Madaxa diirada saaraya waxa uu isticmaalaa qalab makaanik ah sidii madal kaalmaysa, oo waxa uu hore iyo gadaal u maraa qalabka farsamada si uu u gaadho alxanka alxanka ee leh habab kala duwan. Saxnaanta alxanka waxay kuxirantahay saxnaanta jileeyaha, sidaa darteed waxaa jira dhibaatooyin sida saxnaanta hoose, xawaaraha jawaab celinta oo gaabis ah, iyo firfircooni la'aan weyn. Nidaamka iskaanka galvanometer wuxuu isticmaalaa matoor si uu u leexiyo muraayadda. Matoorka waxaa wada hadda oo gaar ah wuxuuna leeyahay faa'iidooyinka saxnaanta sare, firfircoonida yar, iyo jawaab celinta degdega ah. Marka laydhka iftiinka lagu iftiimiyo muraayadda galvanometer, leexashada galvanometerku waxay beddeshaa xagasha muraayadda laydhka. Sidaa darteed, laydhka laysarka wuxuu baari karaa raad kasta oo ku yaal goobta sawirka ee muuqaalka iyada oo loo marayo nidaamka galvanometer. Madaxa toosan ee loo isticmaalo nidaamka alxanka robotiga waa codsi ku salaysan mabda'an.
Qaybaha ugu muhiimsan eenidaamka iskaanka galvanometerwaa collimaator fidinta beam, lens diiradda, XY laba dhidib iskaanka galvanometer, guddiga kantaroolka iyo nidaamka software computer martigeliyaha. Galvanometer-ka sawirku wuxuu inta badan tilmaamayaa labada madax ee iskaanka XY galvanometer, kuwaas oo ay wataan matoorada servo ee xawaaraha sare leh. Nidaamka servo dual-axis wuxuu wadaa galvanometer-ka dhidibka-dual-axis scanning galvanometer si uu u leexiyo dhidibka X iyo dhidibka Y- siday u kala horreeyaan isagoo u diraya calaamadaha amarka matoorada servo axis X iyo Y. Sidan oo kale, iyada oo loo marayo dhaqdhaqaaqa isku dhafan ee muraayadda muraayadda labada dhidib ee XY, nidaamka xakamaynta wuxuu u rogi karaa calaamadda iyada oo loo marayo guddiga galvanometer sida ku cad qaabka sawirada hore ee software kombiyuutarka martida loo yahay iyo habka loo dejiyay, oo si dhakhso ah u dhaqaaqo. on diyaaradda of workpiece si ay u sameeyaan raad sawir.

Marka loo eego xidhiidhka ka dhexeeya lens-fiirinta iyo galvanometer-ka laysarka, qaabka iskaanka galvanometerka waxa loo qaybin karaa iskaanka diirada saaraya hore (sawirka bidix) iyo dib u fiirsashada iskaanka (sawirka midig). Sababtoo ah jiritaanka kala duwanaanshaha dariiqa indhaha marka laydhka laysarka uu u leexiyo meelo kala duwan (masaafada gudbinta iftiinka waa ka duwan tahay), diyaaradda focal laser ee geeddi-socodkii hore ee diiradda saarista waa dusha qalooca ah, sida ku cad shaxanka bidix. Habka fiirsashada ee dhabarka waxaa lagu muujiyey shaxanka saxda ah, kaas oo muraayadda ujeedadu tahay muraayad bannaan oo siman. Muraayada bannaan ee fidsan ayaa leh nashqad muuqaal gaar ah.
