Qhov sib txawv ntawm lub tshuab hluav taws xob thiab lub tshuab ntsuas digital
Electron microscope, hu ua electron microscope, yog raws li lub hauv paus ntsiab lus ntawm electron optics, siv electron beams thiab electron lo ntsiab muag es tsis txhob ntawm beams thiab optical lo ntsiab muag los duab cov qauv zoo ntawm cov teeb meem ntawm heev magnifications. Electron microscopes hloov lub teeb pom kev nrog electron ntws thiab tswj los ntawm magnetic teb. Hloov cov lo ntsiab muag, cia cov lus tsa suab ntawm electrons hloov photons, yog li koj tuaj yeem pom cov khoom me dua li cov tshuab kho qhov muag pom. Nws qhov magnification yog qhov loj, feem ntau kaum tawm txhiab zaus.
Lub tshuab ntsuas digital siv lub lens kho qhov muag los hloov cov duab rau hauv cov teeb liab analog los ntawm CCD lossis CMOS duab sensor, thiab xa mus rau lub computer. Qhov tseeb, cov cuab yeej siv duab digital tau ntxiv rau lub tshuab ntsuas qhov muag, uas tuaj yeem tso ncaj qha tso saib cov duab tsim los ntawm lub tshuab tsom rau ntawm lub khoos phis tawj lub vijtsam (hauv tau tsim "digital microscope" zoo ib yam li cov menyuam yaus cov khoom ua si). Nws tseem yog optical microscope, thiab lub hauv paus ntsiab lus imaging ntawm electron microscope yog qhov txawv. Ntawm no peb yuav tsum paub qhov txawv ntawm kev daws teeb meem thiab kev nthuav dav. Thaum ib qho khoom me me loj thiab ua duab, nws qhov kev daws teeb meem siab tshaj plaws nyob ntawm lub wavelength ntawm lub teeb pom kev yoj. Qhov luv luv wavelength, qhov kev daws teeb meem siab dua. Lub tshuab hluav taws xob siv hluav taws xob siv X-ray duab nrog lub wavelength luv dua li qhov pom pom zoo tib yam. Tau kawg, nws muaj kev daws teeb meem siab heev, thaum qhov loj ntawm "digital microscopes" tuaj yeem loj heev, tab sis qhov kev daws teeb meem tsis tuaj yeem txhim kho.
