Real-time sensor cov ntaub ntawv, suav nrog teb encoders, yog qhov tseem ceeb rau sub-micron positional precision. Tsis tas li ntawd, lub scanner cov lus teb thiab kev ruaj ntseg nyob ntawm rotor inertia thiab electromagnetic dampening.
Daim iav
Galvanometer laser scanners coj lub teeb laser ntawm daim iav. Cov khoom siv iav thiab txheej yog qhov tseem ceeb. Cov iav tuaj yeem tsim los ntawm beryllium lossis silicon carbide kom txo qis inertia thiab ceev txav. Cov ntaub ntawv dielectric sib phim rau lub laser lub wavelength yog coated rau ntawm qhov chaw reflecting kom muaj kev cuam tshuam thiab txo lub zog poob. Daim iav cov duab thiab qhov loj me hloov lub laser beam lub focal nta. Nws cuam tshuam rau lub scanner lub peev xwm los mloog zoo rau cov hom phiaj sib txawv.
Servo Tsav Board
Lub galvanometer laser scanner lub servo tsav lub rooj tsavxwm tswj tag nrho cov haujlwm scanning. Nws suav nrog cov tsav tsheb tsav uas muab galvanometer motors nrog tam sim no nyob ntawm kev tswj software input. Lub rooj tsavxwm tsim tsim txwv tsis pub muaj suab nrov hauv hluav taws xob, uas tuaj yeem cuam tshuam kev txheeb xyuas qhov tseeb. Cov rooj tsav tsheb kuj tseem tuaj yeem siv cov kev kwv yees tswj cov txheej txheem nyuaj kom suav nrog kev ua haujlwm tsis zoo thiab tsis muaj zog. Cov yam ntxwv no txhawb nqa cov lus tsa suab thiab lub sijhawm cov tshuaj tiv thaiv rau kev kub ceev, siab-precision scanning daim ntawv thov.
Cov yam ntxwv tseem ceeb los nrhiav hauv Galvanometer Laser Scanner
Ceev
Xav txog cov iav 'qhov siab tshaj plaws spinning ceev thaum ntsuas lub galvanometer scanner qhov ceev. Kev kub ceev galvanometer scanners tuaj yeem ncav cuag ntau qib ib ob rau kev ua cov khoom siv ceev ceev lossis cov ntawv thov siab, suav nrog PCB npav lossis laser engraving. Tsis tas li ntawd, xav txog lub sijhawm daws teeb meem ntawm lub system, uas cuam tshuam sai npaum li cas nws tuaj yeem txav tau thiab ruaj khov.
Qhov tseeb thiab Precision
Galvanometer laser scanners yuav tsum muaj tseeb thiab meej rau micro-machining thiab kev kho mob duab. Nrhiav cov tshuab nrog qis qis drift thiab hysteresis. Undoubtedly, cov qauv no lav lub scanner tsim cov txiaj ntsig kev ntseeg tau thoob plaws ntau qhov kev ua haujlwm rau cov ntawv thov raug-raws li.
Qhib-Loop lossis Kaw-Loop System
Cov txheej txheem tswj thiab tawm tswv yim txiav txim seb puas siv lub voj qhib lossis kaw-voj galvanometer laser scanner. Qhib-loop systems siv pre-set lub cev muaj zog yam ntxwv yam tsis muaj kev tawm tswv yim tiag tiag thiab pheej yig dua. Kaw-loop systems siv encoders lossis lwm yam sensors los them nyiaj rau qhov sib txawv ntawm daim iav. Nws yog qhov tsim nyog rau kev ua haujlwm siab ncaj ncees uas xav tau qhov tseeb ntawm txoj haujlwm.
Dynamic Performance
Hauv cov xwm txheej zoo, suav nrog kev hloov kho laser txiav lossis hloov cov khoom siv, galvanometer laser scanners yuav tsum nkag siab txog kev hloov pauv kev ua haujlwm. Cov neeg kho tshuab resonance zaus thiab damping piv tswj tau sai npaum li cas lub scanner tuaj yeem kho qhov nrawm lossis kev taw qhia yam tsis muaj oscillations. Tsis tas li ntawd, cov tshuab hluav taws xob xav tau thermal stability kom ua haujlwm zoo nyob rau hauv kev ua haujlwm siab thiab hloov cov xwm txheej ua haujlwm.
Field of View (FOV) thiab Chaw Ua Haujlwm
Qhov ntau ntawm galvanometer laser scanner tso siab rau nws FOV thiab chaw ua haujlwm. Cov ntawv thov kev lag luam, suav nrog kev ua textile thiab kev kos duab dav, tau txais txiaj ntsig los ntawm cov tshuab nrog FOV ntawm ntau pua square centimeters. Lub focal ntev ntawm lub optics yuav tsum tau xav txog. Ntev focal ntev muab FOV loj dua tab sis txo qis laser qhov chaw siv. Qhov ntawd cuam tshuam rau kev ua tau zoo thiab kev daws teeb meem. Yog li, qhov kev xaiv yuav tsum ua raws li daim ntawv thov qhov tseeb thiab qhov ntsuas.
