Muaj rau yam sib txawv lens aberrations uas tuaj yeem cuam tshuam qhov zoo ntawm peripheral zeem muag dhau a tsom iav lens : Oblique Astigmatism. Fais fab yuam kev. kheej kheej Aberration.

Ib yam li ntawd, tib neeg nug, dab tsi yog lens aberrations?

Hauv optics, aberration yog cov cuab yeej ntawm optical systems xws li lo ntsiab muag uas ua rau lub teeb nthuav tawm thoob plaws qee thaj tsam ntawm qhov chaw tsis yog tsom mus rau qhov taw tes. Aberrations ua rau cov duab tsim los ntawm a lens yuav tsum tau qhov muag plooj lossis cuam tshuam, nrog rau qhov xwm txheej sib txawv nyob ntawm seb hom twg kev tsis ncaj ncees.

Ib yam li ntawd, lub zeem muag Starburst puas tuaj yeem kho tau? Vim lawv qhov xwm txheej nyuaj, cov kev hloov pauv no tsis tuaj yeem ua kho nrog tsom iav qhov muag tas li thiab feem ntau cov iav qhov muag. Cov kev hloov pauv no tau ua rau pom kev nyuaj thaum hmo ntuj, ci, halos, qhov muag plooj, hnub qub qauv los yog ob npaug pom kev (diplopia).

Ua li no, yam sib txawv ntawm kev tsis sib haum yog dab tsi?

Muaj 6 hom optical aberration:

• Astigmatism.
• Chromatic Aberration.
• Coma.
• Distortion.
• Field Curvature.
• Spherical Aberration.

Yuav ua li cas koj txo aberrations?

Nov yog qee qhov kev qhia kom txo tau chromatic aberration hauv-lub koob yees duab:

1. zam qhov sib txawv siab scenes;
2. ua kom pom tseeb kom txo qis LoCA plooj, ua rau nws zoo li me dua;
3. nqis koj lub lens los ntawm 1 nres lossis 2, piv txwv li, los ntawm kev siv me me apertures, tshem LoCA;
