Umfanekiso oPhambili we-LIT-6 Precision Interferometer

I-Interferometer echanekileyo ye-LIT-6

Inkcazo emfutshane:

Esi sixhobo sidibanisa i-interferometer kaMichelson, i-interferometer kaFabry-Perot, kunye ne-interferometer kaTwyman-Green kwiqonga elinye. Uyilo olunobuchule kunye nesakhiwo esidibeneyo sesixhobo sinokunciphisa kakhulu ixesha lokulungisa uvavanyo kwaye siphucule ukusebenza kakuhle kovavanyo. Kwangaxeshanye, zonke iindawo zesakhiwo zinamathele kwiqonga elincinci elinzima, elinokuthintela ngempumelelo impembelelo yokungcangcazela kuvavanyo. UMichelson, uFabry Perot, ukuphazamiseka kweprism kunye nelensi phakathi kweendlela ezine kunokuguqulwa ngokulula, ukusebenza okulula, iziphumo ezichanekileyo, umxholo wovavanyo utyebile, sisixhobo esifanelekileyo sokwenza uvavanyo lokuphazamiseka okudibeneyo.
