Ko te matawai taiaho, e kiia ana hoki ko te galvanometer taiaho, he mea hanga mai i te pane matawai whatu XY, te whakakaha puku hiko me te karāhe whakaata whatu. Ko te tohu e tukuna ana e te kaiwhakahaere rorohiko ka panaia te pane matawai whatu mā roto i te ara iahiko whakakaha taraiwa, ā, mā reira ka whakahaere i te piko o te hihi taiaho i roto i te papa XY. I roto i te kōrero māmā, ko te galvanometer he galvanometer matawai e whakamahia ana i roto i te umanga taiaho. Ko tōna kupu ngaio ko te galvanometer matawai tere-teitei pūnaha matawai Galvo. Ka taea hoki te kī ko te galvanometer e kiia nei ko te ammeter. Ko tōna whakaaro hoahoa e whai katoa ana i te tikanga hoahoa o te ammeter. Ka whakakapia e te karāhe te ngira, ā, ka whakakapia te tohu o te tirotiro e te tohu -5V-5V, -10V-+10V DC rānei e whakahaerehia ana e te rorohiko. , hei whakaoti i te mahi kua whakaritea. Pērā i te pūnaha matawai whakaata hurihuri, ka whakamahia e tēnei pūnaha whakahaere noa he takirua whakaata hoki. Ko te rerekētanga ko te motuka stepper e panaia ana tēnei huinga karāhe ka whakakapia e te motuka servo. I roto i tēnei pūnaha whakahaere, ka whakamahia he pūoko tūnga. Ko te whakaaro hoahoa me te porowhita urupare kino ka whakarite anō i te tika o te pūnaha, ā, ka eke te tere matawai me te tika o te tūnga auau o te pūnaha katoa ki tētahi taumata hou. Ko te pane tohu matawai galvanometer he mea hanga nui mai i te whakaata matawai XY, te arotahi mara, te galvanometer me te pūmanawa tohu rorohiko. Tīpakohia ngā wāhanga whatu e rite ana kia rite ki ngā roangaru taiaho rerekē. Ko ngā kōwhiringa e pā ana ko ngā whakawhanui hihi taiaho, ngā taiaho, me ētahi atu. I roto i te pūnaha whakaaturanga taiaho, ko te āhua ngaru o te matawai whatu he matawai whārite, ā, ko te tere matawai o te pūnaha ka whakatau i te pumau o te tauira taiaho. I ngā tau tata nei, kua whakawhanakehia ngā matawai tere-teitei, me ngā tere matawai e eke ana ki te 45,000 ngā tohu/hekona, e taea ai te whakaatu i ngā pakiwaituhi taiaho uaua.
5.1 Hononga whakarewa galvanometer taiaho
5.1.1 Te whakamāramatanga me te hanganga o te hononga whakarewa galvanometer:
Ka whakamahia e te pane arotahi collimation tētahi taputapu miihini hei tūāpapa tautoko. Ka neke whakamua, ka neke whakamua te taputapu miihini hei whakatutuki i te whakarewa o ngā whakarewanga ara rerekē. Ko te tika o te whakarewanga e whakawhirinaki ana ki te tika o te actuator, nō reira he raruraru pēnei i te iti o te tika, te puhoi o te tere urupare, me te nui o te inertia. Ka whakamahia e te pūnaha matawai galvanometer he motuka hei kawe i te arotahi mō te whakapiko. Ka peia te motuka e tētahi iahiko, ā, he painga o te tino tika, te iti o te inertia, me te tere o te urupare. Ina whakamāramahia te hihi ki te arotahi galvanometer, ka hurihia e te whakapiko o te galvanometer te hihi laser. Nō reira, ka taea e te hihi laser te matawai i tētahi ara i roto i te tirohanga matawai mā te pūnaha galvanometer.
Ko ngā wāhanga matua o te pūnaha matawai galvanometer ko te collimator whānui hihi, te arotahi arotahi, te galvanometer matawai tuaka-rua XY, te papa whakahaere me te pūnaha pūmanawa rorohiko manaaki. Ko te galvanometer matawai e pā ana ki ngā pane matawai galvanometer XY e rua, e peia ana e ngā motuka servo tauutuutu tere-teitei. Ka peia e te pūnaha servo tuaka-rua te galvanometer matawai tuaka-rua XY kia huri i te tuaka-X me te tuaka-Y mā te tuku tohu whakahau ki ngā motuka servo tuaka-X me te tuaka-Y. Mā tēnei, mā te nekehanga ngātahi o te arotahi whakaata tuaka-rua XY, ka taea e te pūnaha whakahaere te huri i te tohu mā te papa galvanometer kia rite ki te tauira whakairoiro kua whakaritea o te pūmanawa rorohiko manaaki kia rite ki te ara kua whakaritea, ka tere te neke i runga i te papa mahi hei hanga i te ara matawai.
