Matawai taiaho, e kiia ana ko te galvanometer taiaho, kei roto ko te upoko matawai matawai XY, te whakakaha puku hiko me te arotahi whakaata whatu.Ko te tohu e whakaratohia ana e te kaiwhakahaere rorohiko ka peia te upoko matawai mata i roto i te ara iahiko whakakaha taraiwa, na reira ka whakahaere i te paheketanga o te kurupae laser i te rererangi XY.Ko te korero noa, ko te galvanometer he galvanometer matawai e whakamahia ana i roto i te ahumahi laser.Ko tana kupu ngaio e kiia ana ko te galvanometer matawai tere teitei te punaha matawai Galvo.Ka taea hoki te kiia ko te galvanometer he ammeter.Ko tana whakaaro hoahoa e whai ana i te tikanga hoahoa o te ammeter.Ka whakakapihia e te arotahi te ngira, ka whakakapihia te tohu o te tirotiro ki te tohu -5V-5V ranei -10V-+10V DC e whakahaeretia ana e te rorohiko., ki te whakaoti i te mahi kua whakaritea.Pērā i te punaha matawai whakaata hurihuri, ka whakamahia e tenei punaha whakahaere nga whakaata e rua.Ko te rereketanga ko te motuka hikoi e peia ana tenei huinga arotahi ka whakakapihia e te motuka servo.I roto i tenei punaha whakahaere, ka whakamahia he pukoro tuunga Ko te whakaaro hoahoa me te hurihanga urupare kino e whakarite ana i te tika o te punaha, me te tere matawai me te tika o te tuunga o te punaha katoa ka eke ki te taumata hou.Ko te upoko tohu matawai galvanometer ko te nuinga o te XY whakaata matawai, te arotahi mara, te galvanometer me te rorohiko tohu tohu rorohiko.Tīpakohia nga waahanga whatu e rite ana ki nga roangaru laser rereke.Ko nga whiringa e pa ana ko nga kaiwhakawhanui kurupae laser, lasers, me etahi atu. I roto i te punaha whakaaturanga laser, ko te ahua ngaru o te matawai matawai he matawai vector, a ko te tere o te matawai o te punaha ka whakatau i te pumau o te tauira laser.I nga tau tata nei, kua whakawhanakehia nga matawai tere tere, me nga tere matawai ka eke ki te 45,000 nga tohu / hekona, e taea ai te whakaatu i nga whakakoritanga laser matatini.
5.1 taiaho galvanometer fehokotaki'anga hononga
5.1.1 Whakamaramatanga me te hanganga o te hononga hononga galvanometer:
Ko te upoko e arotahi ana ki te whakakotahitanga e whakamahi ana i tetahi taputapu miihini hei papa tautoko.Ko te taputapu miihini ka neke whakamuri ki te whakatutuki i nga hononga rereke rereke.Ko te tika o te whakapiri ka whakawhirinaki ki te tika o te kaitahuri, na reira he raruraru penei i te iti o te tika, te tere whakautu puhoi, me te inertia nui.Ka whakamahia e te punaha matawai galvanometer he motuka hei kawe i te arotahi mo te paheketanga.Ko te motuka e peia ana e tetahi o naianei me nga painga o te tino tika, te iti o te inertia, me te whakautu tere.I te wa e whakamaramahia ana te kurupae i runga i te arotahi galvanometer, ka huri te paheketanga o te galvanometer i te kurupae laser.Na reira, ka taea e te kurupae laser te matawai i tetahi huarahi i roto i te mara matawai o te tirohanga ma te punaha galvanometer.
Ko nga waahanga matua o te punaha matawai galvanometer he collimator roha kurupae, arotahi arotahi, XY rua-tuaka matawai galvanometer, poari whakahaere me te punaha rorohiko rorohiko manaaki.Ko te galvanometer matawai e pa ana ki nga upoko matawai XY galvanometer e rua, e peia ana e nga motuka servo tere tere.Ko te punaha servo tuaka-rua ka peia te galvanometer matawai tuaka-rua XY ki te whakaneke haere i te tuaka-X me te tuaka-Y ma te tuku tohu whakahau ki nga motuka servo tuaka-X me te Y.I tenei ara, na roto i te nekehanga whakakotahi o te XY rua-tuaka whakaata arotahi, ka taea e te punaha whakahaere te huri i te tohu ma te papa galvanometer kia rite ki te tauira whakairoiro tatūkē o te rorohiko rorohiko kaihautū kia rite ki te huarahi kua whakaritea, ka tere haere i runga i te rererangi mahi hei hanga i te huarahi matawai.
