Ubwoko bwa moderi ya moderi

Ubwa mbere, Guhindura imbere no guhindura ibintu
Ukurikije isano iri hagati ya modulator na laser, themoderiBirashobora kugabanwa muburyo bwimbere no guhindura ibintu hanze.

01 Guhindura imbere
Ikimenyetso cyo guhindura ibintu bikorwa mugikorwa cyo kunyeganyega kwa laser, ni ukuvuga ibipimo bya oscillation ya laser bihindurwa hakurikijwe amategeko yikimenyetso cyerekana, kugirango uhindure ibiranga umusaruro wa laser kandi ugere kuri modulation.

02 Guhindura hanze
Guhindura hanze ni ugutandukanya laser generation na modulation. Yerekeza ku gupakira ibimenyetso byahinduwe nyuma yo gukora lazeri, ni ukuvuga, modulator ishyirwa munzira nziza hanze ya laser resonator.
Modulasiyo yerekana ibimenyetso byongeweho kuri modulator kugirango ikore ibintu bimwe na bimwe bifatika biranga icyiciro cya moderi ihinduka, kandi iyo laser iyinyuzemo, ibipimo bimwe na bimwe byumucyo wumucyo birahindurwa, bityo bitwara amakuru yoherezwa. Kubwibyo, modulisiyo yo hanze ntabwo ihindura ibipimo bya laser, ahubwo ni uguhindura ibipimo bisohoka laser, nkuburemere, inshuro, nibindi.

Icya kabiri,moderigushyira mu byiciro
Ukurikije uburyo bwimikorere ya modulator, irashobora gushyirwa mubiceamashanyarazi ya optique, modulasi ya acoustooptic, magneto-optique modulasiyo na modulisiyo itaziguye.

01 Guhindura mu buryo butaziguye
Imodoka yo gutwarasemiconductor lasercyangwa diode isohora urumuri ihindurwa muburyo butaziguye nicyapa cyamashanyarazi, kugirango urumuri rusohoka ruhindurwe hamwe no guhindura ibimenyetso byamashanyarazi.

(1) Guhindura TTL muburyo butaziguye
Ikimenyetso cya TTL cyongewe kumashanyarazi ya laser, kugirango amashanyarazi ya laser ashobore kugenzurwa binyuze mubimenyetso byo hanze, hanyuma lazeri isohoka inshuro irashobora kugenzurwa.

(2) Guhindura kugereranya muburyo butaziguye
Usibye ibimenyetso bya laser bitanga ibimenyetso bisa (amplitude iri munsi ya 5V yerekana ibimenyetso byerekana ibimenyetso)

02 Guhindura amashanyarazi
Guhinduranya ukoresheje ingaruka za electro-optique bita electro-optique modulation. Ishingiro ryumubiri rya moderi ya electro-optique ningaruka za electro-optique, ni ukuvuga, mugikorwa cyumurima wamashanyarazi washyizweho, indangagaciro yo kwangirika ya kristu zimwe na zimwe zizahinduka, kandi mugihe umucyo wumucyo unyuze muri ubu buryo, ibiranga kwanduza bizaba bigira ingaruka kandi bigahinduka.

03 Guhindura Acousto-optique
Ishimikiro ryumubiri rya moderi ya acousto-optique ningaruka ya acousto-optique, yerekeza kubintu byerekana ko imiraba yumucyo ikwirakwizwa cyangwa ikwirakwizwa numurima ndengakamere iyo ikwirakwiza hagati. Iyo indangantego yo guhindagurika yikigereranyo ihinduka mugihe cyo gukora indangururamajwi, itandukaniro rizabaho mugihe urumuri rwumucyo rwakwirakwiriye hagati, kandi ubukana, inshuro nicyerekezo cyumucyo utandukanya bizahinduka hamwe nimpinduka yumurima wikirenga.
Guhindura Acousto-optique ni inzira yumubiri ikoresha ingaruka za acousto-optique kugirango yikoreze amakuru kumatwara ya optique. Ikimenyetso cyahinduwe gikorerwa kuri transducer ya electro-acoustic muburyo bwikimenyetso cyamashanyarazi (amplitude modulation), kandi ibimenyetso byamashanyarazi bihuye bihinduka mumurima wa ultrasonic. Iyo urumuri rwumucyo runyuze muri acousto-optique, umutwara wa optique arahindurwa kandi bigahinduka imbaraga zahinduwe "zitwara" amakuru.

04 Guhindura Magneto-optique
Magneto-optique ihinduranya ni porogaramu ya Faraday ya electromagnetic optique yo kuzunguruka. Iyo imirasire yumucyo ikwirakwira binyuze muri magneto-optique igereranya nicyerekezo cyumurima wa magneti, ibintu byo kuzenguruka indege ya polarisiyasi yumucyo ucanye urumuri bita magnetique rotation.
Umwanya wa magnetiki uhoraho ukoreshwa muburyo bwo kugera kuri magnetique. Icyerekezo cyumuzunguruko wumurongo wumurongo uri muburyo bwa axial yicyerekezo giciriritse, kandi kuzenguruka kwa Faraday biterwa na axial ya magnetiki yumurongo. Kubwibyo, mugucunga imiyoboro yumurongo mwinshi kandi ugahindura imbaraga za magnetique yumurongo wikimenyetso cya axial, kuzenguruka Inguni yindege ya optique yinyeganyeza irashobora kugenzurwa, kugirango amplitude yumucyo binyuze muri polarizer ihinduka hamwe nimpinduka ya θ Inguni , kugirango tugere kuri modulation.
