Dab tsi yog qhov tseem ceeb uas tsim xim sib txawv ntawm qhov tsim cov khoom siv dag?
Muaj ntau qhov teeb meem cuam tshuam qhov zoo ntawm cov khoom cua dag, thiab muaj ntau yam teeb meem, ntawm cov uas cov chromatic aberration yog ib qho teeb meem zoo tib yam ntawm cov khoom cua dag, thiab xim txawv muaj ntau txoj kev qhia. Yog vim li cas rau qhov txawv xim yog tias cov khoom siv raw tsis tuaj yeem txheem lossis cov khoom siv kab xev tsis yog siv rau cov qauv, lossis cov tshuab tsis ua haujlwm raws li tus txheej txheem ntawm kev tsim.
Thawj, cov khoom tsis tsim lub chromatic aberration tag. Hloov cov khoom tshiab uas siv cov khoom siv rau hauv cov khoom seem tsis tuaj yeem tu, ob theem sib tov, ua qhov no ntawm cov khoom xyaw thiab qhov teeb meem tsim ua qhov sib txawv, sib tov nrog cov khoom tshiab rub rub cov xim txawv.
Thib ob, tib neeg tsis txhob lo yeeb yam - hauv paus xim sib txawv. Nws yog hais txog cov xim txawv ntawm ob peb txheej ntawm txoj kab xaim ncaj, uas yog feem ntau tshwm sim los ntawm qhov chaw ntawm lub taub hau, nro, cov tsho khi thiab lwm yam kev sib txuas hauv txoj kev xaim hlau.
Thib peb, qhov kev vuab tsuab ua qhov muag pom txawv. Lub curving ntawm nyom feem ntau yog los ntawm inconsistency ntawm shrinkage tus nqi ntawm ncaj nyom. Lub shrinkage tus nqi yuav ua tiav los ntawm kev kho qhov kub ntawm cov cua ntsawj ntshab cub, qhov kub ntawm qhov chaw qhov cub thiab qhov sib piv.
Qhov thib plaub, cov xov kab uas tsis sib xws ua rau cov qib chromatic aberration. Uneven nyom curvature tuaj yeem ua rau tsis sib npaug, tsis sib txig, ua rau qhov muag pom txawv. Lub curvature ntawm curved nyom yuav tsum yog uniform thiab uniform, uas yuav tsum tau hais tias kev kos duab thiab mis yog tsim nyog, thiab qhov kub thiab siab ntawm lub tshuab bending yog ruaj khov.
Cov xim txawv los ntawm kev tsis twist thiab twist. Kev twist ntawm twister yog twist, thiab twist ntawm qhov ntev ntawm chav tsev yog hu ua twist, thiab twist yog cov kev taw qhia tias cov nyom fiber qhia thaum cov nyom yog sib ntswg. Lub twist ntawm khoom neeg tsim nyom muaj zoo kawg nkaus lub hwj chim rau ntawm cov tsos ntawm cov khoom neeg tsim nyom.
Qhov thib rau, ntaub pua plag yog tais, daim npog lub ntsej muag quav ua cov chromatic aberration. Lub cim ntawm cov quav feem ntau yog vim tsis ua hauj lwm kom ncav cuag tus txheej txheem thaum lub kua nplaum yog ziab hauv qab daim ntaub. Cov quav ntawm daim pam ua rau daim pam mus quav, thiab qhov tsis zoo ntawm cov nyom tuaj yeem ua rau daim pam folding.
Xya, sib txawv ntawm cov khoom siv raw khoom tsim cov khoom siv dag cov khoom ua si, paving rau tib lub tsev kawm ntawv yuav tsim xim txawv. Cov khoom siv ntawm cov khoom sib txawv sib txawv yuav tsis zoo ib yam, thiab yuav muaj ntau qhov sib txawv ntawm qhov txawv, uas yuav ua rau qhov sib txawv ntawm cov xim ntawm cov nyom.
