A pūoko whakaahuahe taputapu e huri ana i ngā tohu mārama hei tohu hiko. I roto i tepūoko whakaahua haurua-haurua, ka uru te kaikawe whakaahua-whakaputa e whakaohokia ana e te photon taupatupatu ki te ara iahiko o waho i raro i te ngaohiko whakahāngai kua tukuna, ā, ka hangaia he iahiko whakaahua ka taea te ine. Ahakoa i te uruparenga mōrahi, ka taea e te photodiode pine te whakaputa i te takirua o ngā takirua irahiko-pōhao i te nuinga, he taputapu kāore he painga ā-roto. Mō te uruparenga nui ake, hete pūoro whakaahua horonga(apd) ka taea te whakamahi.
Ko te pānga whakanui o te apd ki te iahiko whakaahua e ahu mai ana i te pānga tukinga ionization. I raro i ētahi āhuatanga, ka taea e ngā irahiko me ngā kōhao tere te whiwhi pūngao nui hei tukinga ki te whatunga hei whakaputa i tētahi takirua hou o ngā takirua irahiko-kōhao. He tukanga mekameka tēnei, kia taea ai e te takirua o ngā takirua irahiko-kōhao i hangaia e te mimiti mārama te whakaputa i te maha o ngā takirua irahiko-kōhao me te hanga i tētahi iahiko whakaahua tuarua nui. Nō reira, he nui te urupare me te whiwhinga ā-roto o te apd, e whakapai ake ana i te ōwehenga tohu-ki-haruru o te taputapu. Ka whakamahia te apd i roto i ngā pūnaha whakawhitiwhiti muka whatu tawhiti, iti ake rānei, me ētahi atu herenga ki te mana whatu i whiwhihia. I tēnei wā, he maha ngā tohunga taputapu whatu e tino tumanako ana ki ngā tumanakohanga o te apd.
I whakawhanakehia motuhaketia e Rofea he pūoko whakaahua kua whakauruhia ki te photodiode me te ara iahiko whakakaha haruru iti, me te whakarato i ngā momo hua maha, mō ngā kaiwhakamahi rangahau pūtaiao. Ka whakaratohia he ratonga whakaritenga hua kounga teitei, he tautoko hangarau me te ratonga whai muri i te hoko watea. Kei roto i te raina hua o nāianei: he pūoko whakaahua tohu anaro me te whakakaha, he pūoko whakaahua ka taea te whakarite,pūoko whakaahua tere teitei, pūoko mākete hukarere (APD), pūoko taurite, me ētahi atu
