Selelekela ho common spectra
1. Leseli la RGB: Ka mantsoe a bonolo feela, ke leseli la tlhaho leo motho e mong le e mong a le bonang bophelong ba rona ba letsatsi le letsatsi. R/G/B e emela mebala e meraro ea mantlha ea khanya e bonahalang: e khubelu/e tala/putsoa. Leseli leo motho e mong le e mong a ka le bonang le entsoe ka mabone ana a mararo. Ho kopantsoe, lifoto tse nkiloeng ka mokhoa ona oa mohloli oa leseli ha li fapane le tse nkiloeng ka ho toba ka selefouno kapa k'hamera.
2. Leseli la parallel-polarized le khanya ea polarized cross-polarized
Ho utloisisa karolo ea polarized leseli ho lemoha letlalo, re lokela ho qala ka ho utloisisa litšobotsi tsa polarized leseli: parallel polarized leseli mehloli e ka matlafatsa specular reflection le fokolisa diffuse reflection; khanya e nang le polarized cross-polarized lighting e ka totobatsa ponahalo e pharalletseng, 'me ea felisa ponahalo e ikhethang. Ka holim'a letlalo, phello e ikhethang ea ho bonahatsa e bonahala haholoanyane ka lebaka la oli e ka holimo, kahoo ka mokhoa o ts'oanang oa polarized light mode, ho bonolo ho bona mathata a holim'a letlalo ntle le ho khathatsoa ke leseli le tebileng la ho bonahatsa leseli. Ka mokhoa oa khanya oa polarized cross-polarized light, ho kena-kenana le leseli le ikhethang holim'a letlalo ho ka hloekisoa ka ho feletseng, 'me khanya e khanyang e khanyang likarolong tse tebileng tsa letlalo e ka bonoa.
3. Leseli la UV
Leseli la UV ke khutsufatso ea leseli la Ultraviolet. Ke karolo e sa bonahaleng ea bolelele ba maqhubu a tlase ho feta khanya e bonahalang. Leqhubu la maqhubu a mohloli oa leseli la ultraviolet le sebelisoang ke detector le pakeng tsa 280nm-400nm, e lumellanang le UVA e atisang ho utluoa (315nm-280nm) le UVB (315nm-400nm). Mahlaseli a ultraviolet a fuperoeng ke mehloli ea leseli ao batho ba pepesetsoang ho ona letsatsi le leng le le leng a sebakeng sena sa leqhubu la maqhubu, 'me tšenyo ea letsatsi le letsatsi ea photoaging ea letlalo e bakoa haholo-holo ke mahlaseli a ultraviolet a bolelele bona ba maqhubu. Ke ka lebaka lena ho feta 90% (mohlomong 100% ha e le hantle) ea lisebelisoa tsa letlalo 'marakeng li na le mokhoa oa khanya oa UV.
Mathata a letlalo a ka bonoang tlas'a mehloli e fapaneng ea leseli
1. 'Mapa oa mohloli oa leseli oa RGB: E fana ka mathata ao leihlo le tloaelehileng la motho le ka a bonang. Ka kakaretso, ha e sebelisoe e le 'mapa oa tlhahlobo ea botebo. E sebelisoa haholo-holo ho hlahloba le ho bua ka mathata ka mekhoa e meng ea mohloli oa leseli. Kapa ka mokhoa ona, qala ka ho tsepamisa maikutlo ho fumana mathata a hlahang letlalong, ebe u batla lisosa tse bakang mathata a tšoanang lifotong tsa lebone la polarized le mokhoa oa khanya oa UV ho latela lenane la mathata.
2. Parallel polarized light: haholo-holo e sebelisetsoang ho shebella mela e metle, li-pores le matheba holim'a letlalo.

P: Leseli la ultraviolet ke leseli le sa bonahaleng mahlong a motho. Ke hobane'ng ha mathata a letlalo tlas'a leseli la ultraviolet a ka bonoa tlas'aletlalo analyzer?
A: Taba ea pele, hobane bolelele bo khanyang ba ntho bo bolelele ho feta bolelele ba maqhubu a ho monya, ka mor'a hore letlalo le monye khanya e khuts'oane ea leqhubu la ultraviolet ebe le khantša leseli, karolo ea leseli le bonahatsoang ke bokaholimo ba letlalo e na le bolelele bo bolelele mme e fetohile. leseli le bonahalang mahlong a motho; Mahlaseli a bobeli a Ultraviolet e boetse ke maqhubu a motlakase 'me a na le ho hloka botsitso, kahoo ha bolelele ba maqhubu a mahlaseli a ntho a lumellana le bolelele ba maqhubu a mahlaseli a ultraviolet a khantšitsoeng holim'a eona, ho tla ba le molumo oa harmonic, o hlahisang mohloli o mocha oa leseli. Haeba mohloli ona oa leseli o bonahala mahlong a motho, o tla tšoaroa ke detector. Taba e batlang e utloisisoa habonolo ke ea hore lintho tse ling tse litlolong li ke ke tsa bonoa ke leihlo la motho, empa li-fluoresce ha li pepesehetse leseli la ultraviolet.
