Putanga Ataata me nga Matapihi Mataataa Tawhiti Ka taea te whakarite mo te Military Night Vision Goggles
Nga Taipitopito Hua
Kei roto i te taputapu tirohanga po he puna rama awhina infrared me te punaha tiaki anti-glare aunoa.
He kaha te mahi, ka taea te whakamahi mo te tirotiro hoia, te rohe me te whakamarumaru takutai takutai, te tirotiro haumarutanga a te iwi, te kohinga taunakitanga, nga tikanga aukati i nga mahi hokohoko, me etahi atu i te po kaore he rama.He taputapu pai mo nga tari haumaru a te iwi, nga pirihimana mau patu, nga pirihimana motuhake, me nga kaitiaki tiaki.
Ko te tawhiti i waenga i nga kanohi ka taea te whakarite, he maamaa te whakaahua, he ngawari te mahi, he utu utu.Ka taea te whakarereke i te whakanui ma te huri i te arotahi whaainga (te hono ranei i te toronga).

Te whakatikatika kaupapa
Ko te kaupapa o te whakatikatika arotahi kia marama te kite i nga tawhiti rereke.I mua i te whakatikatika i te arotahi arotahi, Tena koa whakatikahia nga kanohi kanohi kia rite ki te tikanga kua kiia ake nei.I te whakatikatika i te arotahi arotahi, tohua he taiao pouri ake.E whakaatu ana i te Whakaahua ④, whakatuwheratia te uhi o te arotahi arotahi, anga ki te whainga, ka huri i te arotahi arotahi ki te wīra ringa ki te karaka karaka, ki te taha karaka ranei kia kitea ra ano te ahua tino marama o te taiao, ka oti te whakatikatika arotahi.I te wa e matakitaki ana i nga whaainga ki nga tawhiti rereke, me whakatika ano te arotahi whaainga kia rite ki te tikanga kua kiia ake nei.
Aratau Infrared
Ina he iti rawa te whakamarama o te taiao (te taiao pango katoa), a kaore e taea e te taputapu tirohanga po te kite i tetahi ahua marama, ka taea e koe te huri i te huringa mahi ki tetahi atu taputapu.ka uru te punaha ki te aratau "IR".I tenei wa, ka huri te rama awhina infrared o te hua ki te whakarite i te whakamahi noa i roto i te taiao pouri rawa.Tuhipoka: I roto i te aratau infrared, ki te tutaki koe ki nga taputapu rite, he ngawari ki te whakaatu i te whaainga.
