Kev ntsuas qhov tseeb ntawm lub zeem muag ntsuas lub tshuab yuav raug cuam tshuam los ntawm peb qhov xwm txheej, uas yog optical yuam kev, mechanical yuam kev thiab tib neeg kev ua haujlwm yuam kev.
Qhov kev ua yuam kev tsis zoo feem ntau tshwm sim hauv kev tsim khoom thiab sib dhos txheej txheem ntawm lub zeem muag ntsuas tshuab.Peb tuaj yeem txo qhov yuam kev no los ntawm kev txhim kho cov khoom sib dhos zoo thaum lub sijhawm tsim khoom.
Cov hauv qab no yog cov kev ceev faj kom tsis txhob muaj kev ua haujlwm tsis zoo:
1. Thaum txhim kho cov kev taw qhia kev tsheb nqaj hlau, nws lub hauv paus yuav tsum muaj theem txaus, thiab lub ntsuas ntsuas yuav tsum tau siv los kho nws cov qib raug.
2. Thaum txhim kho X thiab Y axis grating kav, lawv kuj yuav tsum tau khaws cia rau hauv lub xeev kab rov tav.
3. Lub worktable yuav tsum tau kho rau qib thiab verticality, tab sis qhov no yog ib qho kev sim ntawm tus kws tshaj lij lub peev xwm los ua ke.
Optical yuam kev yog qhov tsis sib haum xeeb thiab kev tsis sib haum xeeb uas tsim los ntawm txoj kev kho qhov muag thiab cov khoom siv thaum lub sij hawm kev yees duab, uas feem ntau yog ze rau cov txheej txheem tsim khoom ntawm lub koob yees duab.Piv txwv li, thaum lub teeb pom kev tshwm sim dhau los ntawm txhua lub lens, qhov yuam kev refraction thiab qhov yuam kev ntawm CCD lattice txoj hauj lwm yog tsim, yog li qhov kho qhov muag muaj qhov tsis sib xws ntawm geometric distortion, ua rau ntau hom geometric distortion ntawm lub hom phiaj duab taw tes thiab theoretical. duab taw tes.
Hauv qab no yog ib tug luv luv qhia txog ntau yam distortions:
1. Radial distortion: Nws feem ntau yog ib qho teeb meem ntawm symmetry ntawm lub ntsiab optical axis ntawm lub koob yees duab lens, uas yog, qhov tsis xws luag ntawm CCD thiab cov duab ntawm lub lens.
2. Eccentric distortion: Qhov laj thawj tseem ceeb yog qhov chaw kho qhov muag ntawm txhua lub lens tsis tuaj yeem nruj me ntsis collinear, uas ua rau cov chaw kho qhov muag tsis sib haum thiab cov chaw geometric ntawm qhov kho qhov muag.
3. Nyias prism distortion: Nws yog sib npaug rau ntxiv ib tug nyias prism rau qhov kho qhov muag system, uas yuav tsis tsuas ua rau radial sib txawv, tab sis kuj tangential deviation.Qhov no yog vim lub lens tsim, tsim khoom tsis xws luag, thiab machining installation yuam kev.
Qhov kawg yog tib neeg kev ua yuam kev, uas yog ze ze rau cov neeg siv kev ua haujlwm thiab feem ntau tshwm sim ntawm cov tshuab phau ntawv thiab cov tshuab semi-automatic.
Tib neeg yuam kev feem ntau suav nrog cov hauv qab no:
1. Tau qhov yuam kev ntawm lub ntsuas ntsuas (tsis ntse thiab burr npoo)
2. Qhov yuam kev ntawm Z-axis focal ntev hloov kho (qhov yuam kev ntawm qhov kev txiav txim siab pom tseeb tshaj plaws)
Tsis tas li ntawd, qhov tseeb ntawm lub zeem muag ntsuas lub tshuab kuj tseem cuam tshuam nrog nws qhov zaus ntawm kev siv, kev tu thiab kev siv ib puag ncig.Cov cuab yeej Precision xav tau kev saib xyuas tsis tu ncua, ua kom lub tshuab kom qhuav thiab huv si thaum tsis siv, thiab kom deb ntawm qhov chaw uas muaj kev vibration lossis nrov nrov thaum ua haujlwm.
