Me pēhea te whakamahi i tētahi pūwhakatikatika whatu acousto (AOM modulator) hei pana whatu
1. Te papamuri me te horopaki whanaketanga hangarau
1.1 Te Pūtake o te Reera: I te tau 1960, i hangaia e Theodore Meiman te reera rupi tuatahi, e tohu ana i te whānautanga o te hangarau reera.
1.2 Te Whanaketanga o te Taiaho: Nō muri mai, ka puta mai ngā momo taiaho, pērā i ngā taiaho hau (pērā i ngā taiaho helium neon), te taiaho haurua-ira, me ngā taiaho totoka (pērā i ngā taiaho YAG), ā, ka whānui haere te whānuitanga o tā rātou tono ki ngā mara hōia, ahumahi, me te hauora.
1.3 Whakataki whakaritenga matua: Me pumau te putanga mana o te taiaho, ā, i roto i te maha o ngā whakamahinga, kāore e taea e te taiaho te whatu tonu i te ūnga. Hei karo i te whakawhiti auau o te taiaho, ka whakauruhia he pana whatu o waho hei whakahaere tika i te taiaho ki te whakakā/whakaweto.
2. Te mātāpono mahi o te pūwhakatikatika whatu acousto (pūwhakatikatika AOM)
He taputapu whatu te AOM e whakamahi ana i te pānga acousto-optic, arā, ko te horapa o ngā ngaru oro mā roto i tētahi reo hei hanga i ngā huringa taupū whakaata ā-wā, ā, mā reira ka whakarerekē i ngā āhuatanga o ngā ngaru mārama e whiti ana i roto i te reo, pērā i te kaha, te auau, me te ahunga. I tēnei wā, e rua ngā momo whakawhitiwhiti e arotahi ana:
1.1 Te whakarara o Bragg: Ko te mea tino kitea ko te hanga a ngā ngaru mārama me ngā ngaru oro i tētahi koki motuhake, ā, ko te kaha whakarara ka kukūhia ki te mārama tuatahi, he rite ki te whatu stereo. Ko tēnei aratau te mea e whakamahia whānuitia ana mō ngā tono pana whatu.
1.2 Te whakarara Raman: He poutū te ahunga horapa o ngā ngaru mārama me ngā ngaru oro, ā, he maha ngā taumata o te tohatoha ōrite o te mārama whakarara, he rite ki te whatanga papatahi.
3. Te aratau mahi o te AOM modulator hei pana whatu
3.1 Kāore te AOM e utaina te tohu (kāore e mahi): Ka tika te haere o te taiaho mā roto (te mārama taumata-0) ka mimitia e te whakaata whakaata i te ara whatu, ā, kāore he putanga whai hua.
3.2 Tohu uta AOM (e mahi ana): ka whakaputaina te diffraction, ā, ka tukuna te mārama tuatahi i tētahi koki ka tomo ki te ara whatu e whai ake nei hei whakamahi.
Mā te whakahaere i te utaina o ngā tohu e te pūwhakatikatika AOM, ka taea te whakatutuki i te whakawhiti tere me te whakarerekētanga o te taiaho, me te whakatutuki i ngā horopaki tono e hiahia ana kia whakahaeretia te wā whitinga taiaho.
Haunga te whakamahinga hei pana whatu, ka taea hoki e AOM te whakamahi i ōna taumata mārama e rua hei whakaputa pokanoa me te hanga tohu whatu, ka taea te whakamahi i roto i te ine me ētahi atu mara. Nā te tono mahi mō te putanga mana taiaho pumau kua ara ake te hangarau pana whatu, ā, ko ngā whakarerekētanga whatu acousto (whakarerekētanga AOM) e hangai ana ki te kaupapa me te whakamahinga o te mahi pana whatu ma te whakamahi i ngā pānga acousto-whatu, inā koa te aratau diffraction Bragg.
