I-Diffraction Optical element iwuhlobo lwesici sokubona esisebenza kahle kakhulu, esisekelwe embonweni we-diffraction wegagasi lokukhanya futhi sisebenzisa umklamo osizwa ngekhompiyutha kanye nenqubo yokukhiqiza i-semiconductor chip ukuze kugcizelelwe isinyathelo noma isakhiwo sokusiza esiqhubekayo ku-substrate (noma ngaphezulu. yedivayisi yendabuko yokubona).Izakhi ze-optical ezihlukanisiwe zincane, zilula, zincane ngosayizi, zinokusebenza kahle kwe-diffraction, amadigri amaningi okuklama enkululeko, ukuzinza okuhle kokushisayo nezici ezihlukile zokuhlakazeka.Ziyizingxenye ezibalulekile zezinsimbi eziningi ze-optical.Njengoba i-diffraction ihlale iholela ekunciphiseni ukulungiswa okuphezulu kwesistimu yokubona, amehlo endabuko ahlala ezama ukugwema imiphumela emibi ebangelwa umphumela we-diffraction kuze kube ngawo-1960, ngokusungulwa nokukhiqizwa ngempumelelo kwe-analog holography nehologram yekhompyutha kanye nomdwebo wesigaba obangele ushintsho olukhulu emqondweni.Ngawo-1970, nakuba ubuchwepheshe behologram yekhompiyutha kanye nomdwebo wesigaba babuqhubeka bungenasici, kwakusenzima ukwenza izakhi zesakhiwo se-hyperfine ezinokusebenza kahle okuphezulu kwe-diffraction kumaza abonakalayo naseduze kwe-infrared wavelength, ngaleyo ndlela kukhawulelwe uhla lokusetshenziswa okusebenzayo kwezakhi ze-optical diffractive. .Ngeminyaka yawo-1980, Iqembu locwaningo elaliholwa yi-WBVeldkamp laseMIT Lincoln Laboratory e-United States laqala lethula ubuchwepheshe be-lithography bokukhiqiza i-VLSI ekukhiqizeni izingxenye ze-diffractive optical, futhi laphakamisa umqondo "wokubona kanambambili".Ngemva kwalokho, izindlela ezintsha zokucubungula ezintsha ziyaqhubeka nokuvela, okuhlanganisa ukukhiqizwa kwezingxenye ze-optical diffractive ezisezingeni eliphezulu nezisebenzayo.Ngakho-ke kukhuthaze kakhulu ukuthuthukiswa kwezakhi ze-optical diffractive.
Ukusebenza kahle kwe-Diffraction ye-optical element ehlukile
Ukusebenza kahle kwe-Diffraction kungenye yezinkomba ezibalulekile zokuhlola ama-elementi e-diffractive optical kanye nesistimu yokubona exubile ene-diffractive optical elements.Ngemva kokuthi ukukhanya kudlule ku-elementi ye-diffractive optical, kuzokwenziwa ama-oda amaningi okushintshashintsha.Ngokuvamile, ukukhanya kuphela kwe-diffraction order okunakwa kukho.Ukukhanya kwamanye ama-diffraction oda kuzokwakha ukukhanya okunhlanhlatha endizeni yesithombe yohlelo oluyinhloko lokwehluka futhi kunciphise ukugqama kwendiza yesithombe.Ngakho-ke, ukusebenza kahle kwe-diffraction ye-optical element ehlukanisiwe kuthinta ngokuqondile ikhwalithi yokucabanga ye-diffraactive Optical element.
Ukuthuthukiswa kwezici ze-optical diffractive
Ngenxa ye-diffractive optical element kanye nokulawula kwayo okuguquguqukayo okungaphambili kwegagasi, isistimu yokubona kanye nedivayisi kuthuthukela ekukhanyeni, okwenziwe nge-miniaturized futhi kuhlanganiswe.Kuze kube yiminyaka yawo-1990, ukucwaninga kwezinto ezibonakalayo ze-diffractive sekuhamba phambili emkhakheni we-optical field.Lezi zingxenye zingasetshenziswa kabanzi ekulungisweni kwe-laser wavefront, ukwakhiwa kwephrofayili ye-beam, i-generator ye-beam array, uxhumano lwe-optical, ukubala kwe-optical parallel, ukuxhumana kwe-satellite optical nokunye.
