Vim li cas thiaj tsis tau siv tshuab hluav taws xob hloov lub tsom iav kho qhov muag?
Electron microscopes siv lub hauv paus ntsiab lus ntawm electron optics, hloov cov kab ci thiab cov ntsiab muag, ua duab rau cov qauv zoo ntawm kev magnification heev. Txawm hais tias nws daws teeb meem yog farior zoo dua rau cov kab mob me me, thiab kev tawm hauv hluav taws xob yuav tsum ua rau hluav taws xob kev puas tsuaj rau kev kuaj mob birples. Yog li ntawd, lawv tsis tuaj yeem hloov kho qhov tsom iav kho qhov muag tau zoo, thiab lawv cov nuj nqis thiab tsim nyog muaj ntau yam ua haujlwm kuj sib txawv. Kuv vam tias kuv cov lus teb tuaj yeem pab tau koj.
Yog vim li cas thiaj li Electron tsom iav tsom tau tsis tuaj yeem hloov kho qhov muag tsom iav yog li hauv qab no:
1. Electron tsom iav tsom tau yog ua raws Optical tsom duab thiab ntxiv cov khoom siv xws li CCD, muab cov ntxaij vab tshaus, lossis khoos phis tawj. Qhov no tsuas yog piav raws li video tsom duab duab tshiab, qhov twg CCD hloov tib neeg lub qhov muag thoob plaws cov txheej txheem kev xav. Vim tias hauv kev yees duab video, hluav taws xob hluav taws xob rau cov pixels, thiab muaj ntau yam ntawm tib neeg lub qhov muag, yog li nws txawv ntau dhau los ntawm kev pom ntawm lub tsom iav pom;
2. Lwm qhov laj thawj tseem ceeb yog CCD yog cov dav hlau kev ua kom, thaum tib neeg lub qhov muag, tshwj xeeb tshaj yog nyob rau hauv kev soj ntsuam tanetect, ua rau muaj kev paub txog peb qho. Qhov no yog vim li cas vim li cas qhov tob ntawm daim teb nyhuv ntawm ob yog loj heev piv;
3. Electron tsom tsom qhia feem ntau sawv cev raws li Electron scanning microscopes, uas muaj ntau dua cov teebmeem zoo dua li dav dav tsom iav. Txawm li cas los xij, vim lawv tus nqi siab, lawv tsis tshua siv hauv kev lag luam.
