Izici ezinomthelela zephutha lesistimu yeama-photodetectors
Kunamapharamitha amaningi ahlobene nephutha lesistimu lama-photodetectors, futhi ukucatshangelwa kwangempela kuyehluka ngokuya ngezinhlelo zokusebenza zephrojekthi ezahlukahlukene. Ngakho-ke, i-JIMU Optoelectronic Research Assistant yathuthukiswa ukuze isize abacwaningi be-optoelectronic baxazulule ngokushesha iphutha lesistimu lama-photodetectors futhi bakhe ngokushesha amasistimu e-optoelectronic, ngaleyo ndlela afinyeze umjikelezo wephrojekthi futhi agweme ukuqala kusukela ekuqaleni ukuze kuhlaziywe nokuklama.
3. Ukumelana
(1) Inani lokumelana: Ukukhethwa kwamanani afanelekile okumelana kuhilelekile kusici sokukhulisa ama-amplifiers okusebenza, ukumelana nokulinganisa, ukuhlunga kwe-RC, njll. Inani lokumelana akufanele libe likhulu kakhulu, njengoba inani lokumelana likhulu, isignali iba buthakathaka, ukusebenza kabi kokulwa nokuphazamiseka, kanye nomsindo omkhulu we-Gaussian omhlophe. Akufanele futhi kube kuncane kakhulu, njengoba ukusetshenziswa kwamandla kuzokwenyuka futhi kungase kukhiqize ukushisa futhi kuthinte isikhathi sokuphila.
(2) Amandla: Qinisekisa ukuthi i-P=I^2*R aweqi amandla ayo alinganiselwe, futhi ukuze uvimbele isiphikisayo ekushiseni ngokweqile, akufanele sidlule ingxenye yamandla aso alinganiselwe.
(3) Ukunemba: Kunomthelela omncane ekunembeni kwesistimu yokulinganisa kabusha.
(4) Ukukhukhuleka kwezinga lokushisa: Ukukhukhuleka kwezinga lokushisa kwezinto eziphikisayo kuyisici esibalulekile sokucatshangelwa ekubalweni kwamaphutha esistimu.
4. I-Capacitor
(1) Inani lamandla: Kumasekhethi ahlobene nokuhlunga kwe-RC, izikhathi ezingaguquki, njll., inani lomthamo lidinga ukubalwa ngokunembile. Idizayini yesistimu ayikwazi ukuziba isikhathi esingaguquki sokusungulwa kwesignali ukuze nje kuhlungwe amaza okuphazamisa. Kudingeka ukucabangela izidingo zakho kokubili isizinda sefrikhwensi kanye nesizinda sesikhathi ngesikhathi esisodwa ukuze kuhlangatshezwane nezidingo zokuhlunga kanye nesikhathi sokusungulwa kwesignali.
(2) Ukunemba: Uma uhlelo lwakho lokusebenza luhlobene namasiginali wemvamisa ephezulu noma ludinga umkhawulokudonsa wokuhlunga ophezulu, udinga ukukhetha ama-capacitor anembayo ephezulu. Ngokuvamile, izidingo zokunemba zama-capacitor azibucayi kakhulu.
(3) Ukwehla kwezinga lokushisa.
(4) Ukumelana nengcindezi: Kumelwe ihlangabezane nemibandela yokuklama eyehlisayo, ngesilinganiso esijwayelekile esingama-20% somkhawulo wohlelo lokusebenza.
4. Izinga lokushisa lokusebenza
(1) Nquma ububanzi bezinga lokushisa elisebenzayo ngokusekelwe ezidingweni zomkhiqizo we-photodetector. Isibonelo: Ibanga lokushisa elisebenzayo le-IVD ethile yezokwelaphaumkhiqizo we-photodetectorku-10 kuye ku-30 ℃. Le mfuneko yezinga lokushisa ibaluleke kakhulu ngoba imingcele ehlobene nokukhukhuleka kwezinga lokushisa kwezingxenye ezifana nezikhulisamandla zokusebenza, izihlungi, nama-ADC okukhulunywe ngazo ekuqaleni zonke zihlobene eduze nezimfuneko zokushisa zokusebenza komkhiqizo. Uma kucatshangelwa uhla lomehluko wamazinga okushisa kanye nomthelela womehluko wokushisa ngaphansi kwezimo zangempela zokusetshenziswa kwemvelo, kuyaqinisekiswa ukuthi umthelela ophelele wezinguquko kupharamitha ngayinye ngaphakathi kwaleli banga awedluli imfuneko yokugcinaisistimu ye-photoelectriciphutha.
(2) Thola ukuthi zikhona yini izingxenye ezizwelayo ukuswakama kanye nokuthi izidingo zendawo yomswakama ziyahlangatshezwa yini: Thola ububanzi bezinguquko zomswakama endaweni yokusebenza kanye nemingcele yemishini ezwela ukuswakama ethinta imiphumela.
5. Ukuzinza nokuthembeka kwesistimu kuhambisana nokwakheka kokuzinza kwe-photodetector. Imfuneko yokwenza izibalo zamaphutha esistimu ukuthi uhlelo luzinzile futhi akufanele luthintwa imvelo ehlobene ne-EMC; ngaphandle kwalokho, zonke izibalo azisho lutho. Ngenxa yokulinganiselwa kwesikhala, lesi sahluko ngeke siqhubeke sichaza kabanzi. Lezi zici ezimbili ezilandelayo kufanele zicatshangelwe ngokuyinhloko. Ekwakhiweni kwesekethe, ukucatshangelwa okuqinile kokuvikela kanye nezinyathelo zokugwema kufanele kuthathwe ku-EMI kanye ne-EMS. B. I-casing, ukuvikela izintambo zokuxhuma, izindlela zokumisa phansi, njll. nakho kudingeka kuhlaziywe futhi kuqinisekiswe.
