Ikhanda eligxilisa i-collimating lisebenzisa idivayisi yomshini njengeplatifomu esekelayo, futhi lihamba liye emuva naphambili ngedivayisi yomshini ukuze kufezwe ukushintshwa kwama-weld anezindlela ezahlukene. Ukunemba kokushintshwa kuncike ekunembeni kwe-actuator, ngakho-ke kunezinkinga ezifana nokunemba okuphansi, isivinini sokuphendula okuhamba kancane, kanye ne-inertia enkulu. Uhlelo lokuskena lwe-galvanometer lusebenzisa injini ukuphambukisa ilensi. Injini iqhutshwa ugesi othile futhi inezinzuzo zokunemba okuphezulu, i-inertia encane, kanye nokuphendula okusheshayo. Lapho umugqa wokukhanya ukhanyiswa ilensi ye-galvanometer, ukuphambukisa kwe-galvanometer kushintsha i-engeli yokubonakaliswa komugqa we-laser. Ngakho-ke, umugqa we-laser ungaskena noma iyiphi indlela ensimini yokuskena yokubuka ngohlelo lwe-galvanometer. Ikhanda eliqondile elisetshenziswa ohlelweni lokushintshwa kwamarobhothi luyisicelo esisekelwe kulesi simiso.
Izingxenye eziyinhloko ze-uhlelo lokuskena lwe-galvanometeryi-collimator yokwandisa ugongolo, ilensi yokugxila, i-galvanometer yokuskena ye-XY two-axis, ibhodi lokulawula kanye nohlelo lwesofthiwe yekhompyutha yomsingathi. I-galvanometer yokuskena ibhekisela kakhulu kumakhanda amabili okuskena e-XY galvanometer, aqhutshwa ama-servo motors asheshayo aphindaphindayo. Uhlelo lwe-servo olune-axis ezimbili luqhuba i-galvanometer yokuskena ye-XY dual-axis ukuze iphambuke ku-X-axis kanye ne-Y-axis ngokulandelana ngokuthumela izimpawu zomyalo kuma-servo motors e-X kanye ne-Y axis. Ngale ndlela, ngokunyakaza okuhlangene kwelensi yesibuko se-XY two-axis, uhlelo lokulawula lungaguqula isignali ngebhodi le-galvanometer ngokuya ngethempulethi yezithombe ezihleliwe zesofthiwe yekhompyutha yomsingathi kanye nemodi yendlela ebekiwe, futhi luhambe ngokushesha endizeni yomsebenzi ukuze lwakhe indlela yokuskena.

Ngokusho kobudlelwano besimo phakathi kwelensi yokugxila kanye ne-laser galvanometer, imodi yokuskena ye-galvanometer ingahlukaniswa ibe ukuskena okugxilile ngaphambili (isithombe sesobunxele) kanye nokuskena okugxilile emuva (isithombe sesokudla). Ngenxa yokuba khona komehluko wendlela yokukhanya lapho umsebe we-laser uphambuka uye ezindaweni ezahlukene (ibanga lokudlulisa umsebe lihlukile), indiza yokugxila ye-laser enkambisweni yokuskena yokugxila yangaphambilini iyindawo egobile ye-hemispherical, njengoba kuboniswe esithombeni sesobunxele. Indlela yokuskena egxilile emuva iboniswe esithombeni sesokudla, lapho ilensi eqondile iyilensi yensimu eyisicaba. Ilensi yensimu eyisicaba inomklamo okhethekile wokukhanya.
