Vim li cas ho tsis tau electron microscope hloov optical microscope?
Lub tshuab ntsuas hluav taws xob yog ua raws li lub hauv paus ntsiab lus ntawm electron optics. Electron beams thiab electron lo ntsiab muag yog siv es tsis txhob ntawm lub teeb beams thiab optical lo ntsiab muag, thiaj li hais tias cov qauv zoo ntawm cov teeb meem yuav imposed nyob rau hauv ib tug heev magnification. Txawm hais tias nws qhov kev daws teeb meem zoo dua li ntawm optical microscope, nws yog ib qho nyuaj rau electron microscope los saib xyuas cov kab mob uas muaj sia nyob vim tias nws yuav tsum tau ua haujlwm hauv lub tshuab nqus tsev, thiab cov irradiation ntawm electron beam yuav ua rau cov qauv lom, yog li nws tsis tuaj yeem hloov tag nrho. optical microscope, thiab lawv cov nqi thiab kev ua haujlwm tsim nyog sib txawv. Kuv vam tias kuv cov lus teb yuav pab tau koj.
Yog vim li cas vim li cas electron microscope tsis tuaj yeem hloov kho qhov muag microscope yog li hauv qab no:
1. Lub tshuab ntsuas hluav taws xob yog nyob rau ntawm lub tshuab ntsuas qhov muag, thiab cov khoom siv xws li CCD, cov tshuaj ntsuam xyuas lossis lub khoos phis tawj ntxiv. Qhov no tsuas tuaj yeem hais tias yog lub tshuab tsom iav video. Hauv tag nrho cov txheej txheem duab, CCD hloov lub qhov muag ntawm tib neeg. Vim hais tias nyob rau hauv video imaging, hluav taws xob amplification belongs rau virtual amplification, thiab nyob rau hauv cov nqe lus ntawm pixels, photosensitive nyhuv thiab lwm yam, nws txawv dhau ntawm tib neeg ob lub qhov muag, yog li nws txawv dhau los ntawm qhov pom kev siv tshuab tsom;
2. Tseem muaj qhov tseem ceeb tshaj plaws. CCD belongs rau lub dav hlau imaging, tab sis tib neeg lub qhov muag, tshwj xeeb tshaj yog kev soj ntsuam binocular, yuav muaj ib tug muaj zog stereoscopic nyhuv, uas yog vim li cas vim li cas qhov sib txawv qhov sib txawv ntawm qhov tob ntawm lawv yog heev loj;
3. Electron microscopes feem ntau qhia tau hais tias scanning electron microscopes, uas zoo dua li cov tshuab kho qhov muag zoo tib yam, tab sis lawv tsis tshua siv hauv kev lag luam vim lawv cov nqi siab.
