Spatial lub teeb modulator txhais tau hais tias nyob rau hauv kev tswj hwm, nws tuaj yeem hloov kho qee qhov teeb meem ntawm lub teeb teb los ntawm cov kua siv lead ua kua molecules, xws li kev hloov pauv lub amplitude ntawm lub teeb teb, modulating theem los ntawm lub refractive index, modulating lub xeev polarization los ntawm kev sib hloov ntawm lub dav hlau polarization. , los yog realizing lub incoherent – coherent lub teeb hloov dua siab tshiab, thiaj li yuav sau tej yam ntaub ntawv mus rau hauv lub teeb yoj, kom ua tiav lub hom phiaj ntawm lub teeb yoj modulation. Nws tuaj yeem yooj yim thauj cov ntaub ntawv mus rau hauv ib lossis ob qhov chaw kho qhov muag, thiab siv qhov zoo ntawm qhov dav ntawm lub teeb, kev ua haujlwm ntau channel 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 kho qhov muag ntawm lub sijhawm, kev sib txuas kho qhov muag, kev siv kho qhov muag thiab lwm lub tshuab.
Kev khiav hauj lwm hauv paus ntsiab lus ntawm spatial light modulator
Feem ntau hais lus, spatial light modulator muaj ntau chav nyob ywj pheej, uas tau teem rau hauv ib qho los yog ob-dimensional array hauv qhov chaw. Txhua chav tuaj yeem tau txais kev tswj hwm ntawm cov teeb liab kho qhov muag lossis hluav taws xob teeb liab ntawm nws tus kheej, thiab hloov nws tus kheej kho qhov muag raws li lub teeb liab, thiaj li hloov kho lub teeb yoj illuminated rau nws. Cov khoom siv no tuaj yeem hloov pauv qhov amplitude lossis kev siv zog, theem, lub xeev polarization thiab wavelength ntawm optical faib nyob rau hauv qhov chaw, los yog hloov lub teeb incoherent mus rau lub teeb coherent nyob rau hauv kev tswj ntawm hluav taws xob tsav los yog lwm yam teeb liab uas hloov nrog lub sij hawm. Vim hais tias ntawm cov cuab yeej no, nws tuaj yeem siv los ua lub tsev tsim kho lossis cov cuab yeej tseem ceeb hauv kev ua cov ntaub ntawv kho qhov muag, kev suav kho qhov muag thiab kho qhov muag neural network systems.
Lub spatial light modulator tuaj yeem muab faib ua hom kev xav thiab kis tau tus mob raws li kev nyeem ntawv sib txawv ntawm lub teeb. Raws li cov tswv yim tswj lub teeb liab, nws tuaj yeem muab faib ua qhov chaw nyob (OA-SLM) thiab chaw nyob hluav taws xob (EA-SLM).
Daim ntawv thov ntawm spatial light modulator
Cov kua siv lead ua lub teeb valve siv lub teeb - lub teeb hloov pauv ncaj qha, kev ua haujlwm siab, kev siv hluav taws xob tsawg, ceev ceev, zoo zoo. Nws tuaj yeem siv dav hauv kev siv kho qhov muag, kev paub txog tus qauv, kev ua cov ntaub ntawv, tso saib thiab lwm yam kev lag luam, thiab muaj cov ntawv thov dav dav.
Spatial light modulator yog cov cuab yeej tseem ceeb hauv kev kho qhov muag niaj hnub xws li kev ua cov ntaub ntawv kho qhov muag, hloov kho qhov muag thiab kev suav kho qhov muag. Rau qhov loj, qhov kev ua tau zoo ntawm spatial light modulators txiav txim siab qhov txiaj ntsig thiab kev loj hlob ntawm cov teb no.
Daim ntawv thov tseem ceeb, duab & projection, beam splitting, laser beam shaping, coherent wavefront modulation, theem modulation, optical tweezers, holographic projection, laser pulse shaping, thiab lwm yam.
