Uthelekiso phakathi kweenkqubo ze-LiDAR ze-1550/1535nm kunye ne-905nm lubonisa iingenelo ezininzi zokusebenzisa itekhnoloji ye-long wavelength (1550/1535nm), ngakumbi ngokubhekiselele kukhuseleko, ububanzi, kunye nokusebenza kwiimeko ezahlukeneyo zendalo. Ezi ngenelo zenza iinkqubo ze-LiDAR ze-1550/1535nm zifaneleke ngokukodwa kwizicelo ezifuna ukuchaneka okuphezulu kunye nokuthembeka, njengokuqhuba ngokuzimela. Nantsi inkcazo eneenkcukacha zezi ngenelo:
1. Ukhuseleko lwamehlo oluphuculweyo
Eyona nzuzo ibalulekileyo yeenkqubo ze-LiDAR ze-1550/1535nm kukhuseleko lwazo oluphuculweyo emehlweni abantu. Amaza amade awela kudidi olufunxwa ngokufanelekileyo yi-cornea kunye nelensi yeliso, nto leyo ethintela ukukhanya ekufikeleleni kwi-retina enobuthathaka. Olu phawu luvumela ezi nkqubo ukuba zisebenze kumanqanaba aphezulu amandla ngelixa zihlala ngaphakathi kwemida yokuvezwa ekhuselekileyo, nto leyo ezenza zilungele ukusetyenziswa kweenkqubo ze-LiDAR ezisebenza kakuhle ngaphandle kokubeka emngciphekweni ukhuseleko lwabantu.
2. Uluhlu olude lokuFumanisa
Ngenxa yokukwazi ukukhupha amandla aphezulu ngokukhuselekileyo, iinkqubo ze-LiDAR ze-1550/1535nm zinokufikelela kuluhlu olude lokubona. Oku kubalulekile kwizithuthi ezizimeleyo, ezifuna ukubona izinto zikude ukuze zenze izigqibo ngexesha elifanelekileyo. Uluhlu olude olubonelelwa ngala maza okukhanya luqinisekisa ulindelo olungcono kunye namandla okuphendula, nto leyo ephucula ukhuseleko kunye nokusebenza kakuhle kweenkqubo zokuhamba ezizimeleyo.
3. Ukusebenza Okuphuculweyo Kwiimeko Zemozulu Ezimbi
Iinkqubo zeLiDAR ezisebenza kumaza obude obuyi-1550/1535nm zibonisa ukusebenza ngcono kwiimeko zemozulu ezimbi, ezifana nenkungu, imvula, okanye uthuli. Ezi maza obude obude zinokungena kumasuntswana omoya ngokufanelekileyo kunee-wavelength ezimfutshane, zigcine ukusebenza kunye nokuthembeka xa ukubonakala kungabonakali kakuhle. Olu buchule lubalulekile ekusebenzeni rhoqo kweenkqubo ezizimeleyo, nokuba iimeko zendalo zinjani na.
4. Ukuphazamiseka okuncitshisiweyo okuvela ekukhanyeni kwelanga nakwezinye iindawo zokukhanya
Enye inzuzo ye-1550/1535nm LiDAR kukuba ibuthathaka kakhulu ekuphazamisekeni kokukhanya okukufutshane, kuquka nokukhanya kwelanga. Amaza athile asetyenziswa zezi nkqubo awaxhaphakanga kakhulu kwimithombo yokukhanya yendalo neyenziweyo, nto leyo enciphisa umngcipheko wokuphazamiseka okunokuchaphazela ukuchaneka kwemephu yokusingqongileyo yeLiDAR. Olu phawu lubaluleke kakhulu kwiimeko apho ukufunyanwa ngokuchanekileyo kunye nemephu kubaluleke kakhulu.
5. Ukungena kwezinto
Nangona kungengombandela ophambili kuzo zonke izicelo, ubude be-wavelengths beenkqubo ze-LiDAR ze-1550/1535nm bunokubonelela ngokusebenzisana okwahlukileyo kancinci nezixhobo ezithile, okunokubonelela ngeenzuzo kwiimeko ezithile zokusetyenziswa apho ukukhanya okungenayo ngokusebenzisa iinxalenye okanye umphezulu (ukuya kwinqanaba elithile) kunokuba luncedo.
Nangona ezi zibonelelo zinjalo, ukhetho phakathi kweenkqubo ze-LiDAR ze-1550/1535nm kunye ne-905nm lukwabandakanya ukuqwalaselwa kweendleko kunye neemfuno zokusetyenziswa. Ngelixa iinkqubo ze-1550/1535nm zibonelela ngokusebenza okuphezulu kunye nokhuseleko, zihlala zibiza kakhulu ngenxa yobunzima kunye nomthamo omncinci wemveliso yamacandelo azo. Ke ngoko, isigqibo sokusebenzisa itekhnoloji ye-LiDAR ye-1550/1535nm sihlala sixhomekeke kwiimfuno ezithile zokusetyenziswa, kubandakanya uluhlu olufunekayo, ukuqwalaselwa kokhuseleko, iimeko zokusingqongileyo, kunye nemida yohlahlo-lwabiwo mali.
