He aha te Māramatanga Whakawhanaunga? Me pēhea te whakamārama i tētahi kauwhata o te kōpiko māramatanga whakawhanaunga?

1.He aha te māramatanga whanaunga?

He āhua pōuri ake te āhua o ngā taha o te mea; ka taea tēnei te whakapai ake? I tēnei rā ka tirohia tēnei tawhā—te māramatanga whanaunga.

Whakamāramatanga: Ko te māramatanga te nui o te kanapa e whakaatuhia ana e tētahi mea, e tētahi mata rānei ina whakamāramahia e tētahi pūtake mārama.

Ko te māramatanga whanaunga e pā ana ki te ōwehenga o te kanapa i te taha o te tirohanga ki te kanapa i waenganui, e whakaaturia ana hei ōrau. He tawhā e whakaatu ana i te āhuatanga whatu i puta mai i te aukati, i te whakaiti rānei i tētahi wāhanga o te mārama e tomo ana ki te arotahi. I roto i te hoahoa whatu, ka whakaratohia e te pihi māramatanga whanaunga he whakaaturanga tirohanga o te kanapa i ngā tūranga rerekē i roto i te tirohanga e pā ana ki te pokapū.

2.He aha ngā āhuatanga e pā ana ki te māramatanga ōrite?

(1)Tuawhāpmana ocTure osine

Ka heke te kanapa i te taha o te tirohanga, ā, e pā ana tēnei ki te mana tuawhā o te cosine o te koki tirohanga. Ko te mana tuawhā o te ture cosine he mātāpono nui e whakaahua ana i te whakaiti i te kaha o te mārama i ngā koki rerekē, ā, he mea tino tika mō te tātari i ngā āhuatanga irahiko o ngā pūtake pūwāhi, o ngā pūtake mārama iti rānei i raro i ngā āhuatanga motuhake.

Ina pā te mārama mai i tētahi pūtake pūwāhi ki tētahi mata i te koki θ, ka rite te kaha (te hihi rānei) e whiwhihia ana e taua mata ki te cos⁴θ, arā, I(θ) = I(0)·cos⁴θ. Kei hea:

Ko I(0) te kaha o te mārama ina tau te pūtake mārama ki te taha poutū (θ=0°);

Ko θ te koki i waenganui i te hihi mārama e tau mai ana me te mata noa;

Ko I(θ) te kaha o te mārama i te koki θ.

E whakamārama ana tēnei tātai he aha i poto ai te roa o te arotahiNgā karaihe FAhe nui te hekenga o te kanapa i ngā taha. Nā te mea he whānui te tirohanga a ngā karāhe arotahi poto, he māmā noa te mārama mai i te tauira i runga ake nei ka pōuri ake ngā taha, ahakoa kāore he awe o ētahi atu āhuatanga.

(2)Te tāpiri i ngā whakaahua poto

Ka āraia ētahi o ngā hihi mārama e te oko arotahi, e ngā taha rānei o ngā wāhanga arotahi, ka heke te kaha mārama e whiwhihia ana i ngā taha o te pūoko kāmera. Ka kiia tēnei āhuatanga ko te vignetting. E whakaatu ana te pakiwaituhi i raro nei i te hanganga o te vignetting.

Te hanganga o te whakarāpopototanga

I roto i ngā karu arotahi o te ao tūturu, nā te mea kei reira ngā hapa, me ārai ā-ringa ētahi o ngā hihi mārama kino e pā ana ki te hanganga o te ahua. Ka whakapai ake tēnei i te kounga o te ahua, engari ka whakanui ake hoki i te vignetting, ka whakaiti i te māramatanga ōrite.

(3)Kāore e hototahi te rahi o te whakairinga arotahi me te rahi o te maramara

Ina te porowhita ahua o tearotahihe iti iho i te rahi hauroki o te pūoko, ka pōuri ake ngā taha o te tirohanga, ka mangu rawa rānei, ā, i taua wā ka 0% te māramatanga whanaunga i ngā taha.

3.Me pēhea te whakamārama i tētahi kauwhata pihi whakamārama whanaunga?

Mahere whakamārama whanaunga

I roto i te ahua, te pūwāhi 1: Ko ngā kōpiko tae rerekē e tohu ana i te māramatanga whanaunga i ngā tautuhinga kōhao rerekē.

I roto i te ahua, te pūwāhi 2: Ko te tuaka whakapae e tohu ana i ngā teitei ahua rerekē o te arotahi (ka whakamahia te aratau teitei haurua-ahua, ko te pokapū ko te 0).

I roto i te ahua, te pūwāhi 3: Ko te tuaka poutū e tohu ana i te uara tau o te māramatanga whanaunga i ngā pūwāhi e toru.

I roto i te ahua, te pūwāhi 4: Koinei te ingoa, te tau tuhi rānei o tēneiarotahi.

Pūwāhi 6 o te ahua: I tēhea awhe roangaru i whakamatautauria ai te pihi whakamārama arotahi?

Tauira:

Pūwāhi 5 i roto i te ahua: Ki te inehia ki te arotahi 16mm i te whakatuwheratanga F1.6 i te awhe roangaru 860nm-900nm, ko te māramatanga whanaunga i te teitei haurua-ahua o te 3.5mm tata ki te 78% ki te whakaritea ki te pokapū.
