Ngā karaihe matawaie whakamahia whānuitia ana i roto i te AOI, te tirotiro tā, te tirotiro papanga kore-whatu, te tirotiro hiako, te tirotiro ara rerewē, te tirotiro me te tātari tae me ētahi atu ahumahi. Kei roto i tēnei tuhinga he kupu whakataki ki ngā karāhe matawai rārangi.

He Kupu Whakataki ki te Arotahi Matawai Raina

1) Te ariā o te arotahi matawai rārangi:

Ko te arotahi CCD raina-aratau he arotahi FA mahi-teitei mō ngā kāmera raupapa pūoko raina e rite ana ki te rahi o te ahua, te rahi pika, ā, ka taea te whakamahi ki ngā tirotiro tino tika.

2) Ngā āhuatanga o te arotahi matawai rārangi:

1. He mea hanga motuhake mō ngā tono matawai taumira teitei, tae atu ki te 12K;

2. Ko te mata ūnga whakaahua hototahi mōrahi he 90mm, mā te whakamahi i tētahi kāmera matawai rārangi roa ake;

3. Taumira teitei, rahi pika iti rawa tae atu ki te 5um;

4. He iti te tere whakapōturi;

5. Whakanui 0.2x-2.0x.

Ngā Whakaaro mō te Kōwhiri i tētahi Arotahi Matawai Raina

He aha tātou me whakaaro ai ki te kōwhiringa arotahi ina whiriwhiri ana i tētahi kāmera? Ko ngā taumira o ngā kāmera matawai raina noa i tēnei wā ko te 1K, 2K, 4K, 6K, 7K, 8K, me te 12K, ā, ko ngā rahi pika ko te 5um, 7um, 10um, me te 14um, nō reira ko te rahi o te maramara kei waenga i te 10.240mm (1Kx10um) me te 86.016mm (12Kx7um).

He mārama, kāore te atanga C i te tutuki i ngā whakaritenga, nā te mea ka taea anake e te atanga C te hono i ngā maramara me te rahi mōrahi o te 22mm, arā, 1.3 inihi. Ko te atanga o te maha o ngā kāmera ko F, ​​M42X1, M72X0.75, me ētahi atu. Ko ngā atanga arotahi rerekē e rite ana ki te arotahi whakamuri rerekē (tawhiti flange), e whakatau ana i te tawhiti mahi o te arotahi.

1) Whakanui whatu (β, Whakanui)

Kia whakatauhia te taumira o te kāmera me te rahi o te pika, ka taea te tatau i te rahi o te pūoko; ko te rahi o te pūoko i wehea ki te tirohanga whānui (FOV) he rite ki te whakanui whatu. β=CCD/FOV

2) Atanga (Maunga)

Ko te nuinga o ēnei ko C, M42x1, F, T2, Leica, M72x0.75, me ētahi atu. Whai muri i te whakaū, ka taea e koe te mōhio ki te roa o te atanga e rite ana.

3) Te Tawhiti o te Flange

Ko te arotahi whakamuri e pā ana ki te tawhiti mai i te papa atanga kāmera ki te maramara. He tawhā tino nui tēnei, ā, ka whakatauhia e te kaihanga kāmera i runga i tana ake hoahoa ara whatu. Ahakoa he rite tonu te atanga o ngā kāmera mai i ngā kaihanga rerekē, tera pea he rerekē te arotahi whakamuri.

4) MTF

Mā te whakanui whatu, te atanga, me te arotahi whakamuri, ka taea te tatau i te tawhiti mahi me te roa o te mowhiti hononga. Whai muri i te whiriwhiri i ēnei, tētahi atu hononga nui, arā, kia kite mēnā he pai te uara MTF? He maha ngā kaihanga tirohanga kāore e mārama ki te MTF, engari mō ngā karaihe teitei, me whakamahi te MTF hei ine i te kounga whatu.

He nui ngā mōhiohio e kapi ana i te MTF pērā i te rerekētanga, te taumira, te auau ā-wāhi, te rerekētanga tae, me ētahi atu, ā, e whakaatu ana i te kounga whatu o te pokapū me te taha o te arotahi me te tino taipitopito. Ehara i te mea ko te tawhiti mahi me te tirohanga whānui anake e tutuki ana i ngā whakaritenga, engari kāore te rerekētanga o ngā taha e ranea ana, engari me whakaaro anō mēnā me whiriwhiri he arotahi taumira teitei ake.
