Nyob rau hauv optics, chromatic aberration, kuj hu ua chromatic distortion thiab spherochromatism, yog ib tug tsis ua hauj lwm ntawm lub lens los tsom tag nrho cov xim rau tib lub ntsiab lus. Nws yog tshwm sim los ntawm dispersion: lub refractive index ntawm lub lens ntsiab nws txawv nrog lub wavelength ntawm lub teeb.
txhais li cas los ntawm monochromatic aberration?
Dab tsi yog monochromatic aberrations? Monochromatic aberrations yog aberrations uas tshwm sim hauv lub teeb quasimonochromatic. � Cov aberrations no tsis xav txog qhov cuam tshuam qhov zaus ntawm lub teeb muaj nyob rau hauv nws propagation los ntawm ib tug system. (Lub teeb tiag tiag yeej tsis monochromatic - nws ib txwm yog ua los ntawm ib pawg ntawm cov zaus.
Chromatic aberration yog dab tsi?
Chromatic aberration, xim distortion hauv ib daim duab saib los ntawm iav lo ntsiab muag. … Qhov kev hloov ntawm cov duab nyob deb nrog wavelength yog hu ua chromatic aberration, thiab qhov txawv ntawm magnification nrog wavelength yog hu ua chromatic sib txawv ntawm magnification, los yog lateral xim.
Dab tsi yog astigmatism aberration?
Astigmatism aberrations pom ntawm qhov chaw sab nraud ntawm qhov chaw saib hauv cov lo ntsiab muag tsis raug, thiab ua rau cov duab zoo tshaj plaws ncig (Airy pattern) plooj rau hauv lub voj voog, elliptical thaj, lossis kab, nyob ntawm qhov chaw ntawm lub dav hlau focal.
txhais tau li cas los ntawm kev sib txawv ntawm kheej kheej?
In thev naus laus zis ntawm kev yees duab: Aberrations. Spherical aberration yog tam sim no thaum lubsab nrauv ntawm ib lub lens tsis coj lub teeb rays mus rau tib lub hom phiaj raws li qhov nruab nrab. Cov duab tsim los ntawm lub lens ntawm apertures loj yog li ntawd tsis ntse tab sis tau ntse dua ntawm qhov apertures me.
Pom zoo:
Rau lateral chromatic aberration?
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.
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?
Puas yog kev pabcuam kev puas hlwb puas yog poj niam?
Txhua yam saum toj no tau coj qee tus kws tshawb fawb los qhia tias kev pabcuam kev puas hlwb yog inherently "feminized , " 2 , 86 raws li lawv ua ntej yam xws li kev hais lus, kev xav tsis zoo, thiab kev nthuav qhia tus kheej qhov tob uas yog qhov tseem ceeb ntawm kev kho mob (txhua tus neeg raug liam tias yog poj niam zoo).
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.
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.