5.1.2 Whakar
1. Mua arotahi matawai arotahi
E ai ki te hononga tuunga i waenga i te arotahi arotahi me te galvanometer taiaho, ka taea te wehea te aratau matawai o te galvanometer ki te matawai arotahi o mua (Whakaahua 1 kei raro) me te matawai arotahi arotahi ki muri (Whakaahua 2 kei raro).Na te mea he rerekee te ara whatu i te wa e paopao ana te kurupae laser ki nga waahi rereke (he rereke te tawhiti o te tuku kurupae), ko te mata arotahi taiaho i te wa o te tukanga matawai aratau arotahi o mua he mata hemispherical, penei i te ahua maui.Ko te tikanga matawai i muri i te arotahi ka whakaatuhia ki te pikitia kei te taha matau.Ko te arotahi whainga he arotahi mahere-F.He hoahoa whatu motuhake te whakaata F- mahere.Ma te whakauru i te whakatikatika whatu, ka taea te whakatika i te mata o te mata o te kurupae laser ki te papatahi.Ko te tirotiro i muri i te arotahi he tino pai mo nga tono e hiahia ana kia tika te tukatuka me te awhe tukatuka iti, penei i te tohu laser, te miihini miihini laser, me etahi atu.
2.Arotahi arotahi matawai muri
I te pikinga o te waahi matawai, ka piki hoki te kohao o te arotahi f-theta.Na te iti o te hangarau me te rauemi, he tino utu nga arotahi f-theta nui-aperture, a kaore i te whakaaetia tenei otinga.Ko te punaha matawai galvanometer o mua me te karetao tuaka ono he otinga tino pai, ka taea te whakaiti i te whakawhirinaki ki nga taputapu galvanometer, he nui te tika o te punaha, he pai te hototahi.Kua tangohia tenei otinga e te nuinga o te hunga whakauru.Adopt, e kiia ana ko te welding rere.Ko te whakapiringa o te pae pahi, tae atu ki te horoi pou, he tono rere, ka taea te whakanui ake i te whanui tukatuka kia ngawari me te pai.
3.3D galvanometer:
Ahakoa he matawai-a-mua, he matawai-a-muri ranei, kaore e taea te whakahaere i te arotahi o te kurupae laser mo te arotahi hihiri.Mo te aratau matawai arotahi o mua, ina he iti te mea mahi ka tukatukahia, he awhe hohonu te arotahi o te arotahi arotahi, na reira ka taea e ia te mahi matawai arotahi me te whakatakotoranga iti.Heoi, ka nui te waka rererangi ka karapahia, ko nga tohu e tata ana ki te taha taha ka kore e aro ki runga i te mata o te mea mahi hei tukatuka na te mea ka nui ake te awhe hohonu o te arotahi laser.Na reira, ka hiahiatia te kurupae laser kia pai te arotahi ki tetahi waahi i runga i te rererangi matawai me te waahi o te tirohanga he nui, kaore e taea e te whakamahinga o te arotahi te roa o te arotahi ki te whakatutuki i nga whakaritenga matawai.Ko te punaha arotahi hihiri he huinga o nga punaha whatu ka huri te roa o te arotahi ina hiahiatia.Na reira, ka whakaaro nga kairangahau ki te whakamahi i te arotahi arotahi hihiri ki te utu mo te rereketanga o te ara whatu, me te whakamahi i te arotahi concave (beam expander) ki te neke ahorangi haere i te tuaka whatu ki te whakahaere i te tūnga arotahi me te whakatutuki Ko te mata ki te tukatuka hihiri utu mo te whatu. rerekētanga ara i ngā tūnga rerekē.Ka whakatauritea ki te galvanometer 2D, ko te hanganga o te galvanometer 3D te nuinga ka taapirihia he "Z-axis optical system", kia taea ai e te galvanometer 3D te whakarereke noa i te waahi arotahi i te wa o te mahi whakahiato me te mahi i te mokowhiti mokowhiti mata kopikopiko, me te kore e whakarereke. te kaikawe penei i te taputapu miihini, me etahi atu penei i te galvanometer 2D.Ko te teitei o te karetao ka whakamahia hei whakatika i te tuunga arotahi whakapiri.
