Isingeniso kuswir ikhameras
● Incazelo kanye Nezimiso Eziyisisekelo
Amakhamera we-Short-Wave Infrared (SWIR) avele njengamathuluzi abalulekile emikhakheni ehlukahlukene efana nezolimo, ezokuvikela, izimboni, nezimboni zezokwelapha. Ikhamera ye-SWIR yakhelwe ukuthola ukukhanya ebangeni le-wavelength le-SWIR lama-micrometer angu-0.9 kuya ku-2.5. Ngokungafani nokukhanya okubonakalayo, ukukhanya kwe-SWIR akubonakali ngeso lenyama, okwenza lawa makhamera akwazi ukukhiqiza izithombe eziphezulu-ezinokulungiswa okuphakeme ezimeni lapho ukuthwebula ukukhanya okubonakalayo kuzohluleka khona. Noma ngabe okokuhlolwa kwe-semiconductor, ukugadwa, noma ukuthwebula isithombe sezokwelashwa, amakhono amakhamera e-SWIR anikezela ngezinhlelo eziningi ezahlukene.
● Ukubaluleka Nezicelo
Ukubaluleka kwamakhamera e-SWIR kusemandleni awo okubona ngezinto ezi-opaque kuya ekukhanyeni okubonakalayo, njengengilazi noma ama-polymer athile. Lesi sici sibaluleke kakhulu ezinhlelweni zokusebenza ezifana nokulawula ikhwalithi ngesikhathi sokukhiqiza, lapho obunye ubuchwepheshe bokuthwebula izithombe bungase bube bufushane. Amakhamera e-SWIR aphinde avelele ekuqaphelweni kwezolimo, okuvumela ukutholwa kwamanzi kanye nempilo yezitshalo, okubalulekile ekuthuthukiseni isivuno.
Izingxenye zekhamera ye-SWIR
● Izinzwa, amalensi, ama-Photodiode Arrays
Ikhamera evamile ye-SWIR ihlanganisa izingxenye ezimbalwa ezibalulekile: inzwa, ilensi, i-photodiode array, kanye nesistimu yokuguqula. Inzwa ithola ukukhanya kububanzi be-SWIR futhi ngokuvamile yenziwe ngezinto ezifana ne-Indium Gallium Arsenide (InGaAs). Ilensi igxilisa ukukhanya kwe-SWIR okungenayo kwinzwa. I-photodiode array, ehlelwe ngephethini yegridi, inesibopho sokuthola ukushuba kwesibani se-SWIR esingenayo. Ndawonye, lezi zingxenye zidlala indima ebalulekile ekhonweni lekhamera lokuthwebula izithombe ezicacile nezinembayo.
● Conversion Systems
Uma ukukhanya sekungene kuhlelo lwe-photodiode, kudala ukushajwa kukagesi ngokulingana nokuqina kokukhanya. Lokhu kushaja kube sekuguqulelwa kusignali yedijithali ngohlelo lokuguqula lwekhamera. Lesi siginali yedijithali icutshungulwa ibe yisithombe, ngokuvamile esisikali esimpunga, lapho iphikseli ngayinye imelela khona umthunzi ohlukile wokumpunga ohambisana nokuqina kokukhanya kuleyo ndawo.
Amakhamera we-SWIR azithwebula kanjani izithombe
● Ukuthola ukukhanya ku-SWIR Range
Amakhamera e-SWIR athwebula izithombe ngokuthola ukukhanya nokuphuma kokukhanya ebangeni le-SWIR wavelength. Uma ukukhanya kwe-SWIR kudlula kulensi yekhamera, kugxilwa kuhlelo lwe-photodiode kunzwa. Iphikseli ngayinye ohlwini ikala ukushuba kokukhanya futhi yakha ingxenye yesithombe sisonke.
● Inqubo Yokwakhiwa Kwesithombe
Inqubo iqala ngokukhanya kwe-SWIR kushaya i-photodiode array, idala ukushaja okuhluka ngokuqina kokukhanya. Lokhu kukhokha kube sekuguqulelwa kufomu ledijithali, kusetshenzwe uhlelo lwekhamera ye-elekthronikhi, futhi ekugcineni kwethulwe njengesithombe. Isithombe esimpunga esikhiqiziwe sinikeza imininingwane enemininingwane, ngephikseli ngalinye elimele izinga elihlukile lokuqina kokukhanya.
Ukusetshenziswa Kwempahla Kuzinzwa ze-SWIR
● Iqhaza le-InGaAs (Indium Gallium Arsenide)
Enye yezinto ezisetshenziswa kakhulu izinzwa ze-SWIR yi-Indium Gallium Arsenide (InGaAs). Inzuzo ye-InGaAs ilele kumandla ayo ama-bandgap amancane uma kuqhathaniswa ne-silicon. Lokhu kuyivumela ukuthi imunce ama-photon anobude obude wamaza, okuyenza ilungele ukuthwebula kwe-SWIR. Izinzwa ze-InGaAs zingakwazi ukubona ububanzi obubanzi bamaza wamaza we-SWIR futhi zivame ukusetshenziswa ezinhlelweni ezihlukahlukene ezihlanganisa ukutholwa kwegesi nokuqapha indawo ezungezile.
