Kev Taw Qhia Txog Cov Spectra Feem Ntau
1. Lub teeb RGB: Hais yooj yim xwb, nws yog lub teeb ntuj uas txhua tus pom hauv peb lub neej txhua hnub. R/G/B sawv cev rau peb lub xim tseem ceeb ntawm lub teeb pom kev: liab/ntsuab/xiav. Lub teeb uas txhua tus tuaj yeem pom yog tsim los ntawm peb lub teeb no. Sib xyaw ua ke, cov duab thaij hauv hom teeb pom kev no tsis txawv ntawm cov uas thaij ncaj qha nrog lub xov tooj ntawm tes lossis lub koob yees duab.
2. Lub teeb sib luag thiab lub teeb hla polarized
Yuav kom nkag siab txog lub luag haujlwm ntawm lub teeb polarized hauv kev nrhiav daim tawv nqaij, peb yuav tsum xub nkag siab txog cov yam ntxwv ntawm lub teeb polarized: cov teeb pom kev zoo sib luag polarized tuaj yeem ua kom muaj zog specular reflection thiab ua kom tsis muaj zog diffuse reflection; lub teeb hla-polarized tuaj yeem ua kom pom tseeb diffuse reflection thiab tshem tawm specular reflection. Ntawm qhov chaw ntawm daim tawv nqaij, qhov cuam tshuam specular reflection yog qhov pom tseeb dua vim yog cov roj ntawm qhov chaw, yog li nyob rau hauv hom teeb sib luag polarized, nws yooj yim dua los saib cov teeb meem ntawm daim tawv nqaij yam tsis raug cuam tshuam los ntawm lub teeb diffuse reflection tob dua. Hauv hom teeb hla-polarized, lub teeb specular reflection cuam tshuam ntawm daim tawv nqaij tuaj yeem lim tag nrho, thiab lub teeb diffuse reflection hauv cov txheej tob dua ntawm daim tawv nqaij tuaj yeem pom.
3. Lub teeb UV
Lub teeb UV yog lub npe luv ntawm lub teeb Ultraviolet. Nws yog qhov tsis pom ntawm qhov wavelength tsawg dua li lub teeb pom kev. Qhov ntau ntawm qhov wavelength ntawm lub teeb ultraviolet uas lub tshuab ntes siv yog ntawm 280nm-400nm, uas sib raug rau UVA (315nm-280nm) thiab UVB (315nm-400nm) uas feem ntau hnov. Cov teeb ultraviolet uas muaj nyob rau hauv cov teeb uas tib neeg raug rau txhua hnub yog nyob rau hauv qhov ntau ntawm qhov wavelength no, thiab kev puas tsuaj ntawm daim tawv nqaij txhua hnub feem ntau yog los ntawm cov teeb ultraviolet ntawm qhov wavelength no. Qhov no kuj yog vim li cas ntau dua 90% (tej zaum 100% qhov tseeb) ntawm cov khoom ntes tawv nqaij hauv khw muaj hom teeb UV.
Cov teeb meem ntawm daim tawv nqaij uas tuaj yeem pom tau hauv qab cov teeb pom kev sib txawv
1. Daim ntawv qhia RGB lub teeb: Nws nthuav tawm cov teeb meem uas lub qhov muag tib neeg ib txwm pom tau. Feem ntau, nws tsis siv ua daim ntawv qhia kev tshuaj xyuas tob. Nws feem ntau yog siv rau kev tshuaj xyuas thiab kev siv cov teeb meem hauv lwm hom teeb. Lossis hauv hom no, ua ntej tsom mus rau kev nrhiav cov teeb meem uas pom los ntawm daim tawv nqaij, thiab tom qab ntawd nrhiav cov laj thawj ntawm cov teeb meem sib xws hauv cov duab hauv hom teeb ci thiab UV raws li daim ntawv teev teeb meem.
2. Lub teeb polarized sib luag: feem ntau yog siv los saib cov kab zoo, cov qhov hws thiab cov pob ntawm daim tawv nqaij.
3. Lub teeb hla-polarized: Saib qhov rhiab heev, o, liab thiab cov xim sab saud hauv qab daim tawv nqaij, suav nrog cov cim pob txuv, cov pob me me, kub hnyiab, thiab lwm yam.
4. Lub teeb UV: feem ntau saib pob txuv, cov pob tob tob, cov khoom seem fluorescent, cov tshuaj hormones, cov kab mob dermatitis tob tob, thiab saib qhov sib sau ua ke ntawm Propionibacterium kom meej meej nyob rau hauv UVB lub teeb qhov chaw (Wu lub teeb) hom.
Cov Lus Nug Feem Ntau
Q: Lub teeb ultraviolet yog lub teeb uas tib neeg lub qhov muag tsis pom. Vim li cas cov teeb meem ntawm daim tawv nqaij thiaj pom tau hauv qab lub teeb ultraviolet?tshuaj ntsuam tawv nqaij?
A: Ua ntej, vim tias qhov luminous wavelength ntawm cov khoom ntev dua li qhov absorption wavelength, tom qab daim tawv nqaij nqus cov luv luv wavelength ultraviolet lub teeb thiab tom qab ntawd cuam tshuam lub teeb tawm, ib feem ntawm lub teeb cuam tshuam los ntawm daim tawv nqaij nto muaj qhov ntev wavelength thiab tau dhau los ua lub teeb pom kev rau tib neeg lub qhov muag; qhov thib ob Ultraviolet rays kuj yog electromagnetic waves thiab muaj volatility, yog li thaum qhov wavelength ntawm lub teeb ntawm cov khoom sib xws nrog qhov wavelength ntawm ultraviolet rays irradiated rau ntawm nws qhov chaw, harmonic resonance yuav tshwm sim, ua rau muaj qhov tshiab wavelength lub teeb qhov chaw. Yog tias qhov teeb pom kev no pom rau tib neeg lub qhov muag, nws yuav ntes los ntawm lub detector. Ib qho teeb meem yooj yim-rau-nkag siab yog tias qee cov tshuaj hauv cov tshuaj pleev ib ce tsis tuaj yeem pom los ntawm tib neeg lub qhov muag, tab sis fluoresce thaum raug rau ultraviolet lub teeb.