Marka la soo bandhigo hagaajinta indhaha, diyaaradda hemispherical focal of beam laser waxaa lagu hagaajin karaa diyaarad. Iskaanka diiradda Back inta badan ku haboon codsiyada leh shuruudaha saxsanaanta processing sare iyo kala duwan ee processing yar, sida calaamadaynta laser, alxanka microstructure laser, iwm Sida aagga iskaanka u kordho, daloolin ee lens sidoo kale kordhiyaa. Sababtoo ah xaddidaadaha farsamada iyo maadada, qiimaha flenses-ka weyn waa mid aad qaali u ah, xalkan lama aqbalin. Isku darka nidaamka iskaanka galvanometer ee hore ee muraayadda ujeedada iyo robot-ka lix dhidibka ah waa xal macquul ah oo yarayn kara ku tiirsanaanta qalabka galvanometer, oo yeelan kara heer aad u sarreeya oo sax ah nidaamka iyo waafaqsanaanta wanaagsan. Xalkan waxaa qaatay inta badan is-dhexgalka, kaas oo inta badan loo yaqaan alxanka duulaya. Alxanka baska moduleka, oo ay ku jiraan nadiifinta tiirka, ayaa leh codsiyo duulaya, kuwaas oo si dabacsan oo hufan u kordhin kara qaabka habaynta.
Haddi ay tahay iskaanka hore u foojigan ama sawirka dambe ee diirada saaraya, diirada laydhka laysarka laguma xakamayn karo diirada firfircoonida leh. Qaabka iskaanka hore-u-fiirinta, marka qaybta shaqada ee la farsamaynayo ay yar tahay, muraayadda diiradda la saarayo waxay leedahay qoto dheer oo qotodheer oo gaar ah, si ay u fulin karto sawir-qaadista qaab yar. Si kastaba ha ahaatee, marka diyaarad in la sawiro waa weyn, dhibcood u dhow durugsan noqon doonaa diiradda oo aan diiradda saari karin dusha workpiece in la farsameeyo sababtoo ah waxa ay dhaaftay xadka sare iyo hoose ee qoto dheer focal laser. Sidaa darteed, marka laydhka laysarka looga baahan yahay inuu si fiican u foojignaado meel kasta oo ka mid ah diyaaradda sawir-qaadista iyo goobta muuqaalku waa weyn yahay, isticmaalka muraayadda dhererka dhererka go'an ma buuxin karto shuruudaha iskaanka.
Nidaamka diirada saaraya firfircooni waa nidaam indho-indheyn kaas oo dhererkiisa focal la bedeli karo marka loo baahdo. Sidaa darteed, adoo isticmaalaya muraayad diirada saaraya firfircoonida si loo magdhabo farqiga u dhexeeya jidka indhaha, lens-ka concave (ballaare beam) wuxuu si toos ah ugu socdaa dhidibka indhaha si uu u xakameeyo booska diiradda, sidaas darteed lagu gaaro magdhow firfircoon ee farqiga waddada indhaha ee dusha si loo farsameeyo. jagooyin kala duwan. Marka la barbardhigo galvanometer-ka 2D, halabuurka galvanometer-ka 3D wuxuu inta badan ku daraa "nidaamka indhaha ee dhidibka ah", kaas oo u oggolaanaya galvanometer 3D inuu si xor ah u beddelo booska focal inta lagu jiro habka alxanka oo uu sameeyo alxanka dusha sare ee qalloocan, iyada oo aan loo baahnayn in la hagaajiyo alxanka booska diirada la beddelo dhererka sidaha sida qalabka mashiinka ama robot sida galvanometer 2D ah.
Nidaamka diirada saaraya firfircooni wuxuu bedeli karaa qadarka goynta, beddelka cabbirka booska, xaqiiqo hagaajinta dhidigga Z, iyo habaynta saddex-geesoodka ah.
Fogaanta shaqada waxaa lagu qeexaa masaafada u jirta cidhifka hore ee farsamada ugu badan ee lenska ilaa diyaaradda focal ama diyaaradda sawirka ujeedada. Ka digtoonow inaad tan ku wareerin dhererka fogaanta waxtarka leh (EFL) ee ujeedada. Tan waxaa laga cabbiraa diyaaradda ugu muhiimsan, diyaarad mala awaal ah oo nidaamka lens-ka oo dhan loo maleynayo inuu dib u soo laabanayo, oo ku wajahan diyaaradda focal ee habka indhaha.
