Lateral Chromatic Aberration yog ua rau xim fringing. Nws tsuas yog pom ntawm ntug ntawm ib daim duab. Lateral chromatic aberration yog txo mus rau ib co degree los ntawm kev sib txuas cov ntsiab lus sib txawv nrog cov refractive indexes sib txawv, tab sis optically hais lus, nws tsis tuaj yeem tshem tawm tag nrho.
Dab tsi ua rau sab chromatic aberration?
Refraction muaj zog dua rau lub teeb ntawm luv wavelengths, piv txwv li xiav, thiab tsis tshua muaj zog rau lub teeb ntawm ntev wavelngths, piv txwv li liab. Ntau hom iav ua rau refraction lossis dispersion ntawm ntau yam siv. … Obliquely teeb pom kev ua rau LATERAL CHROMATIC ABERRATION.
Chromatic aberration formula yog dab tsi?
Qhov tsis muaj peev xwm ntawm lub lens los tsom txhua xim ntawm lub teeb ntawm ib qho taw tes yog hu ua chromatic aberration lossis axial lossis longitudinal chromatic aberration. Nws yog ntsuas los ntawm qhov sib txawv ntawm qhov ntev ntawm cov xim liab thiab violet. Chromatic aberration=fr–fv. Siv lub lens tsim cov qauv, rau lub ntsiab xim ntawm lub teeb, peb…
Koj txhais li cas los ntawm longitudinal chromatic aberration?
Longitudinal chromatic aberration (LCA) tshwm sim thaum sib txawv wavelengths tsom ntawm cov ntsiab lus sib txawv raws kab kab rov tav kho qhov muag raws li qhov tshwm sim ntawm cov khoom tawg ntawm iav.
Dab tsi yog hom chromatic aberration?
Muaj ob hom chromatic aberration: axial(longitudinal), thiab transverse (lateral). Axial aberration tshwm sim thaum txawv wavelengths ntawm lub teeb tsom ntawm qhov sib txawv ntawm lub lens (focus hloov).

Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pom kev pom?
Txawm li cas los xij, corneal collagen cross-linking - cov txheej txheem qib siab tau pom zoo los ntawm US Food and Drug Administration (FDA) hauv xyoo 2016 - tuaj yeem txhim kho qhov pom kev hauv cov neeg mob txhua hnub nyoog. Corneal collagen cross-linking (CXL) tsis yog kho rau keratoconus, tab sis nws tuaj yeem pab tiv thaiv tus mob kom tsis txhob mob hnyav.
Lub lens twg rau chromatic aberration?
Kev siv lub muaj zog zoo lo ntsiab muag ua los ntawm cov iav tawg qis zoo li cov iav iav txuas nrog lub iav tsis muaj zog siab zoo li iav iavtuaj yeem kho qhov chromatic aberration rau ob xim, Piv txwv li, liab thiab xiav. Ib lub lens puas tuaj yeem tshem tawm chromatic aberration?
Vim li cas chromatic aberration hauv kev ua si?
Kev Ntxiv Chromatic Aberration yuav ua rau qhov kev ua si zoo li yog nws tau thaij nrog lub koob yees duab. Niaj hnub no cov neeg tsim khoom lossis cov tshaj tawm xav tau qee yam kev ua yeeb yaj kiab hauv lawv cov kev ua si, ua rau cov nqi tsim khoom zoo li siab dua qhov tseeb (Kuv tab tom saib koj, letterboxing) thiab muaj peev xwm ntxiv qhov hnyav ntxiv rau qee qhov scenes.
Puas yog cov hlwb meristematic muaj nyob rau hauv lateral buds?
Meristematic cov ntaub so ntswg muaj nyob rau hauv ntau qhov chaw, suav nrog nyob ze ntawm lub tswv yim ntawm cov hauv paus hniav thiab stems (apical meristems), nyob rau hauv lub buds thiab nodes ntawm stems, nyob rau hauv lub cambium ntawm lub xylem thiab phloem nyob rau hauv dicotyledonous ntoo thiab shrubs, nyob rau hauv lub buds thiab nodes ntawm stems.
Formula rau chromatic aberration?
Kev lig kev cai, chromatic aberrations nyob rau hauv cheeb tsam pom spectral yog xam raws li kev ntsuas ntawm peb wavelengths: λ F =486.1 nm (xiav Fraunhofer F kab los ntawm hydrogen) λ D =589.2 nm (txiv kab ntxwv Fraunhofer D kab los ntawm sodium) λC =656.
