HAMAMATSU, Iapana, ʻAuk. 25, 2021 - Hamamatsu Photonics a me ka National Institute of Advanced Industrial Science and Technology (AIST) ma Tokyo i laulima ʻia ma kahi ʻōnaehana optika āpau, lawe ʻōnaehana nānā kinoea no ka wānana ʻana i nā luaʻi pele me kahi kiʻekiʻe o ka ʻike. Ma waho aʻe o ka hāʻawi ʻana i kahi nānā paʻa, mālama wā lōʻihi o nā ʻenekini lua pele kokoke i nā lua pele, hiki ke hoʻohana ʻia ka mea hoʻoliʻiliʻi lawe lima e ʻike i nā kahe kinoea ʻawahia i nā mea kanu kemika a me nā ana a me nā ana o ka lewa.

Aia i loko o ka ʻōnaehana kahi miniaturized, wavelength-swept kuantum cascade laser (QCL) i hoʻomohala ʻia e Hamamatsu. Ma kahi o 1 / 150th ka nui o nā QCL i hala aku nei, ʻo ka laser ka QCL o ka nalu lōʻihi liʻiliʻi o ka honua. ʻO ka ʻōnaehana kalaiwa no ka ʻōnaehana mālama kinoea, hoʻomohala ʻia e AIST, e ʻae i ka QCL liʻiliʻi e kau ʻia i loko o nā māmā, nā mea hoʻoliʻiliʻi lawe lima hiki ke hāpai ʻia ma nā wahi āpau.
ʻO ka QCL hawewe-nalu liʻiliʻi loa o ka honua ʻo 1 / 150th wale nō ka nui o nā QCL huluhulu lōʻihi i hala. Ma ka ʻoluʻolu a Hamamatsu Photonics KK a me New Energy and Industrial Technology Development Organization (NEDO).
Leveraging ko Hamamatsu ʻōnaehana microelectromekanical (MEMS) ʻenehana hou, hoʻopau hou nā mea hoʻomohala i ka papa manamana MEMS o QCL, e hoʻoliʻiliʻi ana ma kahi o 1/10 i ka nui o nā gratings maʻamau. Ua hoʻohana ka kime i kahi magnet liʻiliʻi i hoʻonohonoho ʻia e hōʻemi i kahi kūpono ʻole, a hōʻiliʻili pololei i nā ʻāpana ʻē aʻe me ka pololei i lalo i nā ʻāpana o 0.1 μm. ʻO nā ana kūwaho o ka QCL ʻo 13 × 30 × 13 mm (W × D × H).

Hoʻohana nā QCL i ka nalu lōʻihi i ka papa manamana diffraction MEMS e hoʻopuehu, hōʻike, a hoʻopuka i ke kukui uila waena i ka neʻe wikiwiki ʻana i ka nalu. Hiki ke hoʻopili ʻia ka nalu nalu a Hamamatsu QCL ma ka pae nalu o 7 a 8 μm. Hoʻokomo maʻalahi ʻia kēia pae e nā kinoea SO2 a me H2S i manaʻo ʻia he wānana mua i ka pele pele hiki.

No ka hoʻokō ʻana i kahi nalu lōʻihi i hiki ke hoʻopaʻa ʻia, ua hoʻohana nā mea noiʻi i kahi ʻenehana hoʻolālā pono e hoʻokumu ʻia i ka hopena o ka nui. No ka papa kukui uila o ka mea QCL, ua hoʻohana lākou i kahi hoʻolālā pālua-kiʻina kiʻekiʻe i kū i ka anti-cross.

Ke hoʻohui ʻia ka QCL nalu lōʻihi-lōʻihi me ka ʻōnaehana hoʻokele i hoʻomohala ʻia e AIST, hiki iā ia ke hoʻokō i kahi wikiwiki nalu lōʻihi e loaʻa ai ka laulā waena infrared light i loko o 20 ms. ʻO ka loaʻa wikiwiki ʻana o ka laulaha o ka QCL e kōkua ai i nā anamanaʻo o nā hanana transient e loli wikiwiki i ka hala o ka manawa. ʻO ka hoʻonā spectral o ka QCL ma kahi o 15 nm, a ʻo kona palena kiʻekiʻe loa e like me 150 mW.

I kēia manawa, ua hoʻohana ka hapa nui o nā mea kālailai e ʻike a ana i nā kinoea lua pele i ka manawa maoli i loaʻa i nā mea uila electrochemical. Hoʻopili wikiwiki nā uila uila i kēia mau mea ʻike - a me ka hana o ka mea kālailai - ma muli o ke kū mau ʻana i ke kinoea ʻona. Hoʻohana nā mea ʻanekini aniani āpau i kahi kumu kukui ola lōʻihi a koi i ka mālama liʻiliʻi, akā hiki i ke kumu kukui ʻōnohi ke lawe i kahi ākea. ʻO ka nui o kēia mau loiloi e paʻakikī iā lākou e hoʻouka ma kahi o nā lua pele.

ʻO ka ʻōnaehana kamepiula lua pele hanauna hou, i hoʻolako ʻia me ka QCL nalu lōʻihi lōʻihi, e hāʻawi i nā volcanologists me kahi ʻōnaehana opua, compact, portable i ʻike nui ʻia a mālama maʻalahi hoʻi. ʻO nā kānaka noiʻi ma Hamamatsu a me kā lākou mau hoapili ma AIST a me ka New Energy and Industrial Technology Development Organization (NEDO), ka mea i kākoʻo i ka papahana, e hoʻomau i ka noiʻi ʻana i nā ala e hoʻonui ai i ka noʻonoʻo o ka mea kālailai a hoʻemi i ka mālama ʻana.

Ke hoʻolālā nei ka kime i nā nānā multipoint e hoʻāʻo a hōʻike i ka mea hoʻoliʻiliʻi lawe lima. Hoʻolālā ʻia nā huahana e hoʻohana ana i ka QCL wavelength-swept a me nā huakaʻi kalaiwa me nā kiʻi uila o Hamamatsu no ka hoʻokuʻu ʻia ma 2022.
