- Ososayensi baseShayina benze isistimu ye-laser ethuthukisiwe engathwebula izithombe ezinokulungiswa okuphezulu ukusuka ebangeni elingaphezu kwamakhilomitha ayi-100.
- Isistimu yahlolwa eChibini laseQinghai, yathwebula imininingwane yehle yafika ku-1,7 mm kusetshenziswa isivalo sokuvula sokwenziwa sokwenziwa.
- Ubuchwepheshe busebenzisa i-laser enamandla amakhulu kanye neprosesa yedijithali yesikhathi sangempela ukukhiqiza izithombe ezibukhali kunamakhamera avamile.
- Naphezu kwenqubekelaphambili, izimo zezulu zingaphazamisa ukusebenza kwazo, okubonisa inselele ekusebenziseni kwazo ekugadweni.
I-China ithathe elinye igxathu ekuthuthukisweni kobuchwepheshe bokuqapha ngokwakhiwa kwe- Ikhamera ye-laser enembe kakhulu, ekwazi ukuthwebula izithombe ebangeni elikhulu kune 100 km. Lolu hlelo olusha lunamandla okushintsha indlela ukubuka ibanga elide, kusukela ekusetshenzisweni kwesayensi kuya ekusetshenzisweni kwezempi nokuvikeleka.
Abaphenyi abavela I-Aerospace Information Research Institute abavela e-Chinese Academy of Sciences baye bathuthukisa uhlelo olusekelwe kubuchwepheshe be-laser, ngokungafani namakhamera optical wendabuko, aluncikile kumalensi avamile. Ngenxa yalokhu, unganikela isinqumo esingakaze sibonwe, ngisho nokuvumela ukuhlonza ubuso bomuntu ezindaweni ezikude kakhulu.
Ukuhlolwa e-Qinghai Lake
Ukukhombisa ukusebenza kahle kwalolu hlelo, ososayensi benza izivivinyo ku I-Qinghai Lake, esenyakatho-ntshonalanga yeChina. Kusuka kwelinye lamabhange alo, idivayisi yakhomba isethi yama-prism akhanyayo atholakala 101,8 km kude. Umphumela wawumangalisa: ikhamera ikwazile ukuthwebula imininingwane emincane njenge 1,7 mm, into engafinyeleleki ezinhlelweni zendabuko.
Uhlelo aluhlinzeki nje kuphela ngezithombe ezibukhali emabangeni amade, kodwa futhi ingakala amabanga ngokunemba okungu-15,6 mm. Leli zinga lemininingwane selifikile Izikhathi ezi-100 ngaphezulu eyamakhamera ezinhloli avamile kanye nezibonakude zendabuko, ezinikeza kusengaphambili okungakaze kubonwe ekuthwebuleni izithombe zebanga elide.
Indlela lobu buchwepheshe obusha busebenza ngayo
Imfihlo yalolu hlelo ilele ekusebenziseni a i-synthetic aperture lidar, ubuchwepheshe obuvumela ukuthi izithombe zitholwe kusetshenziswa i-laser esikhundleni samalensi optical. Ukuze kuthuthukiswe ukunemba kwabo, abacwaningi bahlukanise i-laser beam kuhlu lwama-microlens angu-4x4. Lokhu kwandise ukuvuleka kwe-optical yesistimu. 17,2mm futhi 68,8mm, eyandisa inkambu yokubuka ngaphandle kokudela ikhwalithi.
Ngaphezu kwalokho, uhlelo luhlanganisa imojula ye-laser ekhipha amasignali anamaza angaphezu kuka-10 gigahertz. Ngenxa yalokhu okusha, kufinyelelwa isinqumo esinembe ngokwedlulele, okuvumela ukuhlonza izinto ezincane ngisho nemininingwane ku amasathelayithi avela eMhlabeni.
Izicelo kanye nemikhawulo
Lokhu kuthuthuka kwezobuchwepheshe kungashintsha indlela okwenziwa ngayo imisebenzi yezobunhloli kanye nokugadwa. Ngamakhono okubuka angenakuqhathaniswa, uhlelo lungasetshenziselwa ukuqapha amasathelayithi azungeza kancane, kuhlonzwe izakhiwo nokuhlaziya imininingwane ye ingqalasizinda ebalulekile ebangeni elide.
Nokho, ubuchwepheshe busenazo ezinye ukulinganiselwa okukhulu. Enye yezinselelo ezinkulu ukuncika ku- izimo zezulu. Ukuba khona kwamafu, izinguquko kungazelelwe emoyeni noma ukungcoliswa komoya can kuthinte ikhwalithi yezithombe. Ngaphezu kwalokho, ukulandelela izinto ezihambayo kulawa mabanga kumele inselele yokuhlela kanye nemishini okusamele ixazululwe.
Naphezu kwezinselelo, le ntuthuko imele Ingqophamlando ekuzweleni okukude kanye nasekuthuthukisweni kobuchwepheshe bokubhekwa nokuhlola.
Ngingumshisekeli wezobuchwepheshe oguqule izintshisekelo zakhe "ze-geek" zaba umsebenzi. Ngichithe iminyaka engaphezu kwengu-10 yempilo yami ngisebenzisa ubuchwepheshe obusezingeni eliphezulu kanye nokukitaza ngazo zonke izinhlobo zezinhlelo ngenxa yelukuluku lokufuna ukwazi. Manje sengiqeqeshelwe ubuchwepheshe be-computer nemidlalo yama-video. Lokhu kungenxa yokuthi sekuphele iminyaka engaphezu kwengu-5 ngisebenza ngokubhalela amawebhusayithi ahlukahlukene ezobuchwepheshe nemidlalo yevidiyo, ngenza izindatshana ezifuna ukukunikeza imininingwane oyidingayo ngolimi oluqondakala yiwo wonke umuntu.
Uma unemibuzo, ulwazi lwami lusukela kuyo yonke into ehlobene nesistimu yokusebenza ye-Windows kanye ne-Android yomakhalekhukhwini. Futhi ukuzibophezela kwami kuwe, ngihlala ngizimisele ukuchitha amaminithi ambalwa futhi ngikusize uxazulule noma yimiphi imibuzo ongase ube nayo kulo mhlaba we-inthanethi.
