Ngā Āhuatanga

Kauwhata Taipitopito

Kupu Whakataki mō te arotahi Si

Nā te pumau o ōna āhuatanga tuku hihi infrared me ōna āhuatanga ā-tinana tino pai, kua whānuitia te whakamahi i te silicon hei rauemi mō ngā hoahoa whatu waenga-infrared. Ina honoa ki tētahi paninga IR AR i hangaia kia āta, ka whakaratohia e ngā karāhe silicon he otinga utu-pai me te mahi-teitei mō ngā pūnaha whakaahua me te pūoko hihi infrared hou.

Ngā Āhuatanga Rauemi me ngā Painga Mahi Si Arotahi

He rite tonu te tukunga o te hihi infrared o te silicon i roto i te1.2–8 µmte whānuitanga o ngā roangaru, ā, he tino pai mō3–5 μm (MWIR)ngā tono. Mā ōna āhuatanga ā-tinana ka taea e ngā karāhe silicon te pupuri i te pumau o te whatu me te ā-mīhini ahakoa i raro i ngā āhuatanga mahi uaua.

Ko ngā painga matua o ngā rauemi ko:

Te kawe wera teitei mō te tohatoha wera pai
He kaha miihini kaha me te ātete ki te ru wera
He iti ake te taumaha ki te germanium, e āhei ai te hoahoa pūnaha kiato
He pai te pumau o te taiao me te matū
Hototahi ki ngā tukanga hanga whatu tino tika

Nā ēnei āhuatanga ka waiho ngā karāhe silicon hei kōwhiringa pai rawa atu mō ngā pūnaha infrared me mahi pono mō ngā wā roa, i roto rānei i ngā taiao pāmahana e rerekē haere ana.

Hoahoa Paninga Ārai-Whakaata o te Pōkākā Si

Nā te mea he teitei te taupū whakaata o te silicon, ka taea e ngā mata kāore i pania te whakaputa i ngā ngaronga whakaata nui. Hei whakatika i tēnei,ngā paninga ārai-whakaata infraredka whakamahia ki ngā mata arotahi hei whakapai ake i te whai huatanga o te tirohanga.

Kua hangaia te paninga IR AR ki te:

Whakaitihia ngā whakaata Fresnel i ngā atanga silicon-hau
Whakanuia te tuku whai hua puta noa i te roopu infrared ūnga
Whakapai ake i te māramatanga o te ahua, te rerekētanga, me te aro ki te kimi
Āraihia ngā whakaata kotiti ke i roto i ngā huihuinga whatu

Ka taea te whakapai ake i ngā hoahoa paninga mō ngā awhe roangaru motuhake pēnei i te3–5 μm (MWIR) or 8–12 μm (LWIR), tae atu ki ngā roopu infrared ritenga kua tautuhia e ngā whakaritenga pūnaha.

Hoahoa Whatu me te Hanga Ngāwari o te arotahi Si

Kei te wātea ngā karāhe whatu silicon infrared me te paninga IR AR i roto i te whānuitanga o ngā whirihoranga whatu hei tautoko i ngā hoahoa pūnaha kanorau:

Ngā karaihe papa-pūpū, papa-kōpiko, rua-pūpū, me rua-kōpiko
Ngā āhua porowhita me ngā āhua porowhita ritenga
Paninga ārai-whakaata IR taha-kotahi, taha-rua rānei
Te oro tika mō te āhua mata me te taratara e whakahaeretia ana

Ka āta tirotirohia ngā tukanga hangahanga kia rite tonu ai te roa o te arotahi, te tika o te mata, me te mahi paninga. Ka tautokona ngā hoahoa ritenga mō te diameter, te matotoru, te piko, te manawanui, me ngā whakaritenga paninga.

Ngā Wāhi Whakamahinga

Ko ngā karaihe silicon me te paninga ārai-whakaata IR e whakamahia whānuitia ana i roto i:

Ngā pūnaha whakaahua wera me te tirohanga pūwhero
Ngā taputapu kimi me te ine pāmahana infrared
Ngā taputapu aroturuki me te tirotiro ahumahi
Te tirotiro ira-whero me ngā taputapu taiwhanga
Ngā pūnaha tuku taiaho whero me te tuku whatu

Nā te taurite o te mahi me te pakari e pai ai mō ngā tono pūwero-whero arumoni me ngā tono ahumahi.
