Te hanganga pūnaha o te modulator acousto-optical

Te hanganga pūnaha okaiwhakarerekētanga oro-whatu
Ko te AOM Modulator te taputapu whakarerekētanga ā-waho e whakamahia whānuitia ana i waho o te kōhao taiaho, nō roto i te pūnaha hangarau whakarerekētanga o waho. E whakawhirinaki ana ki ngā pānga ā-tinana o te hononga acousto-whatu hei whakatutuki i te whakahaere hihi whakakā/whakaweto, kaha me te auau. Koinei te kaupapa whakarerekētanga e whakamahia whānuitia ana i roto i te tohu taiaho ahumahi, te tapahi tika, te rangahau pūtaiao i te ara whatu, me ngā taputapu radar taiaho mana iti me te reo.
Te hanganga pūnaha,
Ko te katoawhakarerekētanga acousto-whatuE rima ngā wae matua o te pūnaha: te karaihe acousto-whatu, te whakawhiti piezoelectric, te pūtake puku RF, te turanga whakamarara wera, me te turanga hononga whatu. Ka mahi tahi ia waeine hei whakarite i te pumau o te whakarerekētanga.
1. Tioata whatu acousto: Ko te kaikawe matua o te taunekeneke acousto-whatu, koinei te rauemi mata matua e whakatau ana i te roopu auau whakarerekētanga, te roopu auau tuku, me te paepae kino. E toru ngā wāhanga o ngā tioata e whakamahia whānuitia ana: te kuata hanumi e tika ana mō te taiaho 1064nm/CO₂, e tika ana mō ngā āhuatanga ahumahi mana-teitei; He pai ngā āhuatanga auau-teitei o TeO₂, ā, he whirihoranga paerewa mō ngā mīhini tohu mana iti me te reo; He hototahi te Gallium phosphide ki te taiaho ultraviolet 355nm mō te miihini tika.
2. Whakawhiti hiko piezoelectric: he mea whakapiri ki te mata o te karaihe hei whakatutuki i te huringa oro-hiko, ka whakamahia e ngā hua teitei te tukanga whakarewa pāmahana-iti korehau hei whakapai ake i te pono.
3. Pūtake taraiwa RF: te matua whakahaere hiko, e rua ngā wāhanga: ka whakawhirinaki te taraiwa matihiko TTL ki ngā taumata teitei me te iti hei tahuri me te whakaweto i te RF, koinei te otinga matua mō te tohu ahumahi; Ka tutuki i te taraiwa whakatauira te whakatikatika tonu i te kaha o te mārama mā te whakarerekē i te mana RF, e whakamahia whānuitia ana i roto i ngā horopaki rangahau pūtaiao. Ko te whānuitanga auau taraiwa tuku iho ko te 20MHz ~ 400MHz.
4. Pūtake whakamātao wera: mana-teiteiKaiwhakahaere AOMme te whakamatao wai, ka taea te whakamahi i te whakamatao hau konumohe koranu hei ārai i te hekenga o te whai huatanga o te diffraction i te pāmahana tiketike, arā, he iti, he reo hoki te mana.
5. Pūtake Whatu: He taputapu tika e taea ai te whakatikatika i te koki taunga kia tino tau ai te taiaho ki te koki Bragg.
