Kwicandelo le-precision optics kunye ne-metrology, ukufikelela kwindawo ezinzileyo nengenazo iintshukumo kusisiseko sokulinganisa okuthembekileyo. Phakathi kwazo zonke iinkqubo zenkxaso ezisetyenziswa kwiilebhu nakwiindawo zoshishino, iqonga elihambayo lomoya obonakalayo—elaziwa njengetafile yokwahlula iintshukumo ezibonakalayo—lidlala indima ebalulekileyo ekuqinisekiseni ukuchaneka okuphezulu kwezixhobo ezifana nee-interferometers, iinkqubo ze-laser, kunye noomatshini bokulinganisa abadibeneyo (ii-CMMs).
Ulwakhiwo lobunjineli bePlatform ye-Optical
Iqonga elibonakalayo elisemgangathweni ophezulu liqulathe isakhiwo sehoneycomb esenziwe ngentsimbi epheleleyo, esenzelwe ukuqina okugqwesileyo kunye nokuzinza kobushushu. Iipleyiti eziphezulu nezisezantsi, eziqhele ukuba yi-5 mm ubukhulu, zibotshelelwe kwisiseko sehoneycomb esenziwe ngomatshini ochanekileyo esenziwe ngeeshiti zentsimbi eziyi-0.25 mm, zenza isakhiwo esilinganayo nesiyi-isotropic. Olu yilo lunciphisa ukwanda kunye nokufinyela kobushushu, luqinisekisa ukuba iqonga lihlala lithe tyaba nokuba kukho ukuguquguquka kobushushu.
Ngokungafaniyo nee-aluminium okanye ii-composite cores, ulwakhiwo lwe-honeycomb yentsimbi lunika ukuqina okuhlala kusenzeka kubunzulu bayo, ngaphandle kokufaka uguquko olungafunekiyo. Iindonga ezisecaleni zenziwe ngentsimbi, nto leyo ephelisa ukungazinzi okunxulumene nokufuma—ingxaki edla ngokubonakala kumaqonga enziwe ngezinto ezixutyiweyo. Emva kokugqitywa nokupholishwa komphezulu ngokuzenzekelayo, i-tabletop ifikelela kwi-sub-micron flatness, nto leyo enika umphezulu ofanelekileyo wokuhlanganisa i-optical kunye nezixhobo ezichanekileyo.
Uvavanyo lokulinganisa ngokuchanekileyo kunye noVavanyo lokuthobela imithetho
Ngaphambi kokuba uphume kumzi-mveliso, iqonga ngalinye elihambayo lomoya obonakalayo livavanywa uthotho lokungcangcazela kunye nokuhambelana nomthetho. Ihamile ye-pulse isebenzisa amandla alawulwayo kumphezulu weqonga ngelixa izinzwa zirekhoda impendulo yokungcangcazela ephumayo. Imiqondiso iyahlalutywa ukuvelisa i-frequency response spectrum, enceda ekumiseleni i-resonance yeqonga kunye nokusebenza kwayo ngokwahlukeneyo.
Ezona milinganiselo zibalulekileyo zithathwa kwiikona ezine zeqonga, njengoko la manqaku emele imeko embi kakhulu yokuthobela imithetho. Imveliso nganye inikwa umjikelo wokuthobela imithetho kunye nengxelo yokusebenza, ukuqinisekisa ukucaca ngokupheleleyo kweempawu eziguqukayo zeqonga. Eli nqanaba lovavanyo lidlula iindlela zemveli zoshishino, linika abasebenzisi ukuqonda okuneenkcukacha ngokuziphatha kweqonga phantsi kweemeko zokusebenza zokwenyani.
Indima Yokwahlulwa Kokungcangcazela
Ukuzihlukanisa kokungcangcazela kungundoqo woyilo lweqonga le-optical. Ukungcangcazela kuvela kwimithombo emibini ephambili—ngaphandle nangaphakathi. Ukungcangcazela kwangaphandle kuvela emhlabeni, njengeenyawo, oomatshini abakufutshane, okanye isandi solwakhiwo, ngelixa ukungcangcazela kwangaphakathi kuvela ekuhambeni komoya, iinkqubo zokupholisa, kunye nokusebenza kwesixhobo ngokwaso.
Iqonga elijikelezayo lomoya liyazahlula zombini ezi ntlobo. Imilenze yalo yokuxhoma umoya ifunxa kwaye inciphise ukungcangcazela kwangaphandle okudluliselwa kumgangatho, ngelixa umaleko wokufunxa umoya othwala umoya phantsi kwetafile uhluza ingxolo yangaphakathi yoomatshini. Zidibene, zakha isiseko esizolileyo nesizinzileyo esiqinisekisa ukuchaneka kokulinganisa okuchanekileyo kunye novavanyo.
Ukuqonda Ubuninzi Bendalo
Yonke inkqubo yoomatshini ine-frequency yendalo—i-frequency apho idla ngokungcangcazela xa iphazamiseka. Le parameter inxulumene ngokusondeleyo nobunzima kunye nokuqina kwenkqubo. Kwiinkqubo zokwahlukanisa i-optical, ukugcina i-frequency yendalo ephantsi (ngesiqhelo engaphantsi kwe-2–3 Hz) kubalulekile, njengoko ivumela itheyibhile ukuba yahlukanise ukungcangcazela kwendalo ngokufanelekileyo endaweni yokuyikhulisa. Ukulinganisela phakathi kobunzima, ukuqina, kunye nokufuma kumisela ngokuthe ngqo ukusebenza kakuhle kunye nokuzinza kwenkqubo yokwahlukanisa.
Ubuchwepheshe bePlatform yokudada emoyeni
Iiplatifomu zanamhlanje ezidada emoyeni zingahlulwahlulwa zibe zii-XYZ linear air bearing stages kunye nee-rotary air bearing platforms. Eyona nto iphambili kwezi nkqubo yindlela yokuthwala umoya, enika intshukumo engashukumiyo exhaswa yifilimu encinci yomoya ocinezelweyo. Ngokuxhomekeke kwisicelo, ii-air bearing zinokuba ziintlobo ezithe tyaba, ezithe tyaba, okanye ezizii-spindle.
Xa kuthelekiswa nezikhokelo zomgca we-mechanical linear, ii-air bearings zibonelela ngokuchaneka kwentshukumo ye-micron-level, ukuphindaphindwa okugqwesileyo, kunye nokungagugi koomatshini. Zisetyenziswa kakhulu ekuhlolweni kwe-semiconductor, i-photonics, kunye nezicelo ze-nanotechnology, apho ukuchaneka kwe-sub-micron kunye nokuzinza kwexesha elide kubalulekile.
Ukugcinwa kunye nobude bexesha elide
Ukugcina iqonga elijikelezayo lomoya obonakalayo kulula kodwa kubalulekile. Gcina umphezulu ucocekile kwaye ungenazo iingcola, jonga rhoqo umbane okanye ungcoliseko, kwaye uphephe iimpembelelo ezinkulu etafileni. Xa igcinwe kakuhle, itafile echanekileyo yokukhanya inokusebenza ngokuthembekileyo amashumi eminyaka ngaphandle kokonakala kokusebenza.
