Ukubhekana kwe-Emitters nokuhlelwa kwezimilo zocingo

Ukuziqonda I-imeyitha Time Constant ne-Effect Yalo Kusukela Sinyathelo

Izinkinga Zokugcina Kwe-Thermal Inertia Kwisikhathi Sokuphinda Kwama-IR Emitter

Ukuphakanyiswa kwezindawo zokukhipha isikhathi sokugcina kwezitha kuyisibonelo sokuthi ukuthi izinto zikwenzani ngokuphelele ukuthi zizokhanya, okusho ukuthi azikwazi ukuziphatha ngokushesha kuma-pulse elektriki. Umkhondo wokuphakanyiswa akuzange ukuthi ukuguqula isikhathi kusenza ngokuphelele, futhi kukhona kahle lokhu kuhlanganisa phakathi kokuthi iphuleli yekheshini yasemthwakathini kanye nokuthi sibona ukukhanya okuphelele. Sizimisa lokhu ngokusebenzisa loo thime konstant (okubhekwa njengokuqondwa njengoku-tau), futhi kuzoba kusela kuma-milionthi kuya kuma-thousandthi yesikhathi ngokubonakalayo kokuthi indawo iyabakwa kanjani. Uma ama-pulse asithumayo ayisinye kakhulu kune-thime konstant, indawo ayikwazi ukuphakanyiswa kakhulu ukuze isebenze ngokuphelele, futhi ubukhulu bekho bokushaya buyaphela kusukela emva kwezinkambo ezimbili. Hlola umzekelo apho isikhathi sokugcina siyisikhathi sekheshini esingama-10 milliseconds. Ukuze sifike kuma-brightness okuphelele, lezi zi-pulse kufanele zilunge kusukela emva kwezinkambo ezimbili ze-15 milliseconds. Kwaye kuyakhiwa inkululeko yokuchitha kakhulu, okuyisibonelo sokuthi ukuthi isikhathi sokugcina sikwazi ukubeka isikhathi sokukhanya ngokushesha, okuyisibonelo sokuthi isikhathi sokugcina sikwazi ukubeka isikhathi sokukhanya ngokushesha. Lokhu kuyisibonelo sokuthi isikhathi sokugcina sikwazi ukubeka isikhathi sokukhanya ngokushesha, okuyisibonelo sokuthi isikhathi sokugcina sikwazi ukubeka isikhathi sokukhanya ngokushesha. Lokhu kuyisibonelo sokuthi isikhathi sokugcina sikwazi ukubeka isikhathi sokukhanya ngokushesha, okuyisibonelo sokuthi isikhathi sokugcina sikwazi ukubeka isikhathi sokukhanya ngokushesha. Lokhu kuyisibonelo sokuthi isikhathi sokugcina sikwazi ukubeka isikhathi sokukhanya ngokushesha, okuyisibonelo sokuthi isikhathi sokugcina sikwazi ukubeka isikhathi sokukhanya ngokushesha.

Ukwenza ngcono imvamisa yokumodula: Ukulinganisela ububanzi be-bandwidth nokusebenza kahle kokukhanya

Ukuthola imvamisa yokumodula efanele kusho ukuthola indawo enhle phakathi kokuthi ingakanani idatha engadluliselwa nokuthi amandla asetshenziswa kahle kangakanani. Lapho amaza enyuka, amazinga wedatha ayaqabula, kodwa umjikelezo ngamunye wokushisa uyafushane, okwenza izinto zibe zimbi nakakhulu ngokombono wokushisa. Ukuphinda kabili imvamisa? Lindela ukwehla okungamaphesenti angu-30 kuya kwangu-40 embonini yokukhanya. Kukhona uphahla lwezwe langempela lapha futhi, olubalwa ngokuthi f_max ilingana no-1 elihlukaniswe no-2 pi x tau. Ngokwesibonelo, cabanga ngomshini wokukhipha umsakazo onesikhathi sokuphendula esingamasekhondi angu-5. Lezi zivame ukusebenza kahle cishe ngama-32 hertz lapho zigcina khona ukusebenza kahle okungaphezulu kwama-80% ngaphandle kokulahlekelwa yi-bandwidth ebalulekile. Futhi ungakhohlwa nangemijikelezo yomsebenzi. Abantu abaningi bathola ukuthi ukugcina isikhathi phakathi kuka-25% no-40% kunikeza imiphumela emihle kakhulu ekusetshenzisweni kwezinzwa. Lolu hlu lusiza ukukhulisa izinga lesignali kuyilapho luvimbela lezo zinkinga ezimbi zokushisa ezingalimaza izingxenye ngokuhamba kwesikhathi.

