Bhalisela imidiya yethu yezenhlalo yokuthumela okusheshayo
Ukuqhathanisa okulula phakathi kuka-905NM kanye ne-1.5μm Lidar
Masenze lula futhi sicacise ukuqhathanisa phakathi kwama-905nm nezinhlelo eziyi-1550 / 1535nm:
| Ubuso | 905nm lidar | I-1550 / 1535nm lidar |
| Ukuphepha kwamehlo | - Kuphephile kodwa ngemikhawulo emandleni okuphepha. | - Kuphephile kakhulu, kuvumela ukusetshenziswa kwamandla okuphezulu. |
| Ukuqhelelana | - Ungaba nebanga elilinganiselwe ngenxa yokuphepha. | - Ibanga elide ngoba lingasebenzisa amandla amaningi ngokuphepha. |
| Ukusebenza kwesimo sezulu | - Ochungechungezeka yilanga kanye nesimo sezulu. | - Ukwenza kangcono esimweni sezulu esibi futhi kuthinteka kancane elangeni. |
| Khokhisa | - I-CHEAPER, izakhi zivame kakhulu. | - Iyabiza kakhulu, isebenzisa izinto ezikhethekile. |
| Isetshenziselwa kangcono | - Izicelo ezibucayi zezindleko ezinezidingo ezilinganiselayo. | - Ukudla okuphezulu okuphezulu njengokushayela okuzimele kudinga ibanga elide nokuphepha. |
Ukuqhathanisa phakathi kuka-1550 / 1535nm nezinhlelo ezingama-905nm ze-lidar kuqokomisa ubuchwepheshe obuningana bokusebenzisa ubuchwepheshe obude (1550 / 1535nm) ngokwezokuphepha, ibanga, kanye nokusebenza ezimweni ezahlukahlukene zezemvelo. Lezi zinzuzo zenza amasistimu we-limidar ayi-1550 / 1535nm ikakhulukazi afanelekele izinhlelo zokusebenza ezidinga ukunemba okuphezulu nokwethembeka, njengokushayela okuzimele. Nakhu ukubheka okuningiliziwe kwalezi zinzuzo:
1. Ukuphepha kwamehlo okuthuthukile
Inzuzo ebaluleke kakhulu yezinhlelo ezingama-1550 / 1535nm ze-lidar ukuphepha kwazo kwamehlo abantu. Amagagasi amade awela esigabeni esidonswa kahle yi-cornea kanye nelensi yeso, ukuvimbela ukukhanya ukuthi kungafinyeleleki ku-retina ebucayi. Lesi sici sivumela lezi zinhlelo ukuthi zisebenze emazingeni aphezulu kagesi ngenkathi zihlala ngaphakathi kwemikhawulo yokuvezwa okuphephile, zizenze zilungele izinhlelo zokusebenza ezidinga amasistimu wokusebenza kwe-lidar aphezulu ngaphandle kokuyekethisa ukuphepha komuntu.
2. Ibanga lokuthola isikhathi eside
Ngenxa yekhono lokukhipha amandla aphezulu ngokuphepha, izinhlelo ezingama-1550 / 1535nm zingafinyelela ibanga elide lokuthola. Lokhu kubalulekile ukuthola izimoto ezizimele, ezidinga ukuthola izinto ezikude ukuze zenze izinqumo ezifika ngesikhathi. Uhlalunwe olunwetshiwe olunikezwe yilawa ma-wavelengths aqinisekisa ukulangazelela okungcono nokuphendula, uthuthukise ukuphepha okuphelele kanye nokusebenza kahle kwezinhlelo zokuhambisa ezizimele.
3. Ukusebenza okuthuthukile ezimweni zezulu eziphikisayo
Amasistimu we-Lidar asebenza kuma-wavelength angu-1550 / 1535nm abonisa ukusebenza okungcono ezimweni zezulu eziphikisayo, njengenkungu, imvula, noma uthuli. Lawa ma-wavelength amade angangena ekutholeni izinhlayiya zomoya ngempumelelo kunama-wavelength amafushane, alondoloze ukusebenza nokwethembeka lapho ukubonakala kumpofu. Lokhu kunamandla kubalulekile ekusebenzeni okungaguquki kwezinhlelo ezizimele, ngaphandle kwezimo zemvelo.
4. Okunciphisiwe okuphazanyiswe ukukhanya kwelanga neminye imithombo yokukhanya
Enye inzuzo engu-1550 / 1535nm lidar ukuzwela kwayo okuncishisiwe ekuphazanyisweni kokukhanya okukhona, kufaka phakathi ukukhanya kwelanga. Ama-wavelength athile asetshenziswa yilezi zinhlelo ajwayelekile emithonjeni yemvelo nezokufakelwa, enciphisa ubungozi bokuphazanyiswa obungathinta ukunemba kwemephu yezemvelo ye-lidar. Lesi sici sibaluleke ikakhulukazi ezimweni lapho ukutholwa okunembile nokuthola imephu kubaluleke kakhulu.
I-5. Ukungeniswa kwezinto ezibonakalayo
Yize kungeyona ukucubungula okuyisisekelo kwazo zonke izinhlelo zokusebenza, ama-waveghngth amade ka-1550 / 1535nm ama-lidar ama-lidar anganikeza ukusebenzisana okuhlukile ngezinto ezithile, okuhlinzeka ngokukhanya okuvela kuma-concleates noma ezindaweni ezithile (ngezinga elithile) kungazuzisa.
Naphezu kwalezi zinzuzo, ukukhetha okuphakathi kwezinhlelo eziphakathi kuka-1550 / 1535nm no-905nm zibandakanya nokucatshangelwa kwezidingo zezindleko nezicelo. Ngenkathi izinhlelo ezingama-1550 / 1535nm zinikeza ukusebenza okuphezulu nokuphepha, ngokuvamile zibiza kakhulu ngenxa yobunzima kanye nokukhiqizwa okuphansi kwezakhi zabo. Ngakho-ke, isinqumo sokusebenzisa ubuchwepheshe be-Lidar ye-Lidar engu-1550 / 1535nm bavame ukuncika ezidingweni ezithile zohlelo lokusebenza, kufaka phakathi uhla oludingekayo, ukucatshangelwa kwezokuphepha, izimo zemvelo kanye nezingqinamba zesabelomali.
