Te whakapōturi i ngā tikanga tuku ihoKaiwhakarerekē LiNbO3
Nō nā tata nei, kua whakaputahia e tētahi rōpū rangahau i Haina tētahi mana pateni hou mō te hangarau raka auau taiaho mā te whakamahi i te LiNbO3 modulator. Ko te uho o te mana pateni he pūnaha raka auau taiaho PDH (Pound Driver Hall) hou e huri ana i ngā tikanga tuku iho.
1. Ngā āhuatanga mamae o te hangarau tuku iho:
Ko ngā pūnaha raka auau PDH tuku iho e whakamahi ana i te lithium niobate (LiNbO3)kaiwhakarerekē hiko-whatuhei whakaputa i ngā taha taha whatu e hiahiatia ana. E toru ngā raruraru matua o tēnei huarahi: te utu nui me te hanganga uaua (e hiahiatia ana he ara iahiko taraiwa RF uaua), te aro ki te taiao (ka taea e ngā huringa pāmahana me te ahotea te arahi ngāwari ki te mahi kore pumau), me ngā pānga whakarerekētanga kaha toenga (RAM), ka taea te whakararu i te tohu raka me te pā kino ki te pumau roa o te pūnaha.
2. Ngā otinga auaha:
Kua whakarērea rawatia e ngā tīma rangahau Hainamana te whakarerekētanga hiko-whatu tuku iho. Ko te auahatanga matua kei roto i te hoahoa mahi tahi o te "whakakaha whatu semiconductor (whakakaha SOA) me te whakawhiti auau acousto-whatu rua-awa (whakakaha AOM)". Ko te kaupapa motuhake ko: i muri i te wehewehe i te hihi taiaho purapura, e ruaKaiwhakarerekētanga AOMe whakamahia ana mō te nekehanga auau tika, kātahi ka werohia ēnei hihi mārama e rua ki roto i te whakakaha SOA i roto i te āhua kukū whiwhi. Whakaputahia pai te tohu maha-taha e hiahiatia ana mō te raka auau PDH mā te whakamahi i ngā pānga kore-raina pēnei i te whakaranu ngaru whā (FWM) i rotoWhakakaha SOA.
3. Ngā painga mahi i kawea mai e:
Te pumau mutunga kore: Kua whakauruhia ngā taputapu SOA (pēnei i te takai pūrerehua) ki te whakahaere pāmahana, ā, kāore e pāngia e ngā raruraru taiao, ka whakakorea pai ngā pānga RAM mai i tētahi tikanga ā-tinana, ā, ka tutuki ai te raka roa tino tika (pai ake i te 5 × 10 ⁻¹¹/rā).
Te ōwehenga tohu-ki-haruru teitei: Mā te whakahaere motuhake i te nekehanga auau o te pūwhakarerekētanga AOM takirua, ka taea te whakatutuki i te taurite tika i waenga i te auau taha me te awhe hiato kore utu (FSR) o te kōhao tohutoro, ā, ka tino whakapai ake i te ōwehenga tohu-ki-haruru o te tohu hapa.
Te whakaiti i te utu me te whakaitiiti: Ka whakakorehia e te whakakaha SOA ngā whakarerekētanga hiko-whatu utu nui me ngā ara iahiko uaua, e hiahia ana kia ngawari noa te taraiwa iahiko. Mā tēnei ka nui ake te kiato me te whai hua o te pūnaha, ka pai ake te whakaiti me te whai hua o te taputapu.
4. Ngā tūmanakohanga tono me te hiahia o te mākete:
Ka tutuki tika i tēnei hangarau te hiahia nui mō ngā pūtake taiaho tino pumau i roto i te whanaketanga o te hangarau matūriki, ā, he whānui ngā tono, tae atu ki:
He karaka rama kei runga i te wāhi me te waka (me ātete ki ngā wiri nui).
Ine taumaha kuantum me te ine ā-ngota matao (e whakamahia ana mō te tūhuratanga whenua me te whakatere i raro i te wai).
Te pūoko muka whatu matatau me te LiDAR.
I te mākete o nāianei, inā koa i roto i ngā mara o te rangahau pūtaiao, te ahumahi hōia, me te rererangi arumoni, kei te piki haere te hiahia mō ngā waeine taiaho auau pumau ka taea te whakahaere motuhake, he iti te utu, he tino pumau hoki mai i ngā umanga. E hopu tika ana tēnei hangarau patent i tēnei ia o te mākete.
