F-theta yibanda kumirorerwamo, mubyukuri, ni ubwoko bwindorerwamo yumurima, yashizweho kugirango ishusho yuburebure hamwe na scan ya angle kugirango ihuze umubano y = f * θ lens group (θ ni inguni yo gutandukana kwa galvanometero) , indorerwamo ya f-theta nayo izwi nkumurongo ugizwe.Ifite ibintu byinshi:

Ubumenyi bwa F-Theta Yibanze Kumurima Indorerwamo
Ibyingenzi bya tekinike yibiranga indorerwamo zirimo uburebure bwumurongo, gukora scaneri (cyangwa uburebure bwibanze), hamwe na diameter yibibanza.
1) Uburebure bw'akazi:Uburebure bwumurongo wumurongo wumurongo ugenwa na laser yimashini iranga.Uburebure bwa fibre laser ni 1064 nm, uburebure bwa lazeri ya CO2 ni 10,6 um, uburebure bwumurambararo wicyatsi kibisi ni 532 nm, uburebure bwumurambararo wa UV ni 355 nm, kandi hatoranijwe lens yumurima uhuye kugirango uhure laser.
2) Ahantu ho gusikana:Agace kerekanwe kumurongo indorerwamo yogusuzuma kugenwa nuburebure bwibanze bwindorerwamo yibirindiro, uburebure bwibanze bwindorerwamo yumurima mubusanzwe burangwa gusa kuburebure bwerekanwe, uburebure bwerekanwe hamwe na scanning ifite formulaire ifatika: agace f = 0.7 × uburebure bwibanze .
Kurugero, f = 160 mm indorerwamo yumurima ihuye na kare ya mm 112, gukosora muri rusange ubugari bwumubare ni 110 mm × 110 mm, indorerwamo ya f = 100 mm ihuye nubugari bwa mm 70 × 70 mm.
3)Umunyeshuri wabaye:Umunyeshuri wabaye indorerwamo yumurima agomba kuba angana na diameter yumurambararo wa laser uva muri galvanometero.Ariko twabwirwa n'iki ubunini bwa diameter ya laser beam iva muri galvanometero?Fata ntoya mu mibare ibiri: imwe = ikibanza gisohoka cya laser * kugwiza kwagura urumuri;ikindi gihwanye numubare wikibanza cya galvanometero.
Bigenda bite iyo diameter yumurambararo wa laser iva muri galvanometero nini kuruta umunyeshuri wabaye indorerwamo?Mugihe ukina iyi lens ya lens yuburyo bunini bwubushushanyo, igice cyo hagati ntakibazo, inkombe yikigice izumva bigaragara ko urumuri rudakomeye cyane, ikimenyetso cyimbitse nacyo kizaba gito.Iyi parameter nibikoresho byinshi abadandaza ntibitondera, ariko kandi akenshi bakora amakosa, bagomba kwitonda.
4) Kwibanda kuri diameter "d":nuburyo bworoshye bwo kwibanda kumurongo "d" = 2fλ / D menya, uburebure burebure "f", nini nini yibanda kuri diameter "d";uburebure bwumurongo “λ” muremure, nini nini yibanda kuri diameter “d”;nini ya diameter yikibanza cyabereye D, ntoya yibanda kuri diameter "d".
Ariko twabwirwa n'iki ko indorerwamo yihariye yibanda?Hano hari ibipimo imbere murwego rusange rwibipimo byerekana: imipaka yikibanza cyangwa bita diffuse ikibanza cyangwa bita umwanya muto, iyi gaciro iringaniza cyane cyane nagaciro gake kumurima lens irashobora kwibandaho, ariko ako gaciro nigiciro cyiza, agaciro nyako muri rusange ni kinini kurenza agaciro.
5) Intera y'akazi:Abakiriya benshi bagura lensike yumurima kandi bakareba uburebure bwibanze, ariko ibipimo byintera yakazi ntibikunze kugaragara.Ariko mugihe uguze uburebure burebure bwumurima, iyi parameter igomba kwitabwaho byumwihariko, bitabaye ibyo gukora amakosa.Kuberako abakiriya benshi ba guverinoma bazamura inkingi yo kugenzura uburebure bugarukira.Mubyongeyeho, mugihe dusuzumye uburebure bwinkingi, dukeneye no gutekereza ku burebure bwibicuruzwa ubwabyo, uburebure bwibicuruzwa ubwabwo ni 200mm z'uburebure, noneho uburebure bwinkingi ijyanye bugomba kongerwaho uburebure bwibicuruzwa.
6) Hariho ubuso bunini bugoramye cyangwa hejuru kandi ntoya hejuru yibicuruzwa, kugirango wongere ubugari bwikimenyetso, wabonye ubujyakuzimu bwibanze kugirango uhuze ibisabwa.Nkuko tubizi, gukubita ibicuruzwa hamwe nubuso bunini bugoramye cyangwa hejuru kandi hasi hejuru no hasi, lens yumurima igomba kuba ifite ubujyakuzimu bwibanze, kandi niba ikeneye kugira uburebure burebure bwibanze, hanyuma uburebure bujyanye nuburebure. igomba kuba ndende.Iki gihe rero kugirango dusuzume indorerwamo yumurima ntishobora kureba gusa ubugari, ariko kandi no gufata ubujyakuzimu bwibandwaho, bityo rero ugomba kongera ubugari, bityo uburebure bwibanze bukiyongera, ubujyakuzimu bujyanye nibitekerezo nabyo biziyongera.
7) Imitwe yindorerwamo.Ibiranga bimwe bifite imirongo itandukanye yindorerwamo.Iyo rero uguze indorerwamo yumurima, ugomba no kumenya urudodo, niba mubyukuri udashobora kubona urudodo ruhuye rwindorerwamo yumurima, urashobora kubona indorerwamo yumurima kugirango ukore imashini yerekana imashini ya laser kugirango ukore impeta yo guhindura.
8) Bimwe mubintu bisigaye bishobora nanone kuba ingenzi kumenya: indangagaciro za M1 na M2 (intera ya lens ya galvanometero kuva kumurongo wumurima), gusikana inguni θ, ingano yinzira, ingingo isubira inyuma (ibi nibyingenzi kuri sisitemu yo hejuru) , ariko ibyo bipimo ni bike cyane, kandi abakiriya badasanzwe barashobora kubisaba.
