Incazelo

Le mishini ihlanganisa i-interferometer kaMichelson, i-interferometer ye-Fabry-Perot, ne-interferometer ye-Twyman-Green endaweni eyodwa. Idizayini ehlakaniphile nokwakheka okuhlanganisiwe kwensimbi kungasinciphisa kakhulu isikhathi sokulungiswa kokuhlola futhi kuthuthukise ukusebenza kahle kokuhlolwa. Ngasikhathi sinye, zonke izingxenye zesakhiwo zigxilile kupulatifomu encane esindayo, engavimba ngempumelelo umthelela wokudlidliza esivivinyweni. UMichelson, uFabry Perot, ukuphazanyiswa kwe-prism kanye nelensi phakathi kwezinhlobo ezine kungaguqulwa kalula, ukusebenza okulula, umphumela onembile, okuqukethwe kokuhlola kucebile, kuyithuluzi elihle lokwenza inhlanganisela yokuphazamiseka kokuhlolwa.

Ukuhlolwa

1. Ukubhekwa kwemishayo emibili

2. Ukuqaphela okulinganayo kokuthambekela

3. Ukuqaphela okulingana nobukhulu obulinganayo

4. Ukubukwa kwemiphetho emhlophe

5. Isilinganiso se-Wavelength se-Sodium D-lines

6. Isilinganiso sokuhlukaniswa kwe-Wavelength se-Sodium D-lines

7. Ukukalwa kwenkomba yomoya ekhanyayo

8. Kukalwa kwenkomba ekhombayo yocezu olusobala

9. Ukubhekwa kokugxambukela kwe-Multi-beam

10. Ukukala kwe-He-Ne laser wavelength

11. Ukuthikamezeka kwemiphetho yokubheka imigqa ye-Sodium D

12. Ukukhombisa umgomo we-interferometer ye-Twyman-Green