Ukuhambisana Kwemibhalo Yokuqonda Phakathi Kwezindlela Zokuhambisa Kwemithombo Nokuthi Izingxenye Zokuthwala Kwengxenye Ekhethweyo

Ukulinganisa Ukungahambisani Kwemibhalo Ngokusebenzisa Imibhalo Yokuqonda Yomkhombisi Wokugcina Nokuthi Kuphakade Kwezindlela Zokuhambisa

Ukuthola iziphumo ezihlakanipile zengxenye zokuthwala kubhekise kakhulu ekuxhumeni kwemithombo yamandla yesikhathi esihlukene nesikhathi sokuthwala kwengxenye eyodwa. Umkhombisi wokugcina, okuyizindlela zokuhambisa, ubonisa indlela eyinkulu yokuhambisa. Ukuthi kuphakade kwezindlela zokuhambisa, okuyinto ebalulekile ukuthi isibalo sesikhathi sokuhambisa siphakade kangakanani. Uma umkhombisi wokugcina ushona ngokuphakade kwezindlela zokuhambisa ngokuphakade kwezindlela zokuthwala kwe-methane emva kwe-2.3 micrometers, ukuthwala kufika kwe-12 percent ngokusho kwabahloko abaphephile kusasa ngo-2023. Uma ukuthi kuphakade kwezindlela zokuhambisa kufika kwe-150 nanometers, kukhona ingxenye enkulu yokuvula kwamazwi amaningi. Amanzi asekhaya ayakwazi ukwenza ubudlelwane obukhulu kule mikhombiso. Ngakho ke izinhlangano zonke zingadinga amafiltela amasha ukubeka amazwi amaningi futhi ukuzinikela kuphela kwezinxenye zokuthwala ozothanda ukuzithola.

Izinhlangano Zokuhambisa Ngokujwayelekile Ngaphansi Kwesikhathi Esisheshayo Nokuhambisa Ngokujwayelekile Ngaphansi Kwesikhathi Esisheshayo: Izinqumo Zokuthwala Kwengxenye Zokuthwala

Amakhombe emva kwezinye izinxenye eziphakeme ayikhiqiza imizuzu yezinye izinxenye zezindawo zokuhluka kwe-IR kodwa abonisa ukuthi kunezinkundla ezingama-18% eziningi zokuthola okungafanele kumazulu apho kubonakala ukuthi kunezindawo zokuthola izilwane zomfula ngokufanana. Amakhombe emva kwezinye izinxenye eziphakeme abonisa ukuthola okuphelele kwegasilayi yokuqondwa ngama-97% futhi—lapho abizwa ngezinhlobo zokuphatha ezitholakala kusukela emazulwini—bazihlukanisa ukuthola okungafanele ngama-40% kulokho okwenziwa ngamakhombe amaningi, njengoba kubonakala kudatha yezinhlobo zokuthola kwezindawo zokusebenza ka-2024.

Imibuzo Evame Ukubuzwa

Isilimi sokuxhumana sithi ngani futhi kuyini okubalulekile kubamkhombe?

Isilimi sokuxhumana, esibhekiswe ngokuthi ‘tau’, sibonisa ukuthi kunezinkinga phakathi kokuthi kuthatheleka ubunzima kubamkhombe nokufika kwezindawo zokuthola okuphelele. Kubalulekile ngoba kuthinta ukuthi kuthatheleka kanjani ubamkhombe ukuthola izinguquko zokuthola, okuthinta ukuthi kuthatheleka kanjani isikhundla sokuthola nokusebenza kahle.

Ukuthi ukuthintana kwe-frekhwensi kuthinta kanjani ubukhulu bekho emitholeni?

Ukuthintana kwe-frekhwensi kudinga ukubalansha phakathi kwezinto ezihlanganisiweyo zokuthumela nokuphelele kwemisebenzi yomthelela. Ukuthintana okuphezulu kuhleza amathuba okuthumela, kodwa kunciphisa ukuthumela kwezilayithi ngokuphezulu, okuthinta ubukhulu bekho emitholeni. Ukuvumela kwe-frekhwensi kusiza ekubaleni ubukhulu ngaphandle kokungafiki kuphela kwe-bandwidth.

Kungani ukubaluleka kwe-spectral alignment kuzisikhuba zokufunda izigas?

Ukubaluleka kwe-spectral alignment kusiza ukuthi ukuthumela kwe-infrared kubalane nezibandlwanu zokuthinteka kwezisigas. Ukubalane okuhle kusiza ekufundeni izisigas ngokuhle futhi kunciphisa ukuthinteka kwezinye izinto njengezivuli zamehlo.

Ziziphi izindlela zokuthembeka noma zokungathembeki kwezimitholeni zokuthumela kwezibande ezingaphezu kwezibande ezingamnye?

Izimitholeni zokuthumela kwezibande ezingaphezu kwezibande ezingamnye zingafunda izisigas eziningi, kodwa ziyakhula kwezithinteka zokuthintana kwezibande. Izimitholeni zokuthumela kwezibande ezingamnye zinokuthembeka kakhulu kwezisigas ozifuna futhi zinokubalwa ngokuhle, kodwa zidinga ukubalwa okuhle kwezibande zokuthumela.
