Cov ntawv thov tshiab hauv optics coj los ntawm optical modulators

Lub hauv paus ntsiab lus ntawmkev hloov kho qhov muagtsis nyuaj. Nws feem ntau ua tiav qhov kev hloov kho ntawm qhov loj me, theem, polarization, refractive index, absorption rate thiab lwm yam ntxwv ntawm lub teeb los ntawm sab nraud stimuli, kom tswj tau qhov teeb liab optical, xws li ua kom cov photons nqa thiab xa cov ntaub ntawv. Cov khoom tseem ceeb ntawm ib qhoelectro-optic modulatormuaj peb ntu: cov siv lead ua los ntawm cov hluav taws xob, cov electrodes, thiab cov khoom siv kho qhov muag. Thaum lub sijhawm ua haujlwm ntawm kev hloov kho lub teeb, cov khoom siv hauv lub tshuab hloov kho qhov muag hloov nws cov ntsuas refractive, tus nqi nqus thiab lwm yam khoom nyob rau hauv kev cuam tshuam ntawm cov khoom siv sab nraud (xws li cov teb hluav taws xob, cov teb suab, kev hloov pauv thermal lossis cov zog kho tshuab), yog li cuam tshuam rau tus cwj pwm ntawm cov photons thaum lawv dhau los ntawm cov khoom siv, xws li kev tswj cov yam ntxwv ntawm lub teeb (amplitude, theem, polarization, thiab lwm yam). Lub siv lead ua los ntawm cov hluav taws xob yog lub hauv paus ntawmcov khoom siv kho qhov muag, lub luag haujlwm teb rau kev hloov pauv hauv lub zog hluav taws xob thiab hloov nws cov ntsuas refractive. Cov electrodes siv los siv cov zog hluav taws xob, thaum cov khoom siv kho qhov muag xws li polarizers thiab waveplates siv los coj thiab tshuaj xyuas cov photons hla dhau lub siv lead ua.

Cov Ntawv Thov Frontier hauv Optics

1. Kev tsim cov duab Holographic thiab cov thev naus laus zis tso tawm

Hauv kev tsim holographic, kev siv cov khoom siv kho qhov muag spatial optical modulators los kho cov teeb pom kev zoo tuaj yeem ua rau cov teeb pom kev cuam tshuam thiab diffract hauv ib txoj kev tshwj xeeb, tsim cov teeb pom kev sib txawv. Piv txwv li, SLM raws li cov kua siv lead ua kua lossis DMD tuaj yeem hloov kho qhov kev teb optical ntawm txhua pixel, hloov cov ntsiab lus ntawm daim duab lossis qhov pom hauv lub sijhawm tiag tiag, tso cai rau cov neeg saib pom cov nyhuv peb-seem ntawm daim duab los ntawm ntau lub kaum sab xis.

2. Kev khaws cov ntaub ntawv optical

Cov thev naus laus zis khaws cov ntaub ntawv optical siv cov yam ntxwv siab thiab lub zog siab ntawm lub teeb los encode thiab decode cov ntaub ntawv los ntawm kev hloov kho lub teeb kom meej. Cov thev naus laus zis no vam khom kev tswj hwm ntawm cov nthwv dej teeb, suav nrog kev hloov kho ntawm qhov loj me, theem thiab lub xeev polarization, los khaws cov ntaub ntawv ntawm cov xov xwm xws li cov discs optical lossis cov ntaub ntawv khaws cia holographic. Cov modulators optical, tshwj xeeb tshaj yog spatial optical modulators, ua lub luag haujlwm tseem ceeb hauv kev tso cai rau kev tswj hwm optical meej heev ntawm cov txheej txheem khaws cia thiab nyeem ntawv.

Ntawm theem kho qhov muag, cov photons zoo li cov neeg seev cev zoo nkauj, seev cev zoo nkauj rau "suab paj nruag" ntawm cov ntaub ntawv xws li siv lead ua, siv lead ua kua thiab cov fibers kho qhov muag. Lawv tuaj yeem hloov pauv kev coj ua, ceev, thiab txawm tias hnav "ris tsho xim sib txawv" tam sim ntawd, hloov pauv lawv cov kev txav mus los thiab rhythms, thiab nthuav qhia ib qho kev ua yeeb yam zoo kawg nkaus tom qab lwm qhov. Qhov kev tswj hwm meej ntawm cov photons no yog qhov tseem ceeb rau kev txiav txim siab ntawm cov thev naus laus zis kho qhov muag yav tom ntej, ua rau lub ntiaj teb kho qhov muag puv nrog ntau yam tsis kawg.
