Ma te whakahaere i te wahanga o te kurupae kurupae i roto i te rarangi kurupae, ka taea e te hangarau huānga whatu whatu te mohio ki te hanga ano, ki te whakarite tika ranei o te rererangi isopic kurupae.Kei a ia nga painga o te iti o te rōrahi me te papatipu o te punaha, te tere whakautu tere me te pai o te kurupae.
Ko te maataapono mahi o te hangarau huānga whatu whatu ko te neke tika (te whakaroa ranei) te tohu o te huānga turanga kua whakaritea kia rite ki tetahi ture kia whiwhi i te paheketanga o te kurupae huinga.E ai ki te whakamaramatanga o runga ake nei, kei roto i te hangarau whakahiato ohanga te hangarau whakapoipoi kurupae nui-koki mo nga raupapa tukunga kurupae me te hangahanga hangarau whakaata whakararu i te telescope mo te atahanga taumira teitei o nga whaainga tawhiti.
Mai i te tirohanga o te tukunga, ko te raupapa o nga waahanga whatu hei whakahaere i te wahanga o te kurupae kua tukuna, kia mohio ai koe ki te paheketanga katoa o te kurupae huinga, ki te utu hapa hapa ranei.Ko te maataapono taketake o te huānga wahanga whatu e whakaatuhia ana i te FIG.1. FIG.Ko te 1 (a) he huānga waihanga koretake, ara, he "raupapa" anake kaore he "raupapa-waahanga".Ko te Whakaahua 1 (b) ~ (d) e whakaatu ana i nga ahuatanga mahi rereke e toru o te huānga whatu whatu (ara, te huānga waihanga tuitui).
Ko te punaha whakahiato kore e kawe noa i te tuunga hiko o te kurupae hurangi me te kore e whakahaere i te wahanga o te kurupae huinga.Ko tana puna marama he maha nga lasers me nga roangaru rereke, ka whakatauhia te rahi o te waahi tawhiti ma te rahi o te huinga huinga whakawhiti, motuhake mai i te maha o nga huānga huinga, te aperture rite o te raupapa me te tauwehenga mahi o te raupapa kurupae, no reira e kore e taea te tatau hei hurangi wahanga i roto i te tikanga pono.Heoi, kua whakamahia whanuitia te punaha whakahiato kore na te mea he ngawari te hanga, he iti te hiahia mo te mahi puna marama me te mana whakaputa nui.
Mai i te tirohanga o te whiwhinga, ka whakamahia te raupapa whatu whatu i roto i te atahanga taumira teitei o nga whaainga mamao (FIG. 2).Kei te tito i te raupapa karu, te huinga retarder wahanga, te whakakotahi kurupae me te taputapu atahanga.Ka whiwhi te hononga matatini o te puna whaainga.Ko te ahua o te whaainga ka tatauhia kia rite ki te kaupapa Fanssert-Zernick.Ko tenei tikanga e kiia ana ko te tikanga whakamaarama pokanoa, koinei tetahi o nga tikanga hangahanga aperture atahanga.Mai i te tirohanga o te hanganga o te punaha, he rite tonu te hanganga o te punaha whakaahua interferometric me te punaha whakangao raupapa, engari he rereke te ahunga whakawhiti ara whatu i roto i nga tono e rua.
