Moderi yumucyo (SLM) mubyukuri nigikoresho cya optique gifite imbaraga zishobora gukwirakwizwa muburyo butandukanye bwa amplitude, icyiciro cyangwa polarisiyasi yumucyo wumucyo. Ibicuruzwa byacu byateje imbere SLM bifashisha ikoranabuhanga rya silikoni rishingiye ku buhanga bwa kirisiti kugira ngo igenzure imitunganyirize ya molekile ya kirisitu ikoresheje ibimenyetso by'amashanyarazi kugira ngo igere ku buryo bunoze bwo kugenzura imiraba y’umucyo. Ubu bushobozi bwo kugenzura neza butuma Moderi yumucyo (SLM) "canvas yubwenge" muri sisitemu ya optique. Irashoboye kubyara ubwoko butandukanye bwurumuri rugoye rwo gukwirakwiza muburyo bwiza.

Moderi yumucyo (SLM) nikintu gifite imbaraga za optique zishobora guhindura igihe nyacyo cyo guhinduranya urumuri rwa amplitude, icyiciro, hamwe na polarisiyasi igenzurwa hanze.

Amazi ya kirisiti yumucyo uhinduranya bigizwe ahanini na flux ya kirisiti yumucyo, ikibaho cyo gutwara hamwe na software igenzura. Ihame ryakazi ryayo rikoresha cyane cyane ifoto yumuriro wa kirisiti yamazi, iyobowe nikimenyetso cyo gutwara, impinduka ...

Umucyo uhinduranya urumuri ni ikintu gifite imbaraga zishobora guhindura amplitude, icyiciro na polarisiyasi yumucyo wibyabaye mugihe nyacyo iyobowe nibimenyetso byo hanze. Ikoreshwa ryumucyo utandukanya moderi mugutunganya laser irashobora kumenya imbaraga ...

Umucyo utanga urumuri ni igikoresho gikoresha ibikoresho byacyo kugirango uhindure amplitude, icyiciro nibindi bipimo byumucyo winjiza munsi yubugenzuzi bukora, kandi ubona urumuri ruteganijwe gukwirakwizwa kumurima wanyuma wakira ukoresheje igenzura ...

Gukwirakwiza neza ni ibintu bigaragara muri kamere, kandi gutatanya urumuri biterwa nuburyo bugoye hamwe na spatio-by'agateganyo inhomogeneité yinzira yo gukwirakwiza urumuri mubitangazamakuru,

Muri optique ya fibre itumanaho hamwe nibimenyetso bifatika byo kugenzura cyangwa guhindura amplitude, inshuro, icyiciro, polarisiyasi nibindi biranga ibipimo byabatwara ibintu byitwa optique modulation. Uruhare rwa optique ya modulike ni ukwemerera amakuru gukoresha ibiranga umucyo ubwayo kugirango ugere ku buryo bwihuse bwo gutunganya no kohereza, kandi birashobora guhagarika neza kwivanga kw’imashanyarazi yo hanze, kugirango ikwirakwizwa ryamakuru rihamye. Hamwe nogukoresha kwinshi kwikoranabuhanga ryogukwirakwiza ibice byinshi (DWDM) hamwe niterambere ryinshi ryubushobozi bwogukwirakwiza fibre optique, tekinoroji ya SDH imaze igihe kinini iremerewe, hashingiwe kumurongo wa gatatu woguhindura ibintu byinshi (WSS) nkigisekuru cya gatatu cyibikorwa byinshi byoguhindura optique yinjizwamo kandi igahuza ibikorwa byinshi mumashanyarazi ya optique hamwe nubushakashatsi bwihuse mubikorwa bya optique mumashanyarazi ya optique hamwe nubushakashatsi bwihuse mubikorwa bya optique mumashanyarazi vuba aha. iterambere.

Hamwe niterambere ryubucuruzi bwitumanaho rya terefone igendanwa, tekinoroji ya 6 yo gutumanaho igendanwa (6G) yahindutse ahantu h’ubushakashatsi. Umuyoboro w'itumanaho wa 6G ufite umuvuduko mwinshi wo gukwirakwiza, ubushobozi bunini bwumuyoboro, gutinda gukwirakwizwa guto, gukora neza cyane no kwizerwa gukomeye, nibindi byingenzi, 6G itahura isano nini yubwenge hagati yabantu nibintu, ni ukuvuga, "Byose bifitanye isano cyane!". Kugirango tumenye ibintu byinshi byiza biranga umuyoboro wa itumanaho wa 6G, nigute ushobora kumenya ibisekuruza byinshi hamwe na ultra-nini nini ya antenne array byahindutse ubushakashatsi.

Ibintu bya Vortex bigaragara mubuzima, nka vortices yo koga ibaho mugihe cyo kuvoma amazi, kubyuka vortice itandukana nubwato mugihe bagenda, tornado, tifuni, hamwe no kuzenguruka inyanja. Umucyo wa Vortex (utwara orbital angular momentum, OAM) wavumbuwe bwa mbere kandi ushyirwa mubikorwa cyane cyane mubijyanye na optique, ni ukuvuga kubyara fotone ya vortex na beam vortex, kandi igitekerezo cyibiti bya vortex cyatanzwe bwa mbere na Coullet nabandi. muri 1989. Mu 1922, L. Allen n'abandi. byerekanwe ko OAM ibaho mumirongo ya vortex, yasunikaga umurima kumwanya wambere kwisi.
