Nguva pfupi yadarika, iyo US Spirit probe yakapedza yakadzika space laser yekutaurirana bvunzo nezvivakwa zvepasi 16 miriyoni makiromita kure, ichiisa nzvimbo itsva yekuona yekutaurirana kurekodha.Saka ndezvipi zvakanakiraLaser kutaurirana?Zvichienderana nemisimboti yehunyanzvi uye zvinodiwa zvemishini, ndeapi matambudziko ainoda kukunda?Ndeipi tarisiro yekushandiswa kwayo mumunda wekutsvagisa nzvimbo yakadzika mune ramangwana?
Tekinoroji kubudirira, kwete kutya matambudziko
Kuongorora nzvimbo yakadzika ibasa rakaoma zvikuru munguva yevanoongorora muchadenga.Probes dzinoda kuyambuka nzvimbo iri kure, kukunda nharaunda dzakanyanyisa uye mamiriro akaomarara, kuwana uye kutumira data rakakosha, uye tekinoroji yekutaurirana inoita basa rakakosha.

Musi wa13 Gumiguru, kuferefeta kweMweya kwakatangwa, kutanga rwendo rwekuongorora rwunotora makore masere.Pakutanga kwemishoni, yakashanda neteresikopu yeHale paPalomar Observatory kuUnited States kuyedza tekinoroji yelaser yekutaurirana yakadzika, ichishandisa pedyo-infrared laser coding kutaurirana data nezvikwata zvePasi.Kuti izvi zviitike, iyo detector nemidziyo yayo yekutaurirana laser inoda kukunda angangoita mana marudzi ekuoma.Zvichienderana, chinhambwe chiri kure, chiratidzo chekumisikidza uye kupindira, bandwidth kudzikisira uye kunonoka, kudzikiswa kwesimba uye matambudziko ekupisa kupisa anofanirwa kutariswa.Vatsvakurudzi vakatarisira kwenguva refu uye vakagadzirira matambudziko aya, uye vakaputsa kuburikidza nenhevedzano yetekinoroji yakakosha, vachiisa hwaro hwakanaka hweMweya probe kuti iite yakadzika nzvimbo laser kukurukurirana kuyedza.
Chekutanga pane zvese, iyo Mweya detector inoshandisa yakakwirira-kumhanya data data tekinoroji, yakasarudzwa laser beam senzira yekufambisa, inehigh-simba lasertransmitter, uchishandisa zvakanakiraLaser kutapuriranamwero uye kugadzikana kwepamusoro, kuyedza kumisikidza laser yekukurukurirana zvinongedzo munzvimbo yakadzika yenzvimbo.
Chechipiri, kuitira kuti uvandudze kuvimbika uye kugadzikana kwekutaurirana, Mweya detector inotora tekinoroji inoshanda yekodha, iyo inogona kuwana yakakwirira yekufambisa data mukati meiyo shoma bandwidth nekugadzirisa iyo data coding.Panguva imwecheteyo, inogona kuderedza chiyero chekukanganisa uye kugadzirisa iko kurongeka kwekufambiswa kwedata nekushandisa tekinoroji yekumberi kwekukanganisa kugadzirisa coding.
Chechitatu, nerubatsiro rwehungwaru kuronga uye kutonga tekinoroji, iyo probe inoona kushandiswa kwakaringana kwezviwanikwa zvekutaurirana.Iyo tekinoroji inogona kugadzirisa otomatiki maprotocol uye mitengo yekufambisa zvinoenderana neshanduko yezvinodiwa zvebasa uye nharaunda yekutaurirana, nekudaro ichiva nechokwadi chemhedzisiro yekutaurirana pasi pesimba shoma.
Chekupedzisira, kuitira kukwidziridza kugona kwekugamuchira chiratidzo, iyo Mweya probe inoshandisa multi-beam yekugamuchira tekinoroji.Iyi tekinoroji inoshandisa akawanda anogashira antennas kuumba array, iyo inogona kuwedzera kugashira kwekunzwa uye kugadzikana kwechiratidzo, uyezve kuchengetedza yakagadzikana yekutaurirana yekubatanidza munzvimbo yakaoma yakadzika nzvimbo.
Zvakanakira zviri pachena, zvakavanzwa muchivande
The kunze nyika haina kuoma kuwana kutilaserndicho chinhu chakakosha cheyedzo yekutaurirana yakadzika nzvimbo yeMweya probe, saka ndeapi mabhenefiti ane laser kubatsira kufambira mberi kwakakosha kwekutaurirana kwechadenga?Chii chakavanzika?
Kune rimwe divi, kudiwa kuri kukura kwedata hombe, mifananidzo yakakwira-resolution uye mavhidhiyo enzvimbo dzakadzika dzekuongorora nzvimbo inosungirwa kuti ide mareti epamusoro ekufambiswa kwedata kune yakadzika nzvimbo yekutaurirana.Pamberi pechinhambwe chekufambisa mashoko icho chinowanzo “kutanga” nemakumi emamiriyoni emakiromita, masaisai eredhiyo haachina simba zvishoma nezvishoma.
Nepo kutaurirana kwelaser kuchikodha ruzivo pamafotoni, zvichienzaniswa nemasaisai eredhiyo, masaisai emwenje ari pedyo-infrared ane hutete hwewavelength uye frequency yakakwira, zvichiita kuti zvikwanise kuvaka "nzira huru" yedata ine hunyanzvi uye hwakatsetseka hwekufambisa ruzivo.Iyi poindi yakave yakasimbiswa mukutanga-yepasi-Earth orbit space kuyedza.Mushure mekutora matanho ekugadzirisa akakodzera uye kukunda kupindira kwemhepo, chiyero chekufambisa data chelaser communication system yakamboda kusvika ka100 kupfuura iyo yenzira dzekutaurirana yapfuura.
