Ihame shingiro rya Modulator Optique

Modutor ya Optique, ikoreshwa mu kugenzura ubukana bw'urumuri, gushyira mu bikorwa bya electique, thermooptic, acoustoptic, byose bya Optique, igitekerezo cyibanze cya electro-optic ingaruka za electro-optic.
Modulator ya Optique nimwe mubikoresho byingenzi bihujwe muburyo bwihuse kandi buciriritse. Modulator yoroheje ukurikije ihame ryimihindaguro, irashobora kugabanywamo electro-optic, igitekerezo, ingaruka mbi, etage.

TheModutor ya electro-optiquenigikoresho gigenga indangagaciro irongera, itoroshye, amplitude cyangwa icyiciro cyo gusohoka mumucyo binyuze mu guhindura voltage cyangwa umurima w'amashanyarazi. Birasumba ubundi bwoko bwa modulator mubibazo byo gutakaza, gukoresha imbaraga, kwishyira hamwe no kwishyira hamwe, kandi nabyo na modulator ikoreshwa cyane kurubu. Muburyo bwo kohereza neza, kwanduza no kwakirwa, modulator ya optique ikoreshwa mugukemura ubukana bwurumuri, kandi uruhare rwayo ni ngombwa cyane.

Intego yo guhinduranya ni uguhindura ibimenyetso byifuzwa cyangwa amakuru yandujwe, harimo "gukuraho urusaku, no kurwanya urusaku, kugirango byoroshye gutunganya, kohereza no kumenya.

Ubwoko bw'imyitwarire irashobora kugabanywamo ibyiciro bibiri bigari ukurikije aho amakuru yuzuye kumucyo:

Imwe nimbaraga zo gutwara isoko yahinduwe ibimenyetso byamashanyarazi; Ikindi ni uguhindura ibitekerezo bitaziguye.

Ibyambere bikoreshwa cyane cyane kubitumanaho bya optique, kandi ibya nyuma bikoreshwa cyane cyane kubitekerezo bya optique. Kuri bugufi: modulation yimbere hamwe no guhinduranya hanze.

Dukurikije uburyo bwo guhindura, ubwoko bwa modulation ni:

1) Imbaraga za module;

2) Icyiciro cya Pudulation;

3) Guhinduranya;

4) Havency na Waveleurglet modulation.

1.1, imbaraga

Uburyo bworoshye bworoshye nimbaraga zumucyo nkuko byahinduwe, gukoresha ibintu byo hanze kugirango bipime ikimenyetso cyangwa gutinda gusiba urumuri rwihuta, kugirango hashobore gupima urumuri rwihuta, hanyuma umubare wo gupimana kugirango uhagarike ubudahwema.

1.2, Guhindura icyiciro

Ihame ryo gukoresha ibintu byo hanze kugirango uhindure icyiciro cyumucyo no gupima ubwinshi muguhitamo icyiciro cyicyiciro cyitwa Icyiciro cya Oppotique.

Iki cyiciro cyumucyo kigenwa nuburebure bwumubiri bwo gukwirakwiza urumuri, ikwirakwizwa ryumucyo usobanura no gukwirakwiza icyiciro cyacyo hejuru hashobora guhindurwa ibipimo byavuzwe haruguru kugirango tugere ku mose.

Kuberako urutonde rwumucyo muri rusange ntirushobora kubona impinduka yicyiciro cyumucyo, tugomba gukoresha ikoranabuhanga ryibice kugirango tumenye ibice bibiri: kugirango tugere ku bice bibiri: kugirango tugere ku bice bibiri: kugira ngo tumenye ibice bibiri: imwe ni uburyo bw'umubiri bwo guhindura icyiciro cy'icyiciro; Iya kabiri ni ukwivanga.

1.3. Guhinduranya

Inzira yoroshye yo kugera ku moko yoroheje ni ukuzenguruka abapalarie ebyiri ugereranije. Ukurikije Theorem, ibisohoka byoroheje ni njye = i0cos2α

Aho: I0 igereranya ubukana bwumucyo bwanyuze nabadelariri bombi mugihe indege nyamukuru ihoraho; Alpha yerekana inguni hagati yindege ebyiri za polarisers.

1.4 inshuro nyinshi hamwe na wavele uburebure

Ihame ryo gukoresha ibintu byo hanze kugirango uhindure inshuro cyangwa uburebure bwumucyo no gupima ubwinshi bwo hanze no kumenya impinduka mumico cyangwa umugozi wijimye witwa inshuro nyinshi.
