Ntụnye aka LIT-6 nke nkenke

Nkọwa Dị Mkpirikpi:

Ngwa a na-ejikọta Michelson interferometer, Fabry-Perot interferometer, na Twyman-Green interferometer n'otu ikpo okwu. Nhazi dị egwu na nhazi nke ngwa ahụ nwere ike ibelata oge nhazi nnwale nke ukwuu ma melite arụmọrụ nke nnwale ahụ. N'otu oge ahụ, a na-edozi akụkụ nhazi niile na obere ikpo okwu dị arọ, nke nwere ike igbochi mmetụta nke ịma jijiji na nnwale ahụ nke ọma. Michelson, Fabry Perot, prism na nnyonye anya lenses n'etiti ụdị anọ nwere ike ịgbanwe ngwa ngwa, ọrụ dị mfe, nsonaazụ ziri ezi, ọdịnaya nnwale bara ụba, bụ ngwa zuru oke iji mee nnwale nnyonye anya njikọta.
