Ma ke kokoke i ka manawa kokoke (Swir),ʻoi aku ka nui o ka nānāʻana i nā mea kiʻekiʻe a Avalanches Avalanches Avalanches Agalec Eia nō naʻe,ʻo ka mea i hoʻopiliʻia ma kahi o Avalanched i kēia manawa Inalas), hopena i kahi hōʻemi nui i ka noʻonoʻoʻana o ka mea pili. I nā makahiki he nui nā mea noiʻi he nui eʻimi ana i nā mea hou semiconducor e like me ka megtonectrocess off and ultra-love

ʻO ka loiloi RONOVATE 1550 NM Avalanche Photodoido e kōkua i ka hoʻomohalaʻana i nā'ōnaehana lidar

He hui o nā mea noiʻi i ka United Kingdoms a meʻAmelika Hui PūʻIa a hiki i ka manawa mua e hana maikaʻi i ka manawa mua i kūkuluʻia i kahi mea hou loa 1550 NM APD (Avalanche photodettector), he snowthust e hoʻohiki nui e hoʻomaikaʻi nui i ka hana o nā'ōnaehana ludar a me nā noi'ē aʻe.

Hāʻawi nā mea hou i nā pono kālā

ʻO keʻano nui o kēia noiʻiʻo ia ka hoʻohanaʻoleʻana o nāʻano meaʻole. ʻO nā mea noiʻi i kohoʻia e like me ka waihoʻana o ka waihoʻana a me Algassb e like me ka papa nui. ʻOkoʻa kēia hoʻolālā mai nā intaitional intaas / inp a lawe i nā pono nui:

1.GASSB ABSORPERS: Ua loaʻa iā Gassb i kahiʻano likeʻole i ka nui o ka nohoʻana, a me ka hoʻomaʻamaʻaʻana i ka wikiwiki a me ka hoʻopauʻana i ka wikiwiki a me ka hoʻoukaʻana i ka wikiwiki.

2.alGassb Passer eyener:ʻo Algassb e hoʻomoʻa i ka papa hana nui loa i ka hana kuʻuna a me ka i loko o ka hana ma ka hana. Ua hōʻike nuiʻia ia i ka loaʻa kālā kiʻekiʻe ma ka mahana o ka lumi, kiʻekiʻe o ka bandwidth kiʻekiʻe a me ka ultra-haʻahaʻa.

Me nā hōʻike hana maikaʻi loa

Ka mea houAPd photodetector(Avanche PhotoDode PhotoDector) Hāʻawi i nā hoʻomaikaʻi nui i nā metric:

1. Ua loaʻa i ka waiwai kiʻekiʻe:ʻO ka loaʻaʻana o ka loaʻaʻana o 278 i ka mahana kiʻekiʻe, a ua hoʻonuiʻiaʻo Kauka Jin Jin Xanoo

2. E nānā i nā leo haʻahaʻa haʻahaʻa: hōʻike i nā leo nui loa (F <3, loaʻa iā M = 70, loaʻa iā M = 100).
