Te Whakamahinga o te Taiaho Ārahi Kotahi Auautanga hei Ine Tika i te Whakararuraru Ngaru Mārama

Te tono oTaiaho Ārahi-Aunoa Kotahii roto i te Ine Tika o te Whakararuraru Ngaru Mārama
Te tono o te auau kotahirēhia haurua-iraKa matapakihia te kaupapa ine tika pērā i ngā waea wai muka whatu me ngā ine whakarongo whenua, ā, ka tātarihia hōhonu te pānga matua o te mahi taiaho ki te mahi a ngā pūnaha ine.

Hanganga matua me te mātāpono mahi o te pūnaha: Ko te pūnaha waea wai muka whatu he mea hanga nui mai i te pane pūoko me te ine whakawhiti (hei tauira, te ine whakawhiti MZ). Ko te mātāpono taketake ko te tohu oro (te pēhanga oro Δp) e pā ana ki te pane pūoko, ka puta he huringa ki te roa me te taupū whakaata o te muka pūoko e takai ana i te rango tuwhera, ā, ka puta he huringa ki te ara whatu. Ka kitea tēnei huringa ara whatu iti (arā, te huringa ā-wāhanga) me te tino aro nui e te ine whakawhiti.

1. Upoko pūoko: Ko tana mahi matua he huri i ngā wiri oro hei huringa i te ara whatu o te interferometer. E pā ana te tauwehenga aro s ki ngā āhuatanga pēnei i te roa o te muka L, ā, he pai ngā muka aro roa ake hei whakapai ake i te aro o te pūnaha.
2. Interferometer: Koinei te "patu pai rawa atu" mō te kite i ngā huringa iti o te āhua. He hononga cosine te kaha o te mārama putanga ki te rerekētanga āhua. Mā te whakau i te piro āhua tūmau φ₀ i te pūwāhi mahi orthogonal ((m+1/2) π), ka taea e te pūnaha te whakatutuki i te aro nui ki te kite.
3. Ngā tawhā matua o te pūtake mārama e pā ana ki te mahi a te pūnaha: Ka arotahi te tuhinga ki te tātari i ngā herenga o te mahi taiaho ki te whakatutuki i te taumira ā-wāhanga teitei (me te whāinga o ≤ 1 μ rad).
4. Reeraharuru auau me te whānui raina: Ka taea e te haruru auau o te taiaho te whakaputa haruru ā-wāhanga pokanoa, ā, ka whakaitihia te tirohanga o ngā taha pokanoa. Mō te interferometer me te rerekētanga ara whatu o te 1 mita, kia tutuki ai he taumira ā-wāhanga o te 1 μ rad, me iti iho te whānui raina o te taiaho i te 30 Hz. He whakaritenga tino nui tēnei mō te pumau auau o tepūtake mārama.
5. Haruru kaha o te taiaho: Ka hurihia tika te haruru kaha whanaunga (RIN) o te taiaho hei hapa ā-wāhanga o te tohu pokanoa. Hei whakatutuki i te taumira ā-wāhanga o te 1 μ rad i te mana rama kimi noa (~100 μ W), me whakaiti te RIN o te taiaho ki raro iho i te -120 dB. He whakaritenga tino nui tēnei mō te pumau o te kaha o te pūtake rama.

Hei whakarāpopototanga, mā te tātari i te pūnaha waea wai muka whatu, ka whakamāramahia ngā whakaritenga pakari mō te pūtake mārama matua – te taiaho haurua-ira kotahi te auau – e pā ana ki te whānui rārangi tino whaiti (te pumau auau teitei) me te haruru tino iti te kaha i roto i te ine tika i runga i te mātāpono pokanoa, ā, ka whakaatuhia ngā wero pumau auau taiaho e pā ana ki ngā tono pūnaha tauine nui.
