M256 uncooled thermal imaging module
♦ Hoʻolauna
Hoʻokumu ʻia ka module thermal imaging ma ka ceramic packaging uncooled vanadium oxide infrared detector e hoʻomohala i kahi huahana infrared thermal imaging kiʻekiʻe, hoʻohana nā huahana i ka pānaehana puka kikohoʻe parallel, waiwai nui ka interface, hiki ke hoʻololi i kahi ʻano o ka papa hana naʻauao, me ka hana kiʻekiʻe a me ka mana haʻahaʻa. ka hoʻohana ʻana, ka leo liʻiliʻi, maʻalahi i nā ʻano o ka hoʻohui hoʻomohala ʻana, hiki ke hoʻokō i ka noi ʻana o nā ʻano like ʻole o ke ana wela infrared o ke koi hoʻomohala lua.
Nā hiʻohiʻona huahana
- He liʻiliʻi ka nui o ka huahana a maʻalahi ke hoʻohui;
- Hoʻohana ʻia ka FPC interface, kahi waiwai i nā interface a maʻalahi hoʻi e hoʻopili me nā pae ʻē aʻe;
- Haʻahaʻa mana hoʻohana;
- Kiʻi kiʻi kiʻekiʻe;
- Ana wela pololei;
- kaʻikeʻikepili maʻamau, kākoʻo i ka hoʻomohala lua, hoʻohui maʻalahi, kākoʻo i ka loaʻa ʻana i nā ʻano o ka papa hana naʻauao.
