Whakarāpopototanga Taipitopito o ngā Upoko Whakarewa Taiaho Rere

Whakarāpopototanga Taipitopito oNgā Upoko Whakarewa Rere Rere

E kapi ana i ngā ingoa wāhanga, ngā whakamāramatanga, ngā mātāpono, ngā tawhā hoahoa me ngā tātaitanga tātai, ā, e tika ana hoki kiwhakarewa matawai tere-teitei(pērā i ngā pūnaha galvanometer) me ngā tono whakarewa mamao rānei.

1. Te Hanganga me te Whakamāramatanga o ngā Upoko Whakarewa Rere Rere Rere

Mā te whakarewa rere (Whakarewa Taiaho Matawai) ka tutuki te arotahi hihiri mā te whakamahi i te galvanometer tere-teitei e whakaata ana i ngā hihi taiaho, ā, he pai mō te wāhi nui me tewhakarewa tere-teiteiKo ōna wāhanga matua koia ēnei:

1. Wāhanga Whakakotahitanga Hiko

Kaiwhakakorikori

Mahi: Tahurihia te putanga taiaho rerekē (NA=0.1~0.22) e te muka whatu hei hihi whakarara.

Ngā tawhā matua: Te roa arotahi fcoll, te diameter hihi kua whakawhāitihia Dcoll.

Tātai：

1.2 Pūnaha Matawai Galvanometer

Ngā Whakaata Galvo tuaka-X/Y

Mahi: Hurihia te ahunga o te hihi mārama mā roto i ngā whakaata hurihuri tere-teitei hei whakatutuki i te matawai papa rua-ahu.

Ngā tawhā matua: Te tere matawai (te tikanga ≥10m/s), te tika o te tūnga tāruarua (<±5μrad), te rahi o te whakaata (me kapi te diameter o te hihi Dcoll).

Mōtaita karawana: Mōtaita servo, mōtaita karawana rānei me te wā urupare <1ms.

1.3 Wāhanga Arotahi Hihiri (Arotahi F-Theta, Arotahi Galvanometer rānei + Arotahi Papa-Papatahi)

Arotahi F-Theta

Mahi: Tahurihia te koki piko o te galvanometer hei nekehanga rārangi i runga i te papa hei pupuri i te ōritetanga arotahi.

Ngā tātai matua:

2. Te Mātāpono Mahi

Ara hihi: Taiaho → Kaiwhakapiri → Karanimita X → Karanimita Y → Karāhe F-Theta → Mata o te mea mahi.

Te arotahi hihiri:

Ina ko te koki piko o te galvanometer he θ, ka hurihia te tūranga arotahi (x, y) e te arotahi F-Theta penei:

3. Ngā Tawhā Hoahoa Matua me ngā Tātai

3.1 Tātaitanga Rahi Ira

Diameter o te ira arotahi d (rohenga whakarara):

3.2 Te Awhe Matawai me te Koki Galvanometer

Te whānuitanga matawai mōrahi L:

3.3 Te Tere me te Whakaterenga o te Whakarewa

Tere rārangi v

3.4 Te Hōhonutanga o te Arotahi (DOF)

3.5 Te Kiato Mana me te Whakauru Pūngao

Te mātotoru o te mana I:

Te mātotoru pūngao E (whakapiripiri pātere):

4. Ngā Hē me te Hoahoa Arotau

4.1 Te Whakatikatika i te Hē o te Arotahi F-Theta

Te Whakapōturi: Me tutuki i a ia te r∝θ, ā, me iti iho i te 0.1% te whakapōturi kore-raina.

Pīkoki āpure: Hoahoahia he āpure papatahi mā roto i ngā rōpū maha-arotahi.

4.2 Hapa Tukutahitanga o te Galvanometer

Me iti ake i te 1μs te whakaroa o te karawaka X/Y hei karo i ngā ira porowhita.

5. Tauira o te Tukanga Hoahoa

Ngā whakaritenga tāuru: Te whānuitanga matawai L, te rahi o te ira d, te tere whakarewa v. Tīpakohia te arotahi F-Theta: Whakatauhia te fθ e ai ki te L=2fθtan(θmax).

Tātaihia ngā tawhā o te karawaka: Te tere koki ω=v/fθ, ā, manatokohia te mahi a te karawaka.

Manatokohia te kounga o te ira: Arotauhia ngā hapa o te rōpū arotahi mā Zemax/OpticStudio.

6. Ngā Whakatūpato

Te whakahaere wera: Me whakamatao wai ngā karawana me ngā karāhe i raro i te mana nui (pērā i te >1kW).

Parenga ā-tukinga: Me aukati ohorere ngā galvanometers hei karo i te tukinga ā-mīhini.

Whakatikatika: Whakatikatikahia te hononga ara whatu i ia wā (te peka <0.05mm).
