Taw qhia rau cov spectrum
1. RGB teeb: Yooj yim muab, nws yog lub teeb ntuj uas txhua tus pom hauv peb lub neej niaj hnub.R / G / B sawv cev rau peb lub ntsiab xim ntawm lub teeb pom: liab / ntsuab / xiav.Lub teeb uas sawv daws pom tau yog tsim los ntawm peb lub teeb.Sib xyaw, cov duab thaij hauv hom teeb pom kev zoo no tsis txawv ntawm cov uas coj ncaj qha nrog lub xov tooj ntawm tes lossis lub koob yees duab.
2. Parallel-polarized lub teeb thiab cross-polarized teeb
Txhawm rau nkag siab txog lub luag haujlwm ntawm lub teeb pom kev zoo hauv kev tshawb pom ntawm daim tawv nqaij, peb yuav tsum xub nkag siab cov yam ntxwv ntawm lub teeb pom kev zoo: qhov chaw sib txuas ntawm lub teeb polarized tuaj yeem ntxiv dag zog rau qhov kev xav ntawm kev xav thiab tsis muaj zog diffuse reflection;cross-polarized lub teeb tuaj yeem nthuav dav diffuse reflection thiab tshem tawm specular reflection.Nyob rau saum npoo ntawm daim tawv nqaij, lub specular reflection nyhuv yog ntau pronounced vim cov roj saum npoo, yog li nyob rau hauv lub parallel polarized lub teeb hom, nws yog yooj yim dua los soj ntsuam cov tawv nqaij teeb meem ntawm daim tawv nqaij yam tsis muaj kev cuam tshuam los ntawm qhov tob diffuse reflection lub teeb.Nyob rau hauv hom cross-polarized lub teeb, lub specular reflection lub teeb cuam tshuam rau ntawm daim tawv nqaij saum npoo tuaj yeem lim tau tag nrho, thiab lub teeb pom kev sib txawv hauv cov khaubncaws sab nraud povtseg ntawm daim tawv nqaij tuaj yeem pom.
3. UV teeb
UV teeb yog lub ntsiab lus ntawm Ultraviolet lub teeb.Nws yog qhov pom tsis pom ntawm lub wavelength tsawg dua qhov pom lub teeb.Lub wavelength ntau yam ntawm lub teeb pom kev ultraviolet siv los ntawm lub teeb pom kev yog nyob nruab nrab ntawm 280nm-400nm, uas sib haum rau cov feem ntau hnov UVA (315nm-280nm) thiab UVB (315nm-400nm).Cov kab hluav taws xob ultraviolet uas muaj nyob rau hauv cov teeb pom kev zoo uas tib neeg raug rau txhua hnub yog tag nrho nyob rau hauv qhov kev sib tw wavelength, thiab txhua hnub ntawm daim tawv nqaij kev puas tsuaj feem ntau yog tshwm sim los ntawm ultraviolet rays ntawm no wavelength.Qhov no kuj yog vim li cas ntau tshaj 90% (tej zaum 100% qhov tseeb) ntawm cov tawv nqaij detectors ntawm lub khw muaj lub teeb UV hom.
Cov teeb meem ntawm daim tawv nqaij uas tuaj yeem pom nyob rau hauv qhov chaw sib txawv
1. RGB teeb pom kev zoo daim ntawv qhia: Nws nthuav tawm cov teeb meem uas tib neeg lub qhov muag pom tau.Feem ntau, nws tsis yog siv los ua daim ntawv qhia qhov tob.Nws yog tsuas yog siv rau kev tsom xam thiab siv cov teeb meem hauv lwm hom teeb pom kev zoo.Los yog nyob rau hauv hom no, ua ntej tsom mus rau kev tshawb nrhiav cov teeb meem tshwm sim los ntawm daim tawv nqaij, thiab tom qab ntawd nrhiav cov hauv paus ntsiab lus ntawm cov teeb meem sib xws hauv cov duab hauv lub teeb pom kev sib txawv thiab UV teeb hom raws li daim ntawv teev cov teeb meem.
2. Parallel polarized lub teeb: feem ntau yog siv los saib xyuas cov kab zoo, qhov pores thiab me ntsis ntawm daim tawv nqaij.
3. Hla-polarized lub teeb: Saib qhov rhiab heev, o, liab liab thiab xim ntawm daim tawv nqaij, nrog rau cov pob txuv, pob khaus, sunburn, thiab lwm yam.
4. UV lub teeb: feem ntau saib pob txuv, qhov tob tob, fluorescent residues, cov tshuaj hormones, sib sib zog nqus dermatitis, thiab soj ntsuam cov aggregation ntawm Propionibacterium kom meej meej nyob rau hauv UVB qhov chaw (Wu lub teeb) hom.
FAQ
Q: Ultraviolet lub teeb yog qhov pom tsis tau rau tib neeg lub qhov muag.Vim li cas thiaj muaj teeb meem ntawm daim tawv nqaij nyob rau hauv lub teeb ultraviolet pom hauv qabdaim tawv nqaij analyzer?
A: Ua ntej, vim hais tias lub luminous wavelength ntawm cov khoom yog ntev tshaj li qhov nqus wavelength, tom qab ntawm daim tawv nqaij absorbs lub luv luv wavelength ultraviolet lub teeb thiab ces xav txog lub teeb tawm, ib feem ntawm lub teeb reflected ntawm daim tawv nqaij nto muaj ib tug ntev wavelength thiab tau ua. pom lub teeb rau tib neeg lub qhov muag;Qhov thib ob ultraviolet rays kuj yog electromagnetic tsis thiab muaj volatility, yog li thaum lub wavelength ntawm cov hluav taws xob ntawm cov khoom yog raws li nyob rau hauv lub wavelength ntawm lub ultraviolet rays irradiated rau ntawm nws nto, harmonic resonance yuav tshwm sim, ua rau ib tug tshiab wavelength lub teeb qhov chaw.Yog tias qhov teeb pom kev no pom rau tib neeg lub qhov muag, nws yuav ntes tau los ntawm tus ntes.Ib qho yooj yim to taub yog tias qee yam khoom hauv tshuaj pleev ib ce tsis tuaj yeem pom los ntawm tib neeg lub qhov muag, tab sis fluoresce thaum raug ultraviolet teeb.
