Iterambere riherutse mu mitekerereze miremire Avalanche Amafoto

Iterambere rya vuba muriubushishozi bwo hejuru pulanche Fopitoir

Ubushyuhe bwicyumba kinini 1550 nmAvalanche Photodiode detector

Mu itsinda ryegereye (swir), sennutivite yo hejuru yihuta yihuta ya avalanche ikoreshwa cyane mubitumanaho bya optoelectronic na lidar Porogaramu. Ariko, ubu iri hafi-infral-infralanche Photodiode (Apd) yiganjemo indium Gallium Arsenic Avonche Urusaku rwinshi Inalas), bikaviramo kugabanuka kwinshi mubikoresho. Mu myaka yashize, abashakashatsi benshi barimo gushakisha cyane ibikoresho bishya bya semiconductor bihujwe na Ingaas na Ing optoelectronic gahunda kandi bafite ingaruka nkeya zidasanzwe Ioniation Ibikoresho bisa na silicon ya silicon.

Udushya 1550 Nm Avalanche Photodiode Statector ifasha iterambere rya sisitemu ya Lidar

Itsinda ry'abashakashatsi bo mu Bwongereza ndetse na Amerika bafite ubwambere gutsinda neza ultra-sensutivite nshya 1550 nm apd Photopdetector (Avalanche Photodetetector), ihuriro ryiyemeza kunoza cyane imikorere ya sisitemu ya Lidar nandi porogaramu ya Optoelectronic.

Ibikoresho bishya bitanga ibyiza byingenzi

Ikintu cyaranze ubu bushakashatsi ni ugukoresha udushya kubikoresho. Abashakashatsi bahisemo Gaassib nko kwinjiza igice na algaassb nk'ikibaya. Iki gishushanyo gitandukanye na Ingaas / INP kandi kizana ibyiza byinshi:

1.Goassb itsb urwego: Gaassb ifite ibikorwa bisa na Ingaas, hanyuma inzibacyuho ikwiranye na Algaassb (Igice Cyiza) biroroshye kandi byonoza imikorere yihuta kandi yinjira neza.

2.Algaassb mubyiciro byinshi: Igice cya Algaasb Clayer kiruta urwego gakondo na inalas mumirongo myinshi mubikorwa. Iragaragarira cyane cyane mu nyungu ndende ku bushyuhe bw'icyumba, umurongo muremure kandi ultra-urusaku rurenze.

Hamwe nibipimo byiza byimikorere

GishyaAPD Photodetetector.

1. Ultra-Inyungu Zimbere: Inyungu nini ya Ultra-Hejuru 278 yagezweho mubushyuhe bwicyumba, kandi iherutse kuba Dr. Jin Xiao yazamuye imiterere yo guhitamo no gutunganya, kandi inyungu nini yariyongereye kuri m = 1212.

2. Urusaku ruto cyane: kwerekana urusaku rurenze (F <3, kunguka M = 70; f <4, inyungu m = 100).

3. Gukora neza: Muburyo ntarengwa, imikorere ya Quanim ni hejuru ya 5935.3%. Ubushyuhe bukomeye buhamye: Gusenyuka kwiyumvisha ubushyuhe buke bugera kuri 11.83 MV / K.

Ibyifuzo byinshi

Iyi APD Nshya ifite akamaro ka sisitemu ya Lidar na Porogaramu ya Photon:

1. Kunoza ibimenyetso-kuri-urusaku: Inyungu ndende hamwe nurusaku rwinshi kunoza uburyo bwo kunoza ibimenyetso-ku rusaku, bukaba bukomeye kuri porogaramu muri Fhoto-mato.

2. Guhuza cyane: Photodetetector nshya ya APD (Avalanche Photoppetector) yagenewe guhuza phophide iriho (inp) ibishushanyo mbonera, kugirango bihuze ibitagenda neza hamwe na sisitemu yo gutumanaho.

3. Gukora neza: Irashobora gukora neza mubushyuhe bwicyumba nta buryo bwo gukonjesha ibintu bigoye, byorohereza koherezwa muburyo butandukanye.

Iterambere ryiyi 1550 NMP Photodetector (Avalanche Photodetector) yerekana urusaku rwinshi rwa APD (Avalanche Photopdetector) Ibishushanyo. Biteganijwe ko iyi nshyi yo kuzamura ubushobozi bwa sisitemu ya lidar, cyane cyane muri sisitemu ya lidar idafite amakimbirane, ndetse no gutumanaho.
