Tuatahi, te whakarerekētanga ā-roto me te whakarerekētanga ā-waho
E ai ki te whanaungatanga whanaunga i waenga i te modulator me te laser, ko tewhakarerekētanga taiahoka taea te wehewehe ki te whakarerekētanga ā-roto me te whakarerekētanga o waho.
01 whakarerekētanga ā-roto
Ka whakahaerehia te tohu whakarerekētanga i roto i te tukanga o te wiri taiaho, arā, ka hurihia ngā tawhā o te wiri taiaho kia rite ki te ture o te tohu whakarerekētanga, kia huri ai ngā āhuatanga o te putanga taiaho me te whakatutuki i te whakarerekētanga.
(1) Whakahaere tika i te pūtake papu taiaho kia tutuki ai te whakarerekētanga o te kaha taiaho putanga, me te mea kei reira, kia taea ai te whakahaere e te pūtake hiko.
(2) Ka whakanohoia te huānga whakarerekētanga ki roto i te resonator, ā, ka whakahaerehia te huringa o ngā āhuatanga ā-tinana o te huānga whakarerekētanga e te tohu hei whakarerekē i ngā tawhā o te resonator, ā, ka whakarerekē i ngā āhuatanga putanga o te taiaho.
02 Te whakarerekētanga o waho
Ko te whakarerekētanga o waho ko te wehenga o te whakaputanga taiaho me te whakarerekētanga. E pā ana ki te utaina o te tohu whakarerekētanga i muri i te hanganga o te taiaho, arā, ka whakanohoia te whakarerekētanga ki te ara whatu i waho o te resonator taiaho.
Ka tāpirihia te ngaohiko tohu whakarerekētanga ki te whakarerekētanga hei hanga i ētahi āhuatanga ā-tinana o te whakarerekētanga ā-whatu, ā, ina haere te taiaho mā roto, ka whakarerekētia ētahi tawhā o te ngaru mārama, ā, ka haria ngā mōhiohio hei tuku. Nō reira, ehara te whakarerekētanga o waho i te whakarerekētanga o ngā tawhā taiaho, engari i te whakarerekētanga o ngā tawhā o te taiaho putanga, pērā i te kaha, te auau, me ētahi atu.
Tuarua,kaiwhakarerekē taiahowhakarōpūtanga
E ai ki te tikanga mahi o te modulator, ka taea te whakarōpū kiwhakarerekētanga hiko-whatu, te whakarerekētanga acousto-whatu, te whakarerekētanga magneto-whatu me te whakarerekētanga tika.
01 Te whakarerekētanga tika
Ko te ia taraiwa o terēhia haurua-iraka whakarerekētia tikatia rānei te tīoata whakaputa mārama e te tohu hiko, kia whakarerekētia ai te mārama putanga me te panonitanga o te tohu hiko.
(1) Te whakarerekētanga TTL i roto i te whakarerekētanga tika
Ka tāpirihia he tohu matihiko TTL ki te pūtake hiko taiaho, kia taea ai te whakahaere i te ia o te puku taiaho mā te tohu o waho, kātahi ka taea te whakahaere i te auau putanga taiaho.
(2) Te whakarerekētanga ā-tauira i roto i te whakarerekētanga tika
Haunga te tuku mana taiaho me te tohu taiaho (ka taea e te kaha iti iho i te 5V te huri i te ngaru tohu), ka taea te hanga i te ngaohiko whakauru tohu o waho e rite ana ki te iahiko taraiwa taiaho rerekē, ka taea te whakahaere i te mana taiaho putanga.
02 Te whakarerekētanga hiko-whatu
Ko te whakarerekētanga mā te whakamahi i te pānga hiko-whatu ka kiia ko te whakarerekētanga hiko-whatu. Ko te pūtake ā-tinana o te whakarerekētanga hiko-whatu ko te pānga hiko-whatu, arā, i raro i te mahi a te papa hiko kua whakamahia, ka huri te taupū whakaata o ētahi tioata, ā, ina haere te ngaru mārama mā roto i tēnei reo, ka pāngia, ka rerekē hoki ōna āhuatanga tuku.
03 Whakarerekētanga oro-whatu
Ko te pūtake ā-tinana o te whakarerekētanga acousto-whatu ko te pānga acousto-whatu, e pā ana ki te āhuatanga e horapa ana, e marara ana rānei ngā ngaru mārama e te mara ngaru tipua i te wā e horapa ana i roto i te reo. Ina huri te taupū whakaata o te reo i ia wā hei hanga i tētahi whatanga taupū whakaata, ka puta te diffraction ina horapa te ngaru mārama i roto i te reo, ā, ka huri te kaha, te auau me te ahunga o te mārama diffractive me te huringa o te mara ngaru supergenerated.
Ko te whakarerekētanga ā-tinana oro-whatu he tukanga ā-tinana e whakamahi ana i te pānga oro-whatu hei uta i ngā mōhiohio ki runga i te kaikawe auau whatu. Ka pāngia te tohu whakarerekētia ki runga i te transducer hiko-oro i roto i te āhua o te tohu hiko (whakarerekētanga whānui), ā, ka hurihia te tohu hiko e rite ana hei mara ultrasonic. Ina pā te ngaru mārama mā roto i te reo oro-whatu, ka whakarerekētia te kaikawe whatu, ka huri hei ngaru whakarerekētanga kaha e "kaikawe" ana i ngā mōhiohio.
04 Te whakarerekētanga aukume-whatu
Ko te whakarerekētanga aukume-whatu he whakamahinga o te pānga hurihuri whatu aukume a Faraday. Ina horapa ngā ngaru mārama mā roto i te reo aukume-whatu e whakarara ana ki te ahunga o te papa aukume, ko te āhuatanga hurihuri o te papa pōraritanga o te mārama pōrari rārangi ka kiia ko te hurihuri aukume.
Ka whakamahia he papa aukume pumau ki te reo hei whakatutuki i te mātotoru aukume. Ko te ahunga o te papa aukume o te ara iahiko kei roto i te ahunga tuaka o te reo, ā, ko te hurihanga Faraday e whakawhirinaki ana ki te papa aukume o te au tuaka. Nō reira, mā te whakahaere i te ia o te koiri auau-tiketike me te whakarerekē i te kaha o te papa aukume o te tohu tuaka, ka taea te whakahaere i te koki hurihanga o te papa wiri whatu, kia rerekē ai te kaha o te mārama i roto i te pōrari i te huringa o te koki θ, kia tutuki ai te whakarerekētanga.
