Mayelana ne-Spectrum of Skin Analyzer Machine

Imithombo yokukhanya ihlukaniswe ngokukhanya okubonakalayo nokukhanya okungabonakali. Umthombo wokukhanya osetshenziswa yi-isihlaziyi sesikhumbaUmshini empeleni unezinhlobo ezimbili, enye ukukhanya kwemvelo (RGB) kanti enye ukukhanya kwe-UVA. Uma usebenzisa i-RGB light + parallel polarizer, ungathatha isithombe sokukhanya okuhlanganisiwe okuhlanganisiwe; uma usebenzisa i-RGB light + cross polarizer, ungathatha isithombe sokukhanya okuhlanganisiwe okuhlanganisiwe. Ukukhanya kwezinkuni nakho kuwuhlobo lokukhanya kwe-UV.

Umgomo kanye nomsebenzisizinhlobo ezintathu ze-spectrum

Ukukhanya okuhlanganisiwe okuhlanganisiweUmthombo ungaqinisa ukubonakaliswa kwe-specular futhi unciphise ukubonakaliswa kwe-diffuse; umphumela wokubonakaliswa kwe-specular ubonakala kakhulu ebusweni besikhumba ngenxa yamafutha angaphezulu, ngakho-ke kwimodi yokukhanya ehlanganisiwe, kulula ukubona izinkinga zobuso besikhumba ngaphandle kokuphazamiseka ukukhanya okujulile kwe-diffuse reflection. Isetshenziswa kakhulu ukubona imigqa emincane, ama-pores, amabala, njll. ebusweni besikhumba.

I-cukukhanya okune-ross-polarizedingagcizelela ukubonakaliswa okusabalele futhi isuse ukubonakaliswa okusabalele. Kumodi yokukhanya okusabalele, ukuphazamiseka kokukhanya okusabalele ebusweni besikhumba kungahlungwa ngokuphelele, futhi ukukhanya okusabalele ezingqimbeni ezijulile zesikhumba kungabonakala. Ngakho-ke, izithombe zokukhanya okusabalele zingasetshenziswa ukubona ukuzwela, ukuvuvukala, ukubomvu kanye nombala ongaphezulu ngaphansi kobuso besikhumba, kufaka phakathi amamaki e-acne, amabala, ukushiswa yilanga, njll.

Isibani se-UVesetshenziswa yi-isihlaziyi sesikhumbaUmshini uwumthombo wokukhanya we-UVA (ubude be-wavelength 320 ~ 400nm) onamandla aphansi kodwa amandla anamandla okungena. Umthombo wokukhanya we-UVA ungangena ungqimba lwe-dermis, ngakho-ke ungasetshenziswa ukubona izindawo ezijulile kanye ne-dermatitis ejulile; ngesikhathi esifanayo, ngoba ukukhanya kwe-UV nakho kuyigagasi le-electromagnetic futhi kunokuguquguquka, ama-harmonics azokwenzeka lapho ubude be-wavelength ye-substance buhambisana nobude be-wavelength yemisebe ye-ultraviolet ekhanyiswe ebusweni bayo. Igagasi liyazwakala, lidala ubude be-wavelength obusha bokukhanya, uma bubonakala emehlweni omuntu, bubanjwa umshini wokuhlaziya isikhumba. Ngokusekelwe kulesi simiso, ama-porphyrins, izinsalela ze-fluorescent, ama-hormone nezinye izinto esikhumbeni zingabonakala. Ukuhlanganiswa kwe-Propionibacterium kucacile kakhulu ngaphansi kwemodi yokukhanya ye-Wood.

Kungani i-spectra ye-high-endizihlaziyi zesikhumbazingaphansi kwamamodeli ashibhile?

Abahlaziyi besikhumba abangochwepheshe abasezingeni eliphezulu (ISEMECO, RESUR) banezinhlobo ezintathu kuphela ze-spectrum: i-RGB, ukukhanya okuphambeneyo, kanye nokukhanya kwe-UV;

II-MEICET MC88futhiMC10Amamodeli anezinhlobo ezi-5 ze-spectrum: i-RGB, ukukhanya okuhlanganisiwe okuhlanganisiwe, ukukhanya okuhlanganisiwe okuhlanganisiwe, ukukhanya kwe-UV (365nm), kanye nokukhanya kukaWood (365+402nm);

Imodeli yobungcweti isebenzisa ikhamera ye-SLR yobungcweti esezingeni eliphezulu, futhi izithombe ezithathwe zicacile ngokwanele, ngakho ungabona izinkinga ebusweni besikhumba: ama-pores, imigqa emincane, amabala, njll. ngaphandle kokusebenzisa ama-polarizers ahambisanayo ukuthuthukisa ukubonakaliswa kwe-specular. Ngendlela efanayo, ngoba isithombe sokukhanya kwe-UV sicacile ngokwanele, akusadingeki ukwengeza ukukhanya kwe-Wood ukuze ubone iqembu le-Propionibacterium.

NgobaMC88futhiMC10Uma imodeli isebenzisa ikhamera eza ne-iPad, amaphikseli awafani nalawo ekhamera ye-SLR yobungcweti, ngakho-ke ukukhanya okune-polarized kuyadingeka ukuze kuthuthukiswe ukubonakaliswa kwe-specular kobuso besikhumba ukuze kubonwe ama-pores, imigqa emincane, amabala nezinye izinkinga. Ukwengeza ukukhanya kukaWood kungenza iqembu le-Propionibacterium libonakale ngokucacile.
