Hordhac, Photon tirinta noocaPhotoDetoChector-ka Linear Avalankaaga
Tixraaca tikniyoolajiyadda ayaa si buuxda u soo kordhin kara sectal-ka sawirka si looga gudbo dhawaqa dib-u-eegida aaladda elektiroonigga ah, oo ay ku qoran tahay tirada sawir qaadista qalabka korantada, oo xisaabiso macluumaadka bartilmaameedka la cabiray iyadoo loo eegayo mitirka sawirka. Si loo hubiyo in la ogaado iftiinka daciifka ah, noocyo badan oo kala duwan oo leh awood muujinaya choton ogaanshaha Awoodda ogaanshaha ee sawirka ayaa lagu bartay dalal kala duwan. Plane Photanche Photodiode Modiodide (PhotoDetoCher apd) waa aalad u adeegsada saameynta sawirka gudaha ah ee soo ifbaxa calaamadaha iftiinka. Marka la barbar dhigo aaladaha faaruqa ah, aaladaha adag-gobolka waxay leeyihiin faa iidooyin muuqda oo xawaareynta, tirinta mugdiga, isticmaalka awooda, iwm.
Aaladda apd ee aaladdaMIDEE (GM) iyo Habka toosan (LM) Laba nooc oo shaqo, Photon hadda ah tirinta tikniyoolajiyadda sawirka ayaa inta badan adeegsata Gisd Model aaladda APD. Aaladda 'Gisd' ee APD Aaladaha APD waxay leeyihiin dareen xasaasi ah heerka sawir-gacmeedka iyo xawaaraha jawaabta sare ee tobanka nanoseconds si loo helo sax ahaanta waqtiga sare. Si kastaba ha noqotee, Geiger Mode APD waxay leedahay dhibaatooyin qaar ka mid ah qalabka wax soo saareyaasha, hufnaanta ogaanshaha, isgoysyada indhaha ee weyn iyo qaraarka hoose ee indhaha, sidaa darteed way adagtahay in lagu hagaajiyo heerka ogaanshaha sare iyo heerka muuqaalka muuqda ee been abuurka ah. Tilmaanta photon ee ku saleysan aaladaha 'HGCDTE' ee 'HGCDTE-ka' ee 'HGCDTE' ee 'HGCDTE APS' ayaa ku shaqeeya hab toosan, oo aan lahayn pulsel-ka yar oo laxiriira, oo aan si madaxbanaan u noqon karin si sahlan oo loogu talagalay ogaanshaha hufnaanta iyo heerka tirinta beenta ah. Waxay u fureysaa arji cusub oo arji ah timaha tirinta sawir qaadista, waa jiho muhiim ah oo horumarineed oo ah tigidhada tirinta Photon, oo leh rajo ballaaran oo ah kormeerka xiddigta, isgaarsiinta bannaan ee bilaashka ah, sawirka firfircoon, raadraaca.
Mabda 'Photon tirinta aaladaha HGCDTE apd
Aaladda APD-ga APD ee ku saleysan agabyada HGCDTE waxay dabooli karaan noocyo badan oo weedho ah, iyo isku-darka ionizations ee elektrons iyo godadku aad ayey u kala duwan yihiin (eeg sawirka 1 (a)). Waxay soo bandhigaan hal qaab isku-dhafan oo sidaha sidaha isku-dhafka ah ee ka dhex jira murqaha goynta ee 1.3 ~ 11 μm. Ma jiraan wax buuq ah oo xad dhaaf ah (marka la barbar dhigo qaylada xad-dhaafka ah ee FSI ~PhotoDetoChectoryaha.
Sawir 1 (a) Xiriirka ka dhexeeya saamiga wada-tashiga ioni-ga ee saameynta ee ah ee Mermium Cabsium Trifurke Qalabka iyo qeybaha x ee CD; (b) isbarbardhiga qodobka xad-dhaafka ah ee FAGE FAGRES APD oo leh nidaamyo kala duwan
Tixraacyada tikniyoolajiyadda waa tikniyoolajiyad cusub oo si isdaba joog ah uga soo bixin karta calaamadaha indhaha ee buuqa kuleylka iyadoo la xallinayo sawir-qaade sawirka aheegidka dib markii aad heshid hal sawir. Maaddaama calaamadaha iftiinka-hoose uu aad u kala firdhiyo waqtiga lagu jiro waqtiga, wax soo saarka calaamada korantada ee uu soo saaray sidoo kale waa wax dabiici ah oo waafaqsan. Marka loo eego astaamaha noocan ah ee iftiinka daciifka ah, saqafka garaaca wadnaha, takoorka garaaca wadnaha iyo farsamooyinka tirinta dhijitaalka ah ayaa badanaa loo isticmaalaa in lagu ogaado iftiin aad u daciif ah. Tixraaca tikniyoolajiyadda casriga ah waxay leedahay faa iidooyin badan, sida saamiga sawaxanka sare, sida saxda ah ee cabirrada sareeya, xasilloonida waqtiga wanaagsan, oo ay wax soo saarka taban tahay, oo ay ka soo baxaan takoorka schols-ka-dhijitaalka iyo socodsiinta, kaas oo aan ka soo bixin hababka kale ee ogaanshaha. Waqtigan xaadirka ah, nidaamka tirinta Photon ayaa si weyn loogu adeegsaday garoonka cabirrada warshadaha iyo soo-saarista iftiinka, sida sawir-qaadista aan tooska ahayn, iwm, kuwaas oo la xiriira soo-saarista iyo ogaanshaha calaamadaha iftiinka daciifka ah. The Mercury Cadtium Photodetetort ma leh dhagaxan xad dhaaf ah, iyadoo saamiyada garaaca garaaca ah ee la xidhiidha 'Geige Puble Avalanche', oo aad u muhiim ah oo ah jihada loo yaqaan 'photon' ee timaha tirinta sawir qaadista mustaqbalka.