Uhlelo Lokushisela Lwerobhothi
Ngokungenisa ukulungiswa kokukhanya, indiza egxile kwe-hemispherical ye-laser beam ingalungiswa ibe yindiza. Ukuskena okugxile emuva kufaneleka kakhulu kwizicelo ezinezidingo eziphezulu zokunemba kokucubungula kanye nobubanzi obuncane bokucubungula, njengokumaka kwe-laser, ukushisela kwe-laser microstructure, njll. Njengoba indawo yokuskena ikhula, ukuvuleka kwelensi nakho kuyakhula. Ngenxa yemikhawulo yobuchwepheshe kanye nezinto ezibonakalayo, intengo yama-flense amakhulu e-aperture ibiza kakhulu, futhi lesi sixazululo asamukelwa. Ukuhlanganiswa kohlelo lokuskena lwe-galvanometer phambi kwelensi eqondiwe kanye nerobhothi eli-axis eziyisithupha kuyisisombululo esisebenzayo esinganciphisa ukuncika emishinini ye-galvanometer, futhi singaba nezinga elikhulu lokunemba kohlelo kanye nokuhambisana okuhle. Lesi sixazululo samukelwe ngabahlanganisi abaningi, okuvame ukubizwa ngokuthi ukushisela okundizayo. Ukushisela kwe-module busbar, okuhlanganisa nokuhlanzwa kwe-pole, kunezinhlelo zokusebenza zokundiza, ezingakhulisa ifomethi yokucubungula ngendlela eguquguqukayo nephumelelayo.
Kungakhathaliseki ukuthi ukuskena okugxile phambili noma ukuskena okugxile emuva, ukugxila komsebe we-laser akunakulawulwa ukuze kugxilwe ngokuguquguqukayo. Kwimodi yokuskena okugxile phambili, lapho umsebenzi ozocutshungulwa uncane, ilensi yokugxila inobubanzi obuthile bokujula kokugxila, ngakho-ke ingenza ukuskena okugxile ngefomethi encane. Kodwa-ke, lapho indiza ezoskenwa inkulu, amaphuzu aseduze nomngcele ngeke agxile futhi awakwazi ukugxila ebusweni bomsebenzi ozocutshungulwa ngoba udlula imikhawulo ephezulu nephansi yokujula kokugxila kwe-laser. Ngakho-ke, lapho umsebe we-laser kudingeka ugxile kahle kunoma yisiphi isikhundla endizeni yokuskena futhi insimu yokubuka inkulu, ukusetshenziswa kwelensi yobude obugxilile bokugxila akukwazi ukuhlangabezana nezidingo zokuskena.
Uhlelo lokugxila oluguquguqukayo luyisistimu yokukhanya enobude obuqondile obungashintshwa njengoba kudingeka. Ngakho-ke, ngokusebenzisa ilensi yokugxila eguquguqukayo ukuze kulungiswe umehluko wendlela yokukhanya, ilensi egobile (isandisi se-beam) ihamba ngokuqondile eceleni kwe-optical axis ukulawula indawo yokugxila, ngaleyo ndlela ithole isinxephezelo esiguquguqukayo somehluko wendlela yokukhanya ebusweni okufanele bucutshungulwe ezindaweni ezahlukene. Uma kuqhathaniswa ne-galvanometer ye-2D, ukwakheka kwe-galvanometer ye-3D kunezela kakhulu "uhlelo lwe-optical lwe-Z-axis", oluvumela i-galvanometer ye-3D ukuthi ishintshe ngokukhululekile indawo yokugxila ngesikhathi senqubo yokuxhuma futhi yenze ukushisela kwendawo egobile, ngaphandle kwesidingo sokulungisa indawo yokugxila kokushisela ngokushintsha ukuphakama kwesithwali njengethuluzi lomshini noma irobhothi njenge-galvanometer ye-2D.
Uhlelo lokugxila olunamandla lungashintsha inani le-defocus, lushintshe usayizi wendawo, lubone ukulungiswa kokugxila kwe-Z-axis, kanye nokucutshungulwa okunezinhlangothi ezintathu.
Ibanga lokusebenza lichazwa njengebanga elisuka emaphethelweni angaphambili kakhulu elensi kuya endizeni egxile noma endizeni yokuskena yenhloso. Qaphela ukuthi ungadidanisi lokhu nobude obugxile obusebenzayo (i-EFL) benhloso. Lokhu kulinganiswa kusukela endizeni eyinhloko, indizeni ecatshangelwayo lapho lonke uhlelo lwelensi luthathwa khona ukuthi luyaphambuka, kuya endizeni egxile yesistimu yokukhanya.
