The Features
Iyo f-theta inotarisisa girazi remunda, chokwadi, imhando yegirazi remumunda, rakagadzirirwa kuita urefu hwemufananidzo uye scanning angle kugutsa hukama y=f*θ lens boka (θ ndiyo kona yekutsauka kwegalvanometer) , saka girazi re f-theta rinozivikanwawo selinear lens.Iine zvinhu zvakawanda:
(1) Pachiedza chemonochromatic, ndege yekufungidzira yendege, iyo yose yemufananidzo ndege yemhando yemhando inowirirana, iyo aberration idiki.
(2) Kumwe kutsauswa kumhanya kwechiedza chechiitiko kunofanana nekumhanya kusinga peri, saka kutarisisa kwemutsara kunogona kuwanikwa nechiedza chechiitiko cheakaenzana angular velocity.
Kuziva kweF-Theta Kutarisa Munda Mirror Sarudzo
Iwo makuru tekinoroji maparamendi emagirazi emunda anosanganisira kushanda wavelength, scanning range (kana kutarisisa kureba), uye yakanangwa nzvimbo dhayamita.
1) Kushanda Wavelength:Iyo yekushanda yavelength yemunda lens inotarirwa nelaser yemuchina wekumaka.Iyo yavelength yefiber laser ndeye 1064 nm, iyo wavelength yeCO2 laser ndeye 10.6 um, iyo yavelength yegirinhi laser i532 nm, iyo yavelength ye UV laser 355 nm, uye inoenderana munda lens inosarudzirwa inoenderana. laser.
2) Nzvimbo yekuongorora:Focused field girazi scanning area inotarwa nehurefu hwakatarisana negirazi remunda rakatariswa, kureba kwegirazi remunda kunowanzo ratidzwa paurefu hwekutarisa, kureba kwekutarisa uye nzvimbo yekuongorora ine empirical formula: nzvimbo f = 0.7 × yakatarisana kureba. .
Semuenzaniso, f = 160 mm girazi remunda rinoenderana ne 112 mm square, kururamisa kwese kwehupamhi hwenhamba ndeye 110 mm × 110 mm, f = 100 mm girazi remunda rinoenderana nehupamhi hwe 70 mm × 70 mm.
3)Mudzidzi wechiitiko:Chiitiko mudzidzi wegirazi remumunda anofanira kunge akaenzana nedhayamita yegomba relaser rinobva kugalvanometer.Asi tinoziva sei saizi yedhayamita yegomba relaser rinobva kugalvanometer?Tora diki pane mbiri nhamba: imwe = inobuda nzvimbo yelaser * iyo inowedzeredza yedanda rinowedzera;imwe yacho yakaenzana nenhamba yenzvimbo yegalvanometer.
Chii chinoitika kana dhayamita yelaser beam ichibva kugalvanometer yakakura kupfuura chiitiko chemudzidzi wegirazi remunda?Paunenge uchitamba iyi lenzi yemunda weiyo yakakura fomati yepateni, chikamu chepakati hachina dambudziko, mupendero wechikamu unonzwa sezviri pachena mwenje usina simba, kudzika kwekumaka kuchave zvakare kushoma.Iyi parameter yakawanda yemidziyo vatengesi havatarise, asiwo vanowanzoita zvikanganiso, vanofanira kungwarira.
4) Kutarisa dhayamita yenzvimbo "d":neyakapfava yekutarisisa nzira yenzvimbo "d" = 2fλ / D ziva, kureba kwakareba "f", ndiko kukura kwedhayamu renzvimbo "d";wavelength “λ” kureba, ndiko kukura kwedhayamita rinotarisa “d”;iyo yakakura dhayamita yenzvimbo yechiitiko D, idiki dhayamita yenzvimbo inotarisisa "d".
Asi tinoziva sei kuti inzvimbo yakawanda sei iyo girazi remunda rinotarisa?Pane parameter mukati me general field lens parameters: muganho we diffraction spot kana kunzi diffuse spot kana kunzi diki diki, kukosha uku kunenge kwakaenzana nehushoma kukosha kwemunda lens inogona kutarisa, asi kukosha uku ndiko kukosha kwedzidziso, ukoshi chaihwo kazhinji hombe kupfuura kukosha uku.
5) Chinhambwe chekushanda:Vatengi vazhinji vanotenga malenzi emunda uye vanocherechedza kureba kwekutarisa, asi iyo parameter yenzvimbo yekushanda haiwanzo kucherechedzwa.Asi kana uchitenga iyo yakareba yakatarisa kureba kwemunda lens, iyi parameter inofanirwa kutariswa zvakanyanya, zvikasadaro zviri nyore kukanganisa.Nekuti vatengi vazhinji vekhabhineti inosimudza mbiru yekugadzirisa kureba ishoma.Mukuwedzera, kana tichifunga nezvekukwirira kwekoramu, tinofanirawo kufunga nezvehurefu hwechigadzirwa pachayo, kureba kwechigadzirwa chacho pachayo 200mm yakakwirira, ipapo kureba kwekoramu inoenderana inofanira kuwedzerwa kune kukwirira kwechigadzirwa.
6) Kune imwe nzvimbo yakakomberedzwa kana yakakwira uye yakaderera kutenderedzwa kwechigadzirwa, kuwedzera chiratidzo chekumaka, yaona kudzika kwekutarisa kuzadzisa zvinodiwa.Sezvatinoziva, kurova chigadzirwa neimwe nzvimbo yakakombama kana yakakwira uye yakaderera kumusoro nekudzika, iyo munda lenzi inoda kuve nehumwe hudzamu hwekutarisa, uye kana ichida kuve nehurefu hurefu hwekutarisa, ipapo hurefu hwakatarisana hunoenderana. inoda kureba.Saka nguva ino yekutarisa girazi remunda haigone kungotarisa pahupamhi, asiwo kutora kudzika kwekutarisa mu account, saka iwe unofanirwa kuwedzera hupamhi, saka iyo focal urefu hunowedzera, kudzika kunowirirana kwekutarisa kuchawedzerawo.
7) Threads for Field Mirrors.Mamwe mabhureki ane shinda dzakasiyana dzegirazi remumunda.Saka kana iwe uchitenga girazi remumunda, iwe unofanirwawo kuona shinda, kana iwe usingakwanise kuwana shinda inoenderana yegirazi remunda, unogona kuwana girazi remunda kuti uite laser yekumaka muchina kabhineti kuita ring yekushandura shinda.
8) Zvimwe zvezvipimo zvakasara zvingave zvakakoshawo kuziva: M1 uye M2 maitiro (kure kwe galvanometer lens kubva kumunda lens), scanning angle θ, saizi ye lens, retroreflective point (izvi zvakakosha kune yakakwirira simba masisitimu) , asi maparamendi aya ane hany'a, uye vatengi vakasarudzika vanogona kukumbira izvi.
