombo wokukhanya we-UVA unokungena kwi-dermis layer, ngoko ingasetyenziselwa ukujonga amabala anzulu kunye ne-dermatitis enzulu; kwangaxeshanye, ngenxa yokuba ukukhanya kwe-UV kukwaliza le-electromagnetic wave kwaye kunokuguquguquka, i-harmonics iya kwenzeka xa i-wavelength yemitha ye-substance ihambelana nobude bemitha ye-ultraviolet elayidiweyo kumphezulu wayo. I-wave ivuselela, idala i-wavelength entsha yokukhanya ukuba, ukuba ibonakala kwiliso lomntu, ibanjwe ngumatshini wokuhlaziya ulusu. Ngokusekelwe kulo mgaqo, i-porphyrins, iintsalela ze-fluorescent, amahomoni kunye nezinye izinto ezilusu zingabonwa. Ukuhlanganiswa kwePropionibacterium kucace kakhulu phantsi kwemowudi yokukhanya yeWood.
Kutheni i-spectra ye-high-endii-analzyers zesikhumbazingaphantsi kweemodeli zexabiso eliphantsi?
Abahlalutyi besikhumba abaphezulu abaphezulu (ISEMECO, RESUR) baneentlobo ze-3 kuphela ze-spectrum: i-RGB, ukukhanya kwe-cross-polarized, kunye nokukhanya kwe-UV;
II-MEICET MC88kwayeMC10iimodeli zineentlobo ezi-5 zespectrum: RGB, parallel polarized light, cross polarized light, UV light (365nm), kunye neWood's light (365+402nm);
Imodeli yobuchwephesha ithatha ikhamera ye-SLR yenkcazo ephezulu, kwaye imifanekiso ethathiweyo icace ngokwaneleyo, ukuze ukwazi ukubona iingxaki kumphezulu wolusu: i-pores, imigca emihle, amabala, njl njl. Ngendlela efanayo, kuba umfanekiso wokukhanya kwe-UV ucace ngokwaneleyo, akusekho mfuneko yokongeza ukukhanya kweWood ukujonga iqela lePropionibacterium.
Ngenxa yokubaMC88kwayeMC10imodeli isebenzisa ikhamera eza ne-iPad, iipixels azinakuthelekiswa naleyo yekhamera ye-SLR yobuchwephesha, ngoko ke ukukhanya okubonakalayo kuyafuneka ukuze kuphuculwe ukubonakaliswa okukhethekileyo komphezulu wolusu ukujonga iipores, imigca emihle, amabala kunye nezinye iingxaki. Ukongeza ukukhanya kweWood kunokwenza iqela lePropionibacterium liboniswe ngokucacileyo.
