Kawmlasercov txheej txheem sib dhos
Ua kom ntseeg tau qhov kev sib tw ntawm lub teeb laser yog lub luag haujlwm tseem ceeb ntawm cov txheej txheem sib dhos. Qhov no yuav tsum tau siv cov optics ntxiv xws li lo ntsiab muag lossis fiber ntau collimators, tshwj xeeb tshaj yog rau diode lossisfiber ntau laser qhov chaw. Ua ntej laser kev sib raug zoo, koj yuav tsum paub txog cov txheej txheem kev nyab xeeb ntawm laser thiab xyuas kom meej tias koj tau nruab nrog cov tsom iav kev nyab xeeb tsim nyog rau thaiv cov laser wavelengths. Tsis tas li ntawd, rau cov lasers pom tsis pom, cov ntawv txheeb xyuas yuav xav tau los pab kev sib raug zoo.
Hauvlaser alignment, Lub kaum sab xis thiab txoj hauj lwm ntawm lub nqaj yuav tsum tau tswj ib txhij. Qhov no tuaj yeem xav tau kev siv ntau yam optics, ntxiv qhov nyuaj rau qhov chaw sib dhos, thiab tuaj yeem siv ntau qhov chaw desktop. Txawm li cas los xij, nrog kinematic mounts, ib qho kev daws teeb meem yooj yim thiab siv tau zoo, tshwj xeeb tshaj yog rau kev siv qhov chaw txwv.

Daim duab 1: Parallel (Z-fold) qauv

Daim duab 1 qhia txog kev teeb tsa yooj yim ntawm Z-Fold qauv thiab qhia tias yog vim li cas tom qab lub npe. Ob daim iav mounted ntawm ob lub kinematic mounts yog siv rau angular displacement thiab positioned kom qhov teeb meem teeb beam hits daim iav nto ntawm txhua daim iav ntawm tib lub kaum sab xis. Txhawm rau kom yooj yim rau kev teeb tsa, tso ob daim iav ntawm li 45 °. Hauv kev teeb tsa no, thawj qhov kev txhawb nqa kinematic yog siv kom tau txais qhov xav tau ntsug thiab kab rov tav txoj hauj lwm ntawm lub nqaj, thaum qhov kev txhawb nqa thib ob yog siv los them rau lub kaum sab xis. Tus qauv Z-Fold yog txoj kev nyiam rau aiming ntau lub teeb laser ntawm tib lub hom phiaj. Thaum sib txuas cov lasers nrog cov wavelengths sib txawv, ib lossis ntau daim iav yuav tsum tau hloov nrog cov lim dej dichroic.

Txhawm rau txo qhov duplication hauv cov txheej txheem sib dhos, lub laser tuaj yeem ua raws li ob lub ntsiab lus sib cais. Ib qho yooj yim crosshair lossis daim npav dawb cim nrog X yog cov cuab yeej siv tau zoo. Ua ntej, teeb tsa thawj qhov taw qhia ntawm lossis ze ntawm daim iav 2, ze rau lub hom phiaj li sai tau. Lub ntsiab lus thib ob ntawm kev siv yog lub hom phiaj nws tus kheej. Siv thawj kinematic sawv ntsug los kho cov kab rov tav (X) thiab ntsug (Y) txoj haujlwm ntawm lub nqaj ntawm qhov pib siv taw tes kom nws phim txoj haujlwm xav tau ntawm lub hom phiaj. Thaum txoj haujlwm no tau mus txog, ob lub kinematic bracket yog siv los kho lub angular offset, aiming lub laser beam ntawm lub hom phiaj tiag tiag. Thawj daim iav yog siv los kwv yees qhov xav tau kev sib tw, thaum daim iav thib ob yog siv los kho qhov kev sib tw ntawm qhov thib ob siv taw tes lossis lub hom phiaj.

daim duab 2: Vertical (Figure-4) qauv

Tus qauv-4 yog qhov nyuaj dua li Z-Fold, tab sis tuaj yeem muab cov txheej txheem kev sib cog lus ntau dua. Zoo ib yam li Z-Fold qauv, daim duab-4 layout siv ob daim iav mounted ntawm txav brackets. Txawm li cas los xij, tsis zoo li Z-Fold qauv, daim iav yog mounted ntawm 67.5 ° Lub kaum sab xis, uas ua rau "4" duab nrog lub laser beam (Daim duab 2). Qhov kev teeb tsa no tso cai rau lub teeb pom kev 2 tso tawm kom deb ntawm qhov chaw laser beam txoj kev. Raws li nrog Z-Fold configuration, lublaser nqajyuav tsum tau ua raws li ob lub ntsiab lus siv, thawj qhov taw qhia ntawm daim iav 2 thiab qhov thib ob ntawm lub hom phiaj. Thawj kinematic bracket yog siv los txav lub laser taw tes rau qhov xav tau XY txoj hauj lwm nyob rau saum npoo ntawm daim iav thib ob. Tom qab ntawd, ib qho kinematic bracket thib ob yuav tsum tau siv los them nyiaj rau kev hloov pauv ntawm lub kaum sab xis thiab kev sib raug zoo ntawm lub hom phiaj.

Txawm hais tias qhov twg ntawm ob qhov kev teeb tsa raug siv, ua raws li cov txheej txheem saum toj no yuav tsum txo qis tus naj npawb ntawm iterations xav tau kom ua tiav qhov xav tau. Nrog rau cov cuab yeej zoo thiab cov cuab yeej siv thiab ob peb lub tswv yim yooj yim, laser kev sib raug zoo tuaj yeem ua kom yooj yim heev.
