Ukuthelekisa okulula phakathi kwe-905nm kunye ne-1.5 ye-Lidar
Masenze lula kwaye sicacisa ukuthelekisa phakathi kwe-905nm kunye ne-1550 / 1535nm seidar serics:
| Inqaku | I-905nm Lidar | I-1550 / 1535nm Lidar |
| Ukhuseleko ngamehlo | - Sikhuselekile kodwa ngemida enamandla okhuseleko. | -Khuselekile kakhulu, ivumela ukusetyenziswa kwamandla okuphezulu. |
| Uluhlu | -Unokuba noluhlu olulinganiselweyo ngenxa yokhuseleko. | Uluhlu olude kuba unokusebenzisa amandla amaninzi ngokukhuselekileyo. |
| Intsebenzo kwimozulu | -Uchatshazelwe ngakumbi lilanga kunye nemozulu. | - Yenza ngcono kwimozulu embi kwaye ayichaphazeli ukukhanya kwelanga. |
| Iindleko | -Ixabiso eliphantsi, izinto zixhaphake ngakumbi. | -Beka kakhulu, sebenzisa izinto ezizodwa. |
| Eyona isetyenziselwa | -Izicelo ezinobuthathaka kakhulu ezineemfuno eziphakathi. | - Ukuphela kokuphela kuqhuba njengokuqhuba ngokuzenzekelayo kufuna ukubaleka kwaye ukhuseleko. |
Ukuthelekisa phakathi kwe-1550 / 1535nm kunye neenkqubo ezingama-905nm ibalaselisa izibonelelo ezininzi zokusebenzisa itekhnoloji yexesha elide (i-1550 / 1535n), ngakumbi ngokweemeko ezahlukeneyo zokusingqongileyo. Ezi zibonelelo zenza i-1550 / 1535nm yinkqubo efanelekileyo kakhulu kwizicelo ezifuna ukuchaneka okuphezulu kunye nokuthembeka, njengokuqhuba nge-autonomomous. Nantsi kujongwe okucacileyo kwezi zinto zilandelayo:
1. Ukuphucula ukhuseleko lwamehlo
Olona nyango lubaluleke kakhulu kwiinkqubo ezili-1550 / 1535nm ze-Lidar kukhuseleko lwazo lokhuseleko lwamehlo abantu. I-lavelengt ende iwele elona candelo lihle kakhulu yiCornea kunye ne-lens yeliso, ukuthintela ukukhanya ekufikeleleni kwi-retina ebuthathaka. Olu phawu luvumela ezi nkqubo ukuba zisebenze ngamanqanaba aphezulu ombane ngelixa uhlala ngaphakathi kwemida ekhuselekileyo, eyenza ukuba azilungiselele iinkqubo ezifuna ukusebenza kakuhle kwe-idar.
I-2. Uluhlu lwexesha elide
Enkosi ekukhuliseni ngamandla aphezulu ngokukhuselekileyo, i-1550 / 1535nm i-lidar ye-Lidar inokufezekisa uluhlu olude. Oku kubalulekile kwizithuthi ezizenzayo, ezifuna ukufumana izinto ukusuka kumgama ukwenzela ukwenza izigqibo ngexesha elifanelekileyo. Uluhlu olongezelelekileyo olunikezwe ngala maWaveleths luqinisekisa ukuba nezakhono zokulindela kunye nokuphendula, ukuphucula ukhuseleko kunye nokusebenza ngokufezekileyo kweenkqubo zokuhamba ezizenzekelayo.
3. Ukuphuculwa kwentsebenzo kwiimeko ezimbi zemozulu
Iinkqubo ze-lidar ezisebenza ngo-1550 / 1535nm Wavelengt zibonisa ukusebenza kakuhle kwiimeko zemozulu ezimbi, njengenkungu, imvula, okanye uthuli. La magqabi amade angena kwi-themospic amasuntswana ngakumbi kunamaza amafutshane amafutshane, agcina ukusebenza kunye nokuthembeka xa ukubonakala kuhlwempuzekile. Oku kubanakho kubalulekile ekusebenzeni okungaguqukiyo kweenkqubo zeZenzo, nokuba zinjani na iimeko zokusingqongileyo.
I-4. Ukunciphisa ukuphazamiseka ukusuka elangeni kunye neminye imithombo yokukhanya
Elinye i-1550 / 1535nm Lidar yimvakalelo yokuphazamiseka ekuphazelisweni ukusuka ekuphazamiseni okukukhanya, kubandakanya ukukhanya kwelanga. Amaza amasebe athile asetyenziswa kwezi nkqubo angaqhelekanga kwimithombo yokukhanya yendalo neyokwakheka, enciphisa umngcipheko wokuphazamiseka onokuchaphazela ukuchaneka kwemephu yendalo. Eli nqaku libaluleke ngokukodwa kwiimeko apho ukubonwa ngokuchanekileyo kunye nemephu kubaluleke kakhulu.
5. Ukungena kwempahla
Ngelixa ingeyiyo ekuqwalaselweni eziPhambili kuzo zonke izicelo, amaza amatsha e-1550 / 1535nm anokubonelela ngeendlela ezahlukeneyo zezinto ezisetyenziswayo kwiinkcukacha okanye kwindawo ethile (ukuya kuthi ga kwinqanaba elithile) kunokuba luncedo.
Ngaphandle kwezi zinto ziluncedo, ukhetho oluphakathi kwe-1550 / 1535nm kunye neenkqubo ezingama-905nm zikwabandakanya ukuqwalaselwa kweendleko kunye neemfuno zesicelo. Ngelixa iinkqubo ze-1550 / 1535nm zibonelela ngentsebenzo ePhakamileyo kunye nokhuseleko, zibiza kakhulu ngenxa yobunzima kunye nemveliso esezantsi yemveliso yamacandelo abo. Ke ngoko, isigqibo sokusebenzisa itekhnoloji ye-1550 / 1535nm ihlala ixhomekeke kwiimfuno ezithile zesicelo, kubandakanya uluhlu olufunekayo, ukuqwalaselwa kwezokhuseleko, kunye nezithintelo zohlahlo -daniso, kunye nezithintelo zohlahlo -daniso, kunye nezithintelo zohlahlo -daniso, kunye neemeko zohlahlo -daniso, kunye nezithintelo zohlahlo -daniso.
