Arotahi Hiraka (arotahi Si) mō ngā Whakamahinga Pūwhero
Ngā mōhiohio hua:
He karaihe whatu te karaihe silicon i hangaia ki te silicon. He rauemi tioata te silicon (Si) e whakamahia whānuitia ana i roto i ngā pūnaha whatu infrared e mahi ana i roto i te roopu hihi 3 ki te 5µm. Ko tōna taupū whakaata e tata ana ki te 3.4 puta noa i te awhe. He iti noa iho te mātotoru i waenga i ngā rauemi infrared noa, he haurua noa iho i te Ge, GaAs me te ZnSe. Nō reira, he mea pai te rauemi silicon mō te pūnaha e āwangawanga ana mō te taumaha. He pakeke ake te silicon, he iti ake hoki te utu i te nuinga o ngā rauemi infrared noa, ka whakaiti i te utu rauemi me te whakanui ake i te utu hanga i te wā kotahi.
He pai te silicon mō te tono MWIR engari nā te kaha o te mimiti i runga ake i te 6 micron, kāore i te pai mō te tono LWIR. Ka taea hoki te whakamahi hei papa whakaata mō te tono laser nā tōna kawe wera, tōna mama, me tōna pakeke.
Te Roanga Ngaru o te Pūngāwerewereka taea te hanga i ngā momo āhua o te karaihe silicon mengā mata papatahi, ngā mata kōpiko, ngā mata pūkohu, ngā mata āporo me ngā mata whakarara.Ko te silicon te mea tino rongonui mō ngā pūnaha e mahi ana i te rohe hihi 3-5µm, me ngā paninga ārai-whakaata (paninga AR), ka taea te whakapiki i te tuku toharite ki te 98%. Ka taea hoki e tātou te pani i te paninga waro rite-taimana (paninga DLC) te paninga pakari teitei rānei (paninga HD) ki te mata o te arotahi hei whakarato i te tiakitanga atu i te rakuraku me te pānga.
Te roanga ngaru o te infrarede hanga ana i ngā karāhe silicon porowhita me te aspheric kounga teitei ritenga. Ka taea e rātou te arotahi, te wehewehe rānei i te hihi mārama e tau mai ana kia tutuki ai ngā whakaritenga motuhake o te pūnaha infrared.
