Lublub taub hau tsom xam sib sau ua ketuaj yeem muab faib ua lub taub hau vuam fais fab siab thiab nruab nrab qis raws li qhov xwm txheej ntawm daim ntawv thov, nrog rau qhov sib txawv tseem ceeb yog cov khoom siv lens thiab txheej. Cov xwm txheej uas tau pom yog qhov kub thiab txias hloov pauv (qhov kub thiab txias siab hloov pauv) thiab poob hluav taws xob. Lub taub hau collimating thiab focusing nrog feem ntau qhov kub thiab txias hloov pauv zoo tuaj yeem tswj tau hauv 1 hli; Yuav luag tshaj 2 hli; Kev poob hluav taws xob feem ntau yog hais txog kev poob hluav taws xob los ntawm lub laser nkag mus rau hauv lub taub hau vuam los ntawm lub taub hau QBH thiab tom qab ntawd tiv thaiv lub lens los ntawm hauv qab. Lub zog tseem ceeb yog hloov mus rau hauv lub lens cua sov, uas feem ntau xav tau tsawg dua 3%, qee qhov tuaj yeem ncav cuag 1%, thiab qee qhov tuaj yeem tshaj 5%. Yog li ntawd, ob qho no yog cov cim tseem ceeb rau kev sib sau ua ke thiab tsom mus rau lub taub hau. Nws yog qhov zoo tshaj plaws los ntsuas lawv koj tus kheej ua ntej siv lossis thov kom tus neeg tsim khoom muab cov ntawv ceeb toom cuam tshuam kom ntseeg tau tias cov khoom ua tau raws li qhov xav tau ntawm kev tsim khoom lag luam ntawm qhov chaw.
Kev faib tawm ntawm cov taub hau tsom sib koom ua ke - kev faib tawm ua haujlwm
Raws li seb nws puas muaj kev ua haujlwm viav vias thiab seb nws yog ib daim iav lossis ob daim iav, nws tuaj yeem muab faib ua lub taub hau sib dhos thiab tsom mus rau ib txwm muaj, lub taub hau pendulum ib leeg, thiab lub taub hau pendulum ob leeg. Nws feem ntau tsom mus rau ntau qhov xwm txheej xav tau, thiab txoj kev taug kev ntawm ob lub pendulum yuav nyuaj dua li ntawm ib lub pendulum.
Raws li qhov sib txawvlub tshuab laser, nws muaj peev xwm muab faib ua: (1) dual band composite taub hau (liab xiav, fiber semiconductor, thiab lwm yam), (2) composite swing taub hau (ib qho swing), thiab point loop taub hau.
(3)Lub taub hau vuam ntiv nplhaib yog ib hom taub hau vuam tshiab uas tuaj yeem ua cov teeb laser muaj zog siab rau hauv cov duab voj voog lossis cov duab ntiv nplhaib los ntawm kev ua kom lub zog faib tawm sib npaug. Nws zoo li tig cov laser muaj zog siab rau hauv cov teeb pom kev zoo, tab sis nws txawv. Piv rau cov duab voj voog, lub zog nruab nrab ntawm cov taub hau ntiv nplhaib tsis txaus thiab lawv lub peev xwm nkag mus tau tsawg. Txawm li cas los xij, txoj hauv kev yooj yim no ntawm kev ua tiav kev faib tawm lub zog laser zoo ib yam li cov teeb pom kev zoo voj voog los ntawm cov taub hau ntiv nplhaib tuaj yeem ua tiav tus nqi qis thiab qis splashing effect. Hauv kev vuam hlau, nws muaj qhov zoo tshwj xeeb ntawm roj. Vim yog qhov loj ntawm cov teeb pom kev zoo thiab qhov sib xws ntawm lub zog ceev, nws yuav yooj yim rau kev vuam cuav ntawm cov ntaub ntawv siab (txhuas, tooj liab).
