Kuenzaniswa uye Modulation Scheme yeLaser Modulator

Laser modulatorrudzi rwezvemhando yekudzora laser zvikamu, hazviiti secretldals, lens uye zvimwe zvinhu, kana zvakabatanidzwa zvakanyanya sevanopararira,Laser Midziyo, idhigirii rakakwira rekubatanidza, mhando uye mabasa ezvakagadzirwa kirasi zvigadzirwa. Kubva pakuratidzwa kwechiedza chechiedza, zvinogona kuoneka kuti zvinhu zvinokanganisa mafungu echiedza ari kuwanda a (r), phase φ uye mana zvikamu zvekunyepedzera, nekudzora zvinhu izvi zvinogona kuchinja mamiriro eiyo mwenje wechiedza, iyo inoenderana laser modulator ndiyoIntensity modulator, Phase Modulator, frequency shinter uye deflector.

1. Instensity modulate: yakashandiswa kunongedza kukura kweiyo laser.

2. Phase Modulator. Kune marudzi mazhinji evanofamba-famba, uye nheyo dzawo dzakasiyana kwazvo, dzakadai semagetsi emagetsi, etc. .

4. Deflector: Inoshandiswa kuchinja nzira yekupararira kweBlam, iyo Carvanometer System ndechimwe chazvo, kuwedzera nekukurumidza mems carvanometer, Electro-Optical deflettor uye acousto-Opotto-Optical deflector.

Isu tine general pfungwa yeiyo Laser Modulator, izvo, izvo izvo zvinogona kudzora masimba uye kuchinja zvimwe zvivakwa zve laser, asi unoda kunyatsoisa zvigadzirwa zveiyo laser modulator, chinyorwa chete hachina kukwana. Saka, chekutanga pane zvese, tarisa pane iyo yekuwedzera modulator. Mirayiritor yemhando serudzi rweModulator yakashandiswa zvakanyanya mumhando dzese dzezvirongwa, nhasi mashandisirwo emuchina uye chinwiwa chechiratidzo chechiratidzo.

1. Mechancal Scheme: Mechanical Simba Modulator ndiyo yekutanga uye zvakanyanya kushandiswa zvakanyanya Simba modulator. Iyo nheyo ndeyekuchinja huwandu hwechiyero chechiedza uye pl mwenje mune yakajeka mwenje nekutenderera hafu-wave mundiro, uye kupatsanura mwenje nePolarizer. Kubva pane yekutanga bhuku rekugadzirisa kusvika nhasi rakanyanya otomatiki uye yakakwirira-chaiyo, marudzi ayo echigadzirwa uye kukura kwekushandisa kwave kukura zvakanyanya.

2. Iyo polarization mamiriro eiyo polarized bheji shanduko mushure mekunge Electro-Optic Crytrive munda yemagetsi inoshandiswa, uye ipapo polisization inosarudzwa ne polarizarizer. Kukura kweiyo yakagadzirwa mwenje kunogona kudzorwa nekuchinja kusimba kwemunda wemagetsi, uye kusimuka / kudonha kwemucheto kwe ns hukuru kunogona kusvikwa.

3. Acousto-Optic Scheme: Acousto-Optic Modulator inogona zvakare kushandiswa seyakawedzera modulator. Nekuchinja kushanduka kwemaswavo, iro simba re 0 mwenje uye 1 mwenje unogona kudzorwa kuti uwane chinangwa chekugadzirisa kukosha kwechiedza. Acoustooptic Gate (Optical Attenuator) ine maitiro ekukurumidza modulation kumhanya uye yakanyanya kukuvara chikumbaridzo.

4 Liquid Crystal Solution: Liquid Crystal Chishandiso inowanzo shandiswa seyakafa masaya emifananidzo, nekushandisa drive yekukanda miviri yekrisiti yekuwedzera, inogona kugadzirwa mune yemvura yekuvhara kana kusiana Atteniator, chigadzirwa chine hurongwa hombe kubudikidza nechiedza, hunhu hwakanyanya hwekuvimbika.
