Hom duab twg yog tsim los ntawm daim iav convex?
A Acrylic convex iav, tseem hu ua daim ntawv fisheye los yog daim iav divergent, yog ib daim iav nkhaus nrog lub pob hauv nruab nrab thiab cov duab tshwj xeeb.Lawv feem ntau siv rau ntau yam kev siv xws li kev soj ntsuam kev ruaj ntseg, kev saib xyuas lub tsheb qhov muag tsis pom kev, thiab txawm tias lub hom phiaj kho kom zoo nkauj.Ib qho ntawm cov yam ntxwv tseem ceeb ntawm daim iav convex yog hom duab uas lawv tsim.
Thaum lub teeb rays tsoo adaim iav, lawv diverge los yog kis tau vim yog cov duab ntawm daim iav.Qhov no ua rau lub teeb pom kev tshwm sim los ntawm qhov chaw virtual tom qab daim iav (hu ua focal point).Lub focal point yog nyob rau tib sab ntawm cov khoom yog reflected.
Txhawm rau nkag siab txog hom duab tsim los ntawm daim iav convex, nws yog ib qho tseem ceeb kom nkag siab cov ntsiab lus ntawm cov duab tiag thiab virtual.Daim duab tiag tiag yog tsim thaum lub teeb rays converge rau ntawm ib qho taw tes thiab tuaj yeem tso rau ntawm qhov screen.Cov duab no tuaj yeem pom thiab ntes ntawm ib qho screen lossis nto.Ntawm qhov tod tes, ib daim duab virtual yog tsim thaum lub teeb rays tsis tau converge tab sis tshwm sim diverge los ntawm ib qho taw tes.Cov duab no tsis tuaj yeem tso rau ntawm qhov screen, tab sis tus neeg saib xyuas tuaj yeem pom lawv los ntawm daim iav.
Convex daim iav ib daim duab virtual yog tsim.Qhov no txhais tau hais tias thaum ib yam khoom muab tso rau pem hauv ntej ntawm adaim iav convex,cov duab tsim zoo li nyob tom qab daim iav, tsis zoo li thaum daim duab tsim nyob rau hauv pem hauv ntej ntawm daim iav nyob rau hauv lub tiaj tus los yog concave daim iav.Cov duab virtual tsim los ntawm daim iav convex yog ib txwm upright, txhais tau tias nws yuav tsis rov qab los yog flipped.Nws qhov loj me kuj tseem txo qis piv rau qhov khoom tiag.
Qhov loj ntawm daim duab virtual nyob ntawm qhov kev ncua deb ntawm cov khoom thiab daim iav convex.
Raws li cov khoom txav los ze rau ntawm daim iav, cov duab virtual ua me dua.Ntawm qhov tsis sib xws, thaum cov khoom txav mus deb, cov duab virtual yuav loj dua.Txawm li cas los xij, cov duab tsim los ntawm daim iav convex yuav tsis tuaj yeem nthuav dav tshaj qhov loj ntawm qhov khoom tiag tiag.
Lwm yam ntxwv ntawm daim duab tsim los ntawm adaim iavyog tias nws muab kev pom dav dav dua li daim iav tiaj tus lossis concave.Lub convex zoo ntawm daim iav tso cai rau nws kom muaj kev cuam tshuam lub teeb nyob rau hauv ib cheeb tsam loj, uas ua rau ib tug dav dav ntawm kev pom.Qhov no yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov ntawv thov xws li lub tsheb qhov muag tsis pom qhov tsom iav, qhov twg tus neeg tsav tsheb xav tau lub kaum sab xis dav dua kom pom cov tsheb tuaj ntawm sab.
