1 Teb. 1. xaj by. 3. Canon cov Diffraction Kho yog lub koob yees duab + lens tshwj xeeb kho uas siv ib tug profile ntawm lub lens siv los ameliorate cov teebmeem ntawm kev txawv txav tshwm sim los ntawm apertures nqaim dua li Diffractive Limited Aperture rau ib lub koob yees duab / sensor.

Yog li ntawd, dab tsi yog lens diffraction?

LENS DIFFRACTION & PHOTOOGRAPHY. Diffraction yog qhov cuam tshuam kho qhov muag uas txwv tag nrho cov kev daws teeb meem ntawm koj qhov kev yees duab - txawm tias muaj pes tsawg megapixels koj lub koob yees duab yuav muaj. Nws tshwm sim vim lub teeb pib tawg los yog "diffract" thaum dhau los ntawm qhov qhib me me (xws li koj lub koob yees duab aperture).

Ib tug kuj yuav nug, peb tuaj yeem tiv thaiv qhov txawv ntawm kev yees duab li cas? Txawm hais tias koj tsis tuaj yeem hla txoj cai ntawm physics, muaj ib qho txoj kev kom tsis txhob diffraction hauv koj duab : siv lub aperture loj dua. Yog tias koj xav tau qhov tseeb tshaj plaws yees duab , qhov no tsuas yog txoj kev zam cov teebmeem ntawm kev txawv txav.

Yog li ntawd, dab tsi yog qhov ua rau diffraction hauv lo ntsiab muag?

Lens diffraction yog ua rau los ntawm overlapping wavelengths ntawm lub teeb yuam los ntawm tib lub me me qhib hauv a lens . Lub overlapping nthwv dej cuam tshuam nrog ib leeg los ntawm kev tshem tawm qhov pom kev wavelengths.

Diffraction cuam tshuam li cas rau kev daws teeb meem?

Diffraction ua rau cov ntsiab lus ntawm lub teeb uas nyob ze ua ke kom pom qhov muag plooj rau hauv ib qho chaw: nws teeb tsa qhov txwv ntawm qhov daws teeb meem nrog qhov twg tuaj yeem pom. yog hais tias lub teeb hla dhau ib ncig aperture.