Lub lens tsom xam sib dhos
Rau cov iav siv hauv cov tshuab xa xov laser, lawv cov ntaub ntawv tuaj yeem muab faib ua ob hom: cov ntaub ntawv xa mus thiab cov ntaub ntawv cuam tshuam; Lub iav tsom iav thiab lub iav tiv thaiv yuav tsum ua los ntawm cov ntaub ntawv xa mus. Cov kev cai: cov ntaub ntawv yuav tsum muaj kev xa mus zoo rau cov nthwv dej ua haujlwm, kub ua haujlwm siab thiab coefficient nthuav dav thermal qis. Feem ntau, lub iav tsom iav yuav tsum ua los ntawm fused silica; Lub iav tiv thaiv yog ua los ntawm cov ntaub ntawv cuam tshuam, feem ntau yog K9 iav. Cov khoom siv cuam tshuam yog ua los ntawm kev txheej ib zaj duab xis nyias ntawm cov khoom siv hlau cuam tshuam siab rau ntawm cov iav ci lossis cov hlau nto, thiab kev cuam tshuam tsis muaj kev tawg. Yog li ntawd, tsuas yog qhov tshwj xeeb ntawm cov ntaub ntawv cuam tshuam yog lawv qhov kev cuam tshuam ntawm ntau yam xim ntawm lub teeb. Cov khoom siv txheej txheem rau cov iav kho qhov muag yog: 1. Kev cuam tshuam ruaj khov ntawm lub teeb; 2. Kev ua haujlwm thermal siab; 3. Lub ntsiab lus yaj siab; Ua li no, txawm tias muaj av ntawm txheej txheej, kev nqus cua sov ntau dhau yuav tsis ua rau tawg lossis hlawv.
Qhov kev sib xyaw ua ke ntawm collimation thiab kev tsom xam feem ntau cuam tshuam rau qhov loj ntawm qhov chaw: Qhov loj ntawm qhov chaw ntawm lub teeb laser yog ib qho tseem ceeb uas cuam tshuam rau qhov zoo ntawm kev luam theej duab vuam, tshwj xeeb tshaj yog qhov loj ntawm qhov chaw tsom mus rau ntawm qhov chaw ntawm qhov workpiece ncaj qha cuam tshuam rau lub zog ceev ntawm lub teeb laser. Thaum lub zog laser luam theej duab yog tas li, qhov me me ntawm qhov chaw tuaj yeem ua tiav qhov ceev zog siab dua, uas yog qhov zoo rau kev vuam qhov chaw yaj siab thiab nyuaj rau yaj cov hlau. Tib lub sijhawm, nws tuaj yeem tau txais qhov sib piv loj dua thiab ua tau raws li qee qhov kev xav tau vuam tshwj xeeb. Thaum qhov chaw yaj ntawm cov khoom siv vuam qis, lossis thaum muaj qee qhov sib txawv ntawm ob lub phaj thaum lub sijhawm vuam, qhov loj ntawm qhov chaw feem ntau raug xaiv los ua tiav cov txiaj ntsig vuam zoo dua.
Qhov ntev ntawm qhov sib txuas ntawm lub teeb feem ntau yog nruab nrab ntawm 80-150 hli, thiab qhov ntev ntawm qhov sib txuas ntawm lub teeb feem ntau yog nruab nrab ntawm 100-300 hli; Nws feem ntau nyob ntawm qhov deb ntawm kev ua haujlwm thiab qhov loj ntawm qhov chaw (lub zog ceev), nrog rau qhov kam rau ntawm qhov chaw rau qhov sib txawv ntawm qhov sib txuas (yog tias qhov chaw me dhau, qhov sib txawv yuav xau lub teeb yog tias nws loj dhau, thiab qhov sib txawv feem ntau tsis loj dua 30% ntawm qhov chaw txoj kab uas hla).
Kev sim ua ntej siv ntawm lub taub hau tsom mus rau collimating: kev sim transmittance; Kev sim kub drift
