Anthu ambiri angadabwe chifukwa chake ma module a laser rangefinder amabwera m'ma wavelength osiyanasiyana. Zoona zake n'zakuti, kusiyanasiyana kwa ma wavelength kumachitika kuti pakhale kuyanjana pakati pa zosowa za ogwiritsa ntchito ndi zoletsa zaukadaulo. Ma wavelength a laser amakhudza mwachindunji magwiridwe antchito a makina, chitetezo, ndi mtengo. Nayi kufotokozera mwatsatanetsatane kwa zifukwa:
1. Zotsatira za Kutalika kwa Mafunde pa Makhalidwe Athupi a Kufufuza Malo Ozungulira
(1) Kuchepetsa Mlengalenga ndi Kugwira Ntchito kwa Kutumiza
Kutumiza kwa laser kumakhudzidwa ndi kuyamwa ndi kufalikira kwa mpweya mumlengalenga, zomwe zonsezi zimadalira kwambiri kutalika kwa mafunde.. Mafunde Afupi (monga, 532nm):ekukumana ndi kufalikira kwakukulu (rayleigh akubalalika). M'malo okhala ndi fumbi, chifunga, kapena mvula, kuchepa kwa kutentha kumakhala kwakukulu, zomwe zimapangitsa kuti zisagwiritsidwe ntchito patali. Ma Wavelengths a Mid-Range (monga, 808nm, 905nm):hAli ndi mphamvu zochepa zoyamwa ndi kufalikira mumlengalenga, zomwe zimapangitsa kuti zikhale zosankha zazikulu za rangefinder, makamaka zogwiritsidwa ntchito panja. Kutalika kwa Mafunde Aatali (monga, 1535nm, 1550nm):sYosavuta kuyamwa nthunzi ya madzi m'mikhalidwe ina koma imakhala ndi mphamvu zochepa zotayira komanso zokhazikika, yoyenera mtunda wautali komanso malo apadera.
(2) Makhalidwe Owunikira a Malo Olunjika
Kuwonekera kwa mafunde a laser pamalo omwe akufunidwa kumakhudza magwiridwe antchito a rangefinding.
Mwachidulewma avelengthspZimagwira ntchito bwino ndi zolinga zowunikira kwambiri koma zimakhala ndi kuwala kochepa pamalo amdima kapena ovuta.rmphamvuwma avelengthsoAmapereka kusinthasintha kwabwino pazipangizo zosiyanasiyana ndipo amapezeka kwambiri m'magawo ofufuza.pzimathandiza kuti malo otsetsereka azitha kulowa bwino, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito pojambula malo komanso zochitika zovuta.
2. Chitetezo cha Maso ndi Kusankha Kutalika kwa Mafunde
Diso la munthu limakhala losavuta kumva kuwala kooneka (400-700nm) ndi kuwala kofanana ndi infrared (700-1000nm). Kuwala kwa laser m'malo awa kumatha kuyang'ana pa retina ndikuwononga, zomwe zimapangitsa kuti pakhale kuwongolera mphamvu ndikuchepetsa zochitika zogwiritsidwa ntchito komanso mphamvu yotulutsa.wma avelengths (monga, 1535nm, 1550nm)ndi sPopeza mphamvu zawo zimatengedwa ndi cornea ndi lenzi, zimaletsa kuwonekera mwachindunji ku retina. Izi zimachepetsa kwambiri zoopsa zachitetezo, zomwe zimapangitsa kuti mafunde awa akhale ofunika kwambiri pakupeza malo ankhondo komanso akutali kwambiri.
3. Kuvuta kwaukadaulo ndi Mtengo
Kuvuta ndi mtengo wa ma module a laser rangefinder zimasiyana kwambiri kutengera kutalika kwa wavelength.
- 532nm (Malasi Obiriwira): Kawirikawiri amapangidwa ndi malasi a infrared omwe amawirikiza kawiri (1064nm). Njirayi imakhala ndi mphamvu zochepa, imafuna kutentha kwambiri, komanso imakhala ndi ndalama zambiri.
- 808nm, 905nm (Near-Infrared Lasers): Gwiritsani ntchito ukadaulo wa laser wa semiconductor okhwima, womwe umapereka magwiridwe antchito apamwamba komanso mtengo wotsika, zomwe zimapangitsa kuti zikhale zabwino kwambiri pazinthu zomwe ogula amagwiritsa ntchito.
- 1535nm, 1550nm (Malasi a Ulusi): Amafuna malasi apadera a ulusi ndi zowunikira zofanana (monga, InGaAs). Ma module awa ndi okwera mtengo kwambiri.
4. Zofunikira pakugwiritsa ntchito m'magawo osiyanasiyana
Kwa skutentha-dchithandizomkuchotsera ndalama, 532nm ndi 905nm ndi zosankha zabwino kwambiri. Ngakhale kuti zotsatira zobalalika zimakhala zazikulu pa nthawi yochepa ya mafunde, sizimakhudza kwambiri mtunda wautali. Kuphatikiza apo, ma laser a 905nm amapereka magwiridwe antchito ndi mtengo, zomwe zimakhala chisankho chodziwika bwino cha ma module a rangefinder.Kwa long-dchithandizomKuyesa: Mafunde a 1064nm ndi 1550nm ndi oyenera kwambiri, chifukwa mafunde aatali amasunga mphamvu ndikulowa bwino, abwino kwambiri pantchito zamafakitale ndi zankhondo zomwe zimafuna kuyeza kwakutali komanso kolondola kwambiri.Kwa high-lkuwala-ikusokonezaemalo okhala, Mafunde a 1550nm amagwira ntchito bwino kwambiri m'mikhalidwe yotereyi, chifukwa sakhudzidwa kwambiri ndi kusokonezedwa ndi dzuwa. Izi zimatsimikizira kuti pali chiŵerengero chachikulu cha ma signal-to-noise pansi pa kuwala kwamphamvu, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zida za radar zakunja ndi zowunikira.
Ndi kufotokozera kumeneku, tsopano muyenera kumvetsetsa bwino chifukwa chake ma module a laser rangefinder amabwera m'ma wavelength osiyanasiyana. Ngati mukufuna ma module a laser rangefinder kapena mukufuna kudziwa zambiri, musazengereze kulankhula nafe nthawi iliyonse!
