Lidar chips yog cov khoom tseem ceeb hauv txoj kev loj hlob ntawm cov tsheb tshiab thiab cov tsheb ntse. Tam sim no, tag nrho cov khoom-lub xeev OPA 2D LiDAR nti tau ua tiav kev sim thiab kev txhim kho ntawm OPA 3D LiDAR nti yog nyob rau hauv qhov sib npaug.
Lidar zoo li tib neeg lub qhov muag, ntxiv rau qhov tsim nyog rau kev txhim kho lub zog tshiab tsheb thiab kev lag luam tsheb ntse, nws kuj tseem muaj cov ntawv thov tseem ceeb hauv lwm cov kev lag luam, thiab yog tias nws tuaj yeem ua tau zoo dua industrialised, nws yuav tsav txoj kev loj hlob ntxiv. opto-electronic teb.
Txoj kev loj hlob ntawm nti-theem photonics yog fueling txoj kev loj hlob ntawm kev txawj ntse. Lub peev xwm rau kev sib txuas ntawm photonics thiab kev txawj ntse txawj ntse yog qhov loj, thiab cov cuab yeej txawj ntse raws li kev txawj ntse thiab cov tshuab, xws li cov neeg hlau, kev tsav tsheb tsis muaj zog, tsheb tsis muaj tsheb thiab drones, yuav vam khom rau optoelectronic chips xws li LiDAR kom ua tiav kev txawj ntse thiab kev ua tau zoo. All-solid-state optical phased array (OPA) LIDAR technology yog ib hom tshiab ntawm waveguide tswj beam taw tes radar thev naus laus zis. Raws li Chen Haitao, tus thawj coj ntawm Yangzhou Qunfa, tam sim no muaj plaub lub ntsiab LIDAR thev naus laus zis hauv kev ua lag luam.
I. Mechanical LIDAR, uas muaj qhov zoo ntawm cov thev naus laus zis yog qhov paub tab thiab tau mus txog ntau lawm, tab sis kuj muaj qhov tsis zoo ntawm qhov loj, tus nqi qis thiab tsis ruaj khov thiab ruaj khov vim muaj ntau cov khoom siv tshuab. .
II. MEMS LIDAR thev naus laus zis, tseem hu ua yias-mechanical LIDAR, muaj qhov zoo ntawm qhov me me, cov qauv yooj yim thiab txo tus nqi tseem ceeb piv rau cov tshuab radars, tab sis nyuaj rau kev sib sau ua ke, muaj lub neej luv luv, nyuaj rau cov khoom loj thiab muaj. txwv scanning kaum.
III. Flash LIDAR thev naus laus zis, vim tias nws tsis muaj cov cuab yeej ntsuas hluav taws xob ntawm lub teeb nrawm, muaj lub zog ruaj khov nrog lub zog ua kom muaj zog, tab sis nws siv zog ntau dua thiab ua rau muaj kev nyab xeeb rau tus neeg teb xov tooj, yog li feem ntau Flash LIDAR tuaj yeem tsuas siv los ua tus sensor thib ob thiab tsis yog thawj sensor.
IV. OPA LIDAR thev naus laus zis, piv rau lwm yam peb radar khoom, OPA LIDAR tsis tas yuav tsum muaj kev sib hloov tshuab kom ua tiav qhov kev soj ntsuam ntawm cov nqaj hauv qhov chaw, nws cov lus teb ceev, yooj, siab raug, tsis tshua muaj nqi, me me, tag nrho cov khoom hauv lub xeev ntawm kev soj ntsuam. Lub hom phiaj ntawm kev ua haujlwm siab ceev, synchronous taug qab ntawm ntau lub hom phiaj thiab lwm yam tau hais txog qhov pom tseeb zoo, yog li nyob rau hauv kev tsav tsheb tsis muaj neeg tsav tsheb, neeg hlau, kev ruaj ntseg ntse thiab lwm yam ntawm ntau yam kev thov kev cia siab, thiab tam sim no tau lees paub tias yog ib qho ntawm cov Kev txhim kho qhov kawg ntawm LIDAR thev naus laus zis.