● Ukuqhathanisa Nezinye Izinto
Nakuba i-InGaAs idume ngobubanzi bayo obubanzi nokuzwela, ezinye izinto ezifana ne-Mercury Cadmium Telluride (MCT) ne-Lead Sulfide (PbS) nazo ziyasetshenziswa, nakuba zingavamile. I-InGaAs inikezela ngezinzuzo ezimbalwa ngalezi zinsiza, okuhlanganisa ukusebenza kahle okungcono kanye namazinga aphansi omsindo, okuyenza ibe into ekhethwayo kubakhiqizi nabahlinzeki bekhamera abaningi be-SWIR.
Izinzuzo ze-SWIR Imaging

Ekwenziweni kwe-semiconductor, ukunemba kubaluleke kakhulu. Amakhamera e-SWIR asetshenziswa ngekhono lawo lokuveza amaphutha kuma-wafers namasekethe ahlanganisiwe angabonakali ngamasu ajwayelekile wokuthwebula izithombe. Leli khono likhulisa ukusebenza kanye nekhwalithi yezinqubo zokuhlola.
● Imifanekiso Yezokwelapha Nezolimo
Emfanekisweni wezokwelapha, amakhamera e-SWIR asetshenziselwa ukuxilongwa okungahlangani, anikeza imibono enemininingwane esiza ekuhlolweni kwezokwelapha. Kwezolimo, lawa makhamera angakwazi ukuqapha impilo yezitshalo ngokuthola okuqukethwe kwamanzi kanye nezimpawu zokucindezeleka ezitshalweni. Lolu lwazi luwusizo kakhulu ekuthuthukiseni ukuchelela kanye nokwenza ngcono isivuno sezitshalo.
Ukuthwebula kwe-SWIR ku-Low-Light Conditions
● Ukusetshenziswa Kokukhanya Kwasebusuku
Esinye sezici eziphawulekayo zamakhamera e-SWIR amandla awo okusebenza kahle ezimeni eziphansi-ezikhanyayo. Bangasebenzisa ukukhanya kwasebusuku, okuwukukhanya okuncane okukhishwa isibhakabhaka ebusuku, ukuze bakhiqize izithombe ezicacile. Leli khono libalulekile ezinhlelweni zokusebenza ezifana nokugadwa nokuphepha, lapho ukubonakala kuvame ukuba sengozini.
● Izinzuzo Zokuphepha Nokugada
Emkhakheni wezokuphepha nokugadwa, ikhono lamakhamera e-SWIR okubona ngenkungu, inkungu, ngisho nezinto ezifana nengilazi ziwenza abaluleke kakhulu. Banikezela ngamakhono wokucabanga imini nobusuku, banikeze izinga elilinganayo lokuphepha kungakhathaliseki isikhathi noma izimo zezulu. Lokhu kwethembeka kuyindawo ebalulekile yokuthengisa yanoma yimuphi umkhiqizi noma umhlinzeki wekhamera ye-SWIR.
Intuthuko Yezobuchwepheshe kumakhamera we-SWIR
● Ukuthuthukiswa Okusha Nokuqanjwa
Inkambu yezithombe ze-SWIR ithuthuka ngokuqhubekayo. Intuthuko yakamuva ihlanganisa ukuthuthukiswa kwezinzwa eziphezulu-ezichazayo namandla okucubungula ngokushesha. Ukuqanjwa okusha okufana ne-multi-spectral imaging, lapho i-SWIR ihlanganiswa namanye amabanga wamaza wamaza, nawo ayazuza. Le ntuthuko ithembisa ukwandisa izinhlelo zokusebenza futhi ithuthukise ukusebenza kahle kwamakhamera we-SWIR nangaphezulu.
● Amathrendi Nentuthuko Yesikhathi esizayo
Uma ubheka phambili, ikusasa lamakhamera e-SWIR libonakala lithembisa. Ngocwaningo oluqhubekayo nentuthuko, ukuthuthukiswa kobuchwepheshe bezinzwa, kanye nokuhlanganiswa kobuhlakani bokwenziwa ukuze kube nezixazululo ezihlakaniphile zokucabanga, amakhono amakhamera we-SWIR asethwe ukuze afinyelele ukuphakama okusha. Lezi ntuthuko zizowenza abe ngamathuluzi aguquguqukayo futhi asebenza ngempumelelo, ngaleyo ndlela andise isikhalo sabo kubahlinzeki bekhamera be-SWIR abadayiswayo kanye nabakhiqizi bamakhamera base-China SWIR ngokufanayo.
Isiphetho kanye Nolwazi Lokuxhumana
● Ukufingqa Izinzuzo
Amakhamera e-SWIR anikezela ngezinzuzo ezingenakuqhathaniswa ngokuya ngokulungiswa, ukuzwela, kanye nokuguquguquka. Zihamba phambili ezimweni eziphansi-zokukhanya futhi ziyakwazi ukubona ngezinto ezifiphele kuya ekukhanyeni okubonakalayo, okuzenza zibe wusizo kuzo zonke izimboni ezihlukahlukene. Njengoba intuthuko yezobuchwepheshe iqhubeka nokuthuthukisa amakhono abo, ikusasa lezithombe ze-SWIR libukeka likhanya ngokwedlulele.
