Ngā āhuatanga o te AOM acousto-optic modulator

Ngā āhuatanga oAOM acousto-whatu modulator

Ātete ki te mana whatu teitei

Ka taea e te AOM acousto-optic modulator te tu atu ki te kaha taiaho kaha, kia pai ai te haere o ngā taiaho kaha-teitei. I roto i te hononga taiaho muka-katoa, ko tekaiwhakarerekē muka-ā-whatuKa hurihia te mārama tonu ki te mārama pāorooro. Nā te iti o te huringa mahi o te pāorooro whatu, ko te nuinga o te kaha mārama kei roto i te mārama kore-raupapa. Ka horapa te mārama whakarara tuatahi me te mārama kore-raupapa i waho o te karaihe acousto-whatu i roto i te āhua o ngā hihi Gaussian rerekē. Ahakoa e tutuki ana i ngā tikanga wehewehe tino pakari, ka kohia tetahi wāhanga o te kaha mārama o te mārama kore-raupapa ki te taha o te kaiwhakakotahi muka whatu, ā, kāore e taea te tuku mā te muka whatu, ā, ka mutu ka mura mā te kaiwhakakotahi muka whatu. Ka whakanohoia te hanganga diaphragm ki te ara whatu mā roto i tētahi anga whakatikatika ono-ahu tino tika hei aukati i te tuku o te mārama whakarara i waenganui o te kaiwhakakotahi, ā, ka tukuna te mārama kore-raupapa ki te whare hei ārai i te mura o te kaiwhakakotahi muka whatu i te mārama kore-raupapa.

Te wā piki tere

I roto i tētahi hononga taiaho muka-katoa, ko te tere o te pikinga o te pāoro whatu o te AOMpūwhakarerekētanga oro-whatuMā tēnei ka taea e te pā o te tohu pūnaha te haere pai rawa atu, me te ārai hoki i te haruru turanga kei uru ki te kati ā-wā (te kuaha pā o te wā). Ko te kaupapa matua o te whakatutuki i te wā piki tere o ngā pā o te whatu ko te whakaiti i te wā whakawhiti o ngā ngaru ultrasonic mā te hihi mārama. Ko ngā tikanga matua ko te whakaiti i te diameter hope o te hihi mārama e pā mai ana, te whakamahi rānei i ngā rauemi he tere te tangi hei hanga tioata ā-wā.

He iti te whakamahinga hiko me te tino pono

He iti noa ngā rauemi o ngā waka mokowhiti, he uaua hoki ngā āhuatanga me ngā taiao uaua, ā, he nui ake ngā whakaritenga mō te whakamahinga hiko me te pono o ngā pūwhakarerekētanga muka whatu AOM.Kaiwhakarerekētanga AOMKa whakamahia he karaihe acousto-whatu motuhake, he nui te kounga acousto-whatu M2. Nō reira, i raro i ngā āhuatanga whai huatanga diffraction kotahi, he iti te whakamahinga mana taraiwa e hiahiatia ana. Ka whakamahia e te modulator acoust-whatu muka whatu tēnei hoahoa mana-iti, e kore e whakaiti noa i te hiahia mō te whakamahinga mana taraiwa me te penapena i ngā rauemi iti i roto i te waka rererangi, engari ka whakaitihia hoki te irahiko hikohiko o te tohu taraiwa me te whakaiti i te pēhanga whakamarara wera i runga i te pūnaha. E ai ki ngā whakaritenga tukanga aukati (herea) o ngā hua waka rererangi, ko te tikanga tāutanga karaihe tuku iho o ngā modulator acousti-whatu muka whatu ka whakamahia noa te tukanga here rapa silicone taha-kotahi. Kia kore te rapa silicone, ka huri ngā tawhā hangarau o te karaihe i raro i ngā āhuatanga wiri, kāore e tutuki i ngā whakaritenga tukanga o ngā hua rererangi. I roto i te hononga laser, ka whakapumautia te karaihe o te modulator acoust-whatu muka whatu mā te whakakotahi i te whakapiri miihini me te here rapa silicone. Kia ōrite te hanganga tāutanga o ngā mata o runga me raro, ā, i te wā kotahi, ka whakanuia te horahanga pā i waenga i te mata karaihe me te whare tāutanga. He painga tōna o te kaha kaha ki te whakamarara wera me te tohatoha pāmahana ōrite. Ka whakapūmauhia ngā whakapūmau tikanga mā te here i te rapa silicone. I raro i ngā āhuatanga o te pāmahana teitei me te wiri, ka neke pea, ka pā ki te mahi a te hua. Kua whakamahia te hanganga miihini inaianei hei whakapūmau i te whakapūmau muka whatu, e whakarei ake ana i te pumau o te hua, e tutuki ai hoki ngā whakaritenga tukanga o ngā hua rererangi.
