Izakhiwo zikagesi kanye nokusetshenziswa kwamafilimu edayimane
Idayimani ine-bandwidth engavunyelwe, ukuhamba okuphezulu kwenethiwekhi, ukuqhuba kahle kokushisa, izinga eliphezulu lokugeleza kwama-electron, ukuqina okuncane kwe-dielectric, i-voltage ephezulu yokuqhekeka kanye nokuhamba kwemigodi yama-electron, njll. I-voltage yayo yokuqhekeka iphakeme kakhulu kune-Si ne-GaAs, futhi ukuhamba kwayo kwama-electron nemigodi kukhulu kakhulu kune-monocrystalline silicon CA:. Ifilimu yedayimani ingasetshenziswa njengezinto ze-semiconductor zokuqonda i-broadband. Njengamanje icwaninge ngempumelelo uhlangothi lwedayimani olungaphandle kwe-silicon (umkhiqizo womphumela wekamu lomzimba kanye nesekethe ye-logic, la madivayisi angaba ngaphansi kuka-600 ℃ ngaphansi komsebenzi ojwayelekile, kudivayisi ye-semiconductor eshisa kakhulu inombono omkhulu wohlelo lokusebenza. Ngenxa yegebe elikhulu lebhendi yedayimani, ingasetshenziswa ekukhipheni ukukhanya okuluhlaza okwesibhakabhaka, ukuthola ukukhanya kwe-ultraviolet, kanye namadivayisi okuvuza okuphansi.
Izakhiwo Zokukhanya kanye Nokusetshenziswa Kwamafilimu Acwebezelayo Edayimane
Idayimane inezakhiwo ezinhle kakhulu zokukhanya, ngaphezu kokuba khona kweziqongo ezincane zokumuncwa (okubangelwa ukudlidliza kwe-phonon) ku-3 ~ 5μm, kusukela ngaphandle (225nm) kuya ku-infrared ekude (25μm) lonke uhla lwama-band, idayimane inokudlulisa okuphezulu, iyinto efanelekile yefasitela yama-laser e-infrared enamandla aphezulu kanye nama-detector. Idayimane ebhendini le-infrared lokubonakala okubonakalayo, okwenza kube ukukhiqizwa kwe-high-density, ukumelana nokugqwala ngaphambili okulayishwe yifasitela langaphandle lokukhanya, kusho ukuthi impahla efanelekile, ingasetshenziswa ekubambeni ifasitela le-infrared ngemicibisholo. Ngaphezu kwalokho, inkomba yokukhanya kwedayimane iphakeme, ingasetshenziswa njengefilimu yokubonisa ukuncipha kwebhethri lelanga. Ifilimu yedayimane yokungena kwamagagasi e-radar akulula ukuyihlanekezela, ukusetshenziswa kwalesi sici kungasetshenziswa njenge-radome, impukane kanye nemicibisholo endizeni ye-supersonic, i-head cone radar ayikwazi ukumelana nokushisa okuphezulu, futhi kunzima ukumelana namaconsi emvula asheshayo kanye nokungalungi kothuli, nge. Idayimane lenziwe nge-radome, hhayi nje kuphela ukushabalalisa ukushisa okusheshayo, ukumelana nokuguguleka kuhle, kodwa futhi lingaxazulula i-radome endizeni eshesha kakhulu ukuze imelane nenkinga yokuhlanganiswa kwezinga lokushisa eliphezulu.
Ezinye izinhlelo zokusebenza zefilimu yedayimane
Ifilimu yedayimane ine-modulus ephezulu ye-Young kanye ne-modulus elastic, evumela ukudluliselwa kwamagagasi e-acoustic acceleration ephezulu ngokuthembeka okuphezulu, futhi iwuhlobo olusha lwezinto zokwakha izihlungi zamagagasi e-acoustic acceleration ezibucayi kakhulu. Idayimane ine-modulus ephezulu yokuguquguquka kanye nesivinini sokusabalala komsindo ophezulu, futhi ingasetshenziswa njengesipikha sesandi esinokwethembeka okuphezulu somsindo wezinga eliphezulu.
Idayimane ine-modulus ephezulu yokunwebeka kanye nesivinini esikhulu sokusabalala komsindo, ngakho-ke ingasetshenziswa njengezinto zokwakheka kwe-vibration membrane ze-loudspeaker esezingeni eliphezulu.
Ngaphezu kwalokho, idayimane linokuqina okuhle kwamakhemikhali futhi limelana nokugqwala ngama-asidi anga-oxidizing emazingeni okushisa ahlukahlukene. Ingxenye yalo eyinhloko, i-carbon, iyinto engenabo ubuthi, engangcolisi engahambisani nomzimba womuntu. Ngenxa yokuthi idayimane ayisabelani negazi lomuntu kanye nolunye uketshezi lwezicubu, idayimane futhi iyinto efanelekile yezokwelapha yokufakelwa kwezinto eziphilayo, engasetshenziswa ukwenza ama-valve enhliziyo okwenziwa.
