Isithombe Esivelele se-LIT-6 Precision Interferometer

I-Interferometer Eqondile ye-LIT-6

Incazelo emfushane:

Le mishini ihlanganisa i-interferometer kaMichelson, i-interferometer kaFabry-Perot, kanye ne-interferometer kaTwyman-Green epulatifomu eyodwa. Umklamo ohlakaniphile kanye nesakhiwo esihlanganisiwe sale thuluzi kunganciphisa kakhulu isikhathi sokulungisa ukuhlola futhi kuthuthukise ukusebenza kahle kokuhlola. Ngesikhathi esifanayo, zonke izingxenye zesakhiwo zinamathele epulatifomu encane esindayo, okungavimbela ngempumelelo umthelela wokudlidliza ekuhlolweni. UMichelson, uFabry Perot, ukuphazamiseka kwe-prism kanye nelensi phakathi kwezindlela ezine kungaguqulwa kalula, ukusebenza okulula, umphumela onembile, okuqukethwe kokuhlola kucebile, kuyithuluzi elifanele lokwenza ukuhlolwa kokuphazamiseka okuhlanganisiwe.

Sithumelele i-imeyili

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo
