NASA imatumiza chithunzi cha Mona Lisa mumlengalenga pogwiritsa ntchito kulumikizana kwa laser

NASA idagwiritsa ntchito ukadaulo watsopano waukadaulo wa laser kuti ipange chithunzi chakuda ndi choyera cha Mona Lisa mumlengalenga.

Chithunzi chakuda ndi choyera cha Mona Lisa chinawonekera mumlengalenga ndi NASA

Mona Lisa ndi chimodzi mwazithunzi zodziwika bwino kwambiri padziko lonse lapansi, zomwe zimakopa alendo zikwizikwi ku Louvre Museum ku Paris. Chithunzicho chinali chojambulidwa ndi Leonardo Da Vinci pakati pa 1503 ndi 1506 m'mafuta a popula. Imafotokozera mkazi wa Francesco del Giocondo, chifukwa chake utchulidwewo: La Gioconda. Kuti muyese njira yolankhulirana yochokera ku laser, NASA idatumiza chithunzi cha chithunzicho ku Lunar Reconnaissance Orbiter, chombo chomwe chimazungulira mwezi ndikusonkhanitsa zambiri za chinthu cha mwezi.

Lunar Reconnaissance Orbiter kumapeto kwa chithunzi cha Mona Lisa cha NASA

Kuzungulira mwezi si ntchito yophweka kwa Lunar Reconnaissance Orbiter, makamaka chifukwa cha mtunda womwe imalandira malamulo kuchokera ku bungwe lazamlengalenga. Malinga ndi NASA, alipo makilomita oposa 240,000s pakati pa Goddard Space Flight Center yomwe ili ku Greenbelt, Maryland ndi satellite ya mwezi.

National Aeronautics and Space Administration idatumiza uthenga kwa Mwezi wa Laser Orbiter wa Altimeter kudzera kulumikizana kwa laser. Bungweli lakhala likutsatira a LRO pogwiritsa ntchito matekinoloje opangidwa ndi laser kuyambira 2006. Mitundu ya Laser imatumizidwa pafupipafupi pakati pa LOLA ndi mabungwe amlengalenga, koma aka kanali koyamba kuti wina athe kukwanitsa kulumikizana njira imodzi.

Anapangidwa bwanji?

Chithunzi cha Mona Lisa chidagawika mapikiselo a 152 x 200, iliyonse ikufanana ndi mthunzi wa imvi. Makhalidwe a pixels adalumikizidwa kamodzi ndi bitrate ya 300 bit / s. Nthawi imayenera kukhala yolondola kwambiri kuti alole LOLA kuti amvetsetse momwe angagwirizanitsire chithunzicho. Kutengera kugunda kulikonse, mwezi woyenda mozungulira umatha kudziwa komwe ungaikire pixel iliyonse.

NASA idaganiziranso zam'mlengalenga kuti konzani zolakwika zilizonse za pixel, pogwiritsa ntchito njira yomweyi yogwiritsira ntchito ma CD ndi ma DVD. Nthawi yonseyi a LRO amapitilizabe kuchita zawo zatsiku ndi tsiku, zomwe zimaphatikizapo kupanga mapu a mwezi.

Kuyankhulana kwa Laser kudzakhala ndi tanthauzo lalikulu munjira zamtsogolo zolumikizirana

Kutsogoloku, kulumikizana kwa laser kulola kusamutsa deta kuma bitrate apamwamba kuposa kulumikizana ndi wailesi, anatero wasayansi wamkulu wa LOLA, David Smith. Posakhalitsa, ukadaulo wotere udzagwiritsidwa ntchito ngati njira yobwezera kulumikizana kwawayilesi, anawonjezera Smith.

Kanemayo pansipa amafotokoza mwatsatanetsatane momwe NASA idakwanitsira kuti awonetse chithunzi cha Mona Lisa mumlengalenga.
