I-Diffraction ye-optical element luhlobo oluthile lwe-optical element ene-high diffraction performance, esekelwe kwithiyori ye-diffraction yamaza okukhanya kwaye isebenzisa uyilo oluncediswa yikhompyutha kunye nenkqubo yokwenziwa kwetshiphu ye-semiconductor ukubethelela inyathelo okanye ulwakhiwo oluqhubekayo lokunceda kwi-substrate (okanye ngaphezulu). yesixhobo sokukhanya semveli). Izinto ezibonakalayo ezidityanisiweyo zincinci, zilula, zincinci ngobukhulu, zinefuthe eliphezulu le-diffraction, iidigri ezininzi zokuyila inkululeko, ukuzinza okuhle kwe-thermal kunye neempawu ezizodwa zokusasazeka. Ziyizinto ezibalulekileyo zezixhobo ezininzi ze-optical. Ekubeni i-diffraction ihlala ikhokelela ekuthintelweni kwesisombululo esiphezulu se-optical system, i-optical optics yendabuko ihlala izama ukunqanda iziphumo ezibi ezibangelwa yimpembelelo ye-diffraction de kube yi-1960s, kunye nokuveliswa kunye nokuveliswa ngempumelelo kwe-analog holography kunye nehologram yekhompyutheni kunye nomzobo wesigaba obangele utshintsho olukhulu kwingqondo. Ngeminyaka yoo-1970, nangona itekhnoloji yehologram yekhompyuter kunye nedayagram yesigaba yayisiya igqibelele ngakumbi, kwakunzima ukwenza izinto zesakhiwo sehyperfine ezinobunkunkqele obuphezulu be-diffraction kubude obubonakalayo nakufutshane ne-infrared wavelengths, ngaloo ndlela kunciphisa usetyenziso olusebenzayo lwezinto ezibonakalayo. . Kwiminyaka yoo-1980, Iqela lophando elikhokelwa yi-WBVeldkamp esuka kwi-MIT Lincoln Laboratory e-United States yaqala yazisa itekhnoloji ye-lithography ye-VLSI yokuvelisa kwimveliso ye-diffractive optical components, kwaye yaphakamisa ingcamango "ye-binary optics". Emva koko, iindlela ezahlukeneyo zokucwangcisa ezintsha ziyaqhubeka nokuvela, kubandakanywa ukuveliswa kwezinto eziphezulu kunye ne-multifunctional diffraactive optical components. Ngaloo ndlela kukhuthazwa kakhulu ukuphuhliswa kwezinto ezibonakalayo ezibonakalayo.
Ukusebenza kwe-diffraction ye-diffractive optical element
Ukusebenza kwe-Diffraction yenye yezalathisi ezibalulekileyo zokuvavanya i-diffractive optical elements kunye ne-diffraction diffraction systems kunye ne-diffractive optical elements. Emva kokuba ukukhanya kudlule kwi-diffractive optical element, i-multiple diffraction orders iya kuveliswa. Ngokuqhelekileyo, kuphela ukukhanya komyalelo we-diffraction oyintloko kunikwa ingqalelo. Ukukhanya kweminye imiyalelo ye-diffraction kuya kwenza ukukhanya okulahlekileyo kwinqwelomoya yomfanekiso we-diffraction order kunye nokunciphisa umahluko wendiza yomfanekiso. Ke ngoko, ukusebenza kwe-diffraction ye-diffraction optical element ichaphazela ngokuthe ngqo umgangatho wokucinga we-diffractive optical element.
Ukuphuhliswa kwezinto ezibonakalayo ze-diffractive
Ngenxa ye-diffractive optical element kunye ne-flexible control wave front, inkqubo ye-optical kunye nesixhobo siphuhlisa ukukhanya, i-miniaturized kwaye idibeneyo. Kuze kube ngoo-1990, uphononongo lwezinto ezidityanisiweyo ze-optical ziye zaba phambili kwibala le-optical field. Ezi zixhobo zinokusetyenziswa ngokubanzi ukulungiswa kwe-laser wavefront, ukwenza iprofayili ye-beam, i-beam array generator, i-optical interconnection, i-optical parallel calculation, i-satellite optical communication njalo njalo.
