3. Ngā painga matua
Ko te uho o te awhe kitea ko te tawhiti rawa atu e taea ai e ngā photon e tukuna ana e te laser te wikitoria i te whakaiti i te āhuarangi me te ngaronga whakaata ūnga, ā, ka hopukina tonutia e te pito whiwhi hei tohu whai hua. Ko ngā tohu e whai ake nei o te laser pūtake kanapa 1.5 μm muka laser e tino whakahaere ana i tēnei tukanga:
① Mana teitei (kW): paerewa 3kW@3ns &100kHz； Ko te hua whakapai ake 8kW@3ns &100kHz te "kaha matua" o te awhe kimi, e tohu ana i te kaha tere e tukuna ana e te laser i roto i te kotahi pāorooro, ā, koinei te mea matua e whakatau ana i te kaha o ngā tohu tawhiti. I roto i te kimi i te drone, me haere ngā photon i ngā rau, i ngā mano mita rānei i roto i te āhuarangi, ka taea te whakaiti i te kaha nā te marara o Rayleigh me te mimiti hau (ahakoa kei roto te roopu 1.5 μm i te "matapihi āhuarangi", kei te noho tonu te whakaiti i te kaha). I taua wā anō, ko te whakaata o te mata ūnga (pēnei i ngā rerekētanga o ngā tipu, ngā konganuku, me ngā toka) ka arahi hoki ki te ngaronga o te tohu. Ina whakanuia te mana tihi, ahakoa te whakaiti i te tawhiti me te ngaronga o te whakaata, ka taea tonu e te maha o ngā photon e tae atu ana ki te pito whiwhi te tutuki i te "paepae ōwehenga tohu-ki-haruru", mā te whakawhānui ake i te awhe kitea - hei tauira, mā te whakanui ake i te mana tihi o te laser muka 1.5 μm mai i te 1kW ki te 5kW, i raro i ngā āhuatanga āhuarangi ōrite, ka taea te whakawhānui ake i te awhe kitea o ngā whāinga whakaata 10% mai i te 200 mita ki te 350 mita, ka whakatau tika i te mamae o te "kore e taea te ine tawhiti" i roto i ngā horopaki rangahau nui pēnei i ngā wāhi maunga me ngā koraha mō ngā waka rererangi kore-rangi.
② Whānuitanga o te pā (ns): ka taea te whakarerekē mai i te 1 ki te 10ns. Ko te whānuitanga o te pā he ≤ 0.5ns te rerekētanga o te pāmahana (-40~85 ℃) o te hua paerewa; ā, ka taea hoki te eke ki te whānuitanga o te pā he ≤ 0.2ns te rerekētanga. Ko tēnei tohu te "tauine wā" o te tika o te tawhiti, e tohu ana i te roanga o ngā pā taiaho. Ko te mātāpono tatau tawhiti mō te kimi i te waka rererangi ko "tawhiti=(tere mārama x wā haerenga-hoki pā)/2", nō reira ko te whānui o te pā te whakatau tika i te "tika ine wā". Ina whakaitihia te whānui o te pā, ka piki ake te "koi wā" o te pā, ā, ka tino whakaitihia te hapa wā i waenga i te "wā tuku pā" me te "wā whiwhi pā whakaata" i te pito whiwhi.
③ Te pumau o te roangaru: i roto i te 1pm/℃, ko te whānui o te raina i te pāmahana katoa o te 0.128nm te "pūnga tika" i raro i te pokanoa taiao, me te whānuitanga o te piki me te heke o te roangaru putanga laser me ngā huringa pāmahana me te ngaohiko. Ko te pūnaha kimi i roto i te roopu roangaru 1.5 μm te tikanga e whakamahi ana i te hangarau "whiwhi kanorau roangaru" te "interferometry" rānei hei whakapai ake i te tika, ā, ka taea e ngā piki me ngā heke o te roangaru te whakaputa tika i te rerekētanga o te paearu ine - hei tauira, ina mahi ana te waka rererangi i te teitei teitei, ka piki pea te pāmahana taiao mai i te -10 ℃ ki te 30 ℃. Mena ko te tauwehenga pāmahana roangaru o te laser muka 1.5 μm he 5pm/℃, ka piki te roangaru mā te 200pm, ā, ka piki ake te hapa ine tawhiti e rite ana mā te 0.3 mirimita (i ahu mai i te tātai hononga i waenga i te roangaru me te tere o te mārama). Ina koa i roto i te tirotiro raina hiko waka rererangi kore tangata, me ine i ngā tawhā tika pēnei i te heke o te waea me te tawhiti i waenga i te raina. Ka taea e te roangaru kore pumau te arahi ki te rerekētanga raraunga me te pā ki te aromatawai haumaru raina; Mā te hangarau raka roangaru 1.5 μm ka taea te whakahaere i te pumau o te roangaru i roto i te 1pm/℃, kia tika ai te kite i te taumata henimita ahakoa ngā huringa pāmahana.
④ Te mahi tahi a te tohu: Ko te "kaitaurite" i waenga i te tika me te whānuitanga i roto i ngā horopaki kitenga waka rererangi tūturu, ina kore ngā tohu e mahi motuhake, engari he hononga mahi tahi, he hononga here rānei. Hei tauira, mā te whakanui ake i te mana tihi ka taea te whakawhānui ake i te whānuitanga kitenga, engari me whakahaere te whānui o te pāorooro kia kore ai e heke te tika (me tutuki he taurite o te "mana teitei + pāorooro whaiti" mā te hangarau kōpeketanga pāorooro); Mā te arotau i te kounga o te hihi ka taea te whakapai ake i te whānuitanga me te tika i te wā kotahi (ka whakaitihia e te kukū hihi te maumau pūngao me te pokanoa ine i puta mai i ngā ira mārama taupatupatu i ngā tawhiti roa). Ko te painga o te taiaho muka 1.5 μm kei roto i tōna kaha ki te whakatutuki i te arotautanga tahi o te "mana tihi teitei (1-10 kW), te whānui pāorooro whaiti (1-10 ns), te kounga hihi teitei (M ²<1.5), me te pumau o te roangaru teitei (<1pm/℃)" mā roto i ngā āhuatanga ngaronga iti o te pāpāho muka me te hangarau whakarerekētanga pāorooro. Nā tēnei ka tutuki i a ia tētahi putanga rua o te "tawhiti roa (300-500 mita) + te tino tika (taumata henimita)" i roto i te kimi waka rererangi kore tangata, koinei anō hoki tōna whakataetae matua ki te whakakapi i ngā taiaho 905nm me te 1064nm tuku iho i roto i te rangahau waka rererangi kore tangata, te whakaora ohorere me ētahi atu āhuatanga.
