LIT-6 Precision Interferometer
Tsananguro
Ichi chishandiso chinobatanidza Michelson interferometer, Fabry-Perot interferometer, uye Twyman-Green interferometer mune imwe chikuva. Iyo yekuchenjera dhizaini uye yakasanganiswa mamiriro echiridzwa inogona kudzora zvakanyanya kuyedza yekugadzirisa nguva uye nekuvandudza kugona kwekuyedza. Panguva imwecheteyo, ese masisitimu ezvikamu akagadzika pane inorema diki chikuva, iyo inogona kunyatso kudzivirira kukanganisa kwe vibration pane kuyedza. Michelson, Fabry Perot, chishongedzo uye kupindirana kwema lens pakati pemamodhi mana anogona kushandurwa zviri nyore, mashandiro ari nyore, mhedzisiro chaiyo, zvemukati zvekuyedza zvakapfuma, chimbo chakakodzera kuita kusangana kwekukanganisa kuyedza.
Kuedza
1. Mbiri-danda Kupindirana kwekutarisa
2. Kuenzana-kurerekera kwemucheto kucherechedza
3. Kuenzana-ukobvu mucherechedzo
4. Muchena-mwenje kutarisisa
5. Kuyera kweWavelength yeSodium D-mitsara
6. Wavelength kupatsanurwa kuyerwa kweSodium D-mitsara
7. Kuyerwa kweiyo refractive indekisi yemhepo
8. Kuyerwa kweiyo inonongedzera index yeiyo yakajeka slice
9. Multi-danda kupindira kucherechedzwa
10. Kuyerwa kweiyo He-Ne laser wavelength
11. Kukanganisa kupenya kwekucherechedza kweSodium D-mitsara
12. Kuratidzira musimboti weTyman-Green interferometer
