Kev lig kev cai, chromatic aberrations nyob rau hauv cheeb tsam pom spectral yog xam raws li kev ntsuas ntawm peb wavelengths: λF=486.1 nm (xiav Fraunhofer F kab los ntawm hydrogen) λD=589.2 nm (txiv kab ntxwv Fraunhofer D kab los ntawm sodium) λC=656.3 nm (liab Fraunhofer C kab los ntawm hydrogen)
Koj suav qhov aberration li cas?
Raws li qhov sib npaug no nws tuav tau tias(9) W=W ∞ + n ′ aa − (sa) 2 R (1 + cos θ) , sin 2 θ=aa − (sa) 2 R 2, qhov twg W yog lub nthwv dej aberration nrog kev hwm rau lub vojvoog siv ntawm lub vojvoog R, W∞yog lub nthwv dej aberration nrog rau kev siv sphere ntawm infinite radius, a=(0, δy , 0), s=(0, −sinφ, cosφ) …
Dab tsi yog cov tshuaj rau chromatic aberration?
Hloov koj cov duab xim rau xim dub thiab dawb. Siv lo ntsiab muag ua los ntawm cov iav uas tsis muaj kev sib cais, tshwj xeeb tshaj yog cov uas muaj fluorite. Lawv tuaj yeem txo cov chromatic aberration. Txhawm rau txo LoCA, tsuas yog tso tseg koj lub lens.
Dab tsi yog chromatic aberration hauv physics?
Chromatic aberration yog ib qho tshwm sim uas lub teeb ci dhau los ntawm lub lens tsom ntawm cov ntsiab lus sib txawv, nyob ntawm lawv qhov wavelength. Muaj ob hom chromatic aberration: axial chromatic aberration thiab lateral chromatic aberration.
Puas chromatic aberration normal?
Chromatic aberration (tseem hu ua xim fringing lossis dispersion)yog ib qho teeb meemfeem ntauhauv lo ntsiab muag uas tshwm sim thaum cov xim tsis raug refracted (khoov) los ntawm lub lens; qhov no ua rau muaj kev tsis sib haum xeeb ntawm qhov chaw focal uas cov xim tsis sib xyaw ua ke raws li lawv yuav tsum tau ua. Tsis meej pem? Txhob ua.
