Gutondekanya no guhindura gahunda ya laser modulator

Moderini ubwoko bwo kugenzura lazeri, ntabwo aribyingenzi nkibintu bya kristu, lens nibindi bice, cyangwa nkibisanzwe cyane nka laseri,ibikoresho bya laser, ni urwego rwohejuru rwo kwishyira hamwe, ubwoko nimirimo yibikoresho byo murwego rwibikoresho. Uhereye ku mvugo igoye yerekana urumuri, birashobora kugaragara ko ibintu bigira ingaruka kumurabyo wumucyo ari ubukana A (r), icyiciro Φ (r), inshuro ω hamwe nibintu bine byerekezo byogukwirakwiza, mugenzura ibyo bintu bishobora guhindura imiterere yumuraba wumucyo, moderi ijyanye na laser ni yomodulator, moderi yicyiciro, guhinduranya inshuro na deflector.

1.

2. Icyiciro: ikoreshwa mugucunga icyiciro cyibiti, kwiyongera kwicyiciro bita lag, kugabanuka kwicyiciro cyitwa gurş. Hariho ubwoko bwinshi bwa modulator, kandi amahame yakazi yabo aratandukanye cyane, nka moderi ya fotoelastic modulator, LN yihuta ya electro-optique icyiciro cya modulator, amavuta ya kirisitu ihindagurika yimpapuro zitinda, nibindi, byose ni modulatori yicyiciro ishingiye kumahame atandukanye yakazi.

3. Guhindura inshuro: bikoreshwa muguhindura inshuro yumurabyo wumucyo, bikoreshwa cyane muri sisitemu yohejuru ya laser cyangwa ibikoresho byo gushushanya, hamwe na acousto-optique ya transfert nkumuhagarariye bisanzwe.

Dufite igitekerezo rusange cya moderi ya moderi, ni ukuvuga ibice bishobora kugenzura no guhindura ibintu bimwe na bimwe bifatika bya laser, ariko dushaka kumenyekanisha byimazeyo ibicuruzwa byihariye bya moderi ya laser, gusa ingingo iri kure bihagije. Rero, mbere ya byose, wibande ku bukana modulator. Moderi yubukorikori nkubwoko bwa modulator ikoreshwa cyane muburyo bwose bwa sisitemu ya optique, ubwoko bwayo, imikorere itandukanye irashobora gusobanurwa nkibigoye, uyumunsi kugirango tubamenyeshe gahunda enye ihuriweho nimbaraga: gahunda yubukanishi, gahunda ya electro-optique, gahunda ya acousto-optique na sisitemu ya kristu.

1. Gahunda ya mashini: moderi yingufu za moderi niyambere kandi ikoreshwa cyane modulator. Ihame ni uguhindura igipimo cyumucyo na p urumuri rwumucyo uhinduranya igice cya kabiri cyumuraba, no kugabanya urumuri na polarizer. Kuva mu ntangiriro yintoki zahinduwe kugeza uyumunsi zikoresha cyane kandi zisobanutse neza, ubwoko bwibicuruzwa niterambere ryimikorere byarakuze cyane.

. Imiterere ya polarisiyasi yimirasire ihindagurika nyuma ya electro-optique kristal hamwe numurima wamashanyarazi ikoreshwa, hanyuma polarisiyasi igabanijwemo ibice na polarizer. Ubukomezi bwurumuri rusohoka burashobora kugenzurwa muguhindura ubukana bwumuriro wamashanyarazi, kandi kuzamuka / kugwa kumpande ya ns irashobora kugerwaho.

3. Gahunda ya Acousto-optique: moderi ya acousto-optique irashobora kandi gukoreshwa nkumu moderi wimbaraga. Muguhindura imikorere itandukanye, imbaraga zumucyo 0 numucyo 1 zirashobora kugenzurwa kugirango ugere ku ntego yo guhindura ubukana bwurumuri. Irembo rya Acoustooptic (optique attenuator) rifite ibiranga umuvuduko wihuta kandi byangiritse cyane.

4 Amazi ya kirisiti yumuti: ibikoresho bya kristu byamazi bikoreshwa kenshi nka plaque ihindagurika cyangwa isahani ihindagurika, ukoresheje voltage ya drayike kumpande zombi zamazi yisanduku ya kristu kugirango hongerwemo ibintu bya polarisiyonike yuzuye, birashobora gukorwa mumashanyarazi ya kirisiti cyangwa ibintu bihindagurika, ibicuruzwa bifite aperture nini binyuze mumucyo, biranga kwizerwa cyane.
