mayankho a standard intensity modulator

Modulator ya mphamvu

Monga modulator yomwe imagwiritsidwa ntchito kwambiri m'machitidwe osiyanasiyana a kuwala, kusiyanasiyana kwake ndi magwiridwe ake zitha kufotokozedwa ngati zambiri komanso zovuta. Lero, ndakukonzerani mayankho anayi a standard intensity modulator: mayankho amakina, mayankho a electro-optical, dongosolo la Acousto-optic, ndi dongosolo la liquid crystal.

Yankho la Makina

Makina owongolera mphamvu zamagetsi ndiye makina owongolera mphamvu zamagetsi oyamba komanso ogwiritsidwa ntchito kwambiri. Mfundo yake ndikusintha chiŵerengero cha kuwala kwa s kupita ku vuto mu kuwala kozungulira pozungulira mbale ya theka la mafunde ndikugawa kuwala kudzera mu chowunikira. Kuyambira kusintha koyamba kwamanja mpaka makina odziyimira pawokha komanso olondola kwambiri masiku ano, mitundu yazinthu zake ndi chitukuko cha mapulogalamu ake zakhwima. Fortune Technology imapatsa makasitomala mndandanda wamagetsi kapena zowongolera zamanja ndikuthandizira zinthu zozungulira ndi zinthu zina zokhudzana nazo kuti zigwirizane ndi ntchito zosiyanasiyana. Zofunikira pa kapangidwe:

yankho lamagetsi ndi kuwala

Chosinthira mphamvu yamagetsi ndi kuwala kwa kuwala (electro-optical intensity modulator) chingasinthe mphamvu kapena kukula kwa kuwala kwa polarized. Mfundoyi imachokera pa mphamvu ya Pockels ya electro-optical crystal. Pambuyo poti kuwala kwa polarized kudutsa mu electro-optic crystal yomwe imagwiritsidwa ntchito ndi magetsi, mkhalidwe wa polarization umasinthidwa ndikugawidwa mosankha ndi chowunikira. Mphamvu ya kuwala komwe kumatulutsidwa imatha kulamulidwa mwa kusintha mphamvu ya magetsi, ndipo kukwera/kutsika kwa dongosolo la ns kumatha kuchitika. Podalira zaka zake zabwino m'munda wa ma electro-optic crystals, Fortune Technology yayambitsa mndandanda wa ma modulators amagetsi monga ma shutter othamanga kwambiri, kupatsa makasitomala mayankho okhwima komanso osinthika.

Pulojekiti ya Phokoso ndi Kuwala

Chosinthira cha acousto-optic chingagwiritsidwenso ntchito ngati chosinthira mphamvu. Kusintha mphamvu ya diffraction kumatha kulamulira mphamvu ya kuwala kwa 0th order ndi kuwala kwa 1st order kuti akwaniritse cholinga chosintha mphamvu ya kuwala. Chipata chagolide cha Acousto-optic (optical attenuator) chili ndi mawonekedwe a liwiro la modulation mwachangu komanso malire owononga kwambiri. Fortune Technology ikhoza kupereka ma modulators a acousto-optic intensity okhala ndi malire owononga opitilira 1GW/cm2 komanso kufalikira kochepa. Itha kupatsa makasitomala kapangidwe kabwino kwambiri ka yankho malinga ndi liwiro la modulation, kutalika kwa mafunde, m'mimba mwake, chiŵerengero cha kutha, ndi zizindikiro zina zomwe kasitomala amafunikira.

Yankho la LCD

Zipangizo zamakristalo amadzimadzi nthawi zambiri zimagwiritsidwa ntchito ngati mbale zosinthira mafunde kapena zosefera zosinthika. Kuwonjezera zinthu zinazake zozungulira kumapeto awiri a selo lamadzimadzi la kristalo komwe magetsi oyendetsera magetsi amagwiritsidwa ntchito kungapangidwe kukhala chotseka chamadzimadzi cha kristalo kapena chosinthira mafunde. Chogulitsachi chili ndi malo otseguka bwino—zinthu monga zazikulu komanso zodalirika kwambiri.

Kampani ya Beijing Rofea Optoelectronics Co., Ltd. yomwe ili ku "Silicon Valley" ku China - Beijing Zhongguancun, ndi kampani yapamwamba kwambiri yodzipereka kutumikira mabungwe ofufuza am'deralo ndi akunja, mabungwe ofufuza, mayunivesite ndi ogwira ntchito zofufuza zasayansi zamabizinesi. Kampani yathu imagwira ntchito yofufuza ndi kupanga zinthu za optoelectronic payokha, kupanga, kupanga, kugulitsa zinthu za optoelectronic, ndipo imapereka mayankho atsopano komanso ntchito zaukadaulo kwa ofufuza asayansi ndi mainjiniya amafakitale. Pambuyo pa zaka zambiri zopanga zinthu zatsopano payokha, yapanga mndandanda wolemera komanso wangwiro wa zinthu zamagetsi, zomwe zimagwiritsidwa ntchito kwambiri m'maboma, m'magulu ankhondo, m'mayendedwe, m'magetsi, m'zachuma, m'maphunziro, m'zachipatala ndi m'mafakitale ena.
