Qalabka ogaanshaha sawir-qaadista ee ROF InGaAs ee bixiya sawir-qaadista hal-foton oo bilaash ah oo shaqeeya

Sharaxaad Gaaban:

Badeecadani waa qalab yar oo sawir-qaade ah oo ku shaqeeya infrared-ka oo aan lahayn koronto. Qalabka asaasiga ah wuxuu qaataa InGaAs/lnP oo leh xuquuqda hantida garaadka ee madaxa-bannaan ee gudaha. Marka la barbar dhigo alaabada la midka ah, APD waxay leedahay tilmaameyaal farsamo oo horumarsan, isku hallayn iyo is-dhexgal, waxaana loo isticmaali karaa ogaanshaha iftiinka hooseeya ee aan isku mid ahayn sida liDAR iyo ogaanshaha cimriga iftiinka. Codsiyada waxay bixiyaan xalal kharash-ool ah.
Badeecadani waxay isticmaashaa jawaab celin taban APD si loo gaaro daminta barafka degdega ah iyo buuqa elektaroonigga ah oo hooseeya, hufnaanta ogaanshaha sare iyo tirada mugdiga oo hooseysa iyadoo la hagaajinayo elektaroonigga iyo naqshadeynta kuleylka. Kuwaas waxaa ka mid ah, hufnaanta ogaanshaha ugu badan ee 1550nm photon keli ah waa > 35%; Waqtigan xaadirka ah, gariirka waqtiga wuxuu noqon karaa mid hooseeya sida 80ps; Hufnaanta ogaanshaha. 15%, tirada ugu yar ee mugdiga ah waa 500 CPS, garaaca ugu yarna waa 1% @ waqtiga dhintay 5 um; Heerka tirinta dheregta ilaa 4MCps@ waqtiga dhintay 250ns. Intaa waxaa dheer, xaaladaha gaarka ah ee codsiyada, taageerada eexda, heerka baaritaanka, waqtiga dhintay iyo xuduudaha kale ee shaqada habaynta isticmaalaha si loo xoojiyo hufnaanta ogaanshaha, heerka tirada dheregta iyo tilmaamayaasha kale ee gaarka ah; Shaqada beddelka dijitaalka ah ee waqtiga taageerada (TDC) waa la go'aamin karaa. Si loo helo xogta tirinta waqtiga, taageer orodka bilaashka ah ama albaabka kicinta dibadda. Laba qaab oo hawlgal ah ayaa la heli karaa.