5.1.2 Te whakarōpūtanga o ngā hononga whakarewa galvanometer:
1. Arotahi matawai arotahi mua
E ai ki te whanaungatanga tūnga i waenga i te arotahi arotahi me te karawaka reera, ka taea te wehewehe i te aratau matawai o te karawaka reera ki te matawai arotahi o mua (Pikitia 1 i raro) me te matawai arotahi arotahi o muri (Pikitia 2 i raro). Nā te rerekētanga o te ara whatu ina hurihia te hihi reera ki ngā tūranga rerekē (he rerekē te tawhiti tuku hihi), ko te mata arotahi reera i te wā o te tukanga matawai aratau arotahi o mua he mata porowhita, e whakaaturia ana i te pikitia maui. Ko te tikanga matawai muri-arotahi e whakaaturia ana i te pikitia i te taha matau. Ko te arotahi whāinga he arotahi mahere-F. He hoahoa whatu motuhake tō te whakaata mahere-F. Mā te whakauru i te whakatikatika whatu, ka taea te whakarite i te mata arotahi porowhita o te hihi reera kia papatahi. Ko te matawai muri-arotahi he mea pai mō ngā tono e hiahia ana ki te tika tukatuka teitei me te whānuitanga tukatuka iti, pēnei i te tohu reera, te whakarewa hanganga moroiti reera, me ētahi atu.
2.Karāhe matawai arotahi whakamuri
I te piki haere o te horahanga matawai, ka piki ake hoki te pūaha o te karāhe f-theta. Nā ngā herenga hangarau me ngā rauemi, he tino utu nui ngā karāhe f-theta pūaha nui, ā, kāore e whakaaetia tēnei otinga. Ko te pūnaha matawai ine karawaka o mua o te karāhe whāinga me te karetao tuaka-ono he otinga whaihua, ka taea te whakaiti i te whakawhirinaki ki ngā taputapu ine karawaka, he nui te tika o te pūnaha, ā, he pai te hototahi. Kua whakamahia tēnei otinga e te nuinga o ngā kaiwhakauru. Ko te tango, e kiia ana ko te whakarewa rere. Ko te whakarewa o te pae pahi kōwae, tae atu ki te horoi pou, he tono rere, ka taea te whakanui ake i te whānui tukatuka me te ngāwari me te whai hua.
3.3D galvanometer:
Ahakoa he matawai arotahi-mua, he matawai arotahi-muri rānei, kāore e taea te whakahaere i te arotahi o te hihi reera mō te arotahi hihiri. Mō te aratau matawai arotahi mua, ina iti te mea mahi hei tukatuka, he whānuitanga hohonu arotahi tō te arotahi arotahi, nō reira ka taea e ia te mahi matawai arotahi me te whakatakotoranga iti. Heoi, ina nui te papa e matawaihia ana, ka kore e arotahi ngā pūwāhi e tata ana ki te taha, ā, kāore e taea te arotahi ki te mata o te mea mahi hei tukatuka nā te mea kua nui ake i te whānuitanga hohonu o te arotahi reera. Nō reira, ina hiahiatia kia arotahi pai te hihi reera ki tētahi tūranga i runga i te papa matawai, ā, he nui te mara tirohanga, kāore e taea e te whakamahinga o te arotahi roa arotahi pumau te whakatutuki i ngā whakaritenga matawai. Ko te pūnaha arotahi hihiri he huinga pūnaha whatu ka taea te whakarerekē i te roa arotahi ina hiahiatia. Nō reira, e whakaaro ana ngā kairangahau kia whakamahia he arotahi arotahi hihiri hei utu mō te rerekētanga ara whatu, me te whakamahi i te arotahi kōpiko (whakawhānui hihi) hei neke raina i te tuaka whatu hei whakahaere i te tūranga arotahi me te whakatutuki i te mata e tukatukahia ana ka utu hihiri mō te rerekētanga ara whatu i ngā tūranga rerekē. Ki te whakataurite ki te karawaka 2D, ko te hanganga o te karawaka 3D he "pūnaha whatu tuaka-Z", kia taea ai e te karawaka 3D te whakarerekē noa i te tūranga arotahi i te wā o te tukanga whakarewa me te mahi whakarewa mata piko ā-wāhi, me te kore e hiahiatia te whakarerekē i te kawe pēnei i te taputapu mīhini, me ētahi atu pēnei i te karawaka 2D. Ko te teitei o te karetao te mea e whakamahia ana hei whakarerekē i te tūranga arotahi whakarewa.
