Lub tshuab hloov kho lub teeb ntawm qhov chaw txhais tau tias nyob rau hauv kev tswj hwm nquag, nws tuaj yeem hloov kho qee qhov kev teeb tsa ntawm lub teeb los ntawm cov kua siv lead ua kua, xws li hloov kho qhov loj ntawm lub teeb, hloov kho theem los ntawm qhov ntsuas refractive, hloov kho lub xeev polarization los ntawm kev tig ntawm lub dav hlau polarization, lossis paub txog qhov tsis sib xws - kev hloov pauv lub teeb sib xws, yog li sau qee cov ntaub ntawv rau hauv lub teeb nthwv dej, kom ua tiav lub hom phiaj ntawm lub teeb nthwv dej modulation. Nws tuaj yeem yooj yim thauj cov ntaub ntawv rau hauv ib lossis ob qhov ntev optical teb, thiab siv cov txiaj ntsig ntawm lub teeb dav dav, ntau-channel parallel processing thiab lwm yam kom ua tiav cov ntaub ntawv thauj khoom sai. Nws yog lub hauv paus tseem ceeb ntawm kev ua cov ntaub ntawv optical tiag tiag, kev sib txuas optical, kev suav optical thiab lwm yam systems.
Txoj cai ua haujlwm ntawm lub teeb pom kev zoo
Feem ntau hais lus, lub teeb modulator spatial muaj ntau lub units ywj pheej, uas tau teeb tsa hauv ib-seem lossis ob-seem array hauv qhov chaw. Txhua chav tsev tuaj yeem tau txais kev tswj hwm ntawm lub teeb pom kev zoo lossis lub teeb hluav taws xob ywj pheej, thiab hloov nws cov khoom siv optical raws li lub teeb liab, yog li ntawd modulate lub teeb nthwv dej ci ntsa iab rau nws. Cov khoom siv no tuaj yeem hloov qhov amplitude lossis intensity, theem, polarization xeev thiab wavelength ntawm optical faib hauv qhov chaw, lossis hloov lub teeb tsis sib xws mus rau hauv lub teeb sib xws nyob rau hauv kev tswj hwm ntawm hluav taws xob tsav lossis lwm yam teeb liab uas hloov pauv nrog lub sijhawm. Vim yog qhov khoom no, nws tuaj yeem siv ua chav tsev tsim kho lossis lub cuab yeej tseem ceeb hauv kev ua cov ntaub ntawv optical tiag tiag, kev suav optical thiab optical neural network systems.
Lub modulator teeb pom kev zoo spatial tuaj yeem muab faib ua hom kev xav thiab hom kev xa mus raws li hom kev nyeem teeb pom kev sib txawv. Raws li lub teeb liab tswj kev nkag, nws tuaj yeem muab faib ua optical addressing (OA-SLM) thiab electrical addressing (EA-SLM).
Daim ntawv thov ntawm lub teeb pom kev zoo spatial
Lub teeb siv lead ua kua siv lub teeb hloov pauv ncaj qha, ua haujlwm tau zoo, siv hluav taws xob tsawg, ceev ceev, zoo. Nws tuaj yeem siv dav hauv kev suav lej kho qhov muag, kev paub txog tus qauv, kev ua cov ntaub ntawv, kev tso saib thiab lwm yam, thiab muaj kev siv dav.
Lub tshuab hloov kho lub teeb pom kev zoo yog ib qho cuab yeej tseem ceeb hauv cov teb kho qhov muag niaj hnub xws li kev ua cov ntaub ntawv kho qhov muag tiag tiag, kev hloov kho qhov muag thiab kev suav kho qhov muag. Feem ntau, kev ua tau zoo ntawm lub teeb pom kev zoo txiav txim siab qhov txiaj ntsig thiab kev loj hlob ntawm cov teb no.
Cov ntawv thov tseem ceeb, kev thaij duab & kev kwv yees, kev faib cov nqaj hlau, kev ua kom cov nqaj hlau laser zoo nkauj, kev hloov kho wavefront sib xws, kev hloov kho theem, kev hloov kho qhov muag, kev tsim cov duab holographic, kev ua kom cov nqaj hlau laser zoo nkauj, thiab lwm yam.
