Mai nā modula ToF mua loa a hiki i ka lidar a hiki i ka DMS o kēia manawa, hoʻohana lākou a pau i ka hui kokoke-infrared:
Module TOF (850nm/940nm)
LiDAR (905nm/1550nm)
DMS/OMS（940nm）
I ka manawa like, ʻo ka puka aniani kahi ʻāpana o ke ala optical o ka mea ʻike / loaʻa. ʻO kāna hana nui ka pale ʻana i ka huahana i ka wā e hoʻouna ana i ka laser o kahi hawewe kikoʻī i hoʻokuʻu ʻia e ke kumu laser, a me ka hōʻiliʻili ʻana i nā nalu kukui i hōʻike ʻia ma ka puka makani.
Pono kēia puka makani i nā hana maʻamau:
1. ʻIke ʻia ʻeleʻele e uhi i nā mea optoelectronic ma hope o ka puka makani;
2. He haʻahaʻa ka hoʻohālikelike ʻana o ka ʻili o ka puka aniani a ʻaʻole ia e noʻonoʻo ʻia;
3. Loaʻa iā ia ka transmittance maikaʻi no ka hui laser. No ka laʻana, no ka mea maʻamau 905nm laser detector, hiki i ka transmittance o ka puka makani ma ka band 905nm ke piʻi aku ma mua o 95%.
4. E kānana i ke kukui ʻino, e hoʻomaikaʻi i ka ratio signal-to-noise o ka ʻōnaehana, a hoʻonui i ka hiki ke ʻike i ka lidar.
Eia nō naʻe, ʻo LiDAR a me DMS nā huahana automotive ʻelua, no laila pehea e hiki ai i nā huahana puka aniani ke hoʻokō i nā koi o ka hilinaʻi maikaʻi, ka transmittance kiʻekiʻe o ka pūnāwai kumu kukui, a ua lilo ka ʻeleʻele i mea pilikia.
01. ʻO ka hōʻuluʻulu o nā puka makani i kēia manawa ma ka mākeke
ʻEkolu mau ʻano nui:
ʻAno 1: Hana ʻia ka substrate me nā mea komo infrared
He ʻeleʻele kēia ʻano mea no ka mea hiki iā ia ke komo i ka mālamalama ʻike ʻia a hoʻouna i nā kaula kokoke-infrared, me ka transmittance o kahi o 90% (e like me 905nm i ka hui kokoke-infrared) a me ka reflectivity holoʻokoʻa ma kahi o 10%.
Hiki i kēia ʻano mea ke hoʻohana i nā substrates resin infrared i ʻike ʻia, e like me Bayer Makrolon PC 2405, akā ʻo ka substrate resin ka ikaika paʻa paʻa me ke kiʻi ʻoniʻoni, ʻaʻole hiki ke pale aku i nā hoʻokolohua hoʻāʻo kūlohelohe koʻikoʻi, ʻaʻole hiki ke hoʻopaʻa ʻia me ka ITO transparent Conductive film (hoʻohana ʻia no ka electrification a me ka defogging), no laila ʻaʻole i uhi ʻia kēia ʻano substrate i nā puka makani ʻaʻole i hoʻohana ʻia i ka radar.
Hiki iā ʻoe ke koho iā SCHOTT RG850 a i ʻole Kina HWB850 aniani ʻeleʻele, akā kiʻekiʻe ke kumukūʻai o kēia ʻano aniani ʻeleʻele. ʻO ka lawe ʻana i ke aniani HWB850 ma ke ʻano he laʻana, ʻoi aku kona kumukūʻai ma mua o 8 mau manawa o ke aniani optical maʻamau o ka nui like, a ʻo ka hapa nui o kēia ʻano huahana ʻaʻole hiki ke hele i ke kūlana ROHS a no laila ʻaʻole hiki ke hoʻohana ʻia i nā puka makani lidar i hana nui ʻia.
ʻAno 2: hoʻohana i ka inika transmissive infrared
ʻO kēia ʻano infrared penetrating ink e hoʻopili i ka mālamalama ʻike ʻia a hiki ke hoʻouna i nā kaula kokoke-infrared, me ka transmittance o kahi 80% a 90%, a haʻahaʻa ka pae transmittance holoʻokoʻa. Eia kekahi, ma hope o ka hui ʻana o ka ʻīnika me ka substrate optical, ʻaʻole hiki i ke kū ʻana o ke aniau ke hoʻokō i nā koi kūpaʻa kūwaho o ka automotive weather (e like me nā hoʻokolohua kiʻekiʻe wela), no laila hoʻohana nui ʻia nā infrared penetrating inks i nā huahana ʻē aʻe me nā koi haʻahaʻa haʻahaʻa e like me nā kelepona akamai a me nā kāmela infrared.
ʻAno 3: me ka hoʻohana ʻana i ka kānana optical uhi ʻeleʻele
ʻO ka kānana i uhi ʻia ʻeleʻele he kānana ia e hiki ke ālai i ka mālamalama ʻike ʻia a loaʻa ka transmittance kiʻekiʻe ma ka band NIR (e like me 905nm).
Hoʻolālā ʻia ka kānana ʻeleʻele me ka silicon hydride, silicon oxide a me nā mea ʻoniʻoni ʻoniʻoni ʻē aʻe, a ua hoʻomākaukau ʻia me ka ʻenehana magnetron sputtering. Hōʻike ʻia ia e ka hana paʻa a hilinaʻi a hiki ke hana nui ʻia. I kēia manawa, hoʻohana maʻamau nā kiʻi ʻoniʻoni ʻeleʻele ʻeleʻele i kahi ʻano like me ke kiʻi ʻoniʻoni māmā. Ma lalo o ke kaʻina hana kiʻiʻoniʻoni silicon hydride magnetron sputtering kiʻiʻoniʻoni, ʻo ka noʻonoʻo maʻamau e hōʻemi i ka absorption o ka silicon hydride, ʻoi aku ka nui o ka absorption o ka hui kokoke-infrared, e hōʻoia i kahi transmittance kiʻekiʻe ma ka band 905nm a i ʻole nā mea lidar e like me 1550nm.
Ka manawa hoʻouna: Nov-22-2024
