Lub "Optical Art" coj los ntawmcov khoom siv kho qhov muag

Nrog rau kev txhim kho ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, cov khoom siv kho qhov muag kuj tseem yuav ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw xws li holographic projection thiab display, optical data storage, optical communication, computational imaging thiab machine vision.

Cov Ntawv Thov Frontier hauv Optics

1. Kev sib txuas lus optical

Nrog rau kev txhim kho ntawm thev naus laus zis sib txuas lus, kev hloov kho qhov muag tau dhau los ua lub hauv paus ntawm cov txheej txheem sib txuas lus kho qhov muag niaj hnub, thiab nws txoj kev loj hlob cuam tshuam ncaj qha rau qhov ceev thiab bandwidth ntawm kev xa cov ntaub ntawv. Nrog rau kev tso tawm ntawm 5G thiab yav tom ntej 6G tes hauj lwm, qhov kev thov rau kev xa cov ntaub ntawv ceev ceev thiab muaj peev xwm loj zuj zus txhua hnub. Kev nce qib ntawmkev hloov kho qhov muagthev naus laus zis yuav txhawb nqa kev loj hlob ntawm cov thev naus laus zis. Ua tsaug rau lub zog siab thiab cov yam ntxwv siab ntawm photons, kev siv tshuab kho qhov muag ua lub luag haujlwm tseem ceeb hauv kev lag luamkev sib txuas lus pom kevLos ntawm kev tswj hwm qhov theem, qhov loj me lossis lub xeev polarization ntawm lub teeb, cov khoom siv kho qhov muag tuaj yeem encode cov teeb liab kom ua tiav kev xa cov ntaub ntawv ceev thiab bandwidth siab. Thaum lub teeb nthwv dej hla dhautus neeg hloov kho, lub modulator hloov pauv cov yam ntxwv ntawm lub teeb nthwv dej raws li cov ntaub ntawv xa mus. Qhov kev hloov kho kom meej no ua rau ntau lub teeb liab xa mus tib lub sijhawm hauv tib lub fiber ntau, ua rau muaj peev xwm nqa cov ntaub ntawv thiab kev ua haujlwm ntawm lub kaw lus sib txuas lus zoo heev.

2. Kev suav duab thiab kev pom ntawm lub tshuab

Kev siv cov thev naus laus zis optical modulation hauv kev suav duab thiab kev pom ntawm lub tshuab tau hloov pauv txoj kev tau txais thiab tshuaj xyuas cov duab. Cov thev naus laus zis no txhim kho qhov zoo thiab cov ntsiab lus ntawm cov duab los ntawm kev tswj hwm qhov theem, qhov loj me lossis lub xeev polarization ntawm lub teeb, yog li ua tiav kev vam meej hauv ntau yam lag luam. Computational imaging yog ib qho thev naus laus zis uas sib xyaw ua ke tsim kho qhov muag thiab cov txheej txheem ua tiav tom qab duab los txhim kho qhov zoo ntawm cov duab thiab daws cov teeb meem kev kos duab ib txwm muaj. Hauv cov txheej txheem no, cov khoom siv kho qhov muag xws li SLM thiab DMD ua lub luag haujlwm tseem ceeb. Lawv tuaj yeem hloov kho cov yam ntxwv ntawm cov nthwv dej teeb pom kev zoo, xws li ua tiav cov lej wavefront los ntawm kev hloov pauv qhov faib ntawm lub teeb, lossis kho qhov faib ntawm lub teeb kom ua tiav cov duab siab dynamic ntawm qhov chaw. Hauv cov tshuab pom kev, cov thev naus laus zis optical modulation siv los ua kom tiav qhov chaw ntes thiab paub cov khoom kom meej dua. Los ntawm kev siv lub teeb modulator los tswj lub teeb pom kev zoo, lub tshuab pom kev tuaj yeem rho tawm ntau cov ntaub ntawv xwm txheej hauv qab cov teeb pom kev zoo sib xws, txhim kho qhov sib piv thiab kev daws teeb meem ntawm daim duab.

Cov khoom siv kho qhov muag zoo li cov khawv koob uas nyob hauv tes ntawm cov kws ua khawv koob, tsis yog tsuas yog ua kom pom kev ua khawv koob zoo kawg nkaus hauv kev sib txuas lus niaj hnub no, kev suav duab thiab cov tshuab photoelectric, tab sis kuj qhib qhov rooj ntawm qhov tsis kawg rau yav tom ntej. Xav txog tias nws zoo li lub tuner meej, muaj peev xwm kho cov "sau ntawv" ntawm qubits, ua rau cov teebmeem quantum thiab cov xwm txheej kho qhov muag pom ntau dua cov suab paj nruag zoo nkauj. Nws kuj yog ib tug "kws ua khawv koob" ntawm microelectronics thiab nanotechnology, muaj peev xwm thawb tus nqi siv ntawm cov ntaub ntawv mus rau qhov kawg thiab ua rau cov txheej txheem tsim khoom zoo li cov khoom siv khawv koob tsis siv neeg. Nrog rau kev tshwm sim ntawm 5G thiab txawm tias 6G tes hauj lwm, cov thev naus laus zis kho qhov muag ua haujlwm zoo li tus neeg xa xov sai, ua tiav peb lub siab xav rau kev xa cov ntaub ntawv ceev ceev thiab muaj peev xwm loj. Txawm hais tias cov nqi siab, cov txheej txheem nyuaj thiab kev lag luam ib txwm muaj "cov neeg sib tw tsim" ntawm nws txoj kev loj hlob, los ntawm kev nce qib thev naus laus zis tas mus li thiab "kev sib koom tes" ntawm cov kev qhuab qhia, tag nrho cov teeb meem no yuav raug kov yeej ib qho los ntawm ib qho. Yav tom ntej, cov khoom siv kho qhov muag yuav dhau los ua lub cav ntawm kev hloov pauv thiab kev yooj yim, ua rau muaj kev hloov pauv tshiab los ntawm kev tshawb fawb txog kev kho mob, los ntawm kev tsim khoom lag luam mus rau kev tsim kho tshiab, thiab txawm tias nyob rau hauv cov teb ntawm cov ntaub ntawv thev naus laus zis thiab kev ruaj ntseg tub rog.
