Ukusuka kwiimodyuli zokuqala ze-ToF ukuya kwi-lidar ukuya kwi-DMS yangoku, bonke basebenzisa ibhendi ekufutshane ne-infrared:
Imodyuli ye-TOF (850nm/940nm)
I-LiDAR (905nm/1550nm)
DMS/OMS (940nm)
Ngexesha elifanayo, ifestile ye-optical iyingxenye yendlela ye-optical ye-detector / receiver. Umsebenzi wayo ophambili kukukhusela imveliso ngelixa uhambisa i-laser ye-wavelength ethile ekhutshwe ngumthombo we-laser, kunye nokuqokelela amaza okukhanya ahambelanayo abonakalisiweyo ngefestile.
Le festile kufuneka ibenemisebenzi esisiseko ilandelayo:
1. Kubonakala kumnyama ngokubonakalayo ukugquma izixhobo ze-optoelectronic emva kwefestile;
2. I-reflectivity jikelele yomphezulu wefestile ye-optical iphantsi kwaye ayiyi kubangela ukubonakaliswa okucacileyo;
3. Inokuhanjiswa kakuhle kwibhendi yelaser. Ngokomzekelo, kwi-905nm laser detector eqhelekileyo, ukuhanjiswa kwefestile kwi-905nm band kunokufikelela ngaphezu kwe-95%.
4. Hlunga ukukhanya okuyingozi, uphucule umlinganiselo wesignali-kwingxolo yenkqubo, kwaye uphucule ukukwazi ukubonwa kwe-lidar.
Nangona kunjalo, i-LiDAR kunye ne-DMS zombini imveliso yeemoto, ngoko ke ukuba iimveliso zefestile zinokuhlangabezana njani neemfuno zokuthembeka okulungileyo, ukuhanjiswa okuphezulu kwebhendi yomthombo wokukhanya, kunye nokubonakala komnyama kuye kwaba yingxaki.
01. Isishwankathelo sezisombululo zefestile ngoku kwimarike
Kukho iintlobo ezintathu ikakhulu:
Uhlobo loku-1: I-substrate yenziwe nge-infrared material yokungena
Olu hlobo lwempahla lumnyama kuba luyakwazi ukufunxa ukukhanya okubonakalayo kwaye ludlulise iibhendi ezikufutshane ne-infrared, kunye nokuhanjiswa malunga ne-90% (njenge-905nm kwibhendi ekufutshane ne-infrared) kunye nokubonakala okupheleleyo malunga ne-10%.
Olu hlobo lwezinto eziphathekayo lunokusebenzisa i-infrared transparent resin substrates, njenge-Bayer Makrolon PC 2405, kodwa i-resin substrate inamandla okubambisana kunye nefilimu ebonakalayo, ayikwazi ukumelana novavanyo olunzima lokusingqongileyo, kwaye ayikwazi ukufakwa ngefilimu ethembekileyo ye-ITO ecacileyo ye-Conductive (esetyenziselwa umbane kunye nokuchithwa), ngoko ke olu hlobo luhlala lusetyenziswa kwiifestile ze-substrate kunye ne-substrate. ayifuni ukufudumeza.
Unokukhetha kwakhona i-SCHOTT RG850 okanye i-Chinese HWB850 yeglasi emnyama, kodwa ixabiso loluhlobo lweglasi emnyama liphezulu. Ukuthatha iglasi ye-HWB850 njengomzekelo, iindleko zayo zingaphezu kwe-8 yeglasi yeglasi eqhelekileyo yobukhulu obufanayo, kwaye ininzi yolu hlobo lwemveliso ayikwazi ukudlula umgangatho we-ROHS kwaye ngoko ayikwazi ukusetyenziswa kwiifestile ze-lidar eziveliswe ngobuninzi.
Uhlobo lwesi-2: usebenzisa i-infrared transmissive inki
Olu hlobo lwe-infrared ye-infrared inki ithatha ukukhanya okubonakalayo kwaye iyakwazi ukuhambisa iibhendi ezikufutshane ne-infrared, kunye nokuhanjiswa malunga ne-80% ukuya kwi-90%, kwaye inqanaba lokuhambisa liphantsi. Ngaphezu koko, emva kokuba i-inki idityaniswe ne-optical substrate, ukuxhathisa kwemozulu akukwazi ukudlula iimfuno ezingqongqo zokuxhathisa imozulu yemoto (ezifana novavanyo lobushushu obuphezulu), ngoko ke ii-infrared ezingenayo i-infrared zisetyenziswa kakhulu kwezinye iimveliso ezineemfuno zokuxhathisa imozulu ephantsi ezifana neefowuni ze-smart kunye neekhamera ze-infrared.
Uhlobo lwesi-3: usebenzisa isihluzo esibonakalayo esimnyama
Isihluzo esimnyama esigqunyiweyo sisihluzo esinokuvala ukukhanya okubonakalayo kwaye sinokuhanjiswa okuphezulu kwi-NIR band (efana ne-905nm).
Isihluzi esimnyama esigqunyiweyo siyilwe ngesilicon hydride, isilicon oxide kunye nezinye izixhobo zefilimu ezibhityileyo, kwaye ilungiswa kusetyenziswa itekhnoloji ye-magnetron sputtering. Ibonakaliswa ngokusebenza okuzinzile kunye nokuthembekileyo kwaye inokuveliswa ngobuninzi. Okwangoku, iifilimu zokucoca ezimnyama eziqhelekileyo ngokuqhelekileyo zamkela isakhiwo esifana nefilimu yokucima ukukhanya. Ngaphantsi kwenkqubo yesiqhelo yesilicon hydride magnetron sputtering film forming process, ukuqwalaselwa okuqhelekileyo kukunciphisa ukufunxwa kwesilicon hydride, ngakumbi ukufunxwa kwebhendi ekufutshane ne-infrared, ukuqinisekisa ukuhanjiswa okuphezulu kwi-905nm band okanye ezinye iibhendi zelidar ezifana ne-1550nm.
