Kuva kuri moderi ya mbere ya ToF kugeza lidar kugeza kuri DMS y'ubu, bose bakoresha hafi-ya-infragre band:
Module ya TOF (850nm / 940nm)
LiDAR (905nm / 1550nm)
DMS / OMS （940nm）
Mugihe kimwe, idirishya rya optique ni igice cyinzira ya optique ya detector / yakira. Igikorwa cyacyo nyamukuru ni ukurinda ibicuruzwa mugihe cyohereza lazeri yuburebure bwihariye bwasohowe nisoko ya laser, no gukusanya urumuri rwerekanwe rwerekanwe mumadirishya.
Idirishya rigomba kugira ibikorwa byibanze bikurikira:
1. Biboneka bigaragara umukara kugirango utwikire ibikoresho bya optoelectronic inyuma yidirishya;
2. Ubuso rusange bwerekana neza idirishya rya optique ni rito kandi ntabwo bizatera kugaragara neza;
3. Ifite imiyoboro myiza ya bande ya laser. Kurugero, kubisanzwe 905nm ya laser detector, ihererekanyabubasha ryidirishya mumurongo wa 905nm rishobora kugera kuri 95%.
4. Shungura urumuri rwangiza, utezimbere ibimenyetso-by-urusaku rwa sisitemu, kandi wongere ubushobozi bwo kumenya lidar.
Nyamara, LiDAR na DMS byombi nibicuruzwa bitwara ibinyabiziga, kuburyo burya ibicuruzwa byidirishya bishobora kuzuza ibisabwa byokwizerwa neza, guhererekanya kwinshi kwumucyo utanga urumuri, no kugaragara kwirabura byabaye ikibazo.
01 Incamake y'ibisubizo by'idirishya kurubu ku isoko
Hariho ubwoko butatu:
Ubwoko bwa 1: Substrate ikozwe mubintu bitagira ingano
Ubu bwoko bwibikoresho ni umukara kuko bushobora gukurura urumuri rugaragara no kohereza hafi ya-infrarafarike, hamwe nogukwirakwiza hafi 90% (nka 905nm muri bande yegereye-infragre) hamwe no kwerekana muri rusange hafi 10%.
Ubu bwoko bwibikoresho bushobora gukoresha insina zidafite ubuziranenge cyane, nka Bayer Makrolon PC 2405, ariko insina ya resin ifite imbaraga nke zo guhuza hamwe na firime optique, ntishobora kwihanganira igeragezwa rikaze ry’ibidukikije, kandi ntishobora gushyirwaho na firime yizewe cyane ya ITO ikora neza (ikoreshwa mu gukwirakwiza amashanyarazi no gukoresha defogge), bityo ubu bwoko bwa substrate bukaba budashyirwa mu majwi kandi budakoreshwa mu idirishya ridakoreshwa mu idirishya.
Urashobora kandi guhitamo SCHOTT RG850 cyangwa Ubushinwa HWB850 ikirahure cyirabura, ariko ikiguzi cyubu bwoko bwikirahure cyirabura ni kinini. Dufashe nk'ikirahuri cya HWB850, igiciro cyacyo kirenze inshuro 8 icy'ikirahuri gisanzwe cya optique kingana, kandi ibyinshi muri ubu bwoko bwibicuruzwa ntibishobora kurenga igipimo cya ROHS bityo ntibishobora gukoreshwa kumadirishya yakozwe na lidar.
Ubwoko bwa 2: ukoresheje wino ya infragre
Ubu bwoko bwa infragre yinjira muri wino ikurura urumuri rugaragara kandi irashobora kwanduza hafi ya-infrarafarike, hamwe na 80% kugeza 90%, kandi muri rusange urwego rwohereza ruri hasi. Byongeye kandi, nyuma yuko wino ihujwe na optique ya optique, guhangana nikirere ntibishobora kurenga ibyangombwa bikenerwa n’imiterere y’ibinyabiziga (nko gupima ubushyuhe bwo hejuru), bityo wino ya infragre yinjira cyane ikoreshwa mubindi bicuruzwa bifite ibyifuzo bike byo guhangana n’ikirere nka terefone zifite ubwenge na kamera za infragre.
Ubwoko bwa 3: ukoresheje umukara utwikiriye optiki muyunguruzi
Akayunguruzo kirabura kayunguruzo ni akayunguruzo gashobora guhagarika urumuri rugaragara kandi rufite itumanaho ryinshi kuri bande ya NIR (nka 905nm).
Akayunguruzo kirabura gashushanyijeho hydride ya silicon, okiside ya silicon nibindi bikoresho bya firime yoroheje, kandi byateguwe hifashishijwe ikoranabuhanga rya magnetron. Irangwa nimikorere ihamye kandi yizewe kandi irashobora kubyara umusaruro. Kugeza ubu, filime isanzwe yirabura ya optique iyungurura muri rusange ifata imiterere isa na firime yoroheje. Muburyo busanzwe bwa silicon hydride magnetron sputtering firime yo gukora, ibisanzwe bitekerezwaho ni ukugabanya kwinjiza hydride ya silicon, cyane cyane iyinjizwa ryumurongo uri hafi ya infragre, kugirango habeho kwanduza cyane mumatsinda ya 905nm cyangwa andi matsinda ya lidar nka 1550nm.
