Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab luam ntawv tuaj yeem ua tiav hauv cov kauj ruam tseem ceeb hauv qab no:
1. Optical duab
Cov khoom muaj pes tsawg leeg: Cov khoom siv kho qhov muag ntawm lub tshuab luam ntawv yog tsim los ntawm lub teeb ci, lub lens thiab daim iav.
Nws ua haujlwm li cas: Thaum cov ntaub ntawv peb yuav luam tau muab tso rau ntawm lub iav phaj ntawm lub tshuab luam ntawv, lub teeb qhov chaw emits lub teeb thiab tsom rau ntawm qhov chaw ntawm daim ntawv los ntawm lub lens thiab reflectors. Thaum lub teeb hla dhau ntawm qhov chaw ntawm cov ntaub ntawv, nws yog reflected los yog absorbed los ua ib tug optical duab. Cov txheej txheem no hloov cov duab cov ntaub ntawv ntawm qhov chaw ntawm cov ntaub ntawv mus rau hauv lub teeb liab optical.
Thib ob, them nyiaj induction
Photodrum action: Lub photodrum hauv lub tshuab luam ntawv (tseem hu ua photodrum) plays lub luag haujlwm tseem ceeb hauv cov kauj ruam no. Lub teeb-sensitive nruas yog coated nrog ib tug tshwj xeeb cov ntaub ntawv uas thaum lub teeb hits lub teeb-sensitive nruas, lub illuminated cheeb tsam poob nws nqi, thaum lub unilluminated cheeb tsam khaws cia. Nyob rau hauv no txoj kev, ib tug nqi tis coj mus rau lub optical duab yog tsim nyob rau hauv lub rhiab nruas nruas.
Thib peb, electrostatic replication
Kev hloov hluav taws xob: Tom ntej no, lub tshuab luam ntawv xa cov nqi xa tawm ntawm lub nruas photosensitive mus rau lwm qhov nruab nrab, feem ntau yog lub vev xaib nrog cov khoom siv hluav taws xob. Ib lub pas fais fab ntawm lub tshuab luam ntawv muab tus nqi zoo li qub rau lub vev xaib kom tag nrho cov khoom siv tib yam nqi. Tus nqi xa tawm ntawm lub nruas raug xa mus rau lub vev xaib, tsim kom muaj tus nqi xa tawm zoo ib yam rau thawj cov ntaub ntawv.
Plaub, kho
Cheebtsam muaj pes tsawg leeg: Qhov kho qhov feem ntau yog tsim los ntawm cov menyuam kub, kho tus neeg saib xyuas thiab xovxwm cov menyuam.
Cov txheej txheem ua haujlwm: Thaum lub vev xaib dhau los ntawm cov menyuam kub, cov menyuam kub yuav ua kom sov lub fixer, ua rau nws yaj. Lub vev xaib tom qab ntawd dhau los ntawm tus kho, uas txuas rau thaj chaw them nyiaj hauv lub vev xaib, tsim kom pom cov duab replica pom. Thaum kawg, lub vev xaib dhau los ntawm cov xovxwm cov menyuam los txhim kho lub fixer ntawm daim ntawv kom tiav cov txheej txheem replication.
