Te Tātari i ngā Hapa Pūnaha o te Photodetector

Te Tātari i ngā Hapa Pūnaha o te Photodetector

He Kupu Whakataki ki ngā Take Whakaawe i ngā Hapa Pūnaha i roto iPūoko Whakaahua

Ko ngā whakaaro motuhake mō te hapa pūnaha ko: 1. Te kōwhiringa wāhanga:ngā diode whakaahua, ngā whakakaha whakahaere, ngā ātete, ngā pūnga iahiko, ngā ADC, ngā ics tuku hiko, me ngā pūtake ngaohiko tohutoro. 2. Taiao mahi: Te awe o te pāmahana me te haumākū, me ētahi atu. 3. Te pono o te pūnaha: Te pumau o te pūnaha, te mahi EMC.

Tātari Hapa Pūnaha o ngā Pūoko Whakaahua

1. Whakaahua-ira: I roto i tete kimi hiko-whakaahuapūnaha, te awe o ngā photodiode ki ngā hapa o tepūnaha whakaahua-hikoe whakaatuhia ana i roto i ngā āhuatanga e whai ake nei:

(1) Te Tairongo (S)/ Te Taumira: Ko te ōwehenga o te pikinga tohu putanga (ngaohiko/au) △y ki te pikinga tāuru △x e hua ai te pikinga putanga △y. Arā, s=△y/△x. Ko te tairongo/taumira te āhuatanga matua mō te kōwhiringa pūoko. Ka kitea motuhaketia tēnei tawhā i roto i te hononga tika o ngā photodiode hei au pōuri, me te whakaaturanga motuhake o ngā photodetector hei mana ōrite haruru (NEP). Nō reira, ko te tātaritanga matua o te hapa pūnaha e hiahia ana kia teitei ake te tairongo (S)/taumira i te whakaritenga hapa tuturu kia tutuki ai ngā whakaritenga hapa o te pūnaha photoelectric katoa, nā te mea me whai whakaaro anō hoki ki te pānga hapa i puta mai i ngā āhuatanga kua whakahuatia i muri mai.

(2) Te Raina (δL): Ko te nui o te raina o te whanaungatanga tauanga i waenga i te putanga me te whakaurunga o te taputapu whakaahua. Ko te yfs te putanga tauine-katoa, ā, ko te △Lm te peka mōrahi o te raina. Ka kitea tēnei i roto i te raina me te kaha mārama kua taurite te raina o te taputapu whakaahua.

(3) Te Pūmautanga/Te Whakahoki Anō: He rerekētanga te putanga o te pūoko whakaahua mō te whakaurunga matapōkere kotahi, he hapa matapōkere tēnei. Ka whakaarohia te rerekētanga mōrahi o ngā whiu whakamua me ngā whiu whakamuri.

(4) Hysteresis: Ko te āhuatanga e kore ai e taupatupatu ngā ānau āhuatanga whakauru-putanga o tētahi pūoko whakaahua i a ia e haere whakamua ana, e haere whakamuri ana hoki.

(5) Te rerekētanga pāmahana: Ko te awe o ia huringa pāmahana 1℃ ki te huringa putanga o te taputapu whakaahua. Ko te rerekētanga o te rerekētanga pāmahana △Tm i puta mai i te rerekētanga pāmahana ka tatauhia mā te tatau i te rerekētanga pāmahana o te awhe pāmahana taiao mahi △T.

(6) Te nekeneke o te wā: Ko te āhuatanga e rerekē ai te putanga o te pūoko whakaahua i roto i te wā ina kore e rerekē te taurangi whakauru (ko te nuinga o ngā take he panoni i roto i tōna ake hanganga hanganga). Ka tatauhia te awe whānui o te pūoko whakaahua ki te pūnaha mā te tapeke whārite.

2. Ngā whakakaha whakahaere: Ngā Tawhā Matua e Pā Ana ki te Hapa Pūnaha Ngā Whakakaha Whakahaere Ngaohiko Taupatupatu Vos, te nekehanga pāmahana Vos, te iahiko taupatupatu tāuru Ios, te nekehanga pāmahana Ios, te iahiko taupatupatu tāuru Ib, te aukati tāuru, te kaha tāuru, te haruru (haruru ngaohiko tāuru, te haruru iahiko tāuru) Haruru wera whakanui hoahoa, te ōwehenga whakakorenga tuku hiko (PSRR), te ōwehenga whakakorenga aratau-noa (CMR), te whakanui whakatuwhera-porowhita (AoL), te hua whānui-whakanui (GBW), te tere hurihuri (SR), te wā whakatū, te whakapōturitanga harmonic katoa.

Ahakoa he rite te hiranga o ngā tawhā o ngā whakakaha whakahaere ki te hiranga o te pūnaha ki te kōwhiringa o ngā photodiode, nā te iti o te wāhi, kāore e whakamāramahia ngā whakamāramatanga me ngā whakaahuatanga tawhā motuhake i konei. I roto i te hoahoa tuturu o ngā photodetector, me aromatawai katoa te awe o ēnei tawhā ki ngā hapa pūnaha. Ahakoa kāore pea ngā tawhā katoa e pā nui ki ngā whakaritenga o tō kaupapa, i runga i ngā horopaki tono tuturu me ngā tono rerekē, ka rerekē ngā pānga o ngā tawhā o runga ake nei ki ngā hapa pūnaha.

He maha ngā tawhā mō ngā whakakaha whakahaere. Mō ngā momo tohu rerekē, ko ngā tawhā matua e puta ai ngā hapa pūnaha ka taea te arotahi ki ngā tohu DC me AC: Ngā tohu taurangi DC Te ngaohiko tauwehenga tāuru Vos, te nekehanga pāmahana Vos, te iahiko tauwehenga tāuru Ios, te iahiko tauwehenga tāuru Ib, te aukati tāuru, te haruru (haruru ngaohiko tāuru, te haruru iahiko tāuru, te haruru wera whakanui hoahoa), te ōwehenga whakakorenga tuku hiko (PSRR), te ōwehenga whakakorenga aratau-noa (CMRR). Tohu rerekētanga AC: Haunga ngā tawhā o runga ake nei, me whai whakaaro anō hoki ki ēnei: ​​te kaha tāuru, te whakanui i te koropiko tuwhera (AoL), te hua whānui-whakanui (GBW), te tere whakarere (SR), te wā whakatū, me te whakapōturitanga harmonic katoa.
