"AA lens"hais txog cov iav uas tau sib dhos ua ke siv cov thev naus laus zis Active Alignment (AA) - ib txoj kev uas feem ntau siv rau hauv kev tsim cov koob yees duab modules. Active Alignment yog ib qho txheej txheem sib dhos ua ke rau cov iav thiab cov sensors; nws tso cai rau kev sib koom ua ke ntawm lub lens nrog lub sensor duab thaum lub sijhawm tsim khoom, kom ntseeg tau tias muaj kev ua tau zoo tshaj plaws ntawm kev thaij duab.
Kev sib dhos cov koob yees duab modules muaj ntau yam khoom sib dhos, xws li lub sensor duab, lub lens tuav, thiab lub lens nws tus kheej. Cov txheej txheem sib dhos ib txwm muaj feem ntau raug txwv los ntawm kev ua haujlwm ntawm cov khoom thiab kev ua yuam kev ntawm tib neeg, uas tuaj yeem ua rau muaj kev sib sau ua ke ntawm kev hloov pauv. Cov kev tsis sib xws me me no yuav ua rau muaj teeb meem xws li cov duab tsis meej, qhov ntse tsis sib xws ntawm qhov chaw thiab ntug ntawm tus ncej, lossis qhov zoo li ntawm vignetting (cov ces kaum tsaus ntuj).
Thaum lub koob yees duab daws teeb meem nce ntxiv thiab qhov apertures loj dua, qhov yuav tsum tau ua rau qhov kev sib dhos meej dua tau dhau los ua qhov nruj dua. AA thev naus laus zis hloov pauv ntawm cov txheej txheem sib dhos passive ib txwm muaj. Los ntawm kev siv cov khoom siv tshwj xeeb, nws ua rau muaj kev hloov kho dynamic ntawm lub lens thiab lub sensor duab qhov chaw thiab lub kaum sab xis - txhua yam thaum saib xyuas daim duab hauv lub sijhawm tiag tiag. Qhov no ua kom ntseeg tau tias qhov sib phim ntawm lub lens lub optical axis nrog lub hauv paus ntawm lub sensor duab, ua tiav qhov zoo tshaj plaws tag nrho cov duab xeev, tom qab ntawd cov khoom raug ruaj khov tas mus li siv cov nplaum lossis vuam.
