Ngā mahi whakahaere opūwhakarerekētanga oro-whatu ātea kore utu
Te wāhi wāteakaiwhakarerekētanga oro-whatuKa whakaurua, ka whakaputaa hoki ngā hihi mārama mā roto i ngā kōhao mārama tuwhera, me whakarite tika me te whakatikatika koki Bragg me te anga whakatikatika toru-ahu. Ki te whakatauritea ki te raupapa hononga muka, me whai atu ngā mahi whakatikatika ara whatu mō te raupapa wāhi kore utu, engari he painga anō hoki pērā i ngā ara whatu ngāwari me te mātakitaki ngāwari i ngā ira whakarara.
1. Ngā mahi tāutanga me te whakatikatika whānui mō te raupapa whakarerekētanga acousto-whatu ātea kore utu
Ko te tāutanga me te whakatikatika i te modulator acousto-optic wāhi kore utu he mahi whakahaere noa mō ngā tauira e rua, penei:
Hipanga 1: Kia oti te hono i ngā taputapu me ngā ara iahiko o waho katoa, whakapirihia te taputapu acousto-whatu ki runga i te anga whakatikatika toru-ahu, whakatikatikahia te teitei o te taputapu acousto-whatu ki runga, ki raro hoki kia taea ai e te hihi laser te haere mā te tūranga pai o te taputapu acousto-whatu. Kia mōhio: Ko te tūranga rama pai kei waenganui o te matotoru karaihe, me te 1.5mm te tawhiti atu i te hiko koura i mua me muri i te pēhitanga.
Hipanga 2: Whakakāhia te pūtake hiko 24V ka utaina te tohu (e taunakihia ana kia mau tonu te tohu ki te 5V i te wā e whakatika ana i te kaha o te diffraction, kia taea ai e te pūtake hiko taraiwa te mahi tonu). Whakatikatikahia te koki Bragg o tetaputapu whatu-oromaui, matau hoki hei whakatutuki i te kaha whakatītaha tuatahi teitei rawa atu.
Hipanga 3: Whai muri i te whakarerekētanga o te mārama whakarara tuatahi o te pūrere acousto-whatu, ka taea te uta i tētahi tohu kia rite ki ngā whakaritenga whakamātautau.
Momo 2 0~5V (wāhi wātea)
2.1 Whakaahuatanga Tohu Whakarerekētanga
Ko te tauranga "0-5V" e whakamahia ana hei uta i ngā tohu whakahaere, ā, he tohu anarohiko o te 0-5V. Whakawetohia ina 0V te ngaohiko whakauru, ā, ka eke te mana putanga RF ki tōna taumata teitei ina 5V te ngaohiko whakauru. Ko te tikanga whakarerekētanga o tēnei tauira he rite tonu ki te "momo anarohiko 0-5V" e honoa ana ki te muka, engari he rerekē te hanganga ara whatu, me ētahi atu mahi tāutanga me te whakatikatika.
2.2 Tikanga hononga
Ko te "RF" o te pūtake hiko taraiwa ko te putanga hiko RF. Honoa ki te raina tohu BNC e ōrite ana, ā, me hono tika te pito kē atu o te raina tohu ki te taputapu oro me te mārama mā te BNC. Kia mōhio koe kei te whakamahi tēnei tauira i te atanga BNC, he rerekē tēnei i te atanga SMA o te nuinga o ngā tauira hononga muka.
2.3 Te whakahaere mana
Whakamahia he tīwiri Phillips hei huri i te porowhita kōhao iti i te taha. Ka piki ake te kaha hurihuri ki te taha matau, ka heke iho te kaha hurihuri ki te taha maui. Kia mōhio koe kei te taha o te porowhita whakarerekētanga mana te porowhita whakarerekētanga mana, he rerekē tēnei i te putanga "whakarerekētanga amplitude" o ētahi atu tauira.
3 Momo arataki taumata teitei (wāhi wātea)
3.1 Whakaahuatanga Tohu Whakarerekētanga
Ko te tauranga 'whakarerekētanga' e whakamahia ana hei uta i ngā tohu whakahaere, ā, he tohu matihiko TTL paerewa. Kei te rere te pūhiko hiko i te taumata teitei, ā, me whakamahi he ngaohiko 5V ki te pito "whakarerekētanga" hei whakaputa i te putanga mana RF. Ina iti te pito whakarerekētanga, ka whakawetohia te putanga RF. He rite tonu ngā āhuatanga whakarerekētanga o tēnei tauira ki te "momo rerekētanga taumata-teitei" o te hononga muka, engari he rerekē te hanganga ara whatu, me ētahi atu mahi tāutanga me te whakatikatika. Kia mōhio: Kei te rere te pūhiko hiko i te taumata teitei, ā, me whakamahi he ngaohiko 5V ki te pito "whakarerekētanga" hei whakaputa i te putanga mana RF.
3.2 Te whakahaere mana
Whakamahia he tīwiri Phillips hei huri i te porowhita iti i roto i te pito "whakarerekētanga amplitude". Ka piki ake te mana hurihuri karaka, ka heke iho te mana hurihuri karaka-whakamuri. Kia mōhio koe ko te ahunga whakarerekētanga mana o tēnei tauira he ritenga kē ki te momo hononga muka taumata-tiketike!
